@Spike188 any words of advice on getting the swing cylinder(s) off the frame?

Here are pictures of the swing assembly. To remover the swing cylinders, remove the swing arm 16 tooth pinon gear. It is held in place by 2 socket head set screws. Once it is off there are 4 clamps / 8 bolts that hold the swing cylinder in place.

The last post was March of 2023. I have been dragging energy wise since then but looking back to then, a lot has been accomplished. If only it could have been more.

One of the hold ups on this restoration is the axle housing wear. The PO ran it out of oil. The right hand axle has cut through the outboard bushing and into the housing at least 0.070". 2 machinist buddy's gave advise on a plan of action.

They loned me an angle plate and a small boring bar.

The challenge now is mounting the axle housing to the angle plate and getting enough mill throat to insert the bearing bar into the housing.

This is a mockup of my thought today. With the 6 stud bolts removed from the housing, it can be mounted to a 1" thick aluminum plate. The plate will be clamped to the angle plate. Alignment will be confirmed by inserting a 36" long shaft through the housing. After indicating parallelism the shaft will be removed and the axle can be bored.

If you have enough room in your mill ,that is a good plan of attack . I don't in my little mill , so I would have to make a line boring jig to do that job. Are you going to make an over-sized bushing or sleeve it ?
