roller cage (2) carefully for cracks.
5. Inspect rollers (3). The rollers must slide up and down freely within the roller cage sliding surfaces A.
6. Without removing the garter spring,
inspect the coils for consistency. If
coils are distorted or uneven, cut the
oldspringwithasidecutter toremove
it, and replace it.
7. If garter spring replacement is necessary, it is very
important that the correct installation procedure
and special tool be used. Hold rollers in place on
roller cage with a light film of grease. Gently and
evenly roll the spring down the tapered tool (PN
2870888) and into the groove of the rollers and
cage. WARNING: If this procedureis notfollowed
thespringwillbeoverstressedandlose itstension.
Springs with incorrect tension may allow rollers to
move outward at high vehiclespeeds. If the rollers
move outward, the front hub(s) will engage and
cause vehicle instability, which could result in
serious injury or death.
W ARNING: Be sure to use correct garter spring.
These springs are very similar in appearance to those
used on earlier models. If the old, lighter springs were
installed on a machinerequiring theheavier spring, the
front wheels may engage at high speed, possibly re-
sulting in serious injury or death. Check springs be-
fore installation. Always verify the correct replace-
ment spring part number by referring to the
appropriate parts manual.
