Sony WM-EX610 Servicing
If you are planning to service the Sony WM-EX610, you will need the part numbers of some of the components. The replacement parts usually end up costing "mega-bucks" and it might work out cheaper to buy a working second-hand player for a fraction of the price on eBay.
Sony Part Numbers
- Drive Belt (F4)
- 3-220-035-01
- HP901 Playback Head
- 1-500-576-11
- Pinch Roller NA
- X-3377-362-1
- Pinch Roller RA
- X-3377-363-1
Torque Measurements
Of course, being a professional, I have a torque meter, and can therefore make repairs more accurately. Using the CQ-102D torque meter, I measured the torque parameters for the fast-forward (FF), and rewind (REW) tape functions. The values shown below are the recommended parameters.
- FWD
- 15 g/cm to 25 g/cm
- REW
- 0.3 g/cm to 1.5 g/cm
