I have the timing cover off the 90 for KDP and new seal.
I found four bolts around the accesory drive(13mm head), two on cam the retainer plate (13mm head), and three in a trangular pattern around the cam area. (10mm head). Are there any others that I can get at, to tighten while I'm in there? There is also one behind the cam gear,but can't get at it.
The KDP was fine, by the way, but I put a retainer tab on it.
I got the seal from a Dodge dealer. It was in a Cummins package.It came with a guide to help instal it over the crank, My cost $32.
Thanks

I just did that about an hour ago, i put lock tight on all the bolts that i could and put it all back together.

 

I figured that I had found them all. Just wanted to check before I button it back up.
By the way. The crank seal is hard as wood. It still didn't leak. 220,000 miles.
Thanks
