MackMack613 13 Posted December 8, 2017 just curious to know why the input shaft sticks out at least 8 inches forward of the of the round casing. This came out of a 93 DM690, supposedly has 50-60k original miles. I have a picture of but it will not load. Thanks for any help Share this post Link to post Share on other sites

MackMack613 13 Posted December 10, 2017 Update: I did find out that the long input shaft was indeed correct for the truck it came out of. It did have a flywheel mounted PTO. Share this post Link to post Share on other sites

41chevy 9,046 Posted December 10, 2017 Yes about an hour or so if you've done one before. I haven't done one in years but it all comes out from the front. Input shaft cover, a snap ring, bearing and second snap ring as I recall. I think there was also a bearing on the main shaft the Input shaft goes on. Need a seal and gasket for the cover and lock tight the bolts. Personally for the hour labor I would let a tranny shop do it while you wait. Share this post Link to post Share on other sites
