removing the cast center, need help

BigTone · Mar 26, 2012

I need to take the cast center off my M, can anyone walk me through how to take them off and if there are any tricks to getting them off?

thanks guys

No tricks to it. Just remove the two inner and two outer bolts that hold the wedge onto the axle, then your ready to take the hub off the axle. Keep in mind after sixty plus years the bolts might need heat to get them to turn. Good luck. Kent

Yes,Like Kennell said,

I would start with P B Blaster on the bolt threads.4 per axle wedge.2 inside,2 outside.

If they do not come easily,it might take some torch work.

SAME with the outer ring against the rims.

Be sure and clean the bolt threads up well and the threads in the wedges before re assembly. Torque all 4 bolts evenly when retightening!

Thanks guys, I figured I would have to hit it with pb blaster a couple times over a few days to start. I appreciate the help as always!

If necessary I use a 3/4 inch breaker bar with a pipe on the end. Hasn't failed yet. I also remove the rims and any weights, and support the wheel with an engine hoist -- reason for that is the hoist turned over the first time I used it with only a C wheel and rim hanging from it.

If you have done the heat and cheater bars to no effect, perhaps you can borrow a torque multiplier. The one pictured has a 50 to 1 ratio. They are not so common but 4 to 1's are and may do the job.

The yellow square tube is the slide-on torque arm and bears against something immovable like the frame of the tractor. The 1/2" ratchet works like any other. If the torque multiplier were not there, it would take a 50' breaker bar to get the same torque.

It generally does the job but I had a few 1.5" bolts at a 60 year old flood control dam that wouldn't budge.

I will add that it helps to clean out the grooves and run a file over the corners to get burrs off. Once the hub is loose, lube the whole axle. Put the big part of the hub "up" and the loose clamp half down. Tie it to your hoist and once you start to rock it the thing will slide right off.

He's right, cleaning and lube are the most important thing. I usually jack the tractor up so the tires just skid on the ground. I use a long bar and push it off sometimes if it comes hard.
