Thread: LT230 leaking at the rear - but where from?

I do recall that the layshaft can flog out its hole in the casting on these? Then it leaks there and the repair involves machining etc. Just to check it’s not leaking there before strip down…

Isn’t that on the front side, not rear, if the box though?

The intermediate shaft is usually the main culprit on an lt230, they flog the housing where the o-ring is and leak.. Sometimes badly, but that is usually at the front, I guess if it loose it could do it at the back, but I haven't had one apart for a number of years now.. Memory is a bit sketchy.

If it's the intermediate shaft leaking you may have trouble stopping it without getting it re bored.

I'll pull the hand brake assembly off and take a look. I can't tell where exactly it's coming from with it all still together.

Pulled the handbrake dum off and there wasn't really any bulk oil in there - doesn't look to me like it's leaking into the handbrake assembly. The drum itself was very clean and hasn't had oil flicking around inside it:




So I pulled the handbrake assembly off. I believe that tear drop shaped piece is the rear end of the intermediate shaft and it doesn't look to me like it's leaking there either:




I've cleaned it all up and filled the oil level back up so hopefully will now be able to see exactly where it is leaking from as it's a constant drip even when not being driven.




Could it be leaking between the FTC5095 Housing Assembly Rear Output Shaft and the Main Casing?



I don't see a listing for a gasket between these two in Microcat. Can this housing be removed and resealed with the transfer box in situ?

The rear housing can be removed/installed insitu.
Use your favourite sealant and use blue locktite on the threads to seal them.

Thanks. Found the section in Rave too:




It looks to me like it is definitely the rear output shaft housing that is leaking. After cleaning it all up yesterday here is the mess from overnight:





The black run off from the output shaft stub would just be degreaser and water from the wash down. The gear oil looks to be leaking from the lower portion of the rear output shaft hosing to main housing area. Nothing from the intermediate shaft area thankfully.

Where does the rear output shaft bearing sit? Does it live inside that rear output shaft housing? If so, would it be easier then to remove the rear output shaft housing and change the bearing on it while off the vehicle?
