Bern Kansas | These are not hard if you are talking about the tming case over. Just pull it off and pop the seal out and put a new one in if you are sure this is what it is. I would check for cracks. But the min thing i would look at is what the call the "KILLER DOWEL PIN". Yes this is a Cummins factory srew up. This dowel pin can cause alot of problems loss of oil pressure and can run through the timing gears. Can get expensive. | |
