4. Chassis and Suspension

• The chassis of the Case 90XT provides the frame on which all other components are mounted. The suspension system is responsible for ensuring stability and comfort while operating the machine on rough terrain. Over time, the suspension components, such as shocks and bushings, may wear out, leading to decreased performance.
  
• Common Replacement Parts:
  • Shock absorbers
    
  • Bushings and bearings
    
  • Frame components (e.g., skid plates, brackets)
    
  • Steering linkage parts
    
• Importance of Regular Maintenance: Inspecting the chassis and suspension system for cracks, wear, and rust ensures that the loader can continue to function without compromising operator safety or machine stability.
  

5. Electrical System

• The electrical system in the Case 90XT controls various functions such as lighting, diagnostics, and the starting system. Components like the alternator, battery, wiring, and fuses play vital roles in ensuring that the machine operates as intended.
  
• Common Replacement Parts:
  • Battery
    
  • Alternator
    
  • Fuses and relays
    
  • Wiring harnesses
    
  • Electrical connectors
    
• Importance of Regular Maintenance: Regularly checking the battery charge, cleaning battery terminals, and inspecting the wiring for damage or corrosion can help avoid electrical issues. Replacing worn fuses and relays prevents electrical system failure.
  

Sourcing Case 90XT Parts
When it comes to sourcing parts for the Case 90XT, there are several options available, but it is important to choose reliable suppliers to ensure the quality and longevity of the machine. Using OEM (Original Equipment Manufacturer) parts is often the best choice for ensuring compatibility and performance. However, there are also high-quality aftermarket options that can offer cost savings while still meeting the required specifications.
1. OEM Parts

• OEM parts are parts that are made by the original manufacturer (Case) or authorized manufacturers. These parts are designed specifically for the Case 90XT, ensuring a perfect fit and function.
  
• Pros:
  • Guaranteed quality and compatibility
    
  • Full warranty support
    
  • Ensures the longevity of the machine
    
• Cons:
  • Typically more expensive than aftermarket parts
    

2. Aftermarket Parts

• Aftermarket parts are produced by third-party manufacturers but are designed to meet or exceed the specifications of OEM parts. These parts often come at a lower cost and may offer similar or even superior performance in some cases.
  
• Pros:
  • Lower cost
    
  • Availability of a wider range of products
    
  • Some aftermarket parts offer improved features (e.g., upgraded filters, stronger materials)
    
• Cons:
  • Quality may vary between manufacturers
    
  • Potentially no warranty support from the original machine manufacturer
    

3. Used or Reconditioned Parts
