Gear Oil: what's the actual volume? O_O

Is it 110cc or 90cc? One version of the manual says 110cc, another 90cc. And one of the YouTube videos shows a person adding 110cc TWICE (which can't be right).

Also, any tips on measuring it? I don't want to overfill.

It seems the accepted range on this forum is 80-100cc with most people using 80 to 90

I believe that the larger volume is applicable if you've just done a complete teardown/rebuild on the gear case since the innards are all bone dry. The smaller volume is for a fluid change since there's quite a bit of lube still lurking in the gear case even after you've drained it.

Yep, Charlie nailed it. Use 90cc's for routine changes.

I measure what I drain and replace exact amount. It is always 100cc.

100 is OK but too much gear oil can cause it to leak out around the seal and possibly even blow it. Then, it gets all over your wheel and tire which is messy and can even be dangerous.

A fine opportunity to link to one of my all-time favorite jokes:

^^^^Been there Toksik and it was on my mind. No trouble with 100cc and 15k miles. But yeah, you need to be aware.
