FAQ

Q1: How do I confirm that this push rod (129150-14400) fits my engine?
A: This push rod is specifically designed for the Yanmar 4TNV88 engine. To confirm fitment, please check the engine model plate on your equipment. It should clearly state “4TNV88.” If your engine is a variant like the 4TNV84 or 4TNV94, this part will not fit. For absolute certainty, you can also remove your old push rod and compare its length and diameter with the specifications listed.

Q2: What are the signs of a worn or damaged valve push rod?
A: A worn or bent push rod can cause a distinct ticking or tapping noise from the top of the engine, especially at idle. Other symptoms include rough running, loss of power, poor fuel economy, and in severe cases, a misfire. If you are performing a valve adjustment or a top-end engine overhaul, it is a best practice to inspect the push rods for straightness and wear, replacing any that show signs of damage.

Q3: Can I install this part myself, or do I need a professional mechanic?
A: Replacing a valve push rod requires disassembling the rocker arm cover and, in many cases, the rocker arm assembly. This is a moderate to advanced mechanical task that requires a torque wrench, feeler gauges, and knowledge of the correct valve lash adjustment procedure. While an experienced DIY mechanic can perform this job, we recommend that it be done by a certified diesel mechanic to ensure proper installation and prevent potential engine damage from incorrect valve timing.
