Buying a replacement part for a Yanmar tractor is not like buying a phone case. The wrong part either will not bolt on at all, or it fits and quits after a season of mowing. The parts below are all confirmed to fit specific Yanmar models, and the short answer is this: match the OEM number on your old part to the number listed here before you spend anything. Everything else is second.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see exactly which engine and chassis codes each part covers, what it is made of, and where the honest weak spots sit. That fitment-first approach is the whole point of this breakdown of the yanmar tractor parts list.

How To Choose The Best Yanmar Tractor Parts
Your tractor does not care what brand name is printed on the box. It cares whether the mounting holes line up and whether the part does its job under load. Pick by fitment, then by build, and you will avoid the most common and most expensive mistake in this category: buying a part for a machine that is almost yours.
Start with the OEM number, not the model badge
Every original part on your Yanmar carries a manufacturer part number, often stamped or cast into the housing. Write that number down before you open a single listing. A part listing that names your engine code — something like 3TN66 or 4JH2E — is confirming a match that was checked against a real parts catalog, not guessed from a photo.
Yanmar built the same basic tractor under several codes across overlapping years, so two machines that look identical from the driver’s seat can take different filters. The OEM number cuts through that ambiguity in seconds.
Know which electrical and fuel specs decide the purchase
For a starter motor, four numbers rule the fit: voltage in volts, power rating in kilowatts, rotation direction, and pinion tooth count. Get any one wrong and the motor either will not engage the flywheel or spins the wrong way. For a fuel shut-off solenoid, the return-spring force in newtons and the travel in millimeters are what determine whether the fuel rack closes cleanly when you turn the key off.
Decide how much aftermarket risk you accept
Genuine parts carry the Yanmar name and a known part number. Aftermarket parts can match that number and cost less, but the build quality varies more widely. That is not a reason to avoid them — plenty of owners run aftermarket fuel and hydraulic parts for years — it is a reason to read what other buyers report about longevity before you commit.

Detailed Reviews
1. SCITOO Starter 3TN66 SHI0102
Our pick — 4.0+★ from 450+ verified ratings; the strongest balance of quality and price.
A 12V, 0.9kW starter that cranks 3TN66, 3TNA68 and 3TNA72 Yanmar engines instead of clicking.
If your 3TN66, 3TNA68 or 3TNA72 engine clicks and nothing else happens, this starter is the fix. The SCITOO starter is rated at 12V and 0.9kW, and it turns clockwise, which is the direction a Yanmar flywheel expects. The pinion carries 9 teeth, so it meshes where the original one did. It covers 3TN66 engines from 85-on and also the 3TNA68 from 86-on and 3TNA72 from 84-on, which means a wide spread of mid-size Yanmar machines are covered by one box.
What makes it a serious pick rather than a cheap swap is the way it cranks. Functionality is the thing it does best — it fires the engine reliably, and the fit lands right on the original mounting points. Installation is straightforward too: it arrives with a matching mounting bracket and pre-drilled wiring ports, so it bolts into the original location with common hand tools and no drilling or adapters.
The catch is that it is heavy. Its build quality and value draw split opinions among owners — some units keep cranking for seasons and some do not. Buy it as a solid mid-range replacement, not a lifetime one.
What it does right
- 12V, 0.9kW, clockwise rotation and a 9-tooth pinion match the Yanmar spec
- Covers 3TN66 85-on, 3TNA68 86-on and 3TNA72 84-on engine codes
- Bracket, pre-drilled wiring ports and common-tool installation
- One-year unlimited-mileage guarantee from the maker
- Coated housing and reinforced internal components
Where it asks patience
- 6.6 pounds means one-handed fitting gets tiring
- Long-term durability divides owners — some report it going strong, some do not
- You get what you pay for, so treat it as a replaceable wear part
Go for it when: your Yanmar has a 3TN66, 3TNA68 or 3TNA72 engine and the old starter only clicks.
Hold off when: you want a starter to outlive the tractor — this one earns its keep on reliability, not on a lifetime promise.
2. 129470-55810 Fuel Filter 129470-55703 Genuine Parts OEM
A Yanmar-boxed fuel filter that replaces five superseded part numbers, so the fit is known before it ships.
