mackrmodel686st Posted April 4, 2017 Share Posted April 4, 2017 I have a 1993 ch 613 mack with a 400 engine. I'm replacing the trans and noticed oil in the flywheel housing, pulled the flywheel and sure enough the rear main seal is leaking. How do i remove the old seal, I've replaced a few on the e7 engines, but was always replacing the flywheel housing also. How do i go about removing the old seal without pulling the flywheel housing off? Quote Link to comment Share on other sites More sharing options...

theakerstwo Posted April 5, 2017 Share Posted April 5, 2017 And if its got a wear ring i use a torch and heat a spot on the ring just a small amount then pry on it with a screw driver to lossen it.Just dont blow it with the torch and no more heat than a few seconds.Now you need a installer. 1 Quote glenn akers Link to comment Share on other sites More sharing options...
mackrmodel686st Posted April 5, 2017 Author Share Posted April 5, 2017 Thanks again. I know about the install tool as I said, I've done the install a few times, just never pulled one without pulling the flywheel housing. Quote Link to comment Share on other sites More sharing options...
