The A-Drive 40:75 Drive Shaft Kit is designed to mount into the drive pipe section of the 40:90 double worm reducer gearbox. The driveshaft end with the input tab slides into the double worm reducer gearbox. Using the mounting holes on the opposite side of the drive shaft, attach the drive pipe with the bolt and nut provided. Made from hardened steel then zinc-plated for protection against marine conditions. The 40:75 double worm reducer gearbox is used in the BH-USA 3K (3,000 lb.) or 4K (4,000 lb.) A-Drive direct-drive boat lift hoist. The driveshaft will accept a KALS BH-USA A-Drive Limit Switch.
Please note that BH-USA supplies with all A-Drive drive shafts a GR5 hardened bolt to attach the drive pipe to the shaft. Only use the bolt provided by BH-USA, if you lose this bolt you must order another one from BH-USA Item 82011FA. Do not use any other bolt, by doing so the bolt may shear dropping your boat.
