Thread: Defender LT 230

When you say machining, do you mean having the Ashcroft adapter shaft fitted between the transfer case and gearbox? If so, there are plenty of places in Perth who can do it. Dover’s Automotive in Wangara did mine (I supplied the part).

I need to fit the new intermediate shaft steel bush supplied by Ashcroft. I have all the bits for a rebuild I hope? It’s been a bit of a struggle finding someone who knows what is involved, I’ll try them

They have done plenty of them. Hopefully they can help you out.

You're talking about two very different things. The steel bush for the intermediate shaft needs a machine shop with a milling machine to bore out the transfer case housing to accept the steel bush. I have done a couple but I'm a long way from WA.

As mentioned by POD - just to be certain - do you have a leaking intermediate shaft that you are trying to fix? Im guessing so as you talk about an intermediate shaft bush.

Essentially the machinist needs to overbore out your aluminium transfer case housing to accept a bushing made from steel that the intermediate shaft will ride in.

Surely a few photos of the thousands of people who have done it in their backyard shed should probably suffice?

here is a perfect example from POD
LT230 intermediate shaft

I imagine if you wandered into your machinist shop with the cleaned case, the intermediate shaft and the bush they would have a pretty good idea of the job in about 3.5 seconds. I can assure you removing - disassembly - cleaning - reassembly with an ATB and re-installing will take infinitely longer than setting up and boring the case.

Most (all) machinists won't want a bar of the time consuming spanner throwing - you just need to get them the case / shaft and bushing. If you are remote and can't be off the road for long maybe look at finding a wrecker case that you can build up and then swap in?

Just something to note if you look at that old thread of mine that Roverrescue has quoted, where I did my first couple; the bush does indeed need to be stepped. My first one migrated inward despite installing it with 'permanent assembly' loctite (don't know about the other couple I didn't step!). Live and learn, they say. The gearbox will stop it migrating outwards, so the stepped bush needs to have the larger diameter to the outside of the housing.

Interesting POD,
the couple I have done I stepped following AncientMariner technique

I clocked in that thread that you hadn’t stepped the bush

I’m not that surprised that it migrated
Stepping gives whatever flavour locltite you use both a larger surface area to retain as well as retaining along a different plane of force

As you say live and learn

just to add...

While I have a local machinist do mine cases, its 3 or 4 cases at a time due to the setup rather than the actual job thats time consuming. also due to his workload its generally round a month.

What I recommend to the OP is simply buy a empty case that has the steel insert already done from Ashcroft in the U.K
