WD-45 Engine, several questions

I am not an "orange" man but agreed to help a friend get his WD-45 running. Pulled the head because compression was 70 psi on the back 2 cyls. The valves are worn so badly that I believe 2 of them were staying open due to lack of clearance. This was made worse by the fact that the oil line for the tappets was evidently left out by the last person in there. I've got a few questions:

1)The valve rotators on 2 valves were broken & part of the tiny ball bearings & springs are missing. Is this a common problem?

2)I believe the cam is directly gear-driven. Is this true? (This would rule out a timing chain problem.)

3)What is the proper valve lash & head bolt torque?

4)I can get gaskets at my local Car-Quest store. Where can I buy the valve spring rotaters & the oil line? (Reliable salvage yards)

I truly appreciate any help you can offer.

Thanks,

Mark

Try to support an AGCO dealer whenever you can. Also one of my manuals made a statement that some blocks did not have the head bolts holes taped deep enough to provide a good head gasket compression. I don't have my manual here but I think if you put in all of the head bolts until they bottom out it may be obvious if they are deep enough. If a bolt looks like it is close to being at the same height as the head and head gasket just tap the hole another thread. Maybe someone can jump in with the required dimension between the block surface and the lower surface of the head bolts.

Cam is gear driven, behind the front engine cover. For the oil line, either check another engine or a manual for the pattern- could easily bend a small copper tube to match what you need. As far as torque, I think the small bolts are 35 or 40, large bolts are 70 lbs. It's in the I&T manual, but mine's in the shop. And how you torque those bolts under the water manifold is beyond me. I just use a combo wrench and compare the pull to the torqued ones.

This is a perfect example of why I keep harping about buying the manual. So many times on this board there are conflicting answers to a question. Memory does not always serve correct. Worked on a WD engine tonight in the shop, so checked the manual for specs. Told you the wrong thing- small bolts on the head should be torqued to 25 lbs., not 35-40. Also- valve lash for intake and exhaust is .012-hot.

Thanks for the info JMS/MN. I too am an advocate for parts/service manuals. I have them for all my equipment but I'm not going to buy one for something I don't own. The owner is on a limited budget & I'm trying to help out.

I still need a source for parts. Can you still buy new stuff from Agco? I don't even know where the nearest dealer would be.

The AGCO website has a dealer locator. Try www.agco.com, might be right! A lot of parts are still available there, sometimes needs to be ordered- depends on the dealer's history. Old AC dealers are more likely to keep some AC on hand. I just got cylinder o-rings (in stock) and had to order piston rings.
