4.7 cutter eccentric drive Belts
The drive belts that connect the hydraulic drive
motor to the eccentric are carbon fiber industrial
belts that are designed for high horsepower appli-
cations. They are matched to grooved pulleys and
have very little stretch. Therefore, they typically
don’t need to be adjusted often and proper belt
tension is extremely important when adjustment
is required. The belts are strong enough to cause
severe damage to bearings, shafts and other com-
ponents if they are set too tight. Additionally, if a
belt is too loose, it can ride on top of the grooves
in the pulleys and become too tight.
Make sure you follow the instructions and set the
tension to proper specifications when adjusting
the drive belts. Never overtighten them.
WARNING
OVERTIGHTENED DRIVE BELTS CAN CAUSE SEVERE
DAMAGE TO PULLEYS, SHAFTS AND BEARINGS IF THEY ARE
ADJUSTED TOO TIGHT OR MISALIGNED. ALWAYS MAKE
SURE THE BELTS ARE PROPERLY ALIGNED AND SET TO THE
MANUFACTURES SPECIFICATIONS WHEN THEY REQUIRE
ADJUSTMENT AND NEVER OVERTIGHTEN THE BELTS.
Before performing any maintenance procedure,
make sure the cutting system is shutdown with
the truck in the service position.
Drive Belt Inspection and Maintenance
Daily:
• The belts must be inspected before each shift
for damage, tension and alignment.
• Inspect pulleys frequently during operation
for the accumulation of impacted material
that will increase belt tension which will stress
the bearings and break the shaft. Clean out
material as required.
Monthly/200 Maintenance:
• Check drive belt tension, pulleys and belt align -
ment. Adjust or replace as required.
• Check and grease drive pulley pillow block
bearings and idler pulleys.
