Maytag washer LAT9605 AAE won't spin

The washer fills agitates and drains well on all cycles but will not spin in the spin cycle and can smell rubber burning possibly from the belt. I have checked between the walls of the tubs for jams and found nothing. The tub rotates when I rotate the transmissionn housing.I opened the cover of the orbital transmission, drained the oil and looked to see if there was something broken and found nothing. My attempts to get maytag manual to understand mechanism were futile since there is nothing available on maytag, although I was able to get diagrams of the parts on the internet. I would be grateful if you could enlighten me and help me troubleshoot the problem.

I thank you in anticipation.

I have a legacy washer and it does not move on the spin cycle. I checked the belt and oulley system and found a black plastic pulley tensioner had fallen off it;s shaft and the belt was very loose. Re-installing the pulley so the belt is very tight solved the problem. I’m not what caused it to fall off initially and it may do so again
