[QuadList] How to remove AVR2 pinch roller

[chill315 at aol.com]

It is fairly easy.  But you need a short Allen wrench.  (or a ball type Allen driver.)

Remove the two Allen screws holding the pinch roller and it's bracket from the pivot arm.

Replace the roller by removing the snap ring that holds the shaft that holds the roller.

Remove the bearings etc. that are inside the roller.

Reassemble.

Now when installing the roller assembly back on the pivot arm, it is critical that the roller be absolutely parallel to the capstan.  Slightly tighten the Allen screws and the pivot the arm toward the capstan.  Use a light to insure the face of the roller is parallel to the shaft.  Tighten the Allen screws.

Recheck the parallel again.  This is a critical adjustment to prevent tape damage.   During start and boost, the tape would be sent up or down in the path if this is not done.  Edge damage or wrinkling might result.
