Gearbox oil - does it have to be exact?

[700newtons]

I have relatively easy access to the drain plug and filler plug of my 160. However, the level plug is awkward to access in the transmission tunnel (it is 3/8” square hole, but I can't squeeze a wrench in). The handbook says the capacity should be 1.2L

I'm going to measure the volume of oil carefully and just fill it.

Any wisdom gratefully received....

Can you make a round hole in the wall of the tunnel to access it .... then fit a rubber grommet to fill the hole ?

Can you cut down a wrench to fit?

LADS top tip:-

To fill - use a normal oil can (readily available from Halfords/Machine Mart) with a bit of clear plastic pipe (as used for windscreen washers) pushed on the end.

I'd work out the access while you're still building. You need to be able to check the level. You've got the two main options* already suggested above. You could also use a dipstick through the top cover if it has one.

* And I've posted my canoeish experiences with a cut-down key and a ratchet spanner...

Thanks for the ideas.

For starters, I think I'll try to fashion a slimline wrench from a short length of 3/8” square steel from eBay and a spanner.

Dumb question: if you've got a filler and drain plug, what's the point of a level plug? A dipstick would be less hassle, I'd have thought. It's possible that this was easy to get to in the Suzuki original, but is inaccessible in a 7 chassis.

I could very easily be wrong about all the above
