Hello fist ? I twisted off one of the center manifold bolts , both center bolts are seized
to the manifold any suggestions?? Second ?? the oil filter housing is on opposite sides of
the block, can this be just switched side to side or do I need to do some thing under the
oil pan?? 3 rd ?? some say I can use the oil pan from the combine , a friend used the
combine pan on his 1850 , I will know more when I get the engine out of the combine ,
Thanks Bryan
 
You have to use the tractor front engine cover because the motor mount slides around it. Because you used that front cover, you need the tractor oil pan. The tube on the tractor oil pump has to be used to get the oil to the other side. You might need the whole pump, I don't remember. You'll need to put a pipe plug and soft plug in where the combine filter base was. You need the tractor tappet cover, rear side cover, water pump, manifolds, injector pump linkage and injector lines. There might be more, but it's been a few years since I've done one and the memory is fading. Pretty much just plan to strip the combine engine down to just the block, crank and head and replacing everything on it with parts from the tractor engine.
 
If any of the bolt is sticking out from the head, Heat them up, pour some cold water on them while still hot. That may help. We used to loosen brake bleeders that way. But the way I have had the best luck is to slide a not over the broken piece and weld it using a wire welder. Easy to control the welding process that way. I have done the same thing when broke off flush with the head. Using a wire welder and little short bursts try to get the weld build up to stand out from the head surface. Then place a nut over it and weld it to the weld build up. The heat generated welding helps a great deal.
 
Arnie, have you ever tried a flat washer then a nut? I've had fantastic luck welding a flat washer to the broken bolt then welding a nut to the washer. You can weld around the outside of the nut to get more surface.
 
No I haven't. I'll remember to try that. Before I got the wire welder I used to that with 1/16 rod and a stick welder lying on my back under a Chevy pickup trying to keep from having to take the exhaust manifolds off. I don't do that no more. Too old. Thanks for the tip.
