Description

When your Deutz F4L912 engine starts knocking or showing low oil pressure, worn main bearings are often the culprit. This 0.25mm oversize bearing kit gives you everything needed to restore proper clearances and quiet operation after the crankshaft journals have been turned to the first oversize dimension.

What You’re Getting

Complete set of 0.25mm oversize main bearings for all journal positions
Precision-manufactured to restore factory clearances with machined crankshaft
Quality materials that handle the heat and stress of diesel operation
Direct replacement kit – no guesswork about which bearings you need

Built for Real Farm Work

Deutz F4L912 air-cooled diesel engines are workhorses found in a wide range of agricultural and industrial equipment including tractors, construction machinery, generators, water pumps, and material handling equipment. These reliable engines are known for their durability, easy maintenance, and ability to operate in harsh conditions worldwide. The 4-cylinder F4L912 configuration powers everything from compact utility tractors to skid steers and telehandlers.

Made to Last

These bearings are engineered to handle the constant loads and temperature cycling that come with diesel engine operation. The bearing surfaces are designed to work with proper lubrication while resisting wear from the high pressures and temperature cycling that come with diesel combustion. Quality materials ensure long service life between overhauls.

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. This is precision work that requires proper measuring tools and machining knowledge. Always verify crankshaft journal dimensions before ordering – this kit is specifically for journals machined 0.25mm undersize from standard.
