Ask the Experts about this Bulldog Accessories and Parts

  • Will Replacement Planetary Gearbox Kit Work On Single-Speed Bulldog Landing Gear
    I called my contact at Bulldog about the Replacement Planetary Gearbox Kit, part # BD500330. They told me you can install this on your single-speed Bulldog jack. They said you would remove the old gearbox and replace it with the # BD500330, and may have to drill 4 holes to mate the gearbox up with your mounting plate but it will work find and actually turn your single-speed into a two-speed landing gear.

  • Gear Ratio of Bulldog 2-Speed Jack Planetary Gearbox
    The Replacement Planetary Gearbox Kit for Bulldog Jacks # BD500330 is a replacement for Bulldog jacks with a 10,000 lb lift capacity and 12,000 lb static capacity such as the Bulldog 2-Speed Jack # BD183416. This jack has two speeds of cranking: 1 inch every 27 turns in low gear and 1 inch every 9 turns in high gear. That said, since the Replacement Planetary Gearbox Kit # BD500330 is only designed for Bulldog jacks like the one I mentioned I would be unable to guarantee either that...
