1. For tightening motor V-belt on
rigid
base plate, remove
appropriate quantity of shims (Item No. 324A) under
the motor until the desired total flex of the V-belt is
approximately ½”.
1. For tightening motor V-belt on
floating
adjustable motor
mounting plates (Item No. 16015-10 or 16015-11), loosen
the upper wing nuts (Item No. 16015-3). Then loosen the
bottom wing nuts (Item No. 16015-3) which are located
under the mounting plate. This enables the motor
mounting plate to drop to the desired belt tension.
Re-tighten the upper wing nuts evenly so that the motor
stays horizontal. Do not tighten belt to extremes. This will
cause undue pressure on and premature failure of the
motor bearings.
ADJUSTMENTS
C. MOTOR ADJUSTMENT:
Starting with Serial Number 27958 three (3) phase Model 3334’s will no longer be equipped with an
adjustable motor base plate, Item No. 16015-10 and 16015-11. The motor will be bolted to the bottom of the
base structure and V-belt tension adjusted utilizing shims.
This change has evolved as a result of the market demand for higher blade speeds. The revised mounting
procedure will insure a more rigid motor installation creating positive belt alignment and minimizing machine
vibration.
The base bottom has been redesigned to accept the frame sizes of the current 3 phase motors. Units prior to
Serial Number 27958 can be retrofitted by ordering Item No. 16015-12 motor base plate and template (flat),
and 36 pieces Item No. 324A motor shims.
