Why Does Idler CA935 Wear Out Fast?
Idler CA935 experiences wear from dirt, overload, misalignment, and abrasive materials found on Alberta sites. Unlubricated bearings seize, increasing track and sprocket damage, while overloading accelerates bushing wear.

Heat-treated components also resist thermal expansion and freeze-thaw stresses, ensuring reliable operation in harsh conditions.
How to Install Idler CA935 Correctly?
To install an Idler CA935, first release track tension and support the undercarriage. Remove the old idler, align the new AFT Parts unit with frame mounts, and torque bolts to 120-150 ft-lbs. Reconnect any hydraulic lines and tension tracks according to manufacturer specifications, typically 2-inch sag. Test under load to verify smooth operation. Installation is straightforward with basic tools and usually requires 1-2 hours.
What Are Idler CA935 Maintenance Tips?
Inspect Idler CA935 monthly, checking seals, bearings, and flange wear. Grease weekly with high-temperature lithium grease suitable for Alberta's winters. Keep debris off the idler to prevent seal breaches. Pair with AFT Parts track rollers to balance undercarriage wear. Track hours via ECM, and replace proactively around 1,500 hours for maximum longevity and cost savings.
How to Choose Quality Idler CA935?
