Yanmar 2210b head gasket repair!

[ddwyork]

Hello fellow Yanmar owners! This is my first post here and im a newbie to tractors as well so here it goes. I purchased a
yanmar 2210b not to long ago from a guy who's father had owned it and recently passed so he didn't know a whole lot about it but thought it needed a new water pump. Well after further inspection there was water coming out of the weep hole so i've ordered a new water pump, hoses, and gaskets. I changed the oil in it this weekend and it was black no signs of water or milky substances. It wasn't until I checked the radiator out when after a cold start it would build pressure quick and foam out, the temp gauge never went hot but im not sure it works though either. My question how bad is it to change the head gasket assuming it is blown. I know that service manuals are hard to come by and Ive never really worked on a tractor before. I am mechanically inclined though so hopefully it won't be so bad. Anyone ever experienced changing one out? Pointers, Tips? Something? I really like this tractor it starts up fine and runs great, I don't want to mess it up. Thanks.

Your service manual is available at Hoye Tractor for about $50 and head gasket is about $45. I've never done a Yanmar but it's pretty basic on all small diesels. Lots of online references to replacing Yanmar head gaskets and from what I've read, head should be torqued to 130ft/lbs. Start in the middle and work out, torque the head bolts in steps of 40, 65, 90 and final torque of 130 ft/lbs.

The Yanmar forum below is a great place for Yanmar specific questions.

If the tractor was run hot, You may want to take the head to a machine shop and make sure it's true (flat) B-4 re installing. You don't want to go through all that work, only to have another blown gasket because the head is warped