This is a Yanmar filter with the Yanmar name on the box, not an aftermarket copy that lists a compatible number. The manufacturer part number is 129470-55810, and it replaces 129470-55700, 129470-55701, 129470-55702 and 129470-55703. That means if your old filter carries any of those five numbers, this one drops straight into the housing. It is specified for 3JH2E, 3JH2-TE, 3JH3E-YEU, 3JH4E, 4JHE, 4JH-TE, 4JH-HTE, 4JH-DTE, 4JH2E, 4JH2-TE, 4JH2-HTE, 4JH2-DTE, 4JH2-UTE, 4JH2-UTB and 4JH3E-YEU engines — mostly the marine diesel side of the Yanmar family.
At 12 ounces it is lighter than the 15.2-ounce All States air filter also on this page, so it is an easy one-hand swap in a tight engine bay. The outer material is stainless steel, which matters on a boat where salt air eats mild steel for breakfast. It is a single-count item, so order the number of filters you actually plan to change.
Why genuine wins here: a fuel filter is a part you cannot inspect from the outside. Buying the Yanmar-branded unit removes the guesswork about pleat count, seal fit and bypass behavior — the specs and the name come from the same company that built the engine.
The trade-off to plan around: this is one filter, not a service kit. You still need to source your oil filter and any crush washers separately, so build a proper service list before the boat goes back in the water.
Made for the owner who: runs a 3JH or 4JH series marine diesel and refuses to gamble on fuel cleanliness.
Not the pick if: you are servicing a YM-series compact tractor — the fitment codes here do not cover that engine family.
3. Air Filter 124295-12560
One air filter that fits nine YM models, from the YM195 through the YM3000.
There is no mystery to what this does. It is the air filter your YM-series tractor breathes through, and it is confirmed to fit the YM195, YM240, YM1500, YM1600, YM1700, YM1900, YM2000, YM2500 and YM3000. That is nine separate models on one part number, which is rare in this category and genuinely useful if you own two older Yanmars.
It carries the OEM equivalent numbers 124295-12560 and 124763-12510, so pull your old filter and check those digits against the stamp. The All States build weighs 15.2 ounces — heavier than the 12-ounce genuine fuel filter above — and that mass usually means more filter media inside, which is what you want when you are mowing dry summer grass and the dust is coming up in clouds.
What loses people money here is not the filter, it is assumption. The YM3000 and the YM195 are both on the list, but that does not mean every YM model between them is. Confirm your model number first, then buy — the listing is specific about which nine it covers and honest about nothing else.
The best argument for it: cross-model coverage. If you keep a couple of YM tractors alive on a smallholding, one part number on the shelf feeds both of them.
One thing to keep straight: it is an aftermarket filter carrying OEM equivalent numbers, not a Yanmar-boxed unit. That is normal for air filters, but check the seal seats flush in the housing before you bolt the cover down.
Right for: anyone who owns one of those nine YM models and wants a straightforward replacement without hunting for a genuine listing.
Wrong for: later Yanmar engines — the 3TN and 4JH codes on this page take different filters entirely.
4. Genuine OEM Yanmar Hydraulic Oil Filter #198167-24900!
A genuine M16 x 1.5 spin-on hydraulic filter that keeps metal dust out of your pump and hitch circuit.
Hydraulic fluid is the one system on a compact tractor that quietly gets worse when nobody watches it. Metal dust from cylinders and seal material circulate in the oil, and the filter is the only thing standing between that grit and your pump. This is the genuine Yanmar part with number 198167-24900, and it carries a one-year warranty from the manufacturer.
The thread is M16 x 1.5 — that is the diameter in millimeters plus the thread pitch — and it determines whether the filter spins on cleanly by hand. Get that wrong on a spin-on canister and you will cross-thread the housing, which is a far more expensive fix than the filter itself. It is listed as compatible with Yanmar and Cub Cadet tractors, so a machine rebadged under either name is covered.
Yanmar’s own listing points you to the original equipment owner’s manual to confirm compatibility, and that is advice worth taking literally. Hydraulic filter specs were revised across model years, and the manual is the only source that knows which revision your tractor rolled out with. Filter changes are one of the simplest maintenance jobs on the whole machine — cap the fluid, spin it off, spin the new one on — which makes it an easy thing to get right if you start with the right number.
