CFHJ...I got back to the Tranny this week. I checked the endplay on the input shaft of the assembled A500 tranny. I measured the end play three times and received these three measurements with my very basic Harbor “break” dial indicator .0315” and .0279” and .030”. From the Specs I have found on the internet for the RH42 and in the ATSG manual for RE42 says 0.021 to 0.091 in. My tranny measures to the the low side of spec. Do you agree with the spec and the measurement method?
