ADJUSTER AND RECOIL SPRING
CAUTION: Spring or rod may break if dropped
while handling, transporting or disassembling.
Nicks or weld craters in spring and rod
assembly can cause stress concentration
resulting in a weak spot. Weak spots may result
in immediate or eventual failure creating a risk
of personal injury. Put a heavy protective
covering around spring assembly when
handling, transporting, or disassembling track
adjuster.
A compression tool must be used for
disassembly and assembly because of the
extreme preload on spring.
CAUTION: The approximate weight of track
recoil spring disassembly and assembly tool is
225 kg (496 lb).
