The spud shaft can be replaced with the later version however the gearbox output shaft and tfr case input shafts also wear - if caught early enough you can get away with just the spud shaft but you may have to replace the gearbox/tfr shafts.Quote:

Paints have made huge progress the last 10 years so there are cheaper option which have advantages over galvanising. Just my cents worth. m
We might be having a language problem 🙂. I've looked at the parts catalogue and microcat, but can't find a 'spud shaft'? Please elaborate...cheersQuote:

Oil has trouble getting in there causing wear so the later spud shafts have holes drilled in them to let oil into the splines.
A google search of spud shaft aulro will through up lots of information. a few examples

These are just a few referencing the spud shaft that can be removed without dismantling the gearbox/tfr case.

spud shaft - bolted to gearbox output shaft
Ashcroft Transmissions
spud shaft goes into this input gear located in transfer case (what you see when you take the rear round access cover off)

Your LT77 doesn't have a spud shaft, that part is only fitted to ZF auto boxes.Quote:

Have vague memories of separating a transfercase from a gearbox in an old RRClassic to find a fine spline 'spud' inside another fine spline 'spud' attached to the gearbox output shaft - maybe LRovers way of adapting the gearbox to different configurations?
As Dervish indicates, some output shafts on some gearboxes go straight into the input gear in the transfer case - no intermediate spud shaft to take the abuse. If you get bad wearing in this kind of set up then you are potentially faced with a gearbox rebuild to replace the worn output shaft as well as replacing the input gear in the transfer case.
Having also done a ground up restoration I agree with most of what manic says and others.
I have a galed chassis and firewall. But for a lot less effort overall you can substantially reduce the risk of both rusting. You just need to put some type of coating over at risk areas on a regular basis.
Epoxy enamel touch up over exposed areas of the diff is quite sufficient without sandblasting.
Three quaifes is also pretty extreme. I have a trutrack in the front. It's been so good I can't justify spending more to get more traction. I've only lacked sufficient traction once since fitting it.
Fix or replace what's needed. You'll spend plenty doing that.
Appreciate the help guys...these posts have changed my perspective. Will focus on repairing factory deficiencies for now...upgrades later. It'll give me something to do in the future.
Confirmed my output shaft goes directly into the input gear (no spudshaft). Both were wore and are getting replaced with Ashcroft parts...I'm going to go ahead and rebuild both while I have them opened up. At this point I'll have an entirely new drive line post crankshaft.
Cheers!
