What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on, while also maintaining the precise oil clearance needed to lubricate and cool the rotating assembly.

Does this bearing set come with all the necessary hardware for installation?

This listing is for the main bearing set itself. It's recommended to also have a new oil pump and a complete engine gasket set for a full rebuild. Always refer to the manufacturer's instructions for a complete parts list.

What does the 'P' in the Clevite MS1621P part number signify?

The 'P' in the Clevite part number typically indicates that these are standard size bearings. It's important to verify that your crankshaft journals are also standard size or within the acceptable tolerance for standard bearings before installation.

Product Details

If you're rebuilding the bottom end of your Allis-Chalmers engine with a D2800 or D2900 6-cylinder diesel, a solid set of main bearings is crucial for a smooth-running, long-lasting rebuild. These Clevite main bearings are designed to handle the stresses of continuous operation, ensuring your crankshaft spins true and your engine performs reliably.

Clevite is known for making well-built engine components, and this main bearing set is no exception. They are manufactured to meet the specific tolerances required for these Allis-Chalmers engines, helping to maintain proper oil clearance between the crankshaft and the engine block. This is key for reducing friction and wear, which directly impacts engine longevity and efficiency. The 'P' in the part number indicates a standard size bearing, so ensure this matches your crankshaft journal measurements for a direct fit during installation.

When you're putting in new main bearings, it's always a good idea to have a new oil pump and a complete gasket set on hand. Make sure to follow the manufacturer's installation instructions carefully, paying close attention to oil clearance specifications and proper lubrication before assembly.
