FAQ

Q1: How do I confirm this bushing will fit my Yanmar 3TNM72 engine?
A: Please verify your engine serial number and the original part number. The 119717-23911 is the standard con rod bushing for the 3TNM72. For absolute certainty, measure the inside diameter of your connecting rod small end and the outside diameter of your piston pin to confirm the bushing’s wall thickness matches your rebuild spec.

Q2: What is the recommended installation procedure for this bushing?
A: The bushing should be pressed into the connecting rod small end using an arbor press and the correct-sized driver tool. After installation, it is critical to ream or hone the bushing to the precise piston pin clearance specified by Yanmar (typically 0.02-0.05mm). Never attempt to hammer the bushing into place as this can distort the bore.

Q3: Can I use this bushing on a 3TNV72 engine?
A: The 3TNM72 and 3TNV72 are different engine series with distinct specifications. While they share the same displacement, internal components like the con rod and wrist pin size may differ. Please confirm your engine model is specifically 3TNM72 before purchase. Using the wrong bushing can lead to seizure or catastrophic rod failure.
