YM 2200 Eng Rebuild

[jimsxl]

Hi All, I'm doing a complete overhaul on my YM200. I have the engine cleaned , ready for new cylinders,my question is ,the liners came with two o-rings for the bottom of the cylinders,but what seals the top? Should I use a sealer or does the headgasket take care of sealing the top of the cyl. liner? Should I use any kind of sealer on the headgasket? I also need to know the torque specs.for the rod,main bearings,and head.The rod bearings broke @ 45lbs, the main bearings broke@125lbs,however I think that would be too much.This is my first deisel eng.rebuild,so I realy need some help. You guy's are great,and I thank you. Jim

My manual says to use an oil based paint on orings . However I used a thin film of high temp silicone sealant instead and have had no issues. I also put a thin film of sealant on top 1/4 inch of sleeve and seated them. Some of the sealant will squeeze out---- just wipe off. I used old sleeve on top of new sleeve and pounded until seated properly.

Put sleeves in freezer overnite to help with installation. Make sure the sleeves are seated correctly there is a tolarace for the height they should protrude above deck. Do not know what yours is b/c I do not have a manual for it.

If its the same engine that is in a JD 850 (3T80) or JD 950 (3T89) I have that info. Do not rely on a manual that does not have your specific engine addressed.

What engine do you have?

If I were rebuilding my engine, I would replace all the old main cap bolts as well as all the rod cap bolts with new ones. These bolts are under a lot of stress.Replacing the old bolts with new ones is money well spent & cheap insurance

kenmac, if you had a ym2200 you ,you would be happy to find the basic parts.Do you know of a source for the parts you suggest?How about the torque specs? thanks Jim

Danny Thanks for your interest,I have the 2tr22

I don't think you will find anyone with the torque specs for the 2TR22, this is what we use.

Head 130lbs + or - 3.6lbs
Rods 33lbs - 36lbs
Mains 22lbs - 29lbs

Thanks again Danny, Jim

I have no idea about parts for your tractor. Danny, hoye ??

Danny, those torque values for the head&rod bolts sound about right,but 22-29lbs.for the mains seems way too little.Did you forget to add 100 lbs. to those numbers? Jim
