Product Overview
When a dozer's hydraulic gear pump fails, the machine stops working - the blade cannot lift, the ripper cannot engage, and the machine sits idle. The CAT 269-0004 is the OEM-specified hydraulic gear pump for Caterpillar D3K, D4K, and D5K series track-type tractors equipped with the C4.4 engine.
This external gear pump generates the hydraulic pressure and flow required to operate the blade lift, blade tilt, and steering circuits on these dozers. It mounts directly to the engine-driven accessory drive, requiring no adapter plates or modified plumbing in most applications.
Which dozer do you have? The 269-0004 is compatible with the following model variants:
| Dozer Series | Compatible Variants |
|---|---|
| D3K | D3K2LGP, D3KLGP, D3KXL, D3K2XL |
| D4K | D4KLGP, D4KXL, D4K2LGP, D4K2XL |
| D5K | D5KLGP, D5KXL, D5K2LGP, D5K2XL |
All variants are powered by the Caterpillar C4.4 engine. If your machine matches one of these configurations, the 269-0004 is the correct replacement.
Core Advantages
2.1 Direct OEM Replacement – No Modification Required
The 269-0004 is manufactured to Caterpillar OEM specifications for the D3K/D4K/D5K platform. It is a direct bolt-on replacement for the original pump: same mounting flange, same drive coupling, same port locations. Installation requires no modification to the engine accessory drive, hydraulic lines, or mounting brackets.
What this means for your repair: You order one part number, receive the correct pump, and install it. No adapter kits, no fabrication, no second attempt.
2.2 Full Model Coverage – One Part Number, Multiple Dozers
The 269-0004 serves the entire D3K/D4K/D5K range with the C4.4 engine. Whether you are maintaining a fleet of mixed dozer models or a single machine, stocking one pump part number covers multiple machines. This simplifies spare parts inventory for fleet operators and repair shops alike.
2.3 Built for the Dozer Duty Cycle
Dozer hydraulic systems operate under continuous high-load cycling - blade lift and tilt under heavy soil resistance, steering corrections under full load, ripper operation in hard ground. The 269-0004 is engineered for this duty cycle, with a robust cast housing and precision gear set designed to maintain flow and pressure under sustained operation.
2.4 Cross-Reference Verified
We verify compatibility against the CAT parts system and cross-reference databases before shipping. Each pump is checked against the following interchangeable part numbers:
269-0004 / 2690004 (CAT standard)
CA2690004 (CAT alternative format)
Important note on SGP2-48L194: This Shimadzu/KYB part number appears in some cross-reference listings for the 269-0004, but it is a different pump specification (48.0 mL/r displacement) and is not a direct interchange. Do not substitute SGP2-48L194 for 269-0004 without confirming your machine's actual requirements.
Q1: Which Caterpillar dozers does the 269-0004 fit?
The 269-0004 fits D3K, D4K, and D5K series track-type tractors equipped with the Caterpillar C4.4 engine. The full compatibility list includes:
D3K: D3K2LGP, D3KLGP, D3KXL, D3K2XL
D4K: D4KLGP, D4KXL, D4K2LGP, D4K2XL
D5K: D5KLGP, D5KXL, D5K2LGP, D5K2XL
Confirm your machine's model and serial number before ordering.
Q2: What is the displacement of the 269-0004 pump?
Published specifications vary across aftermarket sources - some list 20 cc/rev, others list 33.20 cc/rev. Because Caterpillar does not publish a single confirmed displacement for this part number in all channels, we recommend confirming against your machine's original pump data plate or consulting your CAT dealer with the machine serial number before ordering.
Q3: Is the 269-0004 the same as SGP2-48L194?
No. The SGP2-48L194 is a Shimadzu/KYB gear pump with a nominal displacement of 48.0 mL/r and a maximum pressure of 200 bar. The 269-0004 is a Caterpillar-specified pump for the D3K/D4K/D5K platform. While both appear in some cross-reference databases, they are different specifications. Do not assume direct interchange without verifying your machine's requirements.
Q4: What does CA2690004 mean?
CA2690004 is an alternative format of the same Caterpillar part number. The "CA" prefix is used in some CAT parts systems and aftermarket catalogs. It refers to the identical 269-0004 pump - no specification difference.
Q5: Is this a genuine Caterpillar pump or an aftermarket replacement?
We supply OEM-quality aftermarket replacements for the 269-0004. These are manufactured to Caterpillar specifications for fit and function, providing a cost-effective alternative to dealer pricing. If you require a genuine CAT-branded unit, please specify at the time of inquiry.
Q6: What warranty is provided?
Warranty terms vary by supplier. Typical coverage for the 269-0004 is 6 to 12 months from date of shipment. Confirm the specific warranty terms with your supplier before purchase.
Q7: How do I confirm the rotation direction of my pump?
The 269-0004 is configured for a specific rotation direction matching the C4.4 engine accessory drive. Before ordering, confirm the rotation direction of your existing pump by observing the input shaft rotation as viewed from the shaft end with the engine turning over (fuel disabled). Match the R or L designation accordingly.
Q8: What should I check before installing the new pump?
Three items before installation:
Suction line condition - a collapsing or restricted suction hose can cavitate the new pump within minutes
System relief valve setting - confirm it is set to the correct pressure for your dozer model
Case drain routing - ensure the drain line is unobstructed and returns to the reservoir below oil level
Q9: Do you provide test reports?
Yes. We can provide performance verification data for the pump before shipment, including flow and pressure test results. Test videos are available upon request.
