Bulldog 25,000 lbs Square Trailer Jack Drop Leg Sidewind 26" Lift w/ Spring Return Drop Leg

TWIN CAM DROP LEG JACK The Industry’s Strongest Drop Leg Jack. The BULLDOG® Twin Cam™ features a convenient, enclosed pin mechanism with “twin cam” action that will quickly make this heavy duty, drop leg jack the industry standard.

• The BULLDOG® Twin Cam Drop Leg mechanism allows an increase in the vertical static capacity by using two ¾” pins to transfer forces between the drop leg and inner tube of the jack.

• The unique Twin Cam drop leg mechanism actuates the drop leg pins in both directions, giving the operator full control over engagement and disengagement of the drop leg pins. The design does not rely on spring pressure alone to keep the pins in the locked position. Patent pending.

• The enclosed Twin Cam drop leg mechanism keeps dirt and debris from interfering with the engagement of the drop leg pins.

• The Twin Cam drop leg mechanism maintains tighter alignment between the drop leg tube and inner tube by having engagement on both sides of the drop leg tube.

Features:

• Easy access grease fittings allow for lubrication of internal jack gears and jack screw/nut.

• Patented screw stop prevents screw and/or nut damage when the jack is fully extended, keeping the screw in good condition for maximum screw/nut cycle life.

Install Instructions:

1. Remove the jack cross shaft. If your jack has non-welded hex bushings, refer to Service Bulletin F3310 (included). If you are installing the powered drive on a planetary two speed jack, refer to Service Bulletin F3376 (included). Refer to steps #1 through #5 for instructions on removing the cross shaft. Warning: Failure to follow these warnings and instructions may result in property damage, serious bodily injury, and/or death. ®
2. Replace the jack cross shaft temporarily with the powered drive/shaft. Install the shaft such that the powered drive is on the non-geared side of the jack with the motor down and within the profile of the jack (see Fig. 1).
3. With the powered drive/shaft temporarily installed, use it to locate the torque stop tube on the jack outer tube wall (see Fig. 1).
4. Place the torque stop tube on the rubber bumper (with the powered drive/shaft installed into the jack) and mark the location of the torque stop tube on the outer tube of the jack. Remove the powered drive/shaft and weld the torque stop tube on to the jack outer tube at your marked location (see Fig. 1).
5. Replace the powered drive/shaft. Make sure to place the energy-absorbing rubber bumper into the torque stop tube when assembling. This prevents the motor from rotating. Follow instructions of the appropriate Service Bulletin (see above) in reverse order to reassemble the jack. Use the standard hole for normal installation (see Fig. 2; do not use hole #2).
6. Attach the powered drive cover using the ¼” x 1” bolts and ¼” rubber bonded washers (included). Sandwich the cover between two rubber bonded washers on each bolt with the rubber side against the cover. Then, screw the bolts into the mounting flange holes. Torque the bolts to 6 ft. lbs. Your option is to apply a thread lock or retaining compound (not included) to the bolts. Place Bulldog decal (included) on outside of cover.

Wiring Instructions:

1. To avoid accidental shock and/or damage to the electrical system, disconnect the battery ground cable.
2. Attach the terminal box to the trailer at a location that will allow for connection of the powered drive leads to the terminal box studs. See wiring diagram (Figure 5).
3. Attach the powered drive leads and the wiring harness leads to the terminal box studs. To protect the leads, enclose them in a section of non-split tubing or loom (included). 
4. Locate and attach the switch box of the wiring harness at a desired location on the trailer (mounting hardware not included).
5. Attach the battery leads to the terminal box studs. Attach the terminal box cover.
6. Reconnect the battery ground and test the op
