MS-2339A-30 is used in engine rebuilds where crankshaft main bearing clearance must match an undersize journal specification. It supports proper oil film control and bearing surface conditioning in engines that have been machined for .030 in undersize main bearings.

Common Repair Uses

  • Restores crankshaft main bearing clearance after machining
  • Addresses bearing wear from high mileage or oil contamination
  • Helps correct scoring or seizure-related bearing damage
  • Supports rebuilds after crankshaft journal refinishing
  • Replaces worn OE-style main bearings in GM V8 engines

Installation Notes

Verify crankshaft journal size, bearing clearance, and engine code before installation. Clean all oil passages, inspect the crankshaft for taper or out-of-round conditions, and follow factory torque and lubrication procedures during assembly. Confirm that the engine has been machined for .030 in undersize bearings before using MS-2339A-30.

Quality Assurance

Clevite engine bearings are built around a durability-focused OE replacement design. The aluminum silicon bearing material and F1 coated surface are engineered to improve journal conditioning and resistance to wear in rebuilt engines.
