I am about to refill both the transmission and differential of my 1928 D-60. The differential has new oil seals, but the transmission doesn't and has no provision for such. I'm afraid that the transmission will leak plenty if I use conventional 90 weight oil. I know that Ford model A transmissions are also without provision for oil seals, and hence Ford recommend 600 weight oil (so viscous it is almost grease). Would anyone know what is recommended for Durant's transmissions and differentials? or had any experience in this matter?

Thank you for the help!

Hi Claude-use 600 wt in both the trans and rear end. It will slow down the gears in the trans which makes it shift a little easier. It will also run out of the back of the trans slower! Phil

Hi Claude,
I have used these two oils for over 15 years, first in my model A Ford and then in both of my Durants.

They are used in the steering box, transmission, spring shackles and rear-end.

IMHO, both the Luriplate and Torco Oils are excellent modern replacments for the orginal steam cycleinder oil (600wt).

Thank you Phil and Rick for the smart advice. I will follow your recommendations and save my driveway, not to mention the underside of my Durant.

CHEERS!
