Transmission Oil

[T250K]

     Anybody able to advise the correct grade, and quantity of Transmission oil for a 1975 Husky CR 250 mag please ?
         Thank you,         T250K.

Manual says SAE20 but any light grade motorcycle specific trans oil is good (I use GRO gear/trans), or you can use ATF (cheaper) if you're happy to change it a bit more regularly. 1600ml.

Used ATF in mine for 7 seasons ran well

BK - that's one heck of a lot of oil.

My 1974 400 takes 500ml of ATF in each fork leg and 1 litre in the box.

Husky's take a lot of oil, 1600 ml in the older style engines, 1400ml in the newer style (1981 430 style).

Running SAE30 in my later Huskys.
SAE20 no longer available.
Briggs n Stratton engine oil is SAE30.

ATF must be resilient, just think about how much work it does in an Auto trans, gets cut to pieces in the converter and gets changed every 50 or 100 thousand K's.
I have run it in many bikes for a long time..

the best ATF is the ATF - F for early borg warners

i have tried a number of different oils in my kdx with slightly varying results to clutch feel, it has alloy clutch plates and have tried a couple of different sets of friction plates but I can definitely say that I have never been excited by some amazing magic to come from any of those oil bottles.

[80-85 husky]

have you sanded flat the first plate surface in the clutch basket? they were notoriously warped from the factory. we made up a ring with handles that we could lap in the clutch basket with 400 wet and dry. some of the baskets were only touching on half the plate surface giving a very grabby feel.

[tymes]

Is that advice for my shyt clutch? its graby as crap. The basket and hub arnt too bad.

Im trying to make my imagination see all that what you said but i cant, ill give it a look very shortly when i change the friction plates in Mrs KDX' bike, it will prob be clearer for me then.

Cant I just put it in the lathe and skim the friction surface flat.

[80-85 husky]

that will probably do it. Mr mc Hanic back in the day made a dummy first plate out of 1/4 inch steel with a couple of handles and stuck wet and dry to it and then worked it on the basket face to level it out. worked fine. fixed that grabbing beautifully.

I reckon spinning it up in a lathe would be more accurate and true than a hand held device.
