Engine/Transmission (1998.5 - 2002) Need PN of 2002 exhaust manifold SS dogbone bolt keeper

[rweis]

Need part # for the stainless steel dog bone exhaust manifold bolt keepers on a 2002.



I tried Drake Lock nuts and they are not holding without periodic (6 months?) retorqueing.



I put a ATS manifold on and then Key Belvilles and Drake Locknuts. The Drakes are not staying torqued permanently. I will change the Drakes to regular nuts, and torque them to appropriately. I do not want to trust Locktite blue. I need something that will KEEP the manifold bolts from turning period. Manifold should be in place permanently.



The dog bone manifold bolt keepers that DC had on it I think will work with any nut approximately the same size. Just need the part number so I can order them from Peterbilt.



Thanks

lock washers special

I used anti vibration washers from REID tool. they are two serated washers that go together. On two ATS equiped trucks no problems.

I thought I had the nut vibration whipped as well with the Drake lock nuts. Nope, over time, after checking them 3 times over a period of 9 months two of the belville washer packages have been dumped off the studs of #1 cylinder (both top stud and bottom stud).



I think the stainless dog bone will positively stop the loosening permanently. At least that is the route I am going to try next.
