hi I wonder if someone has the torque specs on 2006 d8t cat c15 rocker shaft specs.kpz01156
I think this is what you're looking for. I hope that you discarded the old bolts and fitted new ones. The spec is "torque-to-yield" Or, let me guess, a rocker shaft bolt broke..?
hi no I changed the injector sleeve and injector o rings.but thank you very much for the help
DO NOT under any circumstances re-use the bolts that you removed. Throw them away and fit new ones. Your engine was originally built with the former bolt Part Number that had a washer under the head, although they may have been replaced at some point in time since then. You cannot use the torquing procedure in the article I posted above for the former bolts. It only applies to the new Part Number of 12-point head bolt with the integral washer in the head. 4 new bolts @ US$15 each could potentially save you from some catastrophic damage up top.
yes my bolts the are 12 point head with wsher integral.
OK, so they have been changed before at some point. Not surprising in 15 years I suppose. However those 4 bolts are still "one use and throw away" because of the way they are torqued. Reusing them is running the risk of one or more of them breaking.
