OEM replacement two-piece pump cover kit for EQ Systems AJ and AM single leg trailer jack pump models. Includes front cover, back plate, and screws. Compatible with five S-series pump models.
The EQ Systems 7740 is the OEM replacement cover kit for AJ and AM single leg trailer jack hydraulic pump models. The pump cover protects the hydraulic pump assembly, wiring connections, and valve components from road debris, water intrusion, UV degradation, and physical damage during travel and use. A cracked, broken, or missing cover can lead to accelerated corrosion of pump internals, connector failures, and contamination of the hydraulic system.
Unlike the single-piece covers used on other EQ Systems pump models, the 7740 is a two-piece cover assembly consisting of a front cover and a back plate, along with the mounting screws. Both pieces are required for complete coverage of the pump assembly — confirm that both the front cover and back plate are present when inspecting a damaged cover before ordering.
The 7740 is a complete two-piece cover kit that includes the front cover, back plate, and all mounting screws required for installation. No additional hardware is needed. The two-piece design is specific to the AJ and AM single leg pump models listed — other EQ Systems pump covers use a different configuration. When replacing the cover, inspect screw holes on the pump body for damage or stripped threads before installation.
The 7740 is designed specifically for the AJ and AM single leg pump models listed below. EQ Systems replacement covers are not universal — different pump models use different cover designs. If your pump model is not listed, refer to the Replacement Cover Chart available through EQ Systems Parts Identification Documents to identify the correct cover for your system, or contact EQ Systems support directly. Your full pump model number is typically found on a label on the pump body.
