When Sideboard Rubbers Are Left In Place
1. Adjust take up bearings evenly on both sides to
approximately. 30 lb/ft of torque.
2. Back off bolt 1/2 turn on both sides (approximately
1/16 inch).
3. Tighten jam nuts.
4. If torque wrench is not available, see section
“Adjust Conveyor Belt Tension” for steps to adjust
Belt tension
5. Sideboard rubbers must just touch belt. A gap will
allow asphalt to enter roller chain area. If sideboard
rubbers are pre-loaded against belt, rapid belt wear
will occur.
6.3.3.2 Adjust Scraper
Conveyor belt scraper is critical to belt wear. Scraper
mounts have rubber torsion springs inside so it will
spring out and back when splice comes around.
Scraper must be adjusted so that a sheet of paper just
slides between belt and scraper. However, if contact is
desired, adjust for absolute minimum contact pressure.
Scraper must be cleaned to remove accumulated
stones and grit at the end of each day while it is still
soft. This includes underside edge, which can act like
a cutting edge with stone buildup. The same is true
with the adjustable end gate seal.
6.3.3.3 Adjust End Gates
On discharge side, gate must be opened all the way. If
not, material ow is restricted and material slippage on
belt will increase. Material slippage on belt will result in
high belt wear.
6.3.3.4 End Of Day Clean Out
At the end of each day, inspect hopper and clean off
remaining paving material.
After asphalt usage, if a belt is left standing for a few
days, immediate start up will result in rapid belt wear. A
release agent prior to and after every use will lengthen
belt life.
Two recommended release agents are:
Zep slide (972) 228-3388
Tec shield (800) 700-2530
6.4 HydrAulIC system flusHInG proCedure
Whenever components such as, pumps, motors and
hoses are replaced on a closed loop system, the
loop must be ushed through a lter prior to start up.
Contamination due to previous component failure,
dirty assembly environment, and/or new hoses can
provide debris larger than maximum allowable size of
10 microns.
Whenever a pump or motor has failed, both pump and
motors in the loop must be replaced to eliminate source
of contamination. Pump and motors can be inspected
and rebuilt as necessary for reuse.
NOTICE
Prevent machine damage.
If a pump or motor failure has occurred.
Both pump and motors have to be replaced
to eliminate source of contamination.
Failure to do so can result in system
failure.
