Description
Overview:
These Centre Main Bearings U/S 040 are genuine Lister Petter components for restoring correct crankshaft support in Lister LD2 and SL2 diesel engines. Supplied as metal bearing shells, they replace worn centre main bearings to bring back proper oil clearance and smooth rotation. The U/S 040 designation indicates an undersize of 0.040 in (1.02 mm) to suit reground crank journals. As New Old Stock, they provide original factory specification and fit, helping maintain engine reliability and performance in plant, agricultural, and stationary machinery powered by LD2 or SL2 engines. Durable construction and accurate sizing reduce friction, support the crankshaft under load, and protect against premature wear when installed with the correct oil and torque settings.
Key Features:
- Genuine Lister Petter part for assured fit and material quality
- U/S 0.040 in (1.02 mm) sizing for reground crankshafts on the centre main journal
- Durable metal bearing shells for consistent oil film and long service life
- Factory geometry to help maintain correct oil clearance and crank alignment
- Helps reduce vibration and friction, aiding smoother, quieter running
- Suitable for engine rebuilds or preventative maintenance on LD2 and SL2 units
