EQ Systems Replacement Hydraulic Pump 3200KS | TJ Bumper Pull Tongue Jack

Replace the pump in your TJ bumper-pull tongue jack with the EQ Systems Hydraulic Pump Assembly 3200KS — the dedicated single-function pump for TJ single leg systems. Available at The RV Surplus.

⭐ Read the Model Number Off Your Existing Pump BEFORE Ordering

The pump model number is on the sticker on the pump itself, and it is the same as the SKU here. That number is the only reliable way to order: the same-looking pump can carry a different reservoir, cover, motor and manifold depending on the system it was built for.

⭐ Application: TJ Single Leg (Bumper Pull)

The 3200KS is used on TJ single leg systems — the EQ Systems bumper-pull tongue jack.

⭐ Before You Replace a Pump — Check Power First

Most pump complaints turn out to be power, not pump. Depending on the pump and motor combination, up to 160 amperes at a minimum of 10.5 VDC can be required to run the motor, through minimum 4 gauge power and ground cables. Some lithium batteries cannot deliver that running amperage.

• Check the ground to the pump stud for tightness and corrosion
• Check the positive cable to the motor solenoid for tightness and corrosion
• If the motor runs but nothing moves, look at the fluid level and trapped air before condemning the pump

Setting Up a New Pump

Mount the pump where the fill and breather cap can be reached for filling. Fill with Dexron III ATF to about one inch below the top of the reservoir with the jack fully retracted (level rises as the jack retracts). Remove the flush shipping plug and fit the vented breather cap before running the system, or the jack will operate erratically.
