When you’re doing an engine rebuild and the crankshaft journals measure a few thousandths under spec, you need bearings that match the actual dimensions—not what the manual says they should be. This .010″ undersized thrust main bearing is what you reach for when your machinist has cut the crankshaft thrust surfaces to clean them up, or when wear has taken its toll over the years.
What You’re Getting
- Precision-manufactured .010″ undersized bearing that matches machined crankshaft dimensions
- Quality construction that handles the axial loads and heat cycles of diesel engine operation
- Direct replacement design that installs just like the original bearing
- Proper oil clearances when used with machined crankshaft surfaces
Built for Engine Rebuilds
This bearing is specifically sized for John Deere diesel engines where the crankshaft has been machined or where normal wear has reduced the journal diameter. The thrust bearing controls crankshaft end play and takes the beating from clutch engagement, flywheel loads, and the constant back-and-forth forces that come with engine operation under load.
Made to Last
Engine bearings operate in one of the harshest environments in your tractor—constant heat, pressure, and the shock loads that come with heavy work. This bearing uses quality materials and proper clearances to handle those demanding conditions while keeping oil flowing where it needs to go.
Good to Know
Always check crankshaft measurements carefully before ordering—using the wrong size bearing means either too much clearance (low oil pressure) or too little clearance (bearing failure). Your machinist should provide the exact measurements after any crankshaft work. Install with proper assembly lube and follow torque specs exactly during reassembly.
