EQ Hydraulic Pump 3195KS Parts Diagram, Solenoids & Valve Guide

Identify the key service parts on EQ Systems 3195KS and selected other hydraulic leveling pumps using EQ's valve and contactor charts and photographs of corresponding replacement parts. This guide distinguishes complete assemblies, contactors, cartridge valves and special override kits rather than assuming they fit every pump.

Record the pump label first. Similar-looking hydraulic power units may have different reservoir capacities, manifolds, motors and electrical parts. The schematics below illustrate the general location and purpose of parts, not exact installation or hose routing.

Confirm which components are included. Equalizer identifies 3329K reservoir, 3330 fill cap, 3332 motor and 2994 contactor as 3195KS assembly components, while the 3195KS product description indicates the reservoir is excluded. Also, Equalizer identifies 7827 as the 3073 valve plus 3074 coil kit, while the product description does not clearly confirm whether the coil is included. Confirm the included parts before ordering.

Pump and service parts by number

Callout EQ number Component Selection requirement
A 3195KS Hydraulic pump assembly Manufacturer assembly identification differs from the store description regarding whether reservoir 3329K is supplied.
B 2994 Reversing motor contactor Manufacturer shows a direct replacement for the matching 2994 style; original terminals still need checking.
C 3073 Deltrol MTE cartridge valve Valve alone is not a complete 1745, 1716 or 1131 conversion; those require coil 3074 too.
D 7827 MTE valve-and-coil conversion kit number EQ calls 7827 the 3073-plus-3074 kit. Store wording does not clearly confirm coil included; check package.
E 1444 Starter solenoid (separate system) Not interchangeable with reversing contactor 2994. Older wired conversions can require special instructions.
F 2047K 1,200-psi pressure switch service part Check the original switch number and installed pump system; not universal across EQ models.
G 7493 BI-ROT DV-2 manual-override kit EQ instructions cover 2032, 2042, 2390 and a differently wired 3043 pump. Not a generic cartridge-valve replacement.

Why the valve and coil numbers matter

MTE pump valve replacement guide: old valve numbers versus 7827 kit Older 1745, 1716 and 1131 valves require the 7827 Deltrol valve-plus-coil conversion, while old 1717 DV1 uses direct 1717 valve plus 1746 coil. No interchange implied. Older MTE valves: 1745 / 1716 / 1131 7827 = 3073 valve + 3074 coil Manufacturer requires both for conversion. Confirm coil in store package before order. Different valve: original 1717 DV1 Direct 1717 valve + 1746 coil Do not substitute 7827 on appearance.
Original comparison redrawn from EQ's MTE valve and coil replacement chart. See the official PDF for photographs showing the red knob and hole-row variants.

EQ's MTE valve chart directs owners of older 1745 DV2, 1716 manual-override and 1131 non-manual-override valves to replace both components with 7827, consisting of Deltrol valve 3073 and coil 3074. The separate older 1717 DV1 arrangement instead uses direct replacement valve 1717 and coil 1746. A standalone 3073 valve cannot be assumed to complete the first three conversions.

3195KS reservoir and contactor references

EQ's 2023 reservoir chart maps the 3195KS pump to 3329K reservoir. Its manufacturer replacement-pump documentation also identifies 2994 contactor, 3330 fill cap and 3332 pump motor as assembly references. The exact manifold valve count varies with the vehicle equipment package, so the illustrated valve positions are not intended as an exploded parts count.

Solenoid and override differences

EQ Systems original 2994 contactor and 1444 solenoid visual replacement chart. EQ's manufacturer photographs show the valve, coil and contactor components. Open the full-size factory photograph chart if the document viewer does not load. This identification chart does not establish fitment for a different pump model.

2994 is a reversing contactor; 1444 is a different starter-solenoid part. EQ's replacement chart identifies some 1444 replacements as direct but shows older wired-solenoid conversions that require included wiring instructions. Do not substitute 1444 for 2994 without manufacturer approval.

2047K is cataloged as a 1,200-psi pressure switch. 7493 is a separate BI-ROT DV-2 manual-override conversion kit, for specific 2032, 2042 and 2390 pumps plus a differently wired 3043 installation. Neither item is a universal replacement for a manifold cartridge valve.

Safety: these documents are identification references. Hydraulic systems can move without warning. Do not disconnect pressurized lines, bypass protection or use the conceptual drawings as installation instructions. A qualified technician should follow the service instructions for the installed pump revision.
