What the thread found

• Using a substitute motor bearing oil instead of manufacturer-specified oil may affect gimbal performance after disassembly and reassembly.
• Loose screws on the yolk bearing assembly under the trunnion cap can cause tilting drift when the gimbal is tilted beyond approximately 45 degrees and then released.
• Trunnion end caps should not make contact with or rub against the screw heads of the bearing assembly.
• Tilt bearing screws should be tightened rather than left loose.

Depends on

• The user substituted Trinity Perpetual Motion Ultra Lightweight motor bearing oil for the manufacturer's recommended oil, which may have contributed to the problem.
• The exact specifications for proper tightness of bearing screws and acceptable play in the pan assembly were not definitively established in the thread.
• The user did not remove tilt bearings during cleaning, so the full extent of disassembly may not have been performed according to standard procedures.
• Final resolution was pending consultation with manufacturer support.
