Akai x-150D Rewind Problem

Wont rewind with heavy tape reel. Took top off, while in rewind mode, motor spins,in turn spins aprox 2 inch diameter rubber wheel which in turn spins knurled wheel on bottom of reel drive. All turning fine. Part that holds the tape doesnt turn. Seems there is some kind of friction clutch that maybe is too loose. Any ideas? The take up braking force also seems a little too tight making it pull hard.

I don't know if this will help, but here is the troubleshooting guide and rewind operation description from the SM.

Here is a video of how the transport REW works. Watch starting at 02:18. Make sure that your wheels are all moving correctly. The other thing that he mentions for the supply hub is a hub friction pad, maybe that is bad or needs cleaning/adjusting. Also, make sure that the supply hub brake is working correctly and releasing on REW.
 
Thanks for the reply. I looked a little harder and could see the second drive wheel (D) from the rewind motor,with the knurling was slipping on the rubber "tire" on the tape pulley (G). Probably need a new "tire" or large o-ring.
 
Thanks again for the useful information. Using the troubleshooting flow chart I guess I need to replace the "reel".
 
Before replacing, try to disassemble it and clean the felt ring pad and see if it provides more friction to the hub.
 
Well, for people who might be watching this thread, it turns out a piece of diecast metal broke off the rewind/fastforward switch. The piece is supposed to take the reel brakes off during rewind and FF. The piece can be seen on the top diagram just northwest of the letter A. I found this after seeing fragments in the tape case. Im sure this piece is made of "unobtainium". Ill see if I can jerryrig something that will work.
 
I did some research and it seems ALL diecast control cams in old Akai RRs are doomed to fail at some point. The potmetal oxidizes and disintegrates. A company called Reel Pro Sound Guys manufactures a 5 piece redesigned cam kit for $79 dollars. So now Im debating to buy or not.
