Description

If you’ve been noticing a metallic knock or unusual vibration from your Kubota engine, it might be time to check those thrust washers. These small but critical pieces control how much your crankshaft can move back and forth—what mechanics call endplay. When they wear out, your crankshaft gets loose and starts banging around, which can lead to expensive damage if you don’t catch it early.

What You’re Getting

Precision-sized washer that controls crankshaft endplay and prevents damage
Direct OEM replacement that fits perfectly without modifications
Sold individually so you can replace just what you need
Made from durable materials that handle the constant pressure and heat

Built for Real Farm Work

This thrust washer fits a wide range of Kubota diesel engines found in everything from compact utility tractors to mid-size workhorses. Whether you’re running a B-series compact for mowing and loader work or a larger machine for serious field operations, these engines power through thousands of hours of demanding farm tasks.

Made to Last

Thrust washers live in one of the toughest spots in your engine—right where the crankshaft meets the engine block. They handle enormous pressure every time a piston fires and need to maintain precise tolerances despite constant heat and oil exposure. This washer is built to OEM specifications to handle those demanding conditions.

Good to Know

Thrust washer replacement is definitely an internal engine job that requires splitting the case, so it’s usually done during a major rebuild or when the engine is apart for other work. If you’re checking endplay with a dial indicator and find it’s out of spec, don’t put off the repair—a loose crankshaft can destroy main bearings and even crack the block.
