Camshaft torque specs

[IHdieselfan]

Does anyone know the torque spec on the allen head bolt that holds the cam gear on. and the two retainer bolts.

15 ft-lb on allen. No special torque listed for the other two, just standard torque for the bolt size. 5/16 is 14 ft-lb, 3/8 is 24 ft-lb.

f you are installing a cam gear please warm it up to no more than 250 degrees. That will grow it enough to fit easily. Same with all the other parts up that end of the cam. If you have the cam gear with the clean face thats the good gear. The gear with the drilled and tapped 2 holes is the unbalanced gear and it causes vibration at idle.

Extra points....if you can freeze cam whilst heating parts...shoukd freakin near fall together.

Good idea Al. When I froze parts while working in the huge machine shop we used liquid nitrogen. That stuff is 280 degrees below zero. Drop in what you want to shrink. Wait till it stops boiling. Then remove by the wire you hopefully attached to the piece and for sure wear safety equipment. That would be a FULL face shield and some hand protection. I liked using Tillman welding gloves. Liquid nitrogen can burn as bad as any hot material can.

They press on quite easy without heating/freezing with a standard press.....at least mine did.

They all do, a little motor oil and slips on.
Please do not hammer them on, seen it done, not pretty.

Any hammering on of the gear is ugly to watch.
