CONSIDERATIONS WHEN SHAFT TAPER EXTENDS INTO CUTTER MOUNTING AREA

IDEAL INSTALLATION POSITION
Diagram "A" shows a straight shaft under an area where cutter is to be mounted. This will assure full clamping of cutter onto shaft.

ACCEPTABLE INSTALLATION POSITION
Diagram "B" shows part of the shaft taper under the cutter. As you can see, this allows approx, 3/4 of cutter width clamped on straight shaft; however, it gives adequate holding power for cutter.

IMPOSSIBLE INSTALLATION**
Diagram "C" - Do not attempt this installation. Cutter cannot clamp on a full taper. The cutter follows the taper and causes loosening and spinning on the shaft.

It is impossible to clamp a cylinder onto a cone.

 

* ALLOW MINIMUM OF 3/16" BETWEEN STRUT AND LINE CUTTER FOR END PLAY AND WATER FLOW. (WHEN THERE IS EXCESSIVE END PLAY OR LOOSE MOTOR MOUNTS, ALLOW MORE SPACE ACCORDINGLY.)

**NOTE: WHEN FULL TAPER IS IN THE SPACE WHERE THE CUTTER IS TO BE INSTALLED, THERE ARE OTHER OPTIONS: (1) CUT A RING FROM STRUT BOSS OR (2) INSTALL A "SPURS" SPACER BETWEEN TRANSMISSION AND SHAFT FLANGES. (REFER TO SPECIAL CONDITIONS).
