What are the steps to remove the M&W hand clutch and can i use 400 gear and brakes to put on my super m? Any one have diagrams of this would be appreciated or directions. HOW long should it take to remove the m&w? Thanks JM
 
I asked about this a few weeks ago and IIRC the whole thing can be performed without taking the deck cover off the tractor on a Super M.

I've got an M&W clutch on my Super M, myself. It sorta works sometimes. I took the cover off and a steel ball came out. Dunno if that's part of the over-center mechanism or if it's part of a disintegrating ball bearing.

There is a diagram if you go to modern view and search for "Super M M&W clutch diagram." Unfortunately, it doesn't have a parts list, and when you get to the outside end of the blowup, all you can see are several small nondescript parts with numbers pointing to them. I can't tell if one of them is a steel ball or not.
 
You can buy reprint manuals. The clutch is a pretty simple device.

You can download from this site.

Vollbracht and Nebraska Kirk have parts
 
It can be removed without taking top of transmission off. 400 parts will work. You will need the outer brake cover, inner brake(where seal is), expanders, bull pinion shaft, and the braket on the end of the brake shaft.
 
Don't forget the bull pinion housing will NOT come out unless bull gear is removed,and the bull pinion housing is different on the M&W clutch equipped Farmalls.
 
Not sure if I remember every step, but should be close. Remove the big cover, remove the clutch plates and drive shaft. Remove a snap ring holding the clutch brake drum on the splined bull pinion shaft. 6 special bolts hold the plate cover was atached to. After the plate is removed pull the adapter piece that takes the place of the IH bull pinion retainer and then the M&W bull pinion. After the clutch plates are out of the drum you may be able to remove the special bolts through the holes in the drum and pull all out at the same time. Think I did that once but can't remember for sure. No need to remove the differential and bull pinion bearing support housing. Use regular size bolts to replace the special bolts retaining the housing. 400 will have all the parts needed to put back like IH.
Good time to put a new seal in the bull pinion bearing retainer and maybe a O ring on it if needed.
 
I have the big shaft out with the inner splines and also the 5 allen bolts off the adapter plate. but cannot get the adapter plate off and the brake drum how do i get this off. Is there another gear i need to get out behind adapter plate also??

Did you pull the axle and drop the bull gear as mentioned above?
 
i cant get the brake drum off or adapter plate off i do have the 5 allen bolts out. How do i get it off, is the big o ring holding it up. I read just now that i may have to slide axles out and drop bull gear?? yes or no? How do i do that?
 
Sould be 6 bolts. If the adapter plate is stuck to the adapter housing it has a oring and fits tight in the housing the 6 bolts come out of. That housing needs to stay in place to the transmission housing. When the adapter plate is out of the way regular IH size bolts need to go back in the housing. When the adapter parts are out a M&W bull pinion shaft with a bearing comes out and then is replaced with a regular SM type bull pinion shaft. Other fellows are thinking about band brake M tractors when saying the axles and bull gears need to be removed. On a regular SM a plate that the inside disc brake shoe contacts holds the bull pinion and bearing in and has the shaft seal and is also a tight fit with oring. On the M&W set up the adapter plate and round part of the adapter housing hold the bull pinion and bearing in.

OOPS!. Never been into the M&W on a super, assumed it was the same..

I know it is quite a job on the regular M since I have worked on those.

I am going to put one on my M soon.

Failed to say there is a retaining ring. Maybe spiral type( cant remember for sure if thats the type) keeping the drum from sliding off the splined M&W bull pinion shaft. If you can get all the bolts removed from the adapter plate without removing the drum the shaft drum and other parts will come out together. I remember the 6 bolt holes being used to retain the big adapter plate as the same ones IH used to retain the differential carrier housing. If my memory is off maybe the five bolt holes used to mount the IH disc brake drum were used for the adapter plate if you can only find 5. Almost bet on the six though. Been a long time since I worked on a SM with one. Let us know how you make out.
 
If down to the hollow shaft going in the transmission housing, yes prying is needed.
Housing on the right in the picture goes into the transmission housing. Top side of it will be looking at you on the side of your transmission housing after the adapter parts are removed. Housing pictured on the right stays in place when clutch or brake parts are removed or installed. IH gear and shaft in the picture slides inside the housing pictured on the right. M&W shaft that takes the place of the IH gear is hollow instead of solid. Plate on the left is the IH part that holds the pinion gear and bearing in the differential. Round part sticking out with the oring on it slides in or out of the housing on the right picture pretty tight. M&W adapter piece will be inside the housing pictured on the right with a oring also. If everything else is removed the oring or the pinion bearing a tight fit in the housing will be all thats left holding things.

Great picture and info. I thought 5 bolts was all of them but i missed one and it really does make a difference when trying to remove. LOL Thanks,
