Built for Heavy-Duty Work

The A504BD is a workhorse engine that powers tractors handling serious field work, from heavy tillage to running large implements under load. These turbocharged diesels generate substantial heat and pressure, which makes quality bearings essential for long-term reliability. This bearing kit is engineered to handle the demanding conditions these engines face day after day.

Made to Last

Engine bearings take a beating in agricultural applications—constant load changes, temperature swings, and long hours under stress. These bearings use materials specifically chosen for their ability to handle high loads while maintaining proper oil film thickness. The precision manufacturing ensures consistent wall thickness and proper crush for reliable installation and long service life.

Installation Notes

Installing oversized bearings requires the crankshaft journals to be machined .010″ undersize by a qualified machine shop. Always check journal condition and measure clearances with Plastigage before final assembly. Take your time with torque specifications—proper bearing crush is critical for oil pressure and engine longevity.
