All 97 pages of this Yanmar TB135 Parts Catalog (OEM #YOOF2161) focus on one thing: pinpointing the exact component for the 3TNE88-TB, TB1, ETB, ETB1, 3TNV88-QTB, QTB1, and QTB2 engine variants. Inside, you get exploded-view diagrams across every major assembly: cylinder block, gear housing, flywheel housing, cylinder head, camshaft, crankshaft and piston, lubrication oil system, cooling water system, and the complete fuel system from injection pump through governor and injector lines. Each figure pairs the drawing with a reference-numbered parts list and interchangeability marks, so you know which superseded part number fits your machine's serial range. Spec the correct V-belt (type A37.5) and confirm main metal undersize at 0.25 mm before you order. No more calling three dealers to verify whether last year's part number still fits. Bookmarked by assembly section; search any part number or description by keyword, open the right figure, and order with confidence.

Yanmar 3TNE88-TB, 3TNV88-QTB Common Problems This Manual Covers
Yanmar TB135 water pump part number unclear, multiple variants listed across serial number ranges p. 28
Open the Cooling Water System exploded view on page 28. Locate your water pump assembly in the diagram, note the Ref. No., then cross-reference the parts list for the correct assembly number. Check the Effective Machine Numbers column carefully — interchangeability marks indicate which part numbers apply to your serial range. The V-belt listed alongside is type A37.5 (page 29), so confirm that number too if you're replacing the drive system.
Manual Section: Cooling Water SystemCan't identify the correct head gasket kit part number for a full top-end overhaul p. 46
Go to the Gasket Set exploded view on page 46. The gasket kit listing consolidates head gasket, valve stem seals, O-rings, and oil seals into kit assemblies. Match your Ref. No. from the Cylinder Head & Bonnet diagram on page 10 to confirm the correct kit. Note any interchangeability marks — they indicate superseded part numbers for older serial ranges.
Manual Section: Gasket SetFuel injection nozzle part number needed but unsure which assembly fits after injector fouling p. 36
Check the Fuel Injection Valve exploded view on page 36. Identify the nozzle assembly Ref. No. and confirm the shim and spring part numbers alongside it — these are often replaced as a set. Cross-check the parts index to verify the nozzle assembly number against your engine model variant before ordering.
Manual Section: Fuel Injection ValvePiston ring oversize part number needed after cylinder bore inspection shows wear p. 25
Turn to the Crankshaft & Piston parts list on page 25. For TB135, 3TNE88-TB, TB1, ETB, and ETB1 models, the verified oversize is 0.25 mm — locate that oversize designation in the parts list and note the corresponding part number. For 3TNV88-QTB, QTB1, and QTB2 variants, use the equivalent listing verified on page 74 instead. Do not mix part numbers between these two model groups.
Manual Section: Crankshaft & PistonOil filter and oil pressure switch part numbers needed after lubrication system teardown p. 26
Open the Lub. Oil System section starting on page 26. The exploded view shows the oil pump assembly, filter, dipstick, oil lines, and oil pressure switch each with individual Ref. Nos. Locate each component in the diagram, then pull the corresponding part numbers from the list. Verify the interchangeability column if your engine has accumulated field modifications.
Manual Section: Lub. Oil SystemStarter motor brush and pinion part numbers needed after no-crank fault traced to worn starter p. 40
Find the Starting Motor exploded view on page 40. The diagram breaks out the armature, field coil, pinion, brushes, and magnetic switch as individually listed parts. Note the Ref. No. for each component you need, then confirm part numbers in the list. Check the Effective Machine Numbers column — brush and pinion specs can differ between engine sub-variants within this catalog.
Manual Section: Starting MotorFrequently Asked Questions

What head gasket part number fits the 3TNE88 cylinder head?
The cylinder head gasket (non-asbestos) for the Yanmar 3TNE88-TB engine is part number 129001-01340 (GASKET, NON-ASB.). The catalog lists this under the Cylinder Head & Bonnet section (Pages 10-11) with interchangeability marks for both 3TNE88-TB and related QTB variants. Always cross-reference the Ref. No. and interchangeability column before ordering to confirm fitment with your machine serial range.
What oversize piston and connecting rod parts are listed for the 3TNE88 crankshaft rebuild?
The Crankshaft & Piston section (Pages 24-25) lists oversize pistons and rings alongside standard connecting rods. The catalog includes undersize main bearing sets available at 0.25 mm undersize for crankshaft journals. Each oversize/undersize part is identified by Ref. No. and interchangeability marks so you can confirm which undersize applies to your serial-number range. Confirm main metal undersize at 0.25 mm before ordering.
What fuel injection pump components are covered in this parts catalog for the 3TNE88?
The Fuel Injection Pump section (Pages 30-33) covers: pump assembly, individual plungers, delivery valves, control rack, and the fuel cutoff solenoid. The Governor section (Pages 34-35) lists weights, control levers, springs, and the control pinion. The Fuel Injection Valve section (Pages 36-37) lists nozzle assemblies, shims, and fuel pipes.
