We are building a 2.1 /4 cyl. motor and have sent the rotating parts for balancing. Prior to I had the flywheel resurfaced at NAPA. Unknowing they removed the dowel pins that locate the pressure plate. I got all the parts to an old friend for balancing (he owed me a favor) and he turned the rotating parts around for me. He balanced the crank by itself, then added the fan and flywheel, but NOT the pressure plate.
Question: The factory book states the pressure plate should be aligned with the flywheel with the mating marks. The flywheel was not mounted to the flywheel due to the lack of dowel pins and is the pressure plate balanced by itself or as part of the assembly? |

Should have been done together, but get a KEP stage 1 pressure plate, last few jobs I've done with KEP PP's my balance guy said they were spot on.

Yes, when the complete rotating assembly is spun up, there are no questions. I will look for a KEP unit. Thanks |
