Gearbox oil weep

Is it normal to get a very small oil leak from the gearbox ? Last time I did an oil change the undertray was stained under the selector shaft which I cleaned up . Doing an oil change again and its stained again. I topped up the gearbox oil ( easier said than done )just in case but it appeard fine. More oil went up my arm than in the box and it over flowed ok.

It could be leaking from a number of places - probably worth checking the driveshaft seals and the selector shaft boot (I guess there's some sort of seal on that too).

The gearbox is filled for life so I wouldn't expect any leak at all. I do remember that sometimes the boxes were overfilled a tad and when you got them really hot they spewed out through the breather, but that would be the top side of the box.

Cheers,
Robin

Mmmmm today is the first time I checked it . Oil spilled out when I took the plug off but I thought that may be due to the jacking position . Its only done 9k miles so may have been overfilled at the factory .Drive shaft are ok . I will investigate tomorrow.

ScottD had a leak from the selector shaft. Just popped the seal back in IIRC. I had a driveshaft leak, pig to change the seal as the driveshaft has to come out.

You sure it's gearbox? Apparently the best way to fill the bugger is thru the speedo drive hole blank (Metro box remember!) take out the fill level plug and top up until it spills. I'm going to try this soon to check my level is still ok.

That would have been really easy doing it that way

Fluck !Hey if you dont do these things you dont learn. PM me your address and I will send you some oil . Land Rover MTF 94 . I found out it was filled for life after getting the oil .

Here's my leak

Like Rich says, I'd read on the BBS archive that popping the selector shaft seal back in should of fixed it... except it wouldn't just 'pop back in'

So tis still leaking

Cheers 10k but I was expecting to loose more when I did my seal, I have a spare (£11.99 FFS!) bottle of 'box oil. Castrol SMS-X or something. I'll use that.

BTW I didn't find out about the speedo shaft thing till after I did mine either, hence the mess of oil so I can't see if it's still leaking

I only got a bit into my 'box, it was still mostly full, but feck me does it run quietly. Sounded like a washing machine full of scrap metal on overrun before, now it just quietly whines to itself.

I take it this "filled for life" gearbox is similar to your "no loss" hydraulic system on the jets???

Something like that, for those that don't know:

"When it stops leaking it's run out"

And

"We just have to top up the no loss hydraulic system before you fly"

The aircrew always like that

No, what it really means is that there is no service schedule for checking it

Obviously if you get a leak you will need to (a) fix it and (b) fill the box with oil again ...

The gearbox oil should be checked every A service.

Single drop on the selector shaft today . Cleaned up and I will check again tomorrow.
