Hello, I am in the process rebuilding a 550 oliver. I had the block hot tanked at a local machine shop and then ordered the cyl kits,brgings, and gasket set. I have installed the kits and pistons. I noticed that the pistons actually rise above the block about .008. Is this normal. I am in question if they are the correct kits because at this point the machine shop is in question what I really have, nearly all of the gaskets in the kit are wrong. All I can find is the casting # on the engine and the head. I thought that the tractor was a 1963 but I found a date casted in the head and the stamped in the block of 1967. Is there anyone out there that can tell me what I have based on the casting # so that I can get the correct parts? In addition the tag with the serial # is also missing so I can not identify it that way either. Thanks in advance | ||

The pistons and sleeves should all be interchangeable, no matter what year your 550 is. My 1957 Super 55 has 550 pistons and sleeves in it, if that tells you anything. It sounds like you have the wrong kit. Did you order for an Oliver or Waukesha engine. While this engine is technically a Waukesha, it is built to Oliver's specs, so there will be some differences, and this might be the problem. Post that casting number, at least that way we can verify if it is an Oliver Waukesha engine. Where did you order the kit from? | ||

Guess I cannot anser for sure what the shop ordered for. The casting #'s are as follows. The block #'s are 180220L, 159002A, 11216. The head # is 180662 with date casted in of12-23-66. Thanks again for any help you can give Greg | ||

That's definitely the Oliver engine. The 159 002A number is the part number for the bare block. It was cast on November 21, 1966. I still haven't been able to find a spec for how far up the piston should come. I'm sure the thickness of the head gasket is more than .008, but I just don't remember ever seeing a piston that stuck up past the top of the sleeve in any engine I worked on. But it's also been a few years since I have had one apart. Schwiebert, what do you know about this? | ||

If you happen to have an Oliver repair manual on page 2-22 it says that the Sleeve projection above the crankcase is .001" to .004". However, as Chiss has pointed out the gasket is thicker than that. The Oliver gasket is listed at .040-.05 inch of asbestosm pressed between .012 steel plate and a .012 copper plate. Upon futher reading the manual I found the following, Sleeve projection should be .001 to .004 inch above the crankcase surface. If greater, remove the sleeve and clean out the upper bore shoulder in the crankcase. If one side is higher than another, remove the sleeve and straighten out the packing rings and lubricate again. | ||

Greg is talking about piston protrusion not sleeve protrusion. He is fine with the 0.008 height. I hope you do not have an asbestos head gasket, well they do seal better. All the American gasket manufactures went away from that 10 years ago. Lets us American live longer so we can pay taxes longer. I don't know if paying taxes in Canada is the popular item either. how are you. | ||

John, I was just quoting the old manual directly. The only place I have asbestos around here is in my classroom on the ceiling. The way they deal with it is they leave it alone. I'm doing fine. Last time I messaged you I was hoping to pick up that 2-26 potato digger. I wasn't able to talk the fellow into parting with it, but I think I did talk him into going to the tractor show in Lynden, Washington this year. I look forward to that one every year. I may have my tractor ready by that time. Keep up the good work in the HPOCA magazine. |