What you are paying for: the Yanmar name and part number on a filter that seals to the exact thread spec, plus a stated one-year warranty.
Before you order: this is a hydraulic filter, not an engine oil filter and not a fuel filter. Mixing those three up is the most common cause of a return, so read the old canister before you click.
Pick this if: your manual points at 198167-24900 and you want a genuine part with a warranty behind it.
Look elsewhere if: you are chasing an engine oil or fuel filter — this canister does not serve those circuits.
5. Fuel Shut Off Solenoid M810324 1503ES-12S5SUC12S
A 12VDC solenoid with an 80N hold and 17N return spring that closes the fuel rack when you cut the key.
When a diesel keeps running after you switch off, the fuel shut-off solenoid is almost always the reason. This MaySpare unit runs on 12VDC, replaces 119233-77932 and 1503ES-12S5SUC12S, and states its spring numbers openly: 80 newtons of hold force and a return spring rated at 17 newtons with 25MM of travel. Those figures are the language of a working solenoid — enough hold to keep the fuel rack open while running, enough spring to snap it shut when power drops.
What owners mention most is the fit. It lands in the factory position, which is the whole battle with a solenoid, and it is listed for the Yanmar TB235 3TNV88-BPTB2 engine as well as John Deere 4200 through 4700 machines and equipment like excavators and backhoes. No professional install is required — it is an OEM replacement, so it swaps out rather than gets adapted.
Here is the part most listings will not tell you. Quality and durability are the split point — plenty of these units go in and work, and a share of them do not hold up over time. That is a real consideration on a 12VDC coil, so keep your old solenoid until the new one has proven itself over a few start-stop cycles. The price reflects that risk rather than hiding it.
Strongest card: a factory-position fit plus published spring and travel specs, which means you can verify the coil matches the original before it ever touches the engine.
Honest hesitation: the painted cover and strong return spring are described in detail, but long-term life on this unit is a gamble — treat it as a maintenance part you may revisit.
Reach for this when: your Yanmar TB235 or John Deere 4200 to 4700 series will not shut off, and you want a like-for-like swap.
Weigh it first if: you want a part you never think about again — the cost saving here comes with some risk of a repeat job.
6. JEENDA Water Pump CH12859 721250-42700
A cast water pump that fits Yanmar 1700 through 3110 and John Deere 850, 900HC, 950 and 1050 compacts.
Water pumps fail in a predictable way: a weep from the seal, a growl from the bearing, then a temperature gauge that climbs and will not come back down. The JEENDA pump carries part number CH12859, which also crosses to 721250-42700. It fits Yanmar compact tractors 1700, 2000, 2010, 2210, 2310, 2420, 2500, 2610, 3000 and 3110, and it covers the John Deere 1050, 850, 950 and 900HC compact utility tractors too — machines that were built on Yanmar internals.
That shared fitment is the point worth pausing on. If you have been hunting a cooling part for a badge-engineered John Deere compact, this one listing covers both names. It weighs 1.02 kg, which is a substantial cast body rather than a stamped shell, and it is a single-count item.
The honest limitation is coverage on the outside edges. The range runs 1700 through 3110, so a machine that sits outside those exact codes is not covered by this listing, even if it looks similar under the hood. Coolant is unforgiving of a slightly wrong pump — check the part number on your old housing against CH12859 and 721250-42700 before ordering.
Why it earns a spot
- Dual fitment: Yanmar 1700 through 3110 and John Deere 850, 900HC, 950 and 1050
- Cross-references both CH12859 and 721250-42700
- 1.02 kg body — a solid cast unit, not a thin shell
- Covers the 2010, 2210, 2310 and 2420 models many generic pumps skip
What to watch
- Only the listed model codes are confirmed — an YM outside that range is not covered
- Aftermarket brand, so inspect the seal face before you install it
Best fit for: a compact tractor owner whose temperature gauge started climbing and who needs the CH12859 pump.
Think twice if: your Yanmar is a 3TN or 4JH engine — this pump is spec’d for the YM compact series.
7. 159750 Adjustable Side Link CAT I
A CAT I side link that adjusts from 7.5 to 12.5 inches so you can level a mower or blade.
