[TowerTalk] Safely Unscrewing Cap Screws on the TX-472 Hub City Worm Gear Box

[Fred Hurd]

Please some good advise for safely unwinding (and rewinding/tightening) the cap screws on the TX-472 US Tower Hub City Gear Box in order to drain and refill the oil lubricant. The Cap Screws on my unit are heavy painted, so I will need a safe procedure for loosening the screw without causing damage. Advise from someone who has replaced the oil in their unit would be greatly appreciated.
