Disassembling Trex 600 swash

[Davewaddy]

Can any one please advise how to take a Trex 600 swash apart without destroying the unit? The center ball is loose and I was wondering if the retension ring can be adjusted to tighten up the ball. I am not sure if the ring screws out or is it a press fit? Any advice gladly received.

Didn't think the Trex 600 swash was serviceable?
Can anyone else confirm?

The center gimbal bush in the swash was sloppy (sherical bush) that slides on the main shaft. I have been able to remove the play by tightening the nylon bearing bush, this has been achieved by pressing the bush from the inside until all the play has been removed and the sperical bush moves smoothly.
This may not be the techical solution and I may have distorted the nylon bearing block which has taken up the play but I now have no decernable clearance and a very smooth operation.
I would be glad of any comment or pointers.

regards
Dave

Hi Dave, I take it you mean the swash upper/lower was pulling apart creating play??

Underneath there is a alloy flange that is pressed in place if its this thats moved you can do a fix.

Before you press it back together clean the exposed flange carefully and add a very small amount of red loctite for example with a pin, then squeeze it back into situ. (make sure not to get this anywhere else)
You then lightly centre punch the joint between the two alloy parts creating a small dimple for an interferance fit. Just do that evenly spaced every 120deg.

It doesn't take much so dont overdo it.
