T&T: Twin Disk Transmission oil

[Albin43SDtr]

Dave and All,

OOPS, I used the degree symbol in the temps and it came back as a 0. 
Sorry 'bout that. The correct numbers are:


>Twin Disc Manual is SM-179  # 1015924,
>Rev. 2 titled: Model MG-502 and MG-502-1 Service
>Manual (for) Marine Transmission Conventional, dated March 1982. It says:
>
>          Use API service class CD engine oils
>which is certified by the oil company to pass
>TO-2 or C-3 Test Specification. Also approved are
>SAE API service class CC engine oil and MIL-L-2104B.

I forgot that I could not use " ALT 0186 " ( 0186 typed in the 
numbers keypad with Num Lock on) to make a degree symbol in this 
forum. Again, sorry 'bout that.


Take care and be safe.
