If you don't have a dial indicator, a simple method is to measure it with feeler guages at both extremes of movement against the case. If you want to get fancy you can make a "reference" with a bolt, 3 nuts, and a small tab bolted to the motor mount. Secondly, you are probably correct in assuming that it is still ok without checking as the shims and the bearing face should return you to the same place. The question looms: is it worth messing up such an important tolerance when it is so easy to check and know for sure. Think of it this way,. racing engine builders check this measurement probably 4 times on a build. Besides, you probably don't want to do a complete case split rebuild just because the shims didn't go back in right. I"m not trying to preach, I just know how many times I've had to do things over because I thought I had already checked it once. Kind of like the cam gear fit in my '81 Westy that has a whine now. Should have checked twice.... Good Luck Mark Rokus |
