Tranny Flush Question

Thu Nov 14, 2013 7:46 am

This applies to my H, but could be relevant to any Cub.

We often read/hear to drain out the old tranny case then flush with kerosene. Would old gasoline be a suitable substitute for kerosene? Other than the service manual's direction, is there any reason not to use old gas?

Reason for question: I have plenty of old gas on hand and very little kerosene left.

Thanks.

I think that safety would be my biggest concern. I also think that gasoline would be much more harmful to oil seals. I know kerosene has gotten pretty expensive, maybe diesel fuel would be a bit less expensive.

Off road diesel would be my choice. My F-12 transmission and steering gear has been full now for almost two weeks.

H transmission capacity is 24 quarts (6 gallons). they will hold more, but that is what they are supposed to have in them.
