Farmall M removing pully's in the front

John Lundberg · Aug 16, 2011

I was wondering if someone would have a picture to show how to remove the pully's in the front of a Farmall M. I'm trying to get to the Timing gear.

Thanks,
John

John - First remove the big nut that holds the pulley on (it's a 2-1/2" hex). Then simply pull the pulley of the front of the crank.

Usually the pulley will slide off by hand - no puller required. However it's wise to have a suitable gear puller on hand just in case(!)

Bob,
How do I dissconnect the hand crank starter in front?

Generally the front of the tractor is removed to access the gears/pulley etc. IIRC the pulley will not come off far enough to clear the shaft W/O hitting the lower bolster. Getting the front off starts with removing the steering shaft from the gear box. Jim

John - I just sorta assumed you already had the front end off. (Like Jim mentions you need to remove the front end to get at the pulley and timing gears....)

Anyway you'll need to remove the hood/grille sheet metal, disconnect the steering shaft and the radiator brace rod. Then drain the cooling system and disconnect the radiator hoses.

Next jack/crib the tractor until the front wheels are off the ground. Then unbolt the front bolster at the side rails and using an engine hoist or loader, slide the entire front end ahead and away from the tractor.

You'll now have open access to the front of the engine.

can you remove the front wheels and the bolster together and just roll in out with the tractor jacked up?

john , it can be done that way if you have a hoist or forklift to handle it. the bolster with the wheels on is darn heavy, and real tippy. if you are careful and take your time, you can remove the whole front works, radiator and all. however, if it gets away on you, you will be buying some spendy parts. you also need to remove the crank start pin from the crankshaft , if it is still in there. start spraying it up now with penetrating oil so it gets a good soaking,. there is a small set screw that holds the pin in, loosen it up and drive the pin out.

If supported in all four directions, left and right, forward and back, yes. It is tall heavy, and rolls crooked. Support the engine under the clutch housing where it is strong and not on a tin plate, or the oil pan. The belly pump is a good place if so equipped. Jim

Yes John!

I've done it using both a front loader and an engine hoist.

DON'T try to manhandle the front end! As others point out it's extremely top-heavy and is downright dangerous to handle unless suspended from above.
