V-BELT CARE CONT...
Check the alignment of the sheaves. The drive and driven shafts should be parallel both horizon-
tally and vertically, and the centers of both sheaves should be in a straight line. Although V-belts
can tolerate minor misalignment (About 1/16 inch per 12 inches of shaft center distance), close-
to-perfect alignment will prolong belt life.
Set the belt take-up adjustment at its minimum position and place the new belt in the correct
position by hand. Never pry belts over the sheave with a screwdriver or other hard object.
All V-belt drives must operate with correct belt tension to provide the optimum wedging action of
the belt against the groove sidewalls. Allow a reasonable break in period of a few hours, and
then check for proper belt tension. New belts tend to elongate slightly until they are seated in the
sheave groove and initial stretch is removed from the belt. Be sure to reinstall all protective
guards and shields.
CUTTER HUB:
REMOVING THE CUTTER HUB:
Should it ever be necessary to remove the cutter hub, remove the three (3) cap
screws and insert two (2) 1/4" - 20 cap screws into the threaded holes in the
bushing flange. Tighten the cap screws alternately and evenly so the press against
the shoulder of the cutter hub, "jacking" the bushing from the hub.
INSTALLING THE CUTTER HUB:
To install the cutter hub, assemble the bushing into the cutter hub so that the three
(3) counter-bored holes in the bushing line up with the three (3) threaded holes in
the cutter hub. Insert the three (3) cap screws through the counter-bored holes into
the threaded holes and screw them in finger tight. Slide the cutter hub and bushing
on the shaft over the key. Locate the assembly so the blades will clear the base
and the guard. Tighten the cap screws in sequence around the circle. Repeat until
no further movement can be obtained (approx. 12 ft. lbs.).
BEARINGS:
The nylon bearing (clear collar) must be inserted in the blade with a slight inward bulge. After
locating the bearing in the collar of the blade, press the bulge to conform to the contour of the
cutter hub.
