How to Replace the Idler on John Deere 17D 17G 17ZTS?

To replace the idler, you need to loosen the track tension, remove the old assembly, and install the new 9312918. This can be done in 2-4 hours with basic tools, and no spring removal is necessary.

1. Park the machine on level ground.

2. Release the grease from the adjuster cylinder to loosen the track.

3. Disconnect the track at the master link.

4. Remove the idler assembly by unbolting the main bolts (usually four).

5. Clean the frame mounts.

6. Install the new AFT Parts 9312918 idler, ensuring it is torqued to 100 ft-lbs.

7. Reassemble the track and pump grease to achieve a 1.5-inch sag.

8. Test the machine in low gear.

Steps to follow in Alberta's environment:

• Safety: Always chock the machine and disconnect the battery.

• Tools: Wrenches, grease gun, pry bar.

• Pro Tip: Align bushings precisely to avoid binding.

AFT Parts assemblies arrive pre-greased, saving valuable time during installation.

Why Do Idlers Fail on These John Deere Mini Excavators?

Idlers can fail due to contamination, overload, improper track tension, or impacts, with failure typically occurring within 6-12 months of heavy use. Alberta's harsh conditions, including dusty and rocky terrain, can exacerbate wear.

Idlers wear out when dust enters seals, preventing proper lubrication of the bearings. Over-tightened tracks cause excessive strain on the idler flanges, while loose tracks result in dry spinning idlers. In Alberta, rocky soil conditions can chip the rims and misalign the tracks. These issues accelerate wear on the sprockets, leading to costly repairs. AFT Parts counteracts this with triple-lip seals and hardened steel components that endure Alberta's demanding environment.

The most common failure factors include:

• Contaminated grease

• Improper track sag (ideal: 1-2 inches)

• High wear without regular rebuilds

AFT Parts offers solutions that extend the interval between replacements by up to 20%.

What Signs Indicate Idler Replacement Time?

You should replace the idler when flanges wear more than 1/4 inch, there is excessive play, or you notice unusual noise or uneven track wear. Regular checks help prevent costly repairs by identifying issues early.

Signs that it's time to replace the idler include:

• Cupped flanges

• Discoloration (blueing from heat)

• Leaking grease

• Excessive side play (>3mm)

• Vibrations transmitting to the cab

In Alberta, where equipment faces extreme conditions, AFT Parts diagnostics help contractors avoid costly breakdowns. Take baseline photos to track wear trends over time.

Inspection checklist:

• Flange depth: minimum 0.75 inches

• Bearing spin: smooth and cool

• Track alignment: centered

With AFT Parts, you restore precision to your equipment's undercarriage.
