    Somebody will come along and tell you the exact procedure pretty soon I'm sure. Its been a couple years since I've messed with a Cummins but Line the letters up on the accessory drive with the marker on the front cover. A=cyls 1&6, B=cyls 2&5 and C=cyls 3&4. One or the other will be on TDC and adjust that cyl. Should have to just make 2 full revolutions. Also the lash measurements should be on the info tag.

    Sorry for the kinda shetchy info. Its been a while, but that there, I do remember. Only pushrod motor Ive seen in years is the MBE's.
