9.0 Care and Maintenance – [cont’d]
CAUTION
Some components of the Ho-Pac are heavy. Use
approved lifting equipment to properly support and
stabilize loads.
CAUTION
Crush injury. Do not place hands or
fingers between mounting frame and
compaction plate during removal of
spring mounts.
Ensure all loads are adequately supported before
performing any service work.
NOTE:
If multiple mounts are to be replaced, it is
recommended to replace one mount at a time.
1.
Position Ho-Pac on flat, stable surface.
2.
Support top mounting frame to remove weight
from mounts.
3.
Loosen all nuts. Remove nuts and washers.
4.
Remove all bolts and mount.
5.
Position new mount. Use alignment bar to align
bolt holes.
6.
Install new bolts, flat washer and nuts.
IMPORTANT
The flat washer must be located on the “Rubber
Side” of mount as shown in Fig. 9-1.
7.
Tighten bolt to proper torque. Refer to Table 9.2.
9.9 Threaded Fasteners Tightening Torque
Due to vibration and shock loads experienced by the
Ho-Pac, all threaded fasteners must be checked
frequently for loose, broken or missing bolts.
IMPORTANT
Keep fasteners tight. Replace missing or damaged
fasteners with new. Replacement fasteners must be
the same type and grade. Follow proper torque
procedures. Refer to Table 9.2 for bolt torque.

9.9.1 Bolts - Proper Preparation, Pre-tensioning
and Torque
1.
Clean threaded fasteners and surfaces to be
bolted.
2.
Lightly lubricate threads.
IMPORTANT
Do not apply thread lock compound to the bolt
threads unless instructed to do so.
1.
Install all bolts finger tight.
2.
Follow a crisscross pattern (Fig. 9-3) and tighten
all bolts until 1/3 of the specified torque in Table
9.2 is reached.
3.
Tighten all bolts again until 2/3 of the specified
torque is reached.
4.
Continue crisscross pattern and tighten to the full
torque shown in Table 9.2.
