Thread: Transmission brake transfer box problems

Yep, unless you can find anything obviously dramatically wrong, you're on the right track to clean it up, replace the seal and tighten things properly. That may be enough to bring it up to the serviceability you need.

Agreed. The nut on the output shaft should be locked with a split pin.

Thanks guys.
I'm hoping to get away with just degreasing everything, tightening the nut and fitting new handbrake shoes and a seal. OK for use on a farm ....
The nut on the gearbox mainshaft that needs the special tool (or a chisel !) was loose as well. Mind you I was removing a Fairey overdrive and had to take a coverplate and gear from a spare gearbox and the nut on that was loose !

More pictures to follow if I get time to work on it at the weekend.......I'm away in Country VIC and a branch fell on the house last night so I have a bit of clearing up to do when I get home.

The nut on the drive flange does not set the bearing pre-load. It is set by shim thickness under the speedo drive housing. Set the pre-load by removing shims and testing with a spring balance as detailed in the workshop manual.

If it is only for the farm - degrease the shoes with de-greaser; boil some water in an open 20 litre drum outside somewhere where it is safe; add a cup of washing detergent and add shoes to the mix.

The old boy who used to be the mechanic next door, said this was a common method after the war when things were hard to get, or hideously expensive. When I asked how long it took, he said "About the time to drink a carton."

Let us know if either are true

The nut on the drive flange does not set the preload, but it does apply it. So a loose nut means no preload. Ideally the preload would be reset, but for the specified application it is likely that just tightening the nut will be close enough.

Charlie,

If you look carefully at the photo the friction material has all but disappeared, difficult to tell under all that oil & dirt.

I remember someone years ago soaking oily motorcycle brake shoes in petrol, scrubbing of the worst of the oil then taking them out and setting them alight.
Not sure if it worked but I wasn't game to go pillion on that bike any longer......

With the current rain and clearing up from the branch that fell on the house I might not get to look at it this weekend....
