Thread: Adaptor shaft

Lotza, you got any other reference to HTE 571 - searched aulro and only got a reference to loctite 571. On the general web nothing after a quick scan.

Hi Guys I'm looking for a summary of the spud shaft and thought it is time we are all in the same headspace.

If we wish to keep the original Land Rover prop shafts:

1. What is the space between the back of the MSA (rear cover off) and the front of the LT230? (Vern 173mm, AM's is 175mm)
2. What is the distance from the rear face of the MSA and the rear face of the MSA drive flange?
3. What is the pitch circle of the MSA drive flange?
4. What is the OD of the MSA drive flange? 120mm??
5. Does the mainshaft and nut protrude rearward of the face of the MSA drive flange? If yes: How much and what OD of nut?
6. Does the MSA drive flange have a flat face?
7. What is the measurement from the front mounting face of the LT230 through the 42mm seal before the bearing race supporting the input gear?
8. What is the full depth/engagement of the spud shaft into the the input gear (from the front face of the LT230)?

Vern. I think it is a good idea - just couldn't help the analogy If the alibaba source could deliver as expected then I would probably follow you in a purchase and machining of the SAE10 and whatever spline - subject to price. But the splines would have to be cheap enough to buy several. I would prefer as little custom work as possible.

At this stage I am still thinking of buying another Outcast as 'my get out of gaol' card. But still think a field serviceable unit would be better.

The HTE 571 is the replacement hub drive flanges on the Series Land Rovers. (Like the HTE 859 is the replacement for the Defender/Late Range Rover/Disco 1 drive flanges)

From reading several posts above it seems they will be 113mm not the required 120mm.

That is not to say that we couldn't get Barry to make up a special batch of flanges at 120mm with a 42mm OD seal face protrusion with the 24 spline from the HTE axles cut into the flange.

If I read correctly earlier in the thread, someone mentioned that early 10 spline Rover axles will fit into the input of the LT230.

In that case Hi-Tough Engineering, have the correct diameter shafting to make the spud shafts and also have the brooches to cut the 10 spline for the input and press fit 24spline brooches for the flange end.

Someone up in Brissy may have good contact with Barry W to discuss the situation, otherwise I have had contact with Barry and Mal going back to when Maxidrive made up some special axles to match Stage 1 CVs to ENV diffs. Barry did the machining and I have had intermittent contact with him since.

High Tough Specials wont be cheap, but they have the tooling, the experience with making shafts and having them hardened.

While I still don't like the idea of flanges and would prefer a single piece spudshaft. If HTE would do the specials for us, they would probably be reliable and cheap enough for us to carry a spare.

can only answer number 1, 173mm for mine, AM's is 175mm. I need to remove mine to measure more accurately.
Can't answer the rest as its still in the car

So what are you doing muching around on a keyboard! Hop to it!

After the issues you had recently I can fully understand your having a break from spanners.

For me this is a medium term project ~ 12 months, but I waited for several years for someone to come back online because I want it done properly.

I'm even thinking It should be a top loader adapter, (perhaps like a machine gun, where you have a belt of shafts and when one breaks, the ejector mechanism withdraws the broken one and loads a new one )

Waiting on a 1.222 transcase (hop to it lockee) which I want to trial run to see if the gearing is better and whether or not I need to change to a msa5r, as soon as I test run it, out it all comes. THEN I can measure it all up and give a bit more of a damn about all these threads

Is that the Lockie at Mokinya we all know and love so well? Must head down there again, if I hadn't had my 83YO mum I would have run up from Colac a couple of weeks ago)
