What engines do these ACL Race Series main bearings suit?
These main bearings are listed for RB30 engines. Always confirm the bearing part number, crankshaft journal size and required bearing size before ordering.
How do I choose the correct size main bearings?
Bearing size should be selected from actual crankshaft journal measurements and the oil clearance required by your engine builder. STD, extra-clearance and undersize options are not interchangeable; if the crankshaft has been ground or machined, confirm its finished journal size before ordering.
Should bearing clearances be checked during assembly?
Yes. Performance engine bearings should be measured during trial assembly rather than installed on the assumption that a nominal bearing size will produce the required oil clearance. Your engine builder should measure the journals and assembled clearances for the intended application.
Are these main bearings suitable for a performance RB30 build?
ACL Race Series bearings are intended for performance engine applications. Suitability for a particular power level or use depends on crankshaft condition, machining, oil clearance, lubrication, engine tune and the overall build specification.
What should I check before installing RB30 main bearings?
Check the crankshaft journals for size, taper, roundness and surface condition, confirm the bearing shells and housing are clean, and measure assembled oil clearance. Final clearances and assembly procedures should be determined by the engine builder for the specific engine.
