lift arm bushing and pins

[december45]

My 743B bucket and up and down motion is getting kind of sloppy, i am just now starting to see a small amount of lateral movement in the pivot points of the lift arms, at least enough movement that it is of concern; replacing the bushings and pins, is this a tough job can it be accomplished with the arms still attached to the machine, ie do one pin at a time? are there any special tools required? any help in this would be appreciated, or head me in the right direction to find out about them, thanks

If you are talking about the upper arm where it joins to the rear of the machine, there is no bushing, only a pin. No special tools are needed, just a spanner, punch and new pin. I use the new pin to knock the old one out and new one in.
Its a poor design that when it wears, you need to cut te old boss out and weld a new one in... Same with the lift rams, there are no replaceable bushings....
