Description

When your Deutz engine starts developing that telltale knock or you notice oil pressure dropping, it’s time to address worn main bearings before they take out your crankshaft. This 0.25mm undersize main bearing kit restores proper clearances and gets your engine back to running smooth and strong.

What You’re Getting

Complete bearing set sized 0.25mm under standard to work with reground crankshafts
Precision-manufactured bearings that restore proper oil clearances and pressure
Quality construction designed to handle the loads and heat cycles of diesel operation
Direct replacement that fits without modifications when your crank has been properly machined

Built for Real Farm Work

These bearings fit the reliable Deutz F3L912 air-cooled diesel engines found in a wide range of agricultural and industrial equipment including tractors, construction machinery, generators, water pumps, and material handling equipment. These engines are known for their durability, easy maintenance, and ability to operate in harsh conditions worldwide.

Made to Last

These bearings are manufactured to handle the constant loads that occur in diesel engine operation, with bearing surfaces designed to work with proper lubrication while resisting wear from the high pressures and temperature cycling that come with diesel combustion. The 0.25mm undersize specification ensures proper fit when your crankshaft journals have been turned to restore roundness and surface finish.

Installation Notes

Installation requires complete engine disassembly and is typically performed during major engine overhauls along with other wear components like bearings, rings, and gaskets. Always measure your crankshaft journals with a micrometer to confirm they’ve been turned 0.25mm under before ordering. Check bearing clearances with plastigauge during assembly to ensure everything’s within specification.
