Bearing Specifications Are Important
Send REV6 your block, rod, and crank numbers when ordering. Our team can use those numbers to mark the required bearing specifications for easier installation.
Check the numbers carefully before sending them to us. Correct bearing selection is an important part of assembling the bottom end with the proper clearances.
Inspect the Bottom End During Teardown
Check the crankshaft, connecting rods, balance shaft, and bearing surfaces for wear or damage. Also inspect the timing and oil pump drive components. Address any damaged parts before installing the new bearings and chains.
Keep Bearing Surfaces Clean
Cleanliness matters during bearing installation. Keep the journals, bearing surfaces, and oil passages free of debris during assembly. Then verify the required clearances and follow the correct engine specifications before final assembly.
