Rebuilding the drive motor in a Bobcat 763 typically involves disassembling, inspecting, and replacing damaged parts. However, the primary problem faced by the user was that the motor wouldn't operate properly after reassembly. According to the forum discussion, several factors could contribute to this issue:
- Improper Reassembly: During the rebuild, some small parts might not have been installed correctly, preventing the motor from functioning as intended. It’s important to double-check the placement and sequence of parts, particularly smaller components like gears and seals.
- Hydraulic System Problems: The drive motor in the Bobcat 763 is often connected to the hydraulic system. If there are leaks, air bubbles, or issues with hydraulic pressure, it can affect the motor’s ability to start or run properly.
- Electrical Connection Issues: Electrical connections to the drive motor can also be problematic. Loose wires or poor connections can prevent the motor from starting. It’s crucial to inspect power lines, grounding, and control system wiring to ensure proper electrical contact.
- Quality of Parts: Using inferior or incompatible parts during the rebuild is another common issue. Ensuring that all replacement components meet the manufacturer's specifications is vital for a successful rebuild.
To address these issues, users can take the following steps:
- Double-Check the Reassembly Process: First, ensure that all parts have been assembled in the correct order and manner. Referring to the equipment manual or rebuilding guide can help verify that each component is installed properly.
- Inspect the Hydraulic System: Check the hydraulic fluid levels and make sure there is no air in the system. If necessary, perform a hydraulic bleed to ensure smooth fluid flow and proper pressure.
- Examine the Electrical System: Inspect all electrical connections, ensuring cables are tightly connected and free from corrosion. Also, check the battery charge and electrical system health to ensure the motor receives adequate power.
- Use OEM Parts: Always use high-quality, OEM-certified parts for the rebuild. Avoid using substandard or incorrect parts, as they could negatively affect the motor’s performance.
