Having issues with determining the correct orientation for installing the spools in the main control valve of my Cat 304CR (NAD00987). Some spools appear identical on both ends, while others clearly indicate a specific orientation. The presence of a groove/ring on one end of all spools is making me question if it determines the orientation. Despite consulting the service manual, there are conflicting instructions with the parts manual, leaving me confused. The hydraulic schematic provided doesn't offer clarity either. Is there a definitive way to determine the correct installation orientation for the spools based on the schematic provided?
When working on an MCV, it is important to use the Service Manual alongside the Parts Manual for more detailed information, such as sectional views. It is recommended to take photos during disassembly and focus on one section at a time. The Parts Manual provides detailed information on the various sections of the MCV. I hope this information meets your needs, and I apologize if it does not.
Nige suggested that when working on an MCV, it is important to refer to both the Service Manual and the Parts Manual for detailed information and sectional views. It is recommended to take photos during disassembly and only disassemble one section at a time for clarity. The Parts Manual provides detailed information on the MCV and its various sections. If unsure about the correct way to install a spool, refer to the diagrams in the Parts Manual for guidance. In some cases, the diagrams may differ from the photos in the Service Manual.
Matt Howey inquired about the correct orientation for installing the spool based on the diagrams in the parts manual. He suggested that paint-marking them during disassembly could help with reassembly.
When disassembling the valve, it's helpful to mark the parts with paint for easier reassembly. However, it's crucial to understand the correct installation of spools to ensure proper functioning. The lack of information in the service manual is frustrating, so reaching out to the dealer for guidance may be necessary. It's important to address any potential issues with the installation process to prevent future problems.
I understand your frustration. I recently had to tackle a valve stack project involving a 24M, and the previous worker's haphazard approach left me to untangle the mess on my own.
