Rebuild kits for super m.

Postby Jason.fuller » Mon Mar 19, 2018 7:40 pm

Hello thank you for letting me be here. I’ll cut to the chase. Farmall super M engine is siezed. What do I need to do to free it? How much is an engine rebuild kit? Where do I get one? What all comes in it? Do I need,, will I need specialized tools? How long does it take to rebuild? Nit looking to repaint just get it working again cause I’m sure the paint color or condition isn’t going to get the fields worked. Where do I find free or copies of manuals to guide me? I have lots of questions. Thank you.

Opinion. Based upon the questions asked, you have little or no experience in engine rebuilding. My opinion, you will need to hire out the work to a machine shop or mechanic.

You will need specialized and frequently expensive tools/equipment. Guessing again, a lot cheaper to purchase a running/working condition tractor than starting from scratch to rebuild the engine.
I have an excuse. CRS.

To free it, pull the head and the oil pan, unbolt the connecting rods from the crank, remove crank and try to drive the pistons out using a piece of wood and a hammer.
A quick search of an engine kit without bearings is close to $600 ... s_3665.htm
Like Eugene said, you probably need a machine shop not only to check the head etc. but to do a valve job. You can tie up $1,000-$1,500 in an engine super fast.

First of all welcome to the site
it is possible to free up the engine dependin g on how it was stored prior to you getting it [in a shead,out side,in the bush for 10 years, ect.]
I did an oliver 1650 a few years ago that set out in the bush for 10 years [froze up tight]
found #2 exaust valve open and the piston stuck bad
with a little work[and a lot of prayer]we got it loose and was able to get it started
#2 ran 15 pounds lower than the other 5 cylinders,,its not a raceing engine so that was fine
still running great to this day

Many people tear down tractors and sell the parts, running tractors mean nothing, they will still be broken down for the parts. You might buy a running engine a lot cheaper than rebuilding yours. I have to go with Mike and ask why is it seized? A meltdown with a lack of oil or water? Or just something you got that's been sitting a long time? if exhaust hasn't been open to the elements, and the engine hasn't been full of water many times they can be persuaded to run again with time and soaking with various oils inside the cylinders.

My local craigslist has a seller that has about 15 used engines listed for various tractors.

better to have it and not need it than to need it and not have it...( YES this includes CUBS! )

If you really intend to do it yourself, an M has dry sleeves that are press fit and require either a custom made or factory puller to get them out. They can be put in by freezing them over night and popping them in quick, it takes 2 people, one to drop the sleeves in place, and one ready with a block of wood and hammer to drive ti down quick. You only get one chance. If it doesn't go down all the way it usually does not survive being pulled out to try again.

Do not overlook the possibility that it could be stuck due to a stuck valve.
If you are not part of the solution,
you are part of the problem!!!
