Advice for tape drive repair / maintenance

Over the weekend, I got out two old DC-600 tape drives out of storage
- a Wangtek and an Archive. Only the Wangtek has a SCSI-to-QIC24
interface board, but I think I can use that on either drive (the board
may in fact be originally from the Archive drive anyways).
Anyways, after a quick visual inspection and wiping some dust off, I
did try it with an old DC-600 tape cartridge - one that I knew was not
important. It loaded OK and I started an attempt to image the tape to
About 1/4 into the tape something started vibrating, quickly
escalating and before I could do anything, the tape stopped. Result:
rubber goo on the plastic roller that drives the DC-600 cartridge
drive belt, some on the tape itself, and the tape shows deformation
(wavy) on the top half. I had to toss it.
The drive itself: the rubber roller driving the aforementioned plastic
roller had melted. Clearly visible is the area where the rubber meets
the cartridges' roller - the rubber is notched. Furthermore the
rubber roller is no longer cylindrical. Luckily there seems to be no
other damage to the drive - no rubber seems to have been deposited on
the R/W head.
Any idea what could have caused this and how to prevent it? I now
have two options: I can move the SCSI-to-QIC24 interface to the
Archive drive, but I want to make sure that the same doesn't happen
there. The other option is to remove the melted rubber roller and
steal the one from the Archive drive.
The mechanisms of the drives are different (the Archive has a lever
mechanism, whereas the Wangtek has a spring-loaded push mechanism) so
it's hard for me to tell if I can even move the rubber roller. Is
this maybe a component that can easily be obtained elsewhere?
