Dozer Chain CR5574 1156301 Fit For Caterpillar D7H D7R also compatible with LIEBHERR PR744

Common faults of dozer chains and their preventive measures are as follows:

Common Faults:

Wear: Prolonged use causes increased wear due to friction between the components of the chain.

Derailment: Improper tension of the chain or misalignment of the tracks can lead to derailment during operation.

Breakage: Improper tension, uneven wear, bent drive shafts, and excessive wear on sprockets can all lead to chain breakage.

Corrosion:Dozer Chains are prone to chemical corrosion in acidic, alkaline, or electrolyte environments, resulting in decreased strength and reduced fatigue life.

Track Skidding: Lateral forces from the track roller along the dozer chains can cause the inside or outside of the track to shift, leading to track skidding.

Preventive Measures:

Proper Tension Adjustment: Ensure that the dozer chains is properly tensioned to avoid excessive tension that increases pressure and friction, thereby reducing wear on the walking mechanism and preventing derailment.

Regular Inspection and Maintenance: Check the dozer chains tension monthly and adjust as necessary. New chains may stretch, so regular checks are essential to prevent loosening during operation.

Lubrication and Cleaning: Use high-quality original equipment chains and apply lubricant at the end of the season or when storing to keep the chain lubricated and extend its lifespan.

Timely Replacement of Worn Parts: Frequently inspect the dozer chains for wear and promptly repair or replace severely worn components, such as bushings, rollers, and chain pins.

Choose Appropriate Materials and Types: Select chain materials with good corrosion resistance based on the working environment, and understand their load limits and breakage testing limits.

Avoid Harsh Environments: Minimize exposure of the chain to acidic, alkaline, or electrolyte environments to reduce the risk of corrosion.

Straighten the Drive Shaft: Straighten bent drive shafts to ensure that the sprocket rotates within the allowable swing range, reducing the issue of sprocket misalignment caused by a bent drive shaft.
