What weight oil and how much in my '67 Triumph tiger Cub clutch and trans? Is the clutch and trans oil different?

Thanks.

Mick

The old manuals recommend 200cc of 30 grade oil in the gearbox and 200cc of 20 grade in the primary chain case.

These days I use a 20-50 multigrade in the gearbox filled 'til it overflows from the level plug in the centre of the drain plug.

For the primary chain/clutch case I use Auto Transmission fluid, just enough to keep the chain lubed but not enough to make the clutch slip.

Not had any problems.

I also use fully synthetic in the engine. Not had to rebuild it in 3 trials seasons of regular trials use and it still doesn't smoke. Just change it every 3 months or so.

Hope this helps

what grade of oil do you use ? 

 

i use 10 - 40 semi synt is that ok or should i use higher viscosity oil ?
