After the rash of KDP causulties it quickly became a top priority to do this project. Another TDR member and I combined forces and did them both today. Both trucks are 97s mine had not moved and the other one was out 1/8" and couldnt be driven back in. We tabbed them and reassembled with no trouble. Both trucks had the bolt that the tab goes under were not loose but wernt as tight as they should be, maybe 5-10 lbs torque. A hint for those who may try it, the crank seal installs from inside the cover but can be done from outside. We read the shop manual after the fact DUH. Cummins instructions in seal kit show it going in from outside shop manual from inside, either works.
