Thread: Lt230se transfer box differential thrust washer inspection.

Looks like I'm going to learn how to set the input shaft preload. As the input shaft was tight, I measured the endfloat - 0.000, which technically is within spec, but there is 0, and then there is 0, and mine is on the tight side of 0.

Also, the bearing shells are showing signs of wear, and while it is not really bad, and I have reused worse - I may as well change both bearings while I am at it.

So off to get some parts ordered tomorrow, and I'll go from there. It's a bit of a pain, because to do this properly it looks like you have to buy a thinner shim than what you start with, assemble everything, measure up the endfloat, then pull it apart, order the correct shim for it, and put it all back together again... The shim goes in behind the rear bearing shell, and at least they have made it easy to get the shell out - there are releifs cast into the housing, so not a huge job.

I'll post the results, but it probably won't be for a couple of weeks - I am away with work all next week, so Ill be stuggling to get it done in time for the Wombat weekend me thinks...

Gav, I'm part way through my LT230 rebuild - been going on so long I can't remember which boxes all the bits are in . However, I have some shims here that might be of assistance in the fit/try process. Gimme a call if you're interested. You're actually at the stage where I stalled. LR Australia don't keep any of the shims in stock when I asked them. Makes it a very slow process to get right.

Well, have ordered all the bits I need - they had some stuff in stock - they just had to order the bearings and the spider gear shims (someone who shall remain unnamed went in yesterday and bought the set he had in stock) I was able to buy a whole kit that contains all gaskets, seals, o-rings, etc for the TC, and the prices are very reasonable - about $100 all up for the kit, and the bearings for the input shaft.

The only other thing I will need is the correct shim, which I won't know what size I need until I fit the new bearings.

Winner!

Thanks - if you can find those shims you have lying about I will probably be ringing you for a lend of them the week after next - I am away all next week and I have plenty on my plate to keep me out of trouble until then.

I'll have a rummage now. Have a couple of other things that might be handy too.

Found the following:

1 spare set of spider gear shims (doh!).

1 x FRC9928 shim - 3.20mm as shown here to be used for measurement of float. This was as close as I could get to the 3.15mm that is supposed to be used to measure up.

I also have the FRC9954 3.85mm shim that came out of the box I intend to finish. There's one that measures 3.78mm currently in my running box but that doesn't directly translate to a Rover part number because it appears to be an in between size.

Have you bought a new crush spacer for the intermediate gearset? Those bearings wear and you might as well replace them and the crush spacer, and if the intermediate shaft is worn you might as well spring for a new one of those at the same time. Pay close attention to the condition of the casing where the o-ring end of the intermediate shaft locates. The alloy frets up and then causes the leak again in quick time, not to mention allows the gear to rock and roll as you go on and off the power.

And nice shiney shims they where
Now covered in oil and fitted where they belong.
Even got the box bolted in tonight, just got all the bits that bolt onto it to go.

I think your on the right track Gav., do it now and you shouldn't have to worry about for about a decade
