Gearbox oil

[kwallace21]

Hello all,
How much oil do I put in the gearbox of my 2011 TC Gsa ?
Some say fill until it reaches the filler hole and some say a certain quantity.
What's the definitive answer.
Thanks in advance.

Bottom edge of filler hole should do it

Any idea how much that is ? I have just over 750 ml left after doing my FD oil change.

I think about 700ml usually does mine.
I can definitely change the FD & gearbox oil using 1 litre of oil (though I put 180ml in the FD - controversial I know).

you are about a 100ml short ,i think it is supposed to be 800ml for a refill ,but i always found it to be 850ml till it started running out again.

As long as its GL5 you can mix brands, doesn't matter if that helps ?

Well you can on the 1150 anyways

On reflection fizzer I'm sure you're correct. There's virtually nothing left from a 1 litre can after doing both, therefore 750ml will probably be just short unfortunately kwallace.

I did my FD first with 200ml and then did the gearbox. Oil was just appearing from the box filler/level so I'd say its 800ml less whatever is stuck inside the oil bottle walls.

I used the posh 75-140 full synth from Millers.

200ml of 85w-140hd in my FD
And 800+Mls (Valoline SYN POWER fully synth 75w-90)
For me

I'll grab another litre of the gearbox oil then just to be safe. I can use it for numerous FD oil changes later.
Thank you for the replies gentlemen.

Haynes manual for the TC bike says 700ml.

That's what I did last time and again this weekend.

But don't ask about my final drive......

 

[Beemerman59]

I fill to the bottom of the bolt thread - takes about 900ml.

Haynes also says 180ml for the final drive but BMW began with 220. With the way FD bearings go titisup I prefer to use at least 200ml and will try 220 next time.

Is that with the bike on the side stand?

Yeah I know, but I go with 200ml.

200 ml more than the recommended amount?

is that wise right?

That's about 25% more oil than recommended.

I have an 1150gsa and loads on here's said fill it to the ottom of the thread it will be fine, which was almost a litre, it's recommended 800 ml. Or 1 lite after a rebuild.

Funnily enough my fkn outputs shaft seal went last year, needless to say I now stick to the correct text book levels and have had no issues thus far.

I'm not saying overfilling caused it but it couldn't of helped.

Not after a forum scrap just wondering why people are filling past recommended capacities

They all have g box oil level plugs ? how can you get the wrong amount?? You pour oil in untill its up to the fill hole.
If I remember correctly my 1150 was 1 litre for the gearbox cos I had to buy two bottles to do a final drive oil change as well.
Why would put in less than up to the correct level?

Exactly, you could only overfill if you laid the bike on its left side ( gs1150 ) and topped the box up.

If I remember correctly, the OEM tech manual says fill it to the bottom of the filler thread so that's what I do. Been doing the same on my K1100RS for the last 20 years and no issues.
