Mini Digger won't track straight

[HeliPilot]

Hi All
My JCB 8026 has stopped tracking in a straight line, one track is running much slower than it should.
Any suggestions where I should start first?
The machine has only covered 500hrs of relatively light work.

Has it started doing it since your Tiltrotator has been fitted? Is it a case the that the hammer line is getting flow? Causing one track to go slower?
Does the auto idle work?

I'll try it with the tiltrotator disconnected. But I think this problem started befor it was fitted..!
This machine doesnt have auto idle.

Many Thanks

rotary coupling seals bypassing -- I know it's only done 500 hrs but could be a Friday (or mon., tues., weds., thurs.) machine ???

Rotary coupling seals? I've never tackled anything like that, are they accessible from underneath?

not an easy job ... try swapping lines to drives left to right and see if the problem moves
