Morning All

I have a slight Gearbox leak coming from the gear selector area, lads reckon its and forgive me memory gear selector oil seals. However before i get round to fixing it how do i check my gearbox oil levels.
Also draining and putting new oil in is it tricky?
Thanks

I use something like this for filling/topping up diffs/gearboxes:

Generally (details vary slightly, from box to box) there's a drain plug somewhere on the bottom and a fill/level plug somewhere on the side. Checking the level is a bit tricky, generally unscrew the fill/level plug out of the side and see if oil runs out. If it does there's plenty/too much in. If it doesn't then poke a finger in and see if it comes out with oil on - level about right. Or just pump some more in until it runs out.
I've given up checking levels, I just tend to drain it and refill completely at proper service intervals.

If it's a Triumph "single rail" manual box.... they blow a bit out of the breather and the selector rod seals can also leak. Generally the top of mine (Spitfire, not Dolomite... same box) is damp with EP90.

I just an oil can of the old fashioned type with a lever
for your thumb to manually operate the pump for the oil
