Part Number and Engine Application

The main part number is 129907-01100. This cylinder liner is prepared for Yanmar 4TNV98 and 4TNE98 engine applications. It may also be searched without hyphen as 12990701100, but this page should keep 129907-01100 as the main standard part number format.

Yanmar 4TNV98 and 4TNE98 engines can be used in compact equipment, forklifts, small excavators and industrial engine applications. The engine model alone should not be used as the only confirmation method. The removed liner sample and measured dimensions should be checked before shipment.

Key Checking Points Before Order

• Old cylinder liner part number or visible marking

• Engine model: Yanmar 4TNV98 or 4TNE98

• Required quantity: 4 pieces for one 4-cylinder overhaul set

• Bore size, outer diameter and total liner height

• Flange thickness and liner shoulder structure

• Photos of the old liner and engine nameplate

Cylinder Liner Replacement Notes

When replacing the cylinder liner, the piston, piston rings, liner seals, connecting rod bearings and gasket set should also be inspected. If the old liner has deep scoring, cavitation, overheating marks or uneven wear, the cause of failure should be checked before installing the new liner set.

Before assembly, clean the engine block seating area and check the liner fit carefully. Liner protrusion, bore clearance, sealing condition and cooling system condition should be checked according to the repair requirement. Poor installation or unresolved overheating problems can shorten the service life of the replacement liner.
