MF 65 diesel industrial head gasket replacement

Good evening everyone,

I finally had time to pull the MF 65 with the Perkins 4.203 into the shop and tear into it.

For those of you who may not have seen my previous post: I purchased this tractor from an older gentleman who had bought it having been told it needed a new water pump. He replaced the water pump, but misrouted the lower radiator hose into the fan belt. Since it is such a pain to get to with the loader on, he gave up and sold it to me. When I installed the new lower hose and started filling the radiator, water started running out of the exhaust.

Long story short, I have the loader off, and everything stripped down to the head. I removed all 23 of the head bolt nuts, and the rocker arm assembly. Injectors and manifolds are removed as well as the water pump. I have tried raising the head off the engine using an engine hoist, however it will not budge and the hoist picks the entire front end off the ground.

Does anyone have any ideas as to why the head is on so tight, or any tips or tricks to remove it without damaging anything. I’m currently at a loss as to what to try, so any suggestions will be greatly appreciated.

Thank you,
Brandon

I just finished a head on an Oliver. Had trouble getting the head off. I'd actually missed 2 bolts. They looked like studs with a bit but we're head bolts. Just double check you got them all. Still had to tap a bit while lifting but not too bad.

When I worked at a dealer we had one that would not budge, I was the junior mechanic, and suggested turning the engine with the starter and the shop foreman gave me the royal chewing. For some reason I do not understand. I had done this but never knew of anyone using this method.I have wondered why I got the royal butt chewing. I know it works. Why not do this?

Had the same problem with my AD4-203 about 33 years ago. Long story short, I was able to remove 22 of the studs, some with difficulty. The one at the left back corner would NOT come out. We could swing the head from side to side and the stud was moving with it. I wound up tapping a large screwdriver in between the head and block as my helper swung the head back and forth. It finally came off. That stud was rusted tight to the head.
