Introduction to Extendahoe Buckets
Extendahoe buckets are specialized attachments for backhoes and excavators, designed to extend the reach of the bucket. Developed in the late 1980s, they allow operators to dig deeper trenches or reach over obstacles without repositioning the machine. Popular among contractors and municipal operators, these attachments are compatible with brands such as Case, John Deere, and Caterpillar. The Extendahoe system typically includes a telescoping inner section mounted on the bucket end, supported by nylon sliders that guide movement along the stick. Proper lubrication of these sliders is essential to reduce friction, prevent wear, and minimize operational noise.
Lubrication Challenges
Nylon sliders can produce squeaking noises when operated without lubrication, especially in dusty or abrasive environments. Unlike steel-on-steel components, nylon-on-metal contacts require careful choice of lubricant to avoid attracting dirt or creating abrasive paste, which accelerates wear. In older Extendahoe designs, the inner section of the telescoping assembly sits on the stick end, exposing sliders to dust and debris.
Lubrication Options
Several types of lubrication have proven effective for Extendahoe sliders:
Application Recommendations
Maintenance Tips and Real-World Experience
Operators have reported significant reduction in squeaking and smoother bucket operation when switching from grease to spray-on graphite. One contractor in Utah noted that using the Napa dry film lubricant prevented dirt buildup, improving slider lifespan by several months. Another operator preferred moly grease, especially when digging in heavy clay, as it provided superior wear resistance. Regardless of lubricant type, consistent maintenance is critical for preventing premature wear of the telescoping mechanism.
Conclusion
Proper lubrication of Extendahoe sliders enhances performance, reduces noise, and extends the life of the telescoping assembly. Both dry film lubricants and moly greases are viable options, each suited to different operating conditions. Routine cleaning and careful application prevent dirt adhesion and maintain smooth operation. Contractors using Extendahoes should develop a simple maintenance schedule incorporating these lubrication practices to maximize efficiency and reduce repair costs over time.

Lubrication Options
Several types of lubrication have proven effective for Extendahoe sliders:
- Graphite Dry Film Lubricant
- Leaves a dry, black film on the sliders
- Minimizes dirt accumulation
- Commercially available from Caterpillar and automotive suppliers such as Napa
- Also referred to as DFL (Dry Film Lubricant)
- Leaves a dry, black film on the sliders
- Molybdenum Disulfide Grease (Moly Grease)
- Provides high-pressure protection and reduces friction
- Works well in abrasive conditions but may attract dust if over-applied
- Commonly used on pins and bushings in heavy equipment
- Provides high-pressure protection and reduces friction
- Standard Equipment Grease
- Some operators apply the same lithium or multi-purpose grease used on pins
- Ensures smooth sliding but requires periodic cleaning to prevent buildup
- Some operators apply the same lithium or multi-purpose grease used on pins
Application Recommendations
- Frequency: Lubricate sliders at least once a month or after heavy use in dusty environments.
- Quantity: Apply a thin, even coat; avoid over-lubrication which can attract dirt.
- Cleaning: Wipe sliders before applying lubricant to remove dust and old residue.
- Environmental Consideration: Use dry film lubricants when operating in sandy or muddy conditions to reduce debris adhesion.
