7H1680 Grease Pump for CAT 955, 977A, 955C & more

The 7H1680 grease pump is a lubrication pump designed to deliver grease under pressure to critical points on Caterpillar heavy equipment. It helps ensure moving parts like bearings, joints, and pins stay properly lubricated to reduce wear and extend service life.

The 7H1680 pump plays a specific role in its assembly on Caterpillar equipment, contributing to safe, dependable performance.

Here’s a general guide for installation:

1. Park the machine on level ground and shut off the engine.
2. Relieve any pressure in the existing grease system before beginning work.
3. Locate and remove the old grease pump and disconnect hoses or fittings.
4. Clean the mounting surfaces, inspect hoses and fittings for wear, and install the new 7H1680 pump in place.
5. Connect all grease lines and ensure each connection is secure.
6. Prime the pump and test it to verify proper grease flow to all lubrication points.

To install the 7H1680 properly, prepare the area first and confirm the result afterward. Use these steps:

1. Shut the machine down and isolate power before working on the assembly
2. Clean the mating surfaces and inspect them for wear or damage
3. Remove the old part and check the area for debris
4. Fit the new 7H1680 in the correct orientation per your service manual
5. Reassemble to specification and confirm correct operation before returning to service

The 7H1680 grease pump is compatible with many Caterpillar machines that require pressurized lubrication systems. Typical models include track-type loaders and heavy earthmoving equipment such as CAT 955, 955C, 977A, and 977D, along with other machines where the 7H-1680 part number is specified.

Fitment for the 7H1680 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. Please reach out to Propel Parts for help verifying fitment.

Yes, the 7H1680 grease pump is manufactured to meet or exceed OEM specifications for durability and flow performance. It features a robust construction with a steel body and components designed to withstand heavy usage and consistent lubrication demands.

Yes. The 7H1680 is manufactured to meet OEM specifications for tolerance and material quality. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications for dependable, long-term performance.

Inspect the grease pump regularly as part of routine maintenance. Look for signs of reduced grease flow, leaks, unusual noises, or difficulty priming. If any of these signs are present, or if the pump fails to maintain adequate grease pressure, replacement is recommended to prevent premature wear of machine components.

Plan to replace the 7H1680 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit.

Typical indicators include:

1. Weak or no grease pressure at lubrication points
2. Leaks around the pump housing or fittings
3. Unusual noise during pump operation
4. Frequent air locks or inability to prime

A worn 7H1680 usually gives early warning through the assembly it supports. Watch for these signs:

• Visible wear, cracking, or corrosion on inspection
• Reduced performance or reliability in the assembly
• Unusual noise, movement, or leaks near the part
• Premature wear on the components around it

A quality grease pump like the 7H1680 ensures consistent, high-pressure delivery of grease to bearings, pins, and joints. Proper lubrication reduces friction and wear, improves component life, and enhances overall machine performance and reliability especially in demanding construction, mining, or industrial environments.

A sound 7H1680 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. Related hardware on our site includes 6F9163 Gasket and 5P3193 Seal Lip Type.
