Installation Notes and Tips

Verify crankshaft journal condition, housing bore size, and oil clearance before final assembly. Confirm the required bearing size from the engine machining work order, since this set is offered in standard and undersize selections. Check the 3.453 in. maximum flange outside diameter against the engine specification during mock-up. Use clean assembly practices and follow the engine builder’s torque and lubrication procedures.
