Great customer service answered email question quickly.
My part was damaged in shipping and everyone was very helpful on get it resolved and sent me another free of charge.
A Delay Handled the Right Way
Honestly, if I were in Miami like my shipment was, I wouldn?t have been in a hurry to ship out either. I was frustrated at first ? delays cost me time on the job ? but Propel Parts stepped up.
Deb, Daniel and the team owned the mistake, kept the communication clear, and graciously refunded my shipping costs without making it a hassle. That kind of accountability is rare these days, and I genuinely appreciated how they handled it.
Things don?t always go perfectly, but these folks proved they?re more interested in doing right by their customers than just pushing parts out the door. Solid company, solid people.

Product Questions
Frequently Asked Questions
What is the function of the 6E3136 Pump G?
The 6E3136 Pump G is a hydraulic pump assembly that pressurizes and circulates hydraulic fluid in heavy equipment hydraulic systems. It converts mechanical power from the engine into hydraulic energy that powers steering, lift, blade control, and other functions. This type of pump is often a piston‑type main or steering pump in motor graders and similar machines.
How do I install the 6E3136 Pump G?
Here’s a general guide for proper installation:
- Turn off the engine and safely relieve all hydraulic system pressure before beginning.
- Locate the old pump and disconnect hydraulic lines, mounting bolts, and any electrical connections.
- Carefully remove the old pump assembly.
- Clean the mounting surface and inspect ports and fittings.
- Install the new 6E3136 Pump G, align it with mounting holes, and tighten bolts to the torque specified in your service manual.
- Reconnect hydraulic lines, refill the hydraulic reservoir with manufacturer‑specified fluid, and bleed the system as required.
- Start the machine and check for leaks and proper hydraulic pressure.
Which machines or systems use the 6E3136 Pump G?
The 6E3136 Pump G is compatible with a variety of Caterpillar equipment, especially motor graders and machines that require this specific pump part. These include CAT 120H, 120H ES, 120H NA, 120K, 12H, 12K, as well as some engine models like 3116, 3126, 3306, and C7 in applicable applications. Please reach out to Propel Parts for help verifying fitment.
Does the 6E3136 Pump G meet performance expectations?
Yes, the 6E3136 Pump G is manufactured to meet or exceed OEM specifications for performance and durability. Aftermarket versions like this are quality‑checked to ensure they fit and function similarly to the original Caterpillar pump, delivering reliable hydraulic flow and pressure under typical operating conditions.
How often should a pump like the 6E3136 be inspected or replaced?
Hydraulic pumps should be inspected during routine maintenance or at the first sign of declining performance. Regular checks include looking for fluid leaks, unusual noise from the pump area, reduced system responsiveness, or overheating. Replace the pump if it shows wear or failure to maintain required pressure.
What are common signs that the 6E3136 Pump G needs replacement?
Typical indicators include:
- Reduced hydraulic performance (slow or weak actuator movement)
- Unusual whining, knocking, or grinding noise from the pump area
- Visible hydraulic fluid leaks around the pump or fittings
- Overheating of the hydraulic system
Why is using a quality hydraulic pump important for equipment performance?
A quality hydraulic pump like the 6E3136 ensures consistent fluid flow and pressure to critical systems—such as steering, blade control, and lift functions. Using parts that meet or exceed OEM standards improves reliability, reduces downtime due to failures, and contributes to long‑term equipment durability and performance.
