Description
When your diesel engine starts knocking or the oil pressure drops, it’s often the rod bearings crying for help. These bearings live between the connecting rods and crankshaft, spinning thousands of times per minute while carrying the full load of combustion forces. A worn bearing set means metal-on-metal contact that’ll destroy your crank if you keep pushing it, and nobody wants to be shopping for a rebuilt engine during planting season.
What You’re Getting
- Complete bearing set for all six cylinders in one kit – no guessing about quantities
- Precision .030 inch oversize dimensions for engines with machined cranks
- High-quality bearing material designed to handle diesel engine loads and heat
- Direct replacement for A504BD turbocharged diesel applications
Built for Real Farm Work
This kit fits the A504BD 6-cylinder turbocharged diesel engine found in various agricultural tractors. These engines were built to handle the demanding loads of field work, whether you’re pulling heavy implements through tough soil or running a PTO-driven baler all day. The turbocharger adds extra power but also increases the stress on internal components like these rod bearings.
Made to Last
Rod bearings in diesel engines take tremendous punishment from high compression ratios, heavy loads, and constant operation. These replacement bearings use modern materials and manufacturing techniques to provide reliable service under the toughest conditions. The precise .030 oversize dimension accommodates crankshafts that have been turned to remove wear and restore proper clearances.
Installation Notes
This is a .030 oversize bearing set, which means your crankshaft needs to be machined to the proper undersize dimension by a qualified machine shop before installation. Always check bearing clearances with plastigage during assembly, and make sure your oil pump and passages are clean before firing up the rebuilt engine.
