JAKE ADJUSTMENT ON ISX

[Minich Truck Repair]

Thanks for the reply, after 2 heads and having the same results the place we bought them through decided to send one of there cummins certified guys to come look at it. He went through and checked all the gears on the front said they were all good, put the wedges in and pinned it to time the cams went through on the adjustments and got the intake and exhaust valves adjusted just like we did. Got to the jakes and had the same problem as us on them, he tried a few different things and couldn't get them to adjust. He had us pull the head off while he made a few phone calls, he wanted to check the liners to make sure they were within spec for clearance and not sticking up to far from the block and everything checked out. His recommendation was to send the head back and get an OE cummins head, said it has to be in the machining of the head. New cummins head will be here tomorrow.

Again thanks for all the input
