I changed my 1949 F1 3 speed to a 4 speed with reverse lockout.It has a T8C-1 stamped on the side.Does anybody know which seal it takes on the tail shaft (the transmission support)?I also need the part number for the pinion shaft seal on the differential,if any one knows it.
The only 4-sp available would be the crashbox spur-gear 4-sp, which is the Warner T9. I believe the rear seal is C1TT-4813-C. Can't swear to it, the parts CD is unclear.
olbiker, please write down T9 somewhere, the T8C case markings are irrelevant. Originally your trans would have a painted "4TB" on it, probably gone now. Warner T9 is what will get you what you need.

I'm not using the CD, have the original bound paper 1948/56 truck catalog the CD was scanned from (final printing 1964).
There are two parts lists for the T9 (5 & 6). Same seal listed in both of them.
C1TT-4813-C .. Output Shaft Oil Seal / 2.12" I.D. x 3.065 O.D x 1/2" thick / 1948/52 T9 / Obsolete

GREEN SALES CO. in Cincinnati OH has 6 = 800-543-4959 (and 5 - B6A-4676-A = see post 2).

THANKS again! I went to an industrial supply house and matched up the seals. Getting closer and closer. Guess this time something finally went right. Now, to find a clutch engagement shaft....
