Happy Days.

It's just a gasket on the older style LT230 and just a silicone bead on the later ones like yours. I think the cover has the input shaft rear bearing carrier in it IIRC, but it should just come straight off.

Oh, and don't be tempted to stick a gasket in there - it will act like a shim and change the preload on the input shaft bearings. Just remove, clean, bead of goo, then reinstall.

Cool. Thanks mate.

I'm pretty sure that's where it's coming from so I'll nick up the bolts and see how it goes but if it continues, I'll take it off and do as you say.

Happy Days.

As Gav says, it also preloads the bearing. The cover you see is retained by the 6 bolts. These bolts also retain another housing that supports the bearing outer race. This is located by two countersunk bolts initially and then further clamped in place by the cover and its 6 bolts. You will need to remove the cover and then the race carrier and seal between both or the leak will remain. Its not a big job, and not a job where you can loose bits into boxes. With both the cover and the race carrier removed, you will be able to slide the transfer box input gear out and see what the gearbox output splines are like and the mating splines within the gear you removed.. If your gear has cross drilled holes then the splines should be good. If not, then there'll prob be a bit of what looks like dried grease in there. Clean it all out and refit with some nevercease on the splines. There is a product called 'Bluemax' that I rate highly as a sealer. As Gav also said, if there's a gasket in there, replace it.

Thanks mate,

I'll definitely give it a go myself but I have a trip to the Gibb River road coming up and I don't want to go playing around with bearing pre-loads and removing shafts before I go.

Thanks for the extra info.

Happy Day
