Idler Shaft Inspection
Maintenance Schedule - Inspect every 30 hours of vehicle operation
Damage to the idler shaft and sprockets can result from loose idler chains or
sprocket misalignment. Please inspect regularly.
1. Perform the servicing procedure, Removing the Firewall in section VB.
2. Inspect the sprockets on the idler shaft thoroughly for:
ξ cracks in the casting
ξ worn, broken or missing teeth
If any of these conditions are noted, replace the idler shaft (Vanguard or Vanguard 2
models) and/or the floating sprocket (Conquest, Bigfoot, Response or 6x6 Conquest
models) immediately.
IMPORTANT
If any wear is noted on the idler shaft or itβs components, it is advisable to check the
brake disc drive sprocket as well to ensure that the misalignment has not caused any
damage to this drive component either.
When ordering a replacement idler shaft assembly, please note that different ARGO
models use different idler assemblies. Refer to the correct parts manual to ensure the
correct replacement part.
