With key in place, position the fan on the input shaft to the
determined “NA” distance.
Locate the set screw which is 90° from the keyway to the
spotting hole on the shaft.
Tighten set screws (2). Reference Table 17, (Page 28) for
torque requirements.
6.7.3 REMOTE GREASE LINE
INSTALLATION
NOTE
: ALL EXTERNAL PLUMBING (PIPE NIPPLE, PIPE
PLUGS, FITTINGS) ARE STANDARD NPT (NATIONAL PIPE
THREAD) CONNECTIONS.
Per preceding drawing, install grease fitting hardware
(Items 1 & 2) at seal carrier (if not already installed), and
fill grease tube (Item 5). Note, fill grease tube prior to
installation.
Assemble grease fitting hardware (items 1, 3, & 4) into
predrilled 7/16” (11 mm) diameter hole in fan shroud (if not
already installed).
The grease line (item 5) will be inserted into the grease
fitting hardware in the fan shroud when the shroud is
assembled to the speed reducer.
6.7.4 FAN SHROUD INSTALLATION
Position the fan shroud so that it fits tight over the shroud
clips. Check to insure that when the input shaft is rotated,
the fan does not interfere with the shroud. Gently bend the
shroud clips to position the shroud.
NOTE
: The fan shroud should be pre-drilled for the shroud
clips and the remote grease line (RGL).
Insert RGL grease tube into shroud grease fitting
hardware.
Using bolts and washers that were removed originally
during disassembly, fasten the shroud to the shroud clips.
Once fastened rotate input shaft to insure no interference
with fan.
