Case 188d Rebuild

[Pete14]

Hey guys Im new to this forum thing but i am rebuilding a case 188d out of a 1967 580 CK. Anyway i took the engine to a machine shop and the guy asked what the clearance from the valve to deck height is

Valve recession or protrusion for 188 d is .005 above to .015 below deck.

AERA spec manual gives these numbers , surprised the shop doesn't have one.

This particular Shop doesn't typically do these engines so he asked me to find that info. All the other info I needed was in the manual I had that he needed. That was the only thing missing. Thanks for the info I will let them know.

I would keep the valve protrusion at .0 to .005 above. This will aid in easier cold weather starting and cleaner running under load.
