Re: Roller cam bearings
Babbitt is the only way to go.
Roller bearings, when turning the camshaft on the engine stand, the camshaft feels drag free and it turns easily. However, during engine operation and load, there is more drag while turning. When using high spring pressures, the loading may cause the needle bearings to fail. |
