C1 transmission rebuild parts BW T-10

[Al R.]

Ordered a rebuild kit from Vol Vet and the metal 8 tooth speedometer drive gear from CC. The 8 tooth fits on the shaft correctly according to the trans shop, but the outer dia. of the gear is too big to work. Also, the owner informed me that the needle bearings were of a larger diameter that the originals and he can't fit all of them in. The last one just will not go in which leaves a space. Anyone encounted this problem, if so, how did you solve it? ALSO, where could original parts as these be purchased? I need to get this back on the road ASAP. Thanks!!! Al 1959 BW T-10 4 spd

Al, Are you sure that you received the right transmisson kit? The munice transmissons after 63 I believe had a bigger countershaft and the bearing sizes were bigger. The BW T10 had a smaller shaft and smaller needle bearings. These are the bearings your are refering to? or was it the input shaft bearings?(which are different between BW and Munice) There may have been a mix up in the packing. Did you call the vender?

As for the speedo drive gear I believe there are only two opitions, depending on the rear axle ratio.(308to 351 ratio and 373 to 456 ratio) Make sure that the drive gear is the correct one for your ratio and take a look at the plastic driven gear also, I believe the driven gear is on the C1 is a little different as it a little longer shaft.

I rebuilt the T-10 for my 1960. Ordered parts from D & L Transmissions. Had no problem with any of the parts. I order the complete rebuild kit plus new sliders and shifter forks. No problems with the needle bearings!

Re: C1 transmission rebuild parts BW T-10

Edward, the metal 8 tooth gear that the mech. took out was an 8 tooth. I wondered about this when I ordered a new one from C-Central as the only one offered is for the 3.08-3.54 as you stated. My rearend is a 3.70, the rep at CC said this was correct and would work when used with the 22 tooth green plastic gear. Also the needle bearings are for the counter shaft, not the big roller bearings on each end of the case. I didn't get home from work today in time to call Vol Vette on the rebuild kit. I will do so tomorrow AM. Hopefully it was a mixup. If not, I'll return the kit.

Donald, do you know if they carry the metal drive gears also? Also, do you have a contact # and name for them? If needed, you can PM or e-mail me at a.p.rains@att.net. Definitely, thanks for the info.. Al

I have used D&L a few times and they have been great. Very helpful when I had questions.

AL, click on the link that Donald put in his reply. Their phone number is at the top of their web page.
I usually speak with Larry who is very helpful and I'm sure can answer your questions.

The OD of the drive gear which is compatible with the green 22 tooth driven gear is 1.77". If you have a drive gear which is 1.85" OD, it will NOT work with the 22 tooth green driven gear.

Re: C1 transmission rebuild parts BW T-10

Joe, I'm not sure what the OD is. The shop owner did measure both the old metal gear and the new gear and told me by phone today that the new one was larger. I wasn't where I could write down the measurements. I can/will find out tomorrow. It's very frustrating on my end because I'm either in TN or when in NC I don't usually get home in time to get anything done about the car. (Good thing is I have job securiy). I don't always remember to carry all my books/written notes with me to work, so, it sometimes takes me several days to order parts or get the info together. Shop owner removed a green plastic gear with 22 teeth and a metal gear with 8 teeth both in need of replacement, per him, and not re-usable. KNOW WHERE I could find the different metal gears? Thanks Joe!!! Al

If the guy doing the work says the new gear is larger than the one he took out, I'm quite confident that you have the wrong one (i.e. the new one is 1.85" OD). The larger drive gear is the most commonly used but that does not include your application.

There are many sources for the gear. However, I would think that you could just return it to CC and get the correct one. The 1.77" and 1.85" are the only widely used drive gears. The same ones were used for both Muncie and T-10's. If, by chance, Corvette Central can't supply it, I'm sure that Larry Fischer at D&L can.

Re: C1 transmission rebuild parts BW T-10

Joe, I think at this point, I would rather return the parts to CC & Vol Vette and deal with D & L. Thanks!! Al

The good thing about dealing with D & L is you can talk to someone who know what they are talking about in Larry.

Re: C1 transmission rebuild parts BW T-10

your speedo gear problem might be that you have the long bullet and i don't think anyone makes the longer plastic stem now. cc used to make an an extension but i think they discontinued. i had to get the shorter stem plastic gear and cut the stem off another approx 3/4" long. then ground down a piece of key stock to the size of the square and pressed the 2 together. worked great. i think my gear was light green and the larger diameter for 3.70 gears but not sure.. i might have some pics and sketches if interested. note: if trans is in car it is easy to lose the plastic gear in there and you will never get it out but i think it can live in there peacefully.. jim o

Thanks to all who responded. I called Larry, who was going out the door on a 10 day vacation. He put me in touch with 1 of his comptetors who was able to help out.
