CM 870 hard start issue

[pearce trucking]

I've just finished rebuilding my ifsm. Here's a pic of the back of it while it was off the truck. The two pulsation dampers are there. The bottom bolt on each of them just holds the pieces together. The top two bolts on each screw into the ifsm. You'd be doing the removal and installation blind, but a simple crescent wrench should remove the top two bolts. I believe the torque on them is only 84 inch pounds. Once you remove them, take off the bottom bolt and disassemble them. You need to replace the nylon ring, the two internal orings and the mating oring. It's easy and less than a hundred bucks. Get your engine registered on quickserve and you'll find the parts sheet rawze posted and also the repair manual with step by step directions and torque needed. Well worth your time, and you don't have to go out in the rain to get registered. ;-)
6,10,11,12, and 14 are the parts from Rawze ' post that you should get.
