Description
Overview:
The Crankshaft Main Bearing Gear End (U/S010) 268692 is a genuine Lister Petter component for Petter AA and AB diesel engines, also compatible with the Petter AC. It is a robust metal bearing shell fitted at the gear end of the crankshaft to support the journal, maintain oil film, and keep the rotating assembly in correct alignment. Marked U/S010, it suits a crankshaft reground to 0.010 in undersize (approx. 0.25 mm). This OEM part carries reference AAC32/010 and is designed for reliable operation in industrial and vintage applications. Supplied as unused old stock, so light tarnishing or storage marks may be present, which does not affect function. Ideal for maintenance, rebuilds, and restoration where correct clearances and durability are required.
Key Features:
- Genuine Lister Petter part for assured compatibility and build quality (Ref: 268692, OEM No. AAC32/010)
- U/S 0.010 in undersize (approx. 0.25 mm) for reground crankshaft journals
- Gear-end main bearing shell to support the crankshaft and maintain alignment
- Durable construction suited to continuous-duty diesel engine use
- Helps maintain correct oil film thickness for reduced wear and smooth running
- Fits Petter AA/AB/AC blocks where the journal has been ground by 0.010 in (0.25 mm)
- Unused old stock; cosmetic tarnish from storage may be visible but is normal
- Straightforward to fit during overhaul; align tangs and oil feed correctly and check clearances to the workshop manual
Typical Applications:
