The Ryan Martin Fireball Jack Pack: AM 2/24 Hydraulic Trailer Jacks with Manual Override by EQ Systems

Ryan Martin Jack Pack AM Hydraulic Trailer Jacks 2/24 with 2 Function Manual Selector

This square tube in tube dual leg trailer jack is designed to bolt to the front of a Gooseneck trailer. A single switch operates the jack legs in tandem.

The AM series is the 4" x 4" square tube in tube jack, and this system lifts 24,000 lbs across the two legs. Two rocker switches, one for each leg, replace cranking a manual jack and run the jacks together or one at a time, which on a loaded horse or motorsports trailer is the difference between a two-minute hook up and a fight.

Specifications

Manual override: screw drive

If the system loses power, the pump is driven with an electric drill through the override shaft on the end of the motor, under the plastic cap or foil seal. The drill has to reach at least 2000 rpm or the pump will not develop enough pressure to move the jacks. The hex size and drill direction depend on the pump fitted to your unit, a 7/16 inch hex driver on most pumps and a 1/4 inch (6mm) Allen hex key on others, and on this independent control system the two cartridge valves must be closed first and returned afterwards, so follow the manual override section of the AM Dual Leg manual below. Take care that the drill does not contact wires or hoses.

Standard and optional equipment

• Commercial dual function pump with manual override
• Pump cover
• One control box with dual switches to operate each jack independently, which also lets the trailer be leveled side to side
• Key switch standard, which also prevents unauthorized use of the system
• Universal mounting brackets included
• Mounting bolt kit 7227 for the universal brackets, sold separately: one kit for a single leg jack, two for a dual leg
• Wire harnesses have a PVC high temperature nylon braid to hold up in the toughest environments

Battery requirement

EQ Systems recommends load testing the battery: it should deliver a minimum of 150 amperes at a minimum of 10.5 VDC for at least 30 seconds. Keep the terminals tight and free of corrosion, and keep the battery charged and maintained to the battery manufacturer's requirements. If the trailer sits between trips, Stay Charge parts 8400 and 8427 charge the trailer battery from the tow vehicle, and solar kit 70486 keeps the jack battery topped up.

Fluid and maintenance

The unit ships without fluid or mounting bolts. If you are mounting the jack on the included universal brackets, order bolt kit 7227 with it: one kit for a single leg jack, two for a dual leg. An AM dual leg system runs on Dexron III ATF, filled to about one inch below the top of the reservoir with the jacks fully retracted. Remember the level rises as the jacks retract. The reservoir must run with its vented breather cap fitted, not the flush shipping plug, or the jack will operate erratically. EQ Systems recommends owners inspect the system every 12 months, checking that all connections are tight and free from corrosion, particularly the ground to the pump stud and the positive cable to the motor solenoid.

Service parts

The replacement hydraulic cylinder for this jack is part 1179EQ. Cylinders are identified by the jack outer tube size and length, not by the bracket. The switchgear for a dual system is 6704.
