Bobcat Track Loaders and Excavators: Track Tension

Adjusting track tension is an essential maintenance task – and the good news is, it’s something you can typically handle on your own.

Proper track tension is crucial for the optimal performance and longevity of your Bobcat machine. You’ll want to ensure the tracks are correctly tensioned to prevent unnecessary wear and tear, improve efficiency, and reduce the risk of damage.

In particular, new tracks will stretch – so if you have a new machine, keep an eye on tension for the first 100 hours.

The processes described below are the same for compact track loaders and excavators. They apply to both older and current models.

Here’s what you need to know about track tension - including signs of incorrect tension, how to check track tension, and how to adjust it.

Signs of Incorrect Track Tension

Recognizing the signs of incorrect track tension can help you address issues before they cause significant problems. Watch out for the following indicators:

1. Excessive track wear: Uneven or rapid wear on the tracks can indicate improper tension.
2. Track slippage: If the tracks slip or derail frequently, they may be too loose.
3. Noise and vibration: Unusual noises or vibrations during operation can be a sign of either too loose or too tight tracks.
4. Poor traction: Difficulty in maneuvering or reduced traction can result from incorrect track tension.

How to Check Track Tension

Checking the track tension on your Bobcat excavator or compact track loader is a straightforward process.

1. Park the machine on a flat surface and turn off the engine.
2. Raise the tracks: For loaders, lift the loader arms and secure them with the safety support device. This ensures the tracks are off the ground and not under load.
3. Measure track sag: Use a straightedge to measure the sag in the track between the drive sprocket and the front idler. The recommended sag is specified in the operator’s manual (typically between 1/2 inch to 5/8 inch). Be sure not to put your finger in the pinch points between the track and the roller.
4. Compare measurements: Compare your measurement to the recommended specifications in the manual. If the sag is outside the recommended range, the tension needs adjustment.

How to Adjust Track Tension

Follow these steps to ensure your tracks are correctly tensioned. You’ll need a wrench set, a grease gun, and your Bobcat operator manual.

1. Locate the tensioning point: Find the tension adjustment fitting, located in the middle of the track frame.
2. Adjust tension:
   • To increase tension, use the grease gun to add grease to the tensioning cylinder. This will push the front idler forward and increase track tension.
   • To decrease tension, loosen the bleed valve on the tensioning cylinder to release grease and reduce tension.
3. Recheck track sag: After adjusting, measure the track sag again to ensure it falls within the recommended range.
4. Secure adjustments: Tighten any loosened fittings and ensure the tensioning components are secure.

Maintenance Tips for Track Tension

To maintain proper track tension and ensure the longevity of your Bobcat loader or excavator:

1. Regular inspections: Check track tension regularly, especially after operating on rough or uneven terrain.
2. Clean tracks: Remove debris and mud from the tracks and undercarriage to prevent uneven wear and tension issues.
3. Monitor track condition: Keep an eye on the overall condition of the tracks and replace them when they show significant wear.

Your Bobcat operator’s manual has specific recommendations as well as instructive images related to track tension and maintenance.