A three-point hitch only works as well as its side link lets it. This is an aftermarket Yanmar Category 1 adjustable side link supplied with the pin, and it changes length from a 7.5-inch minimum body to a 12.5-inch maximum. That range is what lets you tilt an implement left or right to match the ground instead of dragging it at an angle.
It is built for compact tractors from 15HP to 40HP, and it swaps with part numbers 794190-72101, 79419072101, ASL750, 159750, 159-750 and S.70515 — so if your parts manual lists any of those, this replaces it. The three hitch holes measure 0.570 inches across, which is the pin size the link is drilled for.
Weight is the honest split here. At 3.99 pounds it is much lighter to swing onto a hitch arm than the 6.6-pound SCITOO starter, so fitting one on your own is no hardship. What it is not is a precision surface part — expect an aftermarket finish, and check the pin fits the hole before you rely on it under a heavy load.
The useful detail: an adjustable body from 7.5 inches to 12.5 inches, plus the three 0.570-inch holes, covers the CAT I hitch on most compact tractors in that 15HP to 40HP band.
Check before you commit: the listing names Yanmar and Kubota, but it is an aftermarket part — confirm the interchange number on your own manual, and inspect the pin fit on arrival.
The right buy for: a compact tractor owner who wants to level implements and finds a fixed side link too limiting.
Not for you if: you run a Category 2 hitch — this link is drilled and sized for CAT I only.
Know the Specs
Starter Motor Ratings
Four numbers decide whether a starter fits. Volts tells you the electrical system it expects — 12V on all the compact tractors covered here. Power rating in kilowatts tells you how much cranking muscle it has. Rotation direction, shown as CW for clockwise, must match your flywheel or the motor spins the wrong way. Pinion tooth count is the physical mesh — a 9-tooth pinion engages a 9-tooth ring, not a 10-tooth one.
Solenoid Force and Travel
A fuel shut-off solenoid holds the fuel rack open while the engine runs and drops it closed when power is cut. Hold force, measured in newtons, is how hard it keeps the rack open — 80 newtons on the MaySpare unit here. The return spring, rated 17 newtons, is what pulls it shut. Travel, in millimeters, is how far the plunger moves. Match all three to your original part and the engine will start and stop on cue.
Filter Part Numbers and Cross-References
Yanmar filters carry a manufacturer number like 129470-55810, and that number is often superseded by a newer one. A good listing shows both the current number and the numbers it replaces, so an older tractor with an older filter code still gets a match. Always read the stamp on your old filter — the number cast into the canister is the source of truth, not the model year of the machine.
Three-Point Hitch Dimensions
A side link is defined by its length range and its hole diameter. The 7.5-inch minimum and 12.5-inch maximum tell you how much tilt adjustment you get. The 0.570-inch hole size tells you which hitch pin it accepts. Category 1 hitches are the standard on compact tractors in the 15HP to 40HP band, and a Category 2 link will not fit those pin sizes.
Common Questions
How do I know which Yanmar part number my tractor needs?
Will a 9-tooth starter pinion fit my Yanmar engine?
Is a genuine Yanmar filter worth it over an aftermarket one?
Why does my diesel tractor keep running after I turn the key off?
Can I install a Yanmar starter or solenoid myself?
What is the difference between a Category 1 and Category 2 side link?
How often should I change the hydraulic oil filter on a compact tractor?
Will a water pump for a Yanmar also fit a John Deere compact tractor?
What should I do if the air filter does not seal properly in the housing?
Are aftermarket Yanmar parts reliable enough for everyday use?
The Bottom Line
If you want the part that solves the most common breakdown on a Yanmar, the SCITOO Starter is the sensible first call — 12V, 0.9kW, clockwise rotation and a 9-tooth pinion, with a mounting bracket and pre-drilled wiring ports that make fitting it a one-person job. When your priority shifts from cranking to fuel cleanliness on a marine diesel, the genuine 129470-55810 fuel filter is the safe order, because the Yanmar name and part number remove every doubt about what lands on your doorstep.
For the owner chasing a temperature gauge that will not drop, the JEENDA CH12859 water pump covers an unusually wide spread of Yanmar and John Deere compact models. And if a fixed hitch arm has been fighting you all season, the 159750 adjustable side link trades 3.99 pounds of steel and a 7.5-to-12.5-inch range for the ability to level any implement you hang on the back. Match the OEM number first, and every one of these is a straightforward job.
