Has anyone taken apart and re installed a case 446
front pto? I took mine off while doing the repower. But even using the manual I must be missing something because I can't get everything to tighten down right and at the same time leave enough space between the clutch and plate.

The only practical advice I rely on is 1) ensure 100% all the parts are in there, in the right order, matching the cross section build up in the service manual (all shims, washers, etc), and 2) follow the instructions TO THE LETTER.

Can't describe other tricks much ... once you've mastered it, then it's like riding a bike. Do need to be sure the flywheel on the engine doesn't turn while setting bolt torque.

I have all the parts. I removed them from my tractor and put everything in a can, and I followed the case diagram to the T. But somthing isnt right.



Would someone mind posting a pic of there front PTO.

Might be that whoever was in it before you didn't get it right.
Like Brian said get the pieces like in the picture exactly and follow the directions. But the one thing the directions omit :banghead3 and had me baffled when I was first doing one is to hold the flywheel. I've got a spanner wrench I slip in the screen. Make sure the slots in the two cams are offset.
You don't say if your is the old style or the EZ Adjust but here's a pic of the EZ on a Kohler.

Happy New Years

My manual directed me to insert a screwdriver into the timing hole and engage the flywheel to hold it in place. But this was on a 14hp K321 Kohler. I'm not sure how brittle the Onan flywheels are but I don't think you're supposed to put a whole lot of torque on the flywheel in this particular operation. Nearly all the parts tighten against each other. (I'm sure you knew that CP7 but I'm saying it for the benefit of the OP).

On the EZ adjust, if this is what you have - my advice is to make sure that you have what is referred in the manual as "spacers" in the correct orientation and make sure that those spacers come together to straddle the "adjusting nut" (the inner one, not the more outer adjusting nut guide) once you tighten down on the whole assembly. If you posted a picture of your clutch, someone on here will probably be able to tell you what the problem is in no time.
Another thing - use the correct 1 3/4" wrench for the adjusting nut guide as it is usually the first thing to break. If you do happen to break something or the bearings are worn out, replacements available from Brian H)

I had some difficulty with my "EZ" clutch the first time, but as others say, once you figure it out once, you're set.

I just rebuilt my 446 PTO with-in the last few weeks, make sure the spring washers have some spring in them. The old ones I took out were all flat, I ordered all new washers and spacer's from Brian and in less than 1 hour it was like brand new. If you follow the parts diagram for proper placement you should be fine.
P.S. don't tighten anything to tight until it's all together.
