Yanmar 4TNE88 4TNV88 Engine Cylinder Liner 129907-23080

Yanmar 4TNE88 / 4TNV88 Cylinder Liner 129907-23080

The 129907-23080 cylinder liner is supplied for Yanmar 4TNE88 and 4TNV88 diesel engine repair. It is used during engine overhaul when the original cylinder bore is worn, scratched, damaged or no longer suitable for stable piston ring sealing performance.

This page is focused on the Yanmar 88 series engine cylinder liner application, which is different from the 4TNE94 / 4TNV94 liner page. Before ordering, please confirm the old liner sample, engine nameplate and required liner specification to reduce wrong-part risk.

Part Number and Engine Application

The main part number for this page is 129907-23080. It is used as a cylinder liner reference for Yanmar 4TNE88 and 4TNV88 diesel engine applications. This page does not use an additional Ref Cross number because no reliable interchangeable cross number has been confirmed for this product page.

Difference from the 4TNE94 / 4TNV94 Liner Page

This page should not be treated as the same product as the Yanmar 4TNE94 / 4TNV94 cylinder liner page. The 272 page is for 4TNE88 / 4TNV88 engine applications with part number 129907-23080, while the 271 page is for 4TNE94 / 4TNV94 engine applications with part number 129930-01100.

Keeping these two pages separate is acceptable because they target different Yanmar engine series, different liner references and different engine repair searches. To avoid duplicate content, this page uses 88 series wording, 129907-23080 part number signals and separate confirmation notes.

Key Checking Points Before Order

Cylinder liners should not be confirmed only by the engine model. For accurate matching, please check the removed liner dimensions, liner type and engine application before shipment. This is especially important when the engine has been repaired before or when the old part number is not visible.

Engine Check: Confirm whether the engine is 4TNE88 or 4TNV88.

Old Sample Check: Provide clear photos of the removed cylinder liner from multiple angles.

Dimension Check: Confirm inner diameter, outer diameter, total height and flange size.

Liner Type Check: Confirm whether the required liner is finished or semi-finished.

Repair Check: Check the piston, piston rings and cylinder block condition together before rebuilding the engine.

Cylinder Liner Replacement Notes

When replacing the 129907-23080 cylinder liner, the piston, piston rings, cylinder block condition and engine overhaul requirements should be checked together. If the liner is supplied as a semi-finished type, machining may be required before final installation.

For repair work, the liner should be selected together with the piston and ring condition. If the old liner has abnormal wear, scoring, overheating marks or poor sealing traces, the related piston and ring set should also be inspected before rebuilding the engine.
