Leveling Motor Base
(reference illustration on page 36)
1. Move motor base to lengthen or shorten the belt center distance, recheck alignment, then re-adjust the automatic
belt tensioner spring.
2.
Screw nut (1) down to compress spring (4) in ¼ inch over solid height.
NOTE: This measurement must be
taken before all spring coils touch.
3. Screw nut (3) down until it touches nut (1).
4.
Install new belts by rolling into position on the sheaves.
NOTE: The spring (4) will compress to allow belts
to cross into the grooves in the sheaves.
5. Raise motor platform arm by turning nut (3) until the slack has been removed from the belt.
6. Release spring (4) by turning nut (1) until the pin is at the midpoint location in the slot. Do not exceed the
recommended initial belt tension of 7.5 pounds deflection force for 3V section belts or 10 pounds deflection
force for 5V section belts.
7. Alternately adjust nut (3) then nut (1) until the belts are at the recommended tension and pin (5) is just above the
bottom of the slot. Assure motor base is level.
