Description

When you’re facing an engine rebuild, the crankshaft journals have probably seen better days after thousands of hours turning your fields. If your machinist measures them at .010″ under standard size, you need bearings sized to match – and that’s exactly what this set gives you. These TISCO main bearings restore proper clearances and get your engine back to delivering the power you count on.

What You’re Getting

Complete bearing set for a full rebuild – one flanged thrust bearing and six standard main bearings
Precision .010″ undersized to match machined crankshaft journals
Off-center locating tabs on both halves prevent installation mistakes
OEM-quality construction that meets original John Deere specifications

Built for Real Farm Work

This bearing set fits the 381 CID six-cylinder diesel engines and the 404 CID six-cylinder diesel engines found in older John Deere tractors. These engines powered tractors through decades of field work, hay making, and loader operations – they’re built tough, but even the best engines need rebuilding eventually.

Made to Last

TISCO builds these bearings to handle the loads and stresses of agricultural work. The material composition and heat treatment match original specifications, so they’ll provide the same durability and service life as the bearings that came in your tractor originally.

Installation Notes

Your machinist will know the drill, but make sure the crankshaft journals measure exactly .010″ under before ordering. The off-center locating tabs make proper installation straightforward – they’ll only fit one way, so there’s no guesswork about bearing placement during assembly.
