6400 Torsional Dampener Issues!!

[mastercraftka]

We have a 6400 and one day I was moving a bale of hay and I lost hydraulics light came on and I started to get smoke from under the cab. Upon inspection i noticed that the smoke was coming from what you see in the picture. So I know nothing about this and what it does. What am I up against and what does it do?

6400 parts catalog shows a serial # break @ <120756 for torsion damper utilized with PQ trans. AL79074 @ $1300.

Dampener helps absorb shock loads when changing gears or tractor directions.

Ok it must be more serious than a piece of rubber then because we have no tranny or remotes.

No trans or hyd's indicates damper has failed!

How big a job is that replacement?

I know one thing you don't want to get that black goo on you!! It don't come off very well.

I guess I own one of those. Who knew? I got my PQ used, I hope this part is good for a while.

Makes no sense to me from what I can see, why this would disable the movement of the machine.

I PMed you....It sounds like you remove the right rear wheel and tilt the cab to the left after disconnecting the clutch and throttle cables etc.
