Thread: T/C leak,has anyone got a guaranteed fix.

I like that idea,the inter shaft is a gift that keeps on giving,maybe capping it is the go. Pat

Pat if you have someone local who can mill your case
I have a few slugs of 4140 and could spin you up a capped sleeve
You can be test case one before I do mine

Why not capped with a welsh plug

I was reading and thinking 'a welsh plug could do it'.
I have the leaky 'box syndrome. From what I can see in-situ, the (dealer? more likely than not) used the old blob of silastic trick, which seems now to have grown into a bit bigger leak. Well... big by my standards at least. Maybe I'm not a true landy owner yet. Some measure their leaks in litres.

or square metres as is the case with my rangie....

I can't believe I'm going to admit this on a public forum, but here goes....

My rebuilt t/case leaks from the sleeved intermediate shaft too.

When I had the machine shop do it, I gave them a shaft plus my measurements and the thing was damned near a press fit when it came to assembly. It was a tight push fit like a gudgeon pin.
It was so tight I couldn't get the O ring in without it shaving it, regardless of tools I made to get it in the bore. It didn't help that i forget to get them to put a slight lead on the bore.
I think I went through three or four O rings before giving up, I had to get it all together and back on the road.
Between an engine rebuild and t/case rebuild it'd been off the road for about three months.

I knew it would leak, so I smeared the shaft externally with RTV.

I noticed a leak after about 3000km (an ever so slight one) and has a smear of Gear 300 atm.

I have to say it's the least the t/case has leaked in fifteen years of ownership, and interestingly the D2 has a dry t/case, but I must admit I haven't checked the fluid level yet, too many other bloody issues like breakdowns, coolant leaks and diesel leaks so far !

One of the issues with sealing off the end via the capping method is that mostly the cases leak there from the shaft eating its way into the case. Obviously an old/hard and useless o ring is also a huge factor, however unless a sleeve is inserted to stop the movement of the shaft and then a cap of some kind then you are still not fixing one of the underlying causes.

Just guessing, guys....
