Inspection
Inspect the spring for damage. Replace if neces-
sary.
Inspect shock for oil leakage. Place shock in ver-
tical position. Extend and compress the shock
several times over its entire stroke. Check that it
moves smoothly and with uniform resistance with
rod up. Any of the following conditions will denote
a defective shock:
– A skip or hang up when reversing stroke at mid
travel.
– Seizing or binding conditions except at extreme
end of either stroke.
– A gurgling noise after completing one full com-
pression and extension stroke.
Replace shock if any of these conditions are
found.
Assembly and Installation
For assembly and installation, reverse the disas-
sembly and removal procedures.
