YES

Replace capstan motor.

4-ii) Unusual sound in FF/REW mode

Is reel disk height as specified ?

Thrust gap found at reel disk ?

Drive system out of contact with any

part on main PWB ?

Turn capstan motor by hand.

Unusual sound heard ?

Check drive system’s gears for

damage. Replace damaged gear

with new one.

• Reel disk

• Limiter pulley ass’y

• Idler wheel ass’y

Check reel disk and main chassis.

And replace defective parts.

Adjust reel disk height.

Rearrange the parts on main PWB.
