INSTALLING SPARE WHEEL AND TIRE ON CARRIER (M915, M916, AND M915A1)
WARNING
Exercise caution when raising or lowering spare wheel and
tire assembly. All personnel must stand clear during lifting
operations. Should wheel and tire assembly fall over or drop
from lift, serious injury to personnel may result. Failure to
comply may result in injury to personnel. Seek medical
attention in the event of an injury.
Do not touch hot clutch disc when raising or lowering spare
wheel and tire assembly winch brake. Failure to comply may
result in injury to personnel. Seek medical attention in the
event of an injury.
Ensure winch cable drum has a minimum of four full turns
of cable prior to lifting spare wheel and tire assembly.
Failure to comply may result in cable pulling off cable drum
and injury to personnel or damage to equipment. Seek
medical attention in the event of an injury.
CAUTION
If winch brake disc shows signs of overheating, stop and
allow 15 minutes for winch brake disc to cool down.
NOTE
The winch automatically brakes when pressure is taken off
handle regardless of which direction it is being turned. If
slack is needed to secure cable around wheel and tire
assembly, you must pull on cable and turn the handle in a
counterclockwise direction at same time. Do not pull out
more cable than needed.
1. Install winch cable (Figure 8, Item 1) through wheel opening (Figure 8, Item 4),
wrap it around wheel and tire assembly (Figure 8, Item 3), and secure snap hook
(Figure 8, Item 5) back on winch cable (Figure 8, Item 1).
2. Take up slack in winch cable (Figure 8, Item 1) by turning winch handle
(Figure 8, Item 2) in clockwise direction.
NOTE
This step requires two personnel.
3. Turn winch handle (Figure 9, Item 2) clockwise to install wheel and tire assembly
(Figure 9, Item 1) on spare tire carrier side panel (Figure 9, Item 4) while guiding
