9.0 Care & Maintenance - [cont’d]
9.
Install hydraulic hoses.
9.7 Rubber Springs - Replacement
The rubber springs require periodic replacement.
Factors that shorten the longevity of the rubber
include abrasions, over-stretching and prolonged
operating cycles that build-up heat in the rubber.
Stopping the Ho-Pac during repositioning can help
minimize heat-aging.
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.
CAUTION
Some components of the Ho-Pac are heavy. Use
approved lifting equipment to properly support and
stabilize loads.
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 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, washers and nuts.
IMPORTANT
Flat washer must be installed on the “Rubber Side”
of mount. Refer to Figure 9-4.
7.
Tighten bolt to proper torque. Refer to Table 9.2.
Fig. 9-4 Flat Washer (3) must be placed against
“rubber side” (1) of Spring Mount
9.8 Threaded Fasteners – Replacement &
Preparation
IMPORTANT
All threaded fasteners must be checked frequently
for loose, broken or missing bolts. Keep threaded
fasteners tight. Replace with new if missing or
damaged. Replacement fasteners must be the same
type and grade. Follow proper tightening procedures
and bolt torque. Failure to follow these instructions
when tightening can have serious consequences.
x
A hardened washer must be used under the head
of a bolt in a blind hole.
x
With a nut and bolt combination, a hardened
washer must be used under the element to be
turned. AND the element not turned must be
prevented from rotating during tightening.
x
All threads must be free of damage and foreign
debris. Surfaces to be bolted must be flat.
x
Do not apply thread lock compound to the bolt
threads unless instructed to do so.
x
Lubricate bolt threads.
9.8.1 Bolts – Tightening Method, Pre-tensioning
and Torque
x
Install all bolts by hand until finger tight.
x
Bolts should be systematically tightened starting
from the most rigid part of the joint. Follow a
crisscross pattern (Ref Fig. 9-5)
x
Use progressive tightening of bolts. Turn each
bolt a little at a time until final torque is reached.
