Iseki TS3110 Parts Catalog – Factory OEM Parts Breakdown

Lost half a Saturday chasing a part number that didn’t exist? I’ve seen it happen. A guy brings in a TS3110 with a bad injection pump, orders a “compatible” pump off the internet, and spends two days making it fit. A factory Iseki TS3110 Parts Catalog stops that before it starts. 210 pages of exploded-view schematics straight from Iseki – not a reprint, not a scan of a scan, but the original OEM document used by dealers in Japan.

Engine Assembly Breakdown: Cylinder Head to Fuel System

Fig. 1 drops you right into the cylinder head assembly – page 1 shows every bolt, gasket, and valve component. Fig. 7 covers the valve mechanism on page 13. If you are pulling the head on a TS3110, those two pages alone will save you a parts run. The catalog doesnt give torque specs (thats what a service manual is for), but it gives you the exact part number for each valve, spring, and keeper. No guessing which aftermarket kit fits.

Go deeper: Fig. 3 timing gear case, Fig. 6 crank shaft with piston and connecting rod, Fig. 8 oil and fuel filter fixing parts. Every single component is drawn with an item number that links back to a parts list. You want a fuel filter? Fig. 8 will show you the mounting bracket bolts you forgot to order.

Factory Parts Identification – What Aftermarket Diagrams Miss

An aftermarket parts website will show you a generic line drawing and a list of “fits many models”. That is worthless when you need the specific fuel filter head for a TS3110 with a mechanical lift pump. This catalog uses factory engineering drawings with the correct bolt lengths, washer counts, and seal locations. The cooling system (Fig. 10) shows the water pump housing, fan pulley, and belt routing – all with Iseki part numbers. You can cross-reference with other models like ISEKI TXG23 Tractor Parts Catalogue (Feb. 2003) or check the Directions for use of Parts Catalogue TXG23 for guidance on reading exploded views. Also see ISEKI TXG237 Parts Catalogue Directions for related model.

210 Pages of Exploded-View Schematics

210 pages. Not 40. Not “comprehensive coverage for most systems.” Every figure is a dedicated page: Fig. 12 fuel system, Fig. 14 injection pump, Fig. 22 radiator, Fig. 42 change gear system, Fig. 53 differential gear, Fig. 57 hydraulic system. Each system is broken down into sub-assemblies so you can rebuild step-by-step. Need the brake assembly? Fig. 56 and 56A cover E41/E43 and E21/E23 brakes separately because the parts differ. That level of detail is what you pay for – and what you get when you use a real OEM catalog.

Fuel System: From Fuel Tank to Injection Pump

Fig. 45 shows the fuel tank assembly with all mounting hardware. Fig. 46 covers the throttle system linkage. Then Fig. 12 takes you through the fuel lines, filters, and lift pump. Three separate pages for a system that many cheap catalogs stuff into one confusing diagram. The injection pump itself gets its own deep dive in Fig. 17 (proper), Fig. 18 (governor mechanical), and Fig. 19 (feed pump). If you are troubleshooting a no-start, you can trace the entire fuel path part by part.

Understand the Cooling System Before You Overheat

Radiator, water pump, fan, hoses – everything is in Fig. 22. The system is simple on the TS3110, but ordering the wrong radiator cap or fan blade because you guessed the thread pitch will cost you a week. This catalog gives you the Iseki part number, then you can cross-check with a supplier. No guesswork.

FAQ: Common Questions About This Catalog

Does this catalog include torque specifications for engine bolts?

No. This is a parts catalog, not a service manual. It lists part numbers and assembly breakdowns, not tightening values. You’ll need a factory service manual for torque specs.

How do I find which transmission gear set my TS3110 uses?

Check Fig. 48 and 48A for S and F-U types (page 127-131), then Fig. 49 for D, F-DU, LF-DU types (page 135-139). The catalog includes a note on serial number breaks in the hydraulic lift arm section (Fig. 59 vs 59A) – use those to match your tractor’s build date. If you don’t know your model variant, look for the type plate near the steering column. The catalog covers S, D, F-U, F-DU, LF-DU chassis. Serial number splits are printed on the figure pages themselves, not in a separate index. Pay attention to those; ordering wrong axle bracket (Fig. 27 vs 28) is a common mistake.

Can I use this catalog to rebuild the engine from scratch?

If you have a service manual for procedures and torque values, this catalog will let you order every single internal part. Pistons, rings, bearings, seals, gaskets – all listed with Iseki part numbers in Fig. 6 (crank/con rod/flywheel). The cylinder head section (Fig. 1) includes valve guides, seats, and springs. You’ll still need a service manual for clearances, but the parts list here is complete.

Are there wiring diagrams?

Yes, Fig. 64 through 67 cover electrical systems and wiring diagram. Fig. 66 shows the full chassis harness; Fig. 67 gives the circuit schematic. Battery system is Fig. 68. All part numbers for switches, lights, starter, generator are included.

If you need to identify parts correctly, stop guessing. Download the Factory Manual and keep it on your workbench – you’ll use it every time a TS3110 rolls in.
