Lifton LS750 dumper bearing trouble

[Russ1669]

Hi All, I bought an old LS750 dumper which runs great even though it's 25 years old.
I'm a bit concerned about the amount of play between the front and back halves of the chassis. There is a gap between the two plates that I presume are to allow rotation between the front and back halves, but there is noticeable movement up and down (especially when you are sitting on the machine and it is balanced).
Does anyone know if this is normal or should I try and tighten the large centre nut? I've also tried finding a user manual and parts list, but so far no luck.

shows a close up of the gap between the two plates. Any advice on this would be happily received as I'm a bit scared that the two halves might separate!

so that's the horizontal swivel, with a vertical swivel to the left in the pic - like a universal joint basically - different set up to most frame steer m/cs ... I'd give it a nip up - any grease points to lubricate the face plates ??

There are two bolts, one top one underneath the big nut in the middle give them a nip up to

But the main play will be in the vertical pin that it steers around I’ve put a set of bushes in mine to get the play out

Oh by the way it won’t fall in have

Have you just bought it if so is it a hydrostatic or has it a clutch and gearbox and what kind of money was it as I have one sat here that needs to go…………..I think

Hi all, new to the forum and working on an old Lister LS 750 to get her back up and running again. Anyone have any ideas where I can get hold of a workshop / maintenance manual before I get much further? Thanks
