Hello again all!,

I have to split my 1935 orchard caterpillar 22 and remove/swap the clutch brake collar, I would like some input before I attempt this venture into the unknown,here's what I know so far; I have to remove the gas tank, the cast-iron fire-wall, throttle linkage, fuel selector linkage, oil gauge line, fenders(because they also act as engine side covers by running the full length of the tractor), hood, fuel lines, kill switch wire, and both leaf-springs. Then I put slings under both ends of the engine and block up the bell-housing, then I remove the bolts that secure/mount the engine to the bell-housing, and separate the two.

After that though I am clueless as to what I need to do to remove the collar, I "think" I need to remove the friction pads which are on a thing that looks like a spider-web, then the halo/throw out bearing( I've heard it being called a "yoke"), then the collar should be on a shaft behind that, but I might be wrong in this,I just don't know.

Any and all replies/help are appreciated!
sincerely,

I just finished splitting and reassemblying a 22 in order to add electric start. It sounds like you're on the right track, except that the clutch is not quite as you describe... what you're describing sounds more like a D2.
In addition to what you've already said, it is also necessary to remove the clutch pedal and cresent shaped lever that actually moves the throw-out bearing... without removing them, the yoke cannot rotate in order to release the ears on the throw-out bearing yoke. Here are a couple of pics of what it looks like in there... Wayne

Whoops! I just realized its an Orchard Model with a clutch lever, not a pedal... so I'm not sure how yours is actuated... disregard the part about removing the pedal and cresent shaped lever.

thank you bcwayne for the info.!I guess I'll add clutch pedal & lever assy. to the "remove" list. I was basing my knowledge off of a D4-7J we had to split to swap engines & what I could see through the service/inspection cover on top of the 22's bell-housing.

Exactly what I've got to do to my 1935. Only the ears on my yoke are worn out and I'll either need to replace it our build it up and machine it out to fit the pins.

While it's apart, I probably ought to replace bearings and reline the clutch.

yes take the short clutch lever off, so the yoke will rotate a bit more and not get sprung.... it will not come apart otherwise,,, even if you try really hard with pry bars and such.. Dont ask how i know this!!! after doing it right, the tractor just fell apart easily. You are doing the right thing by " bouncing your plans off this BB" before you proceed. I have done so many times, (except this once with the clutch), after all, how hard can it be???? Lesson learned.... the hard way.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
