Im tearing down a BW T-10, and can't seperate the main shaft from the main drive gear. I think this T-10 is from 1980 it has a 2:88 first gear. It appears that the back of the 3rd gear engaugement teeth are contacting the front edge of 3rd gear on the cluster. And it wont allow me to slide the whole mess out the back. Ive built a bunch of muncies and never had so much trouble, whats the trick? The front bearing is still in the case, it appears to be pressed onto the main drive gear pretty tight, does the bearing need to be removed first to allow more clearance to slide it apart. Please any suggestions from the transmission Guru's are appreciated-- Chicane?

67ragtp, This is a common problem tearing down a ST-10, either remove the front bearing to raise the main shaft over the top of the cluster gear, or remove the snap ring holding the midplate to the main shaft, remove the midplate, now remove the cluster pin out the back of the case, the cluster gear will drop to the bottom of the case and you can remove the main shaft. If the input is too tight I usually have to press the input out of the bearing ...Hope this helps...Crash

Thanks for the reply, I thought those were my two options. A couple of questions, if I drop the cluster to the bottom, does the cluster have a woodruff key holding it in, I have an old exploded veiw of a T-10. Not sure if the second design is the same. Does the cluster pin just push out the back? And during Reassembly will the main shaft go back in over the cluster when I put the cluster back in. Im guessing at that point I will have the main drive gear out and can put it in last. Lastly is there enough room to push the main drive gear through the front bearing if I Sit the case on my bearing press(shaft going through the slot in bearing press) and push the pilot down with the press? Thanks for the help!

67ragtp- The cluster pin is a press fit, but not that tight, I use a 1/2" brass drift and a 2lb. hammer and they come right out. Like an early T-10, the key you are talking about is at the back end and pops out when the pin comes out. With 2.43's and 2.64's you can put the complete assembled mainshaft in. With 2.88's, you have to put the input in the front of the case then mate to the mainshaft. After the complete mainshaft is in then you install the front bearing.
The cluster gear and pin are installed in the case first then the mainshaft assembly...Hope this helps...Crash
