The Case 850C Crawler Dozer, like all heavy machinery, is equipped with various systems that rely on high-quality fluids to function correctly. These fluids act as lubricants, coolants, and cleaners for vital components such as the engine, hydraulic system, and transmission. Without regular fluid changes, contaminants like dirt, metal shavings, and moisture can cause premature wear, overheating, and even complete system failures.
Here are some of the critical reasons why fluid changes are essential for the Case 850C:
- Lubrication: Fluids help lubricate moving parts within the engine and transmission, reducing friction and wear. Over time, fluids degrade, and their lubricating properties diminish, leading to increased wear on components.
- Cooling: Fluids absorb and dissipate heat generated by the engine and hydraulic system. If the fluid is not changed regularly, it may lose its ability to cool these components, leading to overheating and potential damage.
- Contaminant Removal: Fluids also help clean internal components by carrying away debris, dirt, and contaminants that naturally accumulate. If left unchanged, these contaminants can cause blockages and damage vital parts.
- Efficiency: Fresh fluids maintain the efficiency of the system. Old or degraded fluids can reduce performance and fuel efficiency, making the machine work harder than necessary.
The Case 850C is equipped with several critical fluid systems, each serving different purposes. These include:
1. Engine Oil
