Buying Guide
Choosing the right grease for your excavator can seem daunting, but here are a few key things to keep in mind:
- Operating Conditions: Consider the environment where your excavator operates. Is it wet, dusty, or subject to extreme temperatures? Choose a grease that’s designed to handle those conditions.
- Load and Pressure: If your excavator frequently handles heavy loads, opt for a grease with extreme pressure (EP) additives. Moly is also a great addition for high-load applications.
- Grease Compatibility: Make sure the new grease is compatible with the grease you’re currently using. Mixing incompatible greases can lead to performance issues. When in doubt, purge the old grease completely.
- NLGI Grade: NLGI (National Lubricating Grease Institute) grades indicate the consistency of the grease. NLGI 2 is a common choice for excavators, but consult your equipment manual for specific recommendations.
- Base Oil Viscosity: The viscosity of the base oil affects the grease’s ability to lubricate. Higher viscosity oils are generally better for high-load, low-speed applications.
FAQs
Here are some common questions about grease for excavators:
What type of grease should I use for my excavator?
The best type of grease depends on your excavator’s operating conditions and the manufacturer’s recommendations. Generally, a lithium-based grease with EP additives is a good starting point. For heavy-duty applications, consider a grease with moly.
How often should I grease my excavator?
Greasing frequency depends on usage and environmental factors. Consult your excavator’s manual for specific guidelines. As a general rule, grease critical points daily or every 8-10 hours of operation.
Can I mix different types of grease?
It’s generally not recommended to mix different types of grease. Incompatible greases can react and cause lubrication problems. If you’re switching to a new type of grease, purge the old grease completely.
What does EP mean in grease?
EP stands for “extreme pressure.” EP additives in grease help protect against wear under high loads and pressures.
Is it okay to use too much grease?
Yes, over-greasing can cause problems. Excess grease can attract dirt and debris, and it can also damage seals. Follow the manufacturer’s recommendations for the correct amount of grease.
Conclusion
Choosing the right grease for your excavator is crucial for maintaining its performance and extending its lifespan. Consider the operating conditions, load requirements, and manufacturer’s recommendations when making your decision. Whether you opt for the heavy-duty protection of Schaeffer’s 274 Moly Supreme Grease or the all-around performance of Lucas Oil Red ‘N’ Tacky, proper lubrication will keep your machine running smoothly.
