Oil and gear fluid volume for 1979 GS850G

[Anonymous]

I just did an oil change with filter and I'm changing the gear fluid tomorrow. How much oil and gear fluid does my bike hold? This is my first time and I can't find any specs on that.

Capacities for a 1979 GS850G:

Engine: (change) 3.0 qts (US)
(w/filter change) 3.8 qts

Secondary gear oil: 11.5 - 13.5 oz (behind shift lever cover)

Final gear oil: 9.5 - 11.2 oz


Engine oil: 10W/40
Gear oil: Hypoid Gear Oil SAE 90, API grade GL-5

This is taken from the Suzuki factory shop manual.

Thanks! What exactly is "hypoid" gear oil?

[Anonymous]

Hypoid gear oil is just the 80W90 gear lube that you can get at any auto parts store. Suzuki specs say 90 weight, but I've always used 80W90, easily available and works fine.

Warning: it smells bad...

Good; that's the stuff I bought and the guy at Fleet Farm said it would work fine, but that word "hypoid" scared me a little. Thanks.

The beveled drive gear oil has a level indicator LOOK behind the shifter lever & you will see a 10 mm bolt remove it REfill gear case until oil drips out of the bolt hole
rear dif just fill to the bottom of the threads of the fill hole
