Repair
This machine uses an “enhanced” MDM7-series drive, the MDM-7X2A. The CXD2662 DSP/ATRAC chip is clocked at 90.3168MHz (as opposed to 45.1584MHz in “normal” Type-R/MDLP machines using MDM7-series drives) in order to support the processing required for the 2x and 4x digital copies from the internal CD drive. This means if you have an MD drive fault, you can't just swap in an MDM7A from say an MDS-JE440. In addition, the usual 23-way ribbon is only 17-way (both still have the same 27-way ribbon too).
Since this is an MDM7-series drive, the same 17×0.8mm square load belt is used and probably needs replacing - see Sony MDM7-drive belt replacement. The CD drive also uses a rubber loading belt - this is approx 32mm diameter (114mm circumference) and 1.5mm square.
