Front PTO clutch questions

[heinriech]

Ok update:
Stacked both units together.

One out of the parts tractor measures about .050" clearance between drive and driven:


One out of the tractor is no clearance as it was when it was mounted on the motor (picture is showing feeler gauge not going between the drive and driven):


And just for fun swapped the drive plate from the parts motor and the driven plate from PTO out of the tractor. Clearance is about .130". So I understand why you don't swap parts between the two. The magnet is probably not strong enough to overcome the springs when they are displaced that far already.


There is a decent amount of wear on the back of the driven plate from the parts motor. As the bearing feels a little tight. I will try to clean and degrease see if it improves.

Any other input? All input given this far is very much appreciated.

Is the shoulder of the spacer, seated against the inner bearing race when you are checking clearance of the problem clutch?
@ this point you prolly are going to have to use the one off the kt parts motor.
it will pull down to the .010 gap when you put the stamping over it and tighten the adjusting nuts.
You can swap the bearings if need, they push out, just support on the bore the bearing is in, not on the pulley, as they deform easily.
While it is apart, check your magnet coil insulation, usually they flake off.
They can be easily recovered with a 2 part epoxy, some use JB weld.
just flow it into the windings while it is setting level.
Sometimes a tight bearing can be saved/lubed with a syringe filled with light chassis grease if it is not "rough" just tight/dry,by injecting it carefully under the seal lip.
the warmer the grease the easier it injects.

Ok got the part kt PTO on the magnum. Everything seems to work as intended. I am around .015" gap. Should I tighten it up? Seems as though the engagement is a little violent. Will tightening up the gap help this?

Overall the PTO engages quickly and seems to have good power (not slipping) and as soon as I shut the switch off the snowblower stops immediately!

As it should, the brake is working.
if it won't engage when hot, tighten the gap to .010
don't throw the other pto away, good for parts.
Always good idea to engage @ lower rpm's

Thanks. I really appreciate all the help with this machine. Breathing new life into this old tractor brings a smile to my face everytime I over come a challenge! On to the next challenge, replacing the leaky valve on top of the hydro.

Get yours rebuilt by the guy on ebay, less expensive than new and does good work.
