How not to install crank seals!

[Paychk]

I R/2 my clutch this weekend & thought I covered all the bases. Boy was I wrong! When I pulled the flywheel to change the seal, this is what I found. The previous mechanic left the “seal installation tool” in behind the flywheel. This chewed up the seal holder. When I got the tool removed; I found something even stranger, another ring of some kind between the tool & the seal. This extra ring isn’t steel, maybe some type of aluminum. Anyway I pulled the seal holder off my spare engine and proceeded with the clutch install. The rest was down hill.



Moral of this story if you haven’t wrench on a Cummins B, get some type of factory manual be it Chrysler or Cummins and use it! Or just come in here and search for your answer or post a Q!

Lucky you had a spare seal holder. When i did my truck the seal was loose,i hooked it with my fingernail and pulled it out! I replaced it with a multi-ribbed stemco type seal. Worked good so far.
