New Clutch Disk Very Tight
 

I've installed a new clutch assembly to my 73.
Everything is new, plates, springs (teaser/main), driveshaft, disk etc.
My question is this:
The disk is sandwiched between the 2 pressure plates and will hardly move.
Tapping it moderately with rubber mallet allowed me to line up the drive plate holes.
However, even with pedal fully depressed it does NOT release the clutch disk enough to roll the tractor freely.
Could the new driveshaft spiral pin holes for the plates be drilled too close together for proper function or ...
Do new clutch disks need to be run a little to break in?
Tractor is being rebuilt from ground up so have not run it.
:bash2:

Need a pic, will it will roll if you put it in neutral with the clutch pedal up?

Did you adjust the brake rod for the correct pedal free play?

You would have the internal brake, do you have the brake rod already installed? If you do perhaps the brake is adjusted to the point that it is limiting the clutch release arm movement. You might try disconnecting the brake rod, then try to adjust your clutch.

Edit: Dart1917 beat me to it.

Gentlemen,

Brake rod disconnected.

Rolling the tractor in neutral causes the engine to turn over...with or without the clutch depressed.

I see no free play in the rear clutch plate (with the groove (not spiral pin hole) when the clutch in depressed.

Here is a pic of the set up.

Thanks for any help.

Additional info
 

When I assembled the clutch pressure plates and drove the spiral pins in, it was already tight enough that the disk would not move.

The rear spiral pin was already bottomed out in the groove when assembled with the front pressure plate and disk in place....

They look like custom pulling parts to me.
Did you get everything as a kit?
3,2,1, install and go?

Rear clutch plate needs be have free play. Sounds like the hole in the drive shaft is off centered or the slot are too narrow or pin is mushroom some.

Maybe it is me...but the rear pressure plate maybe on the wrong side of the disc. Rear pressure plate should be slotted. It looks like it just has a hole.:bigthink:

It does look like it has a hole.
