WD45 Head Bolt Washers?

Folks-

I just took the head off my WD45. Should the head bolts have washers on them? They don't right now, but I noticed some wear between the bolt head and the cylinder head. Is that a problem?

While I have the head off, what else should I be looking for? What should I look for on the bottom of the head? Worn valves, etc.

What about the bores? How much of a step is too much at the top of the piston travel? Should I see and cross-hatch on the bore?

Any tricks to putting it all back together and not having any leaks?

Thanks for the help.

Nate

Another Allis quirk that I ran into on Wd 45's. Although Allis doesn't officially fess up to it, they didn't provide one more thread than necessary in the block for the studs but buried deep in the troubleshooting section of their manual they tell you to clean the holes and give them another one or two threads. Oil, rust or other debris can build up in the bottoms of the holes and if not cleaned will cause the head bolt to torque out but not seal the head to the block. Leads to head gasket failures, water in the combustion chambers and all kinds of other stuff that will result in alot of bad language. So bottom line, make sure the holes are clean and give them another thread or two, especially if you've had the head planed. Hope this helps. Bill

Nate, when installing head bolts, if there is oil in the hole it can cause a hydralic lock and prevent the bolts from being properly torqued. Clean the holes out and lub the bolt threads with engine oil. I take my heads to a machine shop that has expertise in valves, and get the face resurfaced also. Saves a lot of time and I never had to redo a job. alvinnms

Correction- Just now looking at a Case shop manual, shows to use new washers on the head bolts when rebuilding. You really need a repair manual. Click on tractor manuals, top left side of this page. alvinnms

I can't remember a washer on a head bolt. The wear you are looking at, was machined there for a purpose, so put them back like they were. If you do anything, use new head bolts, because the old ones are streched and tired. alvinnms
