I have seen lots of threads about engine repair and what to do. I hope the info I provide will help anyone who may be doing the same.
I have a M35A2 with the hercules multifuel. It has 59,000 miles and 2200 hours. After I made my 1100 mile trip from Michigan to Nebraska, she ran fine. The first week in Nebraska, the bolt broke on the tension bar for the alt and the belts. My truck overheated because the water pump was not turning fast enough due to loose belts. This caused my head gaskets to fail. She got so hot that it bent a push rod and melted a piston which ended up breaking apart. So over the past few weeks I have torn the motor apart and removed the heads. It was fairly easy however alot of improvising was needed with tools and leverage. When I removed the bad piston and sleeve, I went from underneath. I removed the oil pan, disconnected the rod from the crank, removed grill guard and pulled out the radiator, removed fan blade, used a 3/4 drive breaker bar and socket to turn the crank pulley. This allowed me to more easil remove the piston. I dont recommend pounding it out, I used a long bar with a clean rag on the end of it and my floor jack with concrete block under it and pressed it out. I did get lucky because the sleeve came out with it due to all the melted metal in it, it would not allow the piston to come out. So far I have spent about nine hours do get this far. No air or power tools just the manual stuff. I took at least sixty pictures as I went. All I have to do is get replacement parts which the cheapest I have found was Tnj Murray's. I will take more pics as I go. If anyone has any questions about this topic, just reply or send pm and I will do my best to help.

I can tell you that it will be a bit of time. Anyway, one thing you want to do is see if your block is marked "TD" on the passenger side just a little forward of the data tag....it will be raised letters that are cast into the block. This will come in handy latter (for which torque specs to use) also on here is a member (m-35tom) to get the NEW style head gaskets......also a very great guy to deal with and very reasonable..........anyway, if you have any questions just give me a shout, more than happy to help with your build.
my homemade engine stand "frame"
and now it is in the truck, so I'll just have to get a pic of that.........it's SOOOO PURTY!!
