Cam degree question

Set up a dial indicator on top of the piston. Roll it to the top and zero out the dial. Have the wheel on with a pointer somewhere around where 0 should be

Turn crank counter clockwise, then go back clockwise and stop at .050 short of top, note where pointer is on wheel.

Turn crank counter clockwise and bring it up to the same .050 level, note where pointer is. TDC is right in the middle of those two noted points.

DO NOT roll it over the top and measure pulling the piston down for the second reading. You can roll it over the top and run it down the hole .100, then come back up. Always measure with the arm approaching TDC in each direction.

Once you have it set, do the same thing to verify TDC. Takes a couple minutes and simple.


Extensions for the dial indicator are cheap and available on amazon/internet
