Retorque.

Better do it. The MF dealer I worked for years ago we would always do a hot retorque on both Continental gas and Perkins diesel engines.

Ok, so pull the rocker assy?

Yup, Unless you have the tool that we had that could do the retorque without removing it.

That won't work, we had a U shaped box end for the torque wrench.

Dieseltech, can yiu explain? i have to use the crowfoot on the head bolts that are on the spark plug side anyway.

First- retorque, properly. As to crows foot: first- bite on 2 flats ain't cool. #2- you would need to Calculate actual torque due to variable offset length. Not cool, and your tractor will peg you as an egghead, sissy, or both and fail. And you will mess up. Feel lucky?- do one retorque and not due 20 hour #2 retorque. Your call.

The spark plug side is not critical. We had a horse shoe type wrench that would go under the arm shaft on Continental engines. Still had to pull the shaft on Perkins engines though.
