To remove the Bypass idler rollers:
1. Lift the retaining spring [1] over the end of the idler roller shaft.
Figure 4.15 Releasing Idler Roller Retaining Spring.
2. Pull the released shaft end out of the bushing fork [2], releasing the opposite
end of the shaft from the other retaining spring.
3. To install idler roller assemblies reverse the steps.
Installation Note:
•
Make sure the flat surface of the bushing aligns in the fork.
•
Rollers are non-directional so it does not matter which end goes in each fork.
•
After the assembly is in place, gently pull the assembly outward and release
to ensure it moves freely in the fork.
