I recently purchased a MF 35 and lost compression while cutting a field. I've removed the cylinder head and found the gasket between #1 and #2 cylinder broken, which explains the loss of compression and severe buring of oil while limping home. First, where can I get a head gasket for this model, preferably without buying an entire overhaul kit? Second, should I tear down any further since I have the head already removed? Should I check the piston rings, and if so, how much more difficult is it? I've never torn down and a tractor engine before, so I'm learning as I go. Thanks for any help you can give me!!!

Dan, don't take this as critical. By reading your questions and your responses, I highly recommend that you DO NOT remove the oil pan to check rods/mains without some high quality help. You could ruin engine in a heartbeat. Have the head serviced at a good machine shop, tell them to remove any warpage, test for cracks, etc. Purchase a quality head gasket at MF dealer. Clean top of block until spotless. Buy yourself 3 real MF brand manuals: 1 Operators Manual, 2 Repair Manual, 3 Parts Manual. Follow Repair Manual procedures to the letter for the tightening and re-tightening with a quality torque wrench - - don't guess how tight. Good luck, Tom

To check piston wear just take your fingers and move piston back and forth while at top of cylinder to see how muck slop there is and you can always drop oil pan and remove a rod and main bearing to see what kind of shape there are in before you need to totaly tear it down and check with any AGCO dealer or napa store they should be able to order what you need and while you got head off have it checked and make sure it is not warped .

Thanks for the inputs!!! I'll check the one piston that is at the top for slop. Is there an easy way to turn the the engine over slowly to get the other pistons to top position to check those also? Before I drop the oil pan, how difficult is removing the main bearing and rod? Will that change any timing that will require the engine to be retimed?
I'll get the head checked for warping. I'm not familiar with AGCO? What does that stand for, is it a national store?
I really appreciate the help!!!

Dan AGCo is a corp that has bought up all massey white and allis chalmers companys and several others so any of them can order your needed parts now , and to get other pistons up just bump starter or put a socket on the nut on end of crankshaft pully ,as far as removing rods and main there is what they call a cap like a half moon you will see them if you remove oil pan when looking at crank usually just 2 bolts hold each cap on and then you can see how much wear bearing has bearing is inside each cap if good make sure you put back on the way it come off important and tourque caps back to correct values

Also, was there a lot of blow by before the head gasket went? Was she using any oil? Was the power off a little?

If the cylinder walls look OK and the answers to the above are not yes it probably is OK.

I didn't see/hear any blow by. The power started to be reduced, and within 5 minutes, I didn't have enough compression to run the brushhog. I had to keep her in 1st gear the half mile home, otherwise she stalled. The cylinder walls look good, but I can only check two of the cylinders walls since those pistons are down. Is there an easy way to check the third cylinder without having to retime everything? Also, any recommendations on getting a replacement gasket? Thanks for the inputs and help. It's a little nerve racking not having done this before. I appreciate the help!

Hi Dan,

Did you feel the engine was ok before the headgasket were blown ? Do you have a large ridge at the upper end of the cylinders ? This will tell you if the engine is a lot worn or not.

One important note, when you have put on a new headgasket, start the engine, run it warm, then open the valve cover again, and retighten the head nuts. If not, the new headgasket will likely blow again in the close future.

So, it is not as a regular car engine when no re-torqueing is necessary.

By the way, is it a 3 cyl or 4 cyl. engine ? And is it diesel or gas ?


Bill

Thanks for the information Bill. The MF35 is a 3 cylinder diesel. The engine appeared fine before I lost power, and I don't see any ridge on the cylinders. I didn't know about the re-torquing. How long should I let the engine run before tearing back down to retighten? Literally, just 5-10 minutes to get it warm, or let it run for a few hours with little load?

Thanks again for the help!!!
Dan
