Before tackling the lifting of the cab off the tub, and the wire brushing I had a good look at the controls for the front loader, I noticed a lot of play in both levers when I first drove the machine so knew that they needed attention.
From this first pic you can see that both levers are falling to the back and cab side rather than sitting upright:

The plastic in the UJ cage is heavily worn where the brass pins locate and the bushes in the outside lever mounting arm were not in the first flush of youth either
Then in this view it's clear that one of the rod ends didn't leave the factory looking like it does now:

Wiggling the rods around showed that, bar the rod with the rather sick end, there was a bit too much play in the yokes that run into the pistons on the valve block.
So I took the opportunity to disassemble the levers, remove the defective rod end, take out one of the clevis pins and the outer lever assembly.
Stripping the lever assembly down the pivot that mounts to the 'tree' is bushed, however the lever arm pivot isn't. Having a dig around on the web I eventually discovered that the rod ends and clevis pins that are a circlip type are made by Dunlop, they are also imperial size and thread fittings.
I found that I could order them through these people:
https://www.onlinebearings.co.uk/ who rather handily also sell amongst other things 'Oilube' sintered brass bushes. The Rod End is a 5/16 UNF righthanded thread swaged retained ball type (DIG312-RH) and the clevis pins are 5/16" (NBI312). The large bush was actually made up from two I discovered when I pushed it out with sockets in the vice, the closest size is a 5/8" bore, 13/16" OD and 1 1/4" long, I may need to turn it down. For the lever arm pivot I bought a bush 5/16" bore, 7/8" OB and 5/8" long, I'll need to ream out the lever arm pivot hole to take it and possibly add some shims to make it nice and tight. I will also need to 'discover' a new 5/16" rod from a bolt...
This is how the removed outside lever pivot assembly piece looks with the bush pushed out:

And then, of course, the dead rod end and worn clevis pin:

Finally, another thing I spotted was this:

It tends to help if there is more than 1 screw out of the 3 holding the hand throttle lever in place!
