High Temperature (Above 100°F): High-temperature stable lithium complex greases, synthetic base oil formulations, and enhanced oxidation resistance additives.
Community discussions reveal successful use of quality NLGI #2 lithium-based multi-purpose grease for general applications, marine-grade grease for enhanced water resistance, and EP (Extreme Pressure) rated greases for high-load applications. The key factor remains consistent application rather than premium grease selection.
Professional Application Techniques and Best Practices
Proper application technique significantly impacts lubrication effectiveness. Following professional methods ensures complete component protection while preventing over-lubrication that can damage seals and attract contaminants.
Step-by-Step Professional Process
- Clean the Fitting: Remove dirt and debris from grease zerk before attachment to prevent contamination
- Secure Connection: Ensure grease gun coupler locks firmly onto fitting for effective application
- Apply Gradually: Pump grease slowly until clean grease emerges from joint
- Work Component: Move component through full range of motion during greasing
- Final Application: Apply additional grease after movement to ensure complete coverage
- Clean Excess: Remove excess grease to prevent dirt accumulation and inspect operation
Professional service managers emphasize that customers following comprehensive greasing recommendations experience virtually no hydraulic or mechanical failures. The technique matters as much as the schedule – gradual application with proper pressure management prevents seal damage while ensuring complete component coverage.
Advanced Purging Techniques
Continue pumping until color change indicates fresh grease replacement. Work components through full range of motion during greasing to distribute lubricant thoroughly. Apply additional grease after movement to ensure complete coverage of all bearing surfaces and pivot points.
