coupling bolts per screw conveyor manufacturer’s
instructions. Install motor mount, motor, sheaves, belts
and guard. Refer to Appendix D for motor mount
installation instructions. Proceed to Step 15.
14. JR — When the torque arm turnbuckle is used for belt
tension adjustment, position the motor so that the belt pull
will be about 90° to a line through the drive high speed
shaft and hollow shaft as shown in Figure 13. For drives
where the motor is moved to adjust belt tension, mount
the motor slide base so that the belt tension adjustment is
approximately parallel to the belt centers. Refer to
Appendix D, for instructions relative to alignment of
sheaves and belts.
Lubrication
CAUTION: Drives shipped without oil.
15. JR, JF & JSC — Refer to Appendix A for selection of
lubricant. Refer to Table 9 at right for approximate oil
capacity of drives.
16. JR, JF & JSC — HORIZONTAL MOUNTING
Remove air vent and oil level plug (Refer to Step 1). Fill the
drive until oil shows in the oil level hole. Coat the air vent
and plug threads with #3 Permatex or equivalent thread
sealant before replacing.
JRV, JFV & JSCV — (VERTICAL MOUNTING) - Refer to
Figure 1, Step 1.
Input Shaft DOWN — Remove the fill plug and fill with
oil to level marked on the dipstick.
Input Shaft UP — Remove the oil level and fill plugs
and fill until oil shows in the oil level hole.
Coat the plug threads with #3 Permatex or equivalent
thread sealant before replacing.
17. JR, JF & JSC — Where applicable, pump grease into the
high speed shaft seal cover WITH A HAND GREASE
GUN, Figure 14, until fresh grease flows out along the
shaft. Wipe off excess grease from the shaft. DO NOT use
grease where it could contaminate the product e.g. foods,
drugs, etc.
Start Up
18. JR, JF & JSC — Before operating the drive, check any
fasteners, pipe plugs, air vent, etc. which may have been
loosened in the course of Outfitting, Installing and Lubricating
the drive, to be sure that they have been properly retightened.
If a long fastener was used to lift the drive into place, reinstall
the housing flange fastener and torque to the value shown in
Table 1. After one week of operation repeat check of all
external fasteners and pipe plugs.
19. AFTER ONE MONTH OF OPERATION:
a. Operate the drive until the sump oil reaches normal
operating temperature. Shut the drive down and
drain immediately.
b. Immediately flush the drive with an oil of the same type
and viscosity grade as the original charge (warmed to
approximately 100°F[38°C] in cold weather). Rapidly
pour or pump a charge equal to 25-100% of the initial
fill thru the drive, or until clean oil flows thru the drain.
c. Close the drain and refill the drive to the correct level
with new or reclaimed oil of the correct type and
viscosity. If determined to be in good condition by the
supplier, drain oil may be reused if it is filtered thru a
100 micron or finer filter.
