Troubleshooting Front and Rear Speed Issues on Cat CS433: Hydraulic Pump and Axle Linkage Concerns

Question:

I was informed that the hydraulic pump for the rear axle may be faulty. Upon inspection, I noticed that the roller for the reverse and drive axle was rotating in the wrong direction. After checking the linkage, I discovered that the axle pump linkage had become loose, causing the issue. Currently, the roller is operating faster than the rear axle. Should I adjust the linkage from the axle pump to the roller pump or should I make adjustments to the hydraulic pressures?

After diagnosing the issue as a problem with pressure and linkage, I identified that the neutral link needed adjustment. I made the necessary adjustments to both the link and the pressure. The front pump operates as a roller, while the second pump functions as an axle. Despite using pressure gauges, I didn't notice any changes in pressure while adjusting it. To achieve the desired outcome, I resorted to a creative solution by using two pieces of duct tape on the roller and tire to ensure they rotated at the same speed.

Great job on your thinking! Were you able to get it up and running successfully?
