I've been working on a long neglected HD3 dozer, things where going well until I discovered the head was cracked between 3 and 4 exhaust valves. This allowed the inserts to fall out and then be hammered into the pistons. I would imagine this head is now junk, yes?

Thanks! I will look into both of those. In the meantime, I have a model 400 winch I would like to install. Does anyone have an exploded parts diagram they could post (or sell)? I know I am missing the intermediate drive shaft plus who knows what else.

Update. I got my head back from the shop (Chapin), got it mostly back together and torqued to the block. When I realized that someone had previously installed the valve rotaters on the exhaust valves (they should be on the intakes). I was careful to put it back together the way it came apart and didnt notice until too late. Will this be a problem if not corrected or should I just not worry about it?
