Hey..
Thanks for the help guys..

I managed to have new axles made.

Crowns wheels from the local agent only come with the sleeve bush and the bearings inside the wheels..
At least now I have some great insight on the matter thanks again:)

yes, thank you for the clarification.

Ok, I don't know this unit specifically but Crown generally use sleeves to reduce the bearing inner diameter to the size of the axle and spacers to fit between two bearings at the SAME diameter as the bearing inner. An important distinction. If its a sleeve, it MUST be fitted.

This is a sleeve: http :// goo.gl / 5gx8g6

Hi, thanks for the reply.

Oh ok I shall give it a go.

I did try having the wheels with out the axle the sleeve bush but it has a lot of play on the wheels.

the metal "bushing" that goes in between the bearings is there to take up space, and can be replaced (more cost effectively) with grease.
The wheel needs to be completely filled with grease upon install, and will take over a 1/2 tube per wheel, but at 3 dollars a tube (what I pay these days on this side of the pond), it is less than a new metal bushing each time.
You could reuse the old wheel's "bushing", as they don't usually 'wear' out, but then you have to knock out one of the old bearing to get to that bushing, which may cost more (at 1.50 to 2 dollars a minute {90 to 120 an hour} labor cost currently what most forklift companies are charging around here) than new bushings or the grease.
