What type of gear oil does the excavator use? Analysis of hot topics across the Internet and purchasing guide
Recently, hot topics in the field of construction machinery have focused on the care and maintenance of excavators, especially the selection of gear oil. Many users have questions about the model, performance and replacement cycle of excavator gear oil. This article will combine the hot content of the entire network in the past 10 days to provide you with a structured data guide to help you quickly understand the key points of selecting gear oil for excavators.
1. The role and importance of excavator gear oil
Gear oil is the "blood" of the excavator transmission system. Its main functions include lubricating gears, reducing wear, dissipating heat, and preventing rust. Improper selection may lead to reduced equipment efficiency, increased noise or even serious failure. Therefore, choosing the right type of gear oil is crucial.
2. Common models and applicable scenarios of excavator gear oil
According to popular discussions and industry standards across the Internet, the following are the commonly used gear oil models for excavators and their applicable scenarios:
| Gear oil model | Viscosity grade | Applicable temperature range | Recommended excavator brands |
|---|---|---|---|
| GL-5 80W-90 | High viscosity | -20℃ to 40℃ | Caterpillar, Komatsu |
| GL-5 85W-140 | Ultra high viscosity | -10℃ to 50℃ | Sany, XCMG |
| GL-4 75W-90 | medium viscosity | -30℃ to 30℃ | Hitachi, Kobelco |
3. How to choose gear oil according to working conditions?
1.High temperature environment: It is recommended to choose high viscosity gear oil (such as 85W-140) to ensure oil film stability at high temperatures.
2.low temperature environment: Choose low viscosity gear oil (such as 75W-90) to avoid difficulty in starting at low temperature.
3.Heavy load conditions: Priority is given to GL-5 grade gear oil, which has stronger extreme pressure resistance.
4. Answers to popular questions on the entire network
Q1: How often should the excavator gear oil be replaced?
According to the manufacturer's recommendations, it is usually replaced every 1000-2000 working hours or once a year, depending on the actual working conditions.
Q2: What are the consequences of mixing gear oil?
Mixing different types of gear oil may lead to additive failure, reduced lubrication performance, and serious damage to the gearbox.
5. Recent hot topics: gear oil brand recommendations
According to the popularity of discussions across the Internet, the following brands of gear oil are favored by users:
| brand | Featured products | User reviews |
|---|---|---|
| Shell | Spirax series | Excellent high temperature resistance |
| Mobil | Mobilube series | Good starting performance at low temperatures |
| Great Wall | Dewei series | High cost performance |
6. Summary
The selection of excavator gear oil needs to comprehensively consider the equipment model, working conditions and ambient temperature. This article organizes popular models, brands and frequently asked questions through structured data, hoping to provide a reference for your excavator maintenance.
