Description

When your tractor starts knocking on cold mornings or you’ve noticed oil pressure dropping, it’s often worn main bearings crying for help. Rebuilding an engine means getting the crankshaft clearances back to where they should be, and if your crank has been turned .030 oversize, these bearings are exactly what you need to bring that old Massey Ferguson back to life.

TISCO quality construction that meets or exceeds OEM specifications
Proper clearances to restore oil pressure and eliminate bearing knock
Direct replacement bearings – no modifications or special tools needed

Built for Real Farm Work

This bearing kit fits Massey Ferguson tractors that have had their crankshafts machined .030 inch oversize during rebuild. Whether you’re restoring a classic MF 35 for hobby farming or bringing an MF 135 back to daily work status, these bearings provide the foundation for reliable engine operation. TISCO has built their reputation on providing quality engine rebuild parts that farmers can count on.

Made to Last

Engine main bearings take the full force of combustion loads and must handle thousands of hours of constant rotation. These bearings feature proper material composition and precise manufacturing that delivers smooth operation and long service life. The .030 oversize design ensures proper clearances with your turned crankshaft for optimal oil film and bearing protection.

Installation Notes

Installing main bearings is serious engine work that requires proper tools, torque specifications, and careful attention to clearances. Always verify your crankshaft has been turned exactly .030 oversize before installation. Check bearing clearances with Plastigage and follow your engine manual’s torque sequence. If you’re not comfortable with internal engine work, this is a job for an experienced mechanic.
