Montesa Cota 172

[Brigalow]

Anybody know the type & quantity of oil for clutch/gearbox for Cota 172. 76 model?

[JC1]

I have a factory 172 Cota manual which says 900cc of 10-30w oil in total for clutch & gearbox - which sounds a bit high for such small crankcases & is a good deal more than they list for the 247 & 348 engines.

The two factory 123 Cota manuals I have list diff specs to that & to each other! And it's the same engine.
One says 600cc of 10-30w oil in total for clutch & gearbox
The other says 300cc of 90w oil for the gearbox & 200cc of 10-30w for the clutch

A Clymer manual lists 600cc in total for Cota 123 clutch & gearbox. The 172 isn't listed

Clear as mud?

Thx JC1, 900cc of 10/30w is probably correct, I got the same answer on another forum & yes it sounds a ton to much, the stuff I drained only went to about 500cc & smelt like gear oil, musta bin changed recently, it was a lovely shade of blue. Re the differences in manuals, later model cota's seem to have different specs to earlier ones, something worth keeping an eye out for.

Hi, see you mentioned 2 different oil quantities for Cota 123, you would happen to know which value is for an early 80's White tank model? I'm struggling to find any info or a manual. Engine/frame is 28M
