Recently, a wa500-6 wheel loader came into our shop with a transmission filled with hydraulic oil and experiencing overheating issues. We are in search of a workshop manual for the wa500-6 model to help guide us in possibly needing to remove the cab to repair the hydraulic pump for a reseal. If anyone has any guidance or resources on this specific model, we would greatly appreciate it.
Before jumping into troubleshooting, there are several key questions to consider. 1. Did the issue suddenly arise, or has it been gradually worsening over time? 2. Have there been any changes in how the equipment is being used, such as a switch from loading trucks to feeding a crusher? 3. Is there a new operator who may not be operating the machinery correctly? 4. Is there any indication of a slipping clutch? 5. It is crucial to ensure the oil cooler is clean and check for any pressure drops, as this could indicate a blockage. Additionally, low pressure could suggest internal leakage within the system. 6. Have there been any changes in ambient temperature, and is the transmission oil suitable for these conditions? 7. Check the clutch pressure for any signs of bypassing or leaks. 8. Keep an eye out for foaming oil, which could be a result of issues with the suction hose to the charge pump. By addressing these questions and concerns, you can effectively troubleshoot and identify any potential issues with the machinery.
Komatsu loaders are becoming less common, making it difficult to provide information on the Dash 6 model. Older models of these machines typically had the hydraulic pump on one side and the transmission pump on the other, with a gear pump serving as a switch pump at the back. This pump prioritized steering, with the excess flow going to the main hydraulics. Issues like the one you're experiencing often arose around the 5,000-hour mark on older machines. Due to the aluminum bodies of the pumps, it was more practical to replace the hydraulic pumps rather than attempting to reseal them. Thankfully, on older models, the pumps could be accessed without having to remove the cab, although it was still a challenging task. It's been reported that newer machines now utilize piston pumps, but still feature the aluminum body gear-type switch pump piggybacked on the transmission pump. Keep us updated on your findings.
I appreciate the advice and would like to delve into a Komatsu manual to learn the procedure for removing the Hydraulic pump. After consulting with some Komatsu experts, it seems that removing the pump entails taking off the cab first. John C. mentioned that they don't encounter many Komatsu loaders nowadays, so his knowledge on the Dash 6 model is limited. Previous versions of these machines had the hydraulic pump on one side and the transmission pump on the other side, with a gear-type switch pump attached to the back. This switch pump prioritized steering and then directed excess flow to the main hydraulics. Issues like the one you mentioned were common around the 5,000-hour mark on older models. Due to the aluminum bodies of the pumps, it was often easier to replace them rather than attempt to seal them. Older models allowed for the pump removal without having to remove the cab, although it was still a challenging task. I've heard that newer models use piston pumps but still have the aluminum body gear-type switch pump connected to the transmission pump. Keep us updated on your progress.
Inquiring about the removal of the Hydraulic pump in a Komatsu machine? George Catman is seeking advice on the best approach, as he has been informed by Komatsu experts that it involves taking off the cab to get to the pump. If you're experiencing hydraulic issues with Volvos, keep in mind that they have a hydraulic hand brake on the transmission that might be a potential source of leaks. Unsure about the setup in Komatsus? Aiden has a manual for a wa500 and is willing to share it with you. Just drop him an email to receive a copy.
Hello Aiden, I'm unsure how to contact you via email directly, but I believe that having the workshop manual for the WA500-6 would be extremely beneficial. Thank you.
