Genuine Delphi 7185-900T 12V Fuel Shutoff Solenoid – 7167-620D

Description

Genuine Delphi 7185-900T 12V Fuel Shutoff Solenoid

This is a genuine Delphi 12-volt fuel shutoff solenoid for many CAV, Lucas, and Delphi rotary diesel injection pumps. The current Delphi service part number is 7185-900T, replacing older numbers including 7167-620D, 7167-620C, and 76579D.

This solenoid is commonly used on DPA, DPS, and DP200 injection pumps installed on Perkins engines, Massey Ferguson tractors, JCB equipment, Caterpillar applications, Case and Case IH equipment, Landini tractors, and other agricultural or industrial diesel machinery.

This is the twin-terminal version. It has two flat blade or Lucar-style electrical terminals. One terminal receives switched 12-volt power and the other connects to ground through the machine wiring.

Do not confuse this solenoid with the single-terminal 7185-900W. The terminal and grounding arrangement must match the pump and equipment wiring.

What Does the Fuel Shutoff Solenoid Do?

The fuel shutoff solenoid opens and closes the internal fuel passage in the injection pump as the ignition switch is turned on or off.

This is an energized-to-run solenoid. With the ignition switched on, 12-volt power energizes the solenoid and retracts its internal plunger, allowing the injection pump to deliver fuel. When the ignition is switched off, power is removed and the plunger closes the fuel passage, stopping the engine.

If the solenoid fails to open, the engine may crank normally but receive no injection fuel. If the plunger sticks in the open position, the engine may continue running after the key is switched off.

Common Signs of a Bad Shutoff Solenoid

A failed solenoid or a fault in its electrical circuit may cause symptoms including:

• Engine cranks but will not start
• No fuel reaching the injector lines
• No movement or click when 12 volts is applied
• Engine starts intermittently
• Engine shuts down unexpectedly while operating
• Engine stalls after the ignition circuit loses power
• Engine continues running after the key is switched off
• Solenoid works cold but stops operating when hot
• Loose, damaged, or corroded spade terminals
• Fuel leakage around the solenoid sealing area

These symptoms do not automatically prove that the solenoid is defective. A blown fuse, failed ignition switch, broken wire, poor ground connection, weak terminal connection, low system voltage, or internal injection pump problem may produce similar symptoms.

Quick Checks Before Ordering

1. Confirm the equipment uses a 12-volt electrical system. Do not install this solenoid on a 24-volt system.
2. Check the terminal style. This version has two flat blade terminals, not one central stud.
3. Check for switched power. One terminal should receive battery voltage with the ignition in the run position.
4. Check the ground circuit. The second terminal must have a good ground connection. Do not depend on the injection pump body to ground this two-terminal version.
5. Listen or feel for movement. The internal plunger should move when the solenoid is energized.
6. Compare the part numbers. Look for 7185-900T, 7167-620D, 7167-620C, or a matching equipment cross-reference.
7. Verify the injection pump number. Similar-looking solenoids are available with different voltages, terminals, plungers, and operating configurations.

Cross-reference numbers are provided for identification purposes. Equipment manufacturers sometimes used more than one injection pump or shutoff solenoid depending on engine serial number, production date, market, or previous repairs.

Common Perkins Engine Applications

Perkins number 26420472 is commonly associated with engines and equipment using compatible CAV, Lucas, or Delphi injection pumps. Cataloged engine applications may include:

• Perkins 1004-4
• Perkins 1004-4T
• Perkins 1004-40
• Perkins 1004-40T
• Perkins 1004-42
• Perkins 1006-6
• Perkins 1006-6T
• Perkins 3.152 and 3.1524 applications
• Perkins 4.41 applications
• Select Perkins-powered generator and industrial equipment

Verify the complete engine build list and injection pump number. An engine family alone does not guarantee that the same solenoid was used on every build.

Common Massey Ferguson Applications

Massey Ferguson numbers such as 1896464M1, 28480008, and 28730179 are commonly cataloged for tractors using the matching injection pump and twin-terminal solenoid. Model references may include:

• Massey Ferguson 220 and 231S
• Massey Ferguson 241, 251XE, 253, and 263
• Massey Ferguson 271, 271X, 271XE, and 281
• Massey Ferguson 3075, 3095, and 3125
• Massey Ferguson 3655 and 3660
• Massey Ferguson 6140, 6150, 6170, and 6180
• Massey Ferguson 6265
• Massey Ferguson 8210 and 8220

Some of these tractor models were built with more than one fuel system. Confirm the injection pump and existing terminal arrangement before ordering.

Common JCB and Industrial Applications

This solenoid is also commonly cataloged for Perkins-powered JCB and industrial equipment, including select:

• JCB 3C and 3CX backhoe loaders
• JCB 4CX backhoe loaders
• JCB 416, 428, and 432 equipment
• Caterpillar equipment using reference number 7W6249
• Industrial engines using compatible Delphi DP200 pumps
• Generator sets using compatible Perkins fuel systems

Application listings are a starting point only. The complete injection pump number remains the most reliable way to identify the correct solenoid.

7185-900T Versus 7185-900W

The 7185-900T and 7185-900W are both 12-volt fuel shutoff solenoids, but they use different electrical terminal and grounding arrangements.

• 7185-900T: Two flat blade or Lucar terminals. One terminal receives switched power and the other connects to ground.
• 7185-900W: One central stud-and-nut terminal and a different grounding arrangement.

Do not choose between these solenoids based only on the equipment model or the general shape of the part. Match the pump number, original part number, terminal arrangement, voltage, thread, and plunger configuration.

Need the Single-Terminal 7185-900W Version?

If your original solenoid has one central stud-and-nut terminal rather than two flat blade terminals, see our genuine Delphi 7185-900W / 7167-620A fuel shutoff solenoid.

Important Fitment Information

Do not order this solenoid using the tractor or equipment model alone. The same machine may have been produced with different injection pumps, and a replacement pump may have been installed during its service life.

The best way to confirm compatibility is to compare:

• The complete injection pump model number
• The number stamped on the old solenoid
• The equipment system voltage
• The two-terminal electrical connection
• The M14 x 1.5 mounting thread
• The original plunger and spring arrangement

When contacting us for help, send the complete number from the metal identification tag attached to the injection pump. The engine series number, tractor model, or casting numbers from the pump housing may not identify the correct solenoid.

Installation Notes

• Disconnect battery power before removing the old solenoid.
• Clean dirt and loose debris from around the solenoid before opening the injection pump.
• Compare the new solenoid with the original before installation.
• Confirm the plunger, spring, sealing O-ring, thread, and terminals match.
• Start the mounting threads by hand to prevent cross-threading.
• Connect one terminal to switched 12-volt power and the other to the correct ground circuit.
• Do not bend or loosen the blade terminals during installation.
• Switch the ignition on and verify that the solenoid operates.
• After starting the engine, inspect the solenoid area for fuel leakage.
• Confirm that the engine stops normally when electrical power is removed.
