re: CR-3

Unfortunately the service manual isn't very helpful when it comes to the belts. Any additional help/hints would be very welcome.

re: CR-3

There are 2 belts. 1 for the 2 fly-wheels connected to the capstans. The other (smaller) belt connects to behind the left take up reel and then to another gear an inch to the left of that. To replace you need to remove the transport. It's easier if you disconnect a couple of the wiring harnesses from the main pcb near the transformer. You can remove the other ones if you want to completely take the transport away from the case, but you don't need to to get to the belts. There are also a couple of zip ties that hold on to those 2 wiring harnesses that you will need to cut or release to free up the transport enough to get it out of the case. Then you need to take off the motor housing from the back of the transport. I think it's 3 screws. Then you can put the new belt around the two flywheels and then onto the motor spindle and put the housing back on with the screws. The other belt is accesses from the front of the transport. there is a black metal piece that goes over the two take up reels. remove that with 2 screws and carefully move it to the side as its attached to a couple wires. then you can easily put the small belt around the two wheels on the left side, the right one being behind the left take up reel. Then put everything back together. And don't forget to but that ground wire screwed back to the case. Check out this vid. it's not a full tare-down (they make you pay for that) but in the first 5 minutes you can see enough info to tell you how to access these belts. https://youtu.be/y_toWB_mbOU
