GEARBOX OIL CHANGE PROBLEM

Postby k690bpp » Sun, 07 Nov 2010 19:25:29 UTC

i followed the instructions on how to do this from here...

http://www.impee.co.uk/transmission_fluid_change.htm

but when it came to undoing the drain/refill plugs i noticed that mine were not the same as in the how-to.

no big deal as they could be undone with a hex bit. only problem is that the plug has been rounded off! :shock:

it looks like someone has tried to get the nut off and using to small a hex bit and then used a pair of grips aswell. :!:

anyway the nut is knacked i tried to get it off using a hex bit one size bigger but there is no room to whack it on.

any ideas?

thanks.

Can you get someone [who knows what they're doing :wink: ] to weld a larger nut over the top? If so, remember to order your replacements prior to starting the job.

But first, I'd try one of those clever sockets with pins inside which are designed for just such a task.

wasn't me who rounded the plug, it was like this when i took the covers off but it does seem as though some complete wonker has been at it! :(

anyone used j-b weld? i was thinking i could use it to weld in a hex socket and then slowly wind on it?

i don't think the the socket with pins on it will work as the plug looks like this and a socket wouldn't fix over it...

If all else fails you could try using a cold chisel on the outside circumference of the plug. Just hit the chisel hard enough for it to dig into the steel then try to gently get it moving anti-clockwise by carefully holding the chisel at an angle and tappinig it with the hammer (if you see what I mean). Assuming you have room of course!

Your pic makes things a bit clearer as far as what you're faced with.

Could you get access with an air grinder with a small disc on to cut a couple of flats on the nut, enough to get an open-ended spanner on there? Or even file them...... :cry:

Try a stud extractor. If you can get a good sized one that's a good fit in the hole you stand a decent chance of getting the plug out without any violence :idea:

Get a similar problem to this on vauxhall sump plugs, tap home the allen key make sure it is well and truly in, then attach a set of mole grips to the outside and twist both at the same time.

this won't work, the plug is on the side of the box and theres just no room to swing anything, it's where the pipe goes in...

no, there no way to see enough of the plug to grind on it.

this is probably a last resort.

Hammer and chisel to the edge of the plug, will dig in and might just start turning it? Be careful of the alu casing btw.
