514-1734 Hydraulic Cylinder Seal Kit for the CAT 426 Backhoe Loader
Product Overview
The 514-1734 hydraulic seal kit is a factory-manufactured aftermarket replacement kit cross-referenced against the Caterpillar part number 514-1734 (the current DJF page URL writes the number as 5141734). Evidence for this number splits into two clusters that are documented side by side rather than merged: independent aftermarket marketplaces (eBay US/CA, Amazon, Alibaba) market 514-1734 as a hydraulic cylinder seal kit for the CAT 426 backhoe loader, while genuine Caterpillar SIS data mirrored on avspare.com, 777parts.com and machineryline.com lists 514-1734 as a KIT-SEAL servicing accumulator group 149-0686, a stabilizer accumulator used on later CAT backhoe loaders such as the 420D, 430D, 432E and 446D. The two clusters describe different product types and different model sets, and no independent source states a rod or bore size for this number.
DJF Seals manufactures and supplies the 514-1734 kit at factory-direct wholesale pricing for Caterpillar backhoe loader dealers, repair shops and fleet maintenance programs. Because two product types share this number across the source set, please send the machine model and the cylinder or accumulator to be resealed so the correct kit is matched before shipment.
Verified Application
The following data is presented exactly as the two independent evidence clusters describe it (genuine Caterpillar SIS mirrors vs. aftermarket marketplaces):
| Part Number | 514-1734 (Caterpillar reference; the current page URL writes it as 5141734) |
| Product Type | Two documented clusters: aftermarket listings sell a hydraulic cylinder seal kit; genuine Cat SIS lists a KIT-SEAL for accumulator group 149-0686 |
| Cylinder Position | Not identified by any independent source — the aftermarket cluster titles the CAT 426 application without naming a cylinder, and the SIS cluster is a stabilizer accumulator seal |
| Verified Fitments | Aftermarket cluster: CAT 426 backhoe loader (current DJF page title). Genuine SIS cluster: later CAT backhoe loaders such as the 420D / 430D / 432E / 446D (stabilizer accumulator group 149-0686) |
| Rod x Bore | No dimension is stated by any independent source — none is asserted here |
| Condition | New, aftermarket replacement |
Materials, pressure rating, temperature range, exact piece counts, certifications and service life are factory data and are not independently verified for this part number.
Replacement Scope
Because the source set does not agree on a single product type for 514-1734, the kit contents cannot be described from independent evidence: the aftermarket cluster sells it as a cylinder seal kit for the CAT 426 backhoe loader, while the genuine-SIS cluster describes a KIT-SEAL used inside accumulator group 149-0686 on the later backhoe loaders. Verify which application your machine needs; the exact component set is then matched to your cylinder or accumulator before shipment.
Fitment Verification
The number was cross-checked across the two evidence clusters:
- Genuine Caterpillar SIS mirrors (avspare.com, 777parts.com, machineryline.com): 514-1734 is listed as a KIT-SEAL servicing accumulator group 149-0686, a stabilizer accumulator used on later CAT backhoe loaders such as the 420D / 430D / 432E / 446D.
- Aftermarket marketplaces (eBay US/CA, Amazon, Alibaba) and the current DJF page: the number is marketed as a hydraulic cylinder seal kit for the CAT 426 backhoe loader.
- Conflict note: the two clusters describe different product types (cylinder seal kit vs. accumulator KIT-SEAL) and different model sets (426 vs. 420D/430D/432E/446D). Both readings are presented as-is; the application is re-confirmed with the customer before shipment rather than one cluster being erased.
- Dimension note: no independent source states a rod or bore figure, so no dimension appears in the copy above.
- Page-only wording: the current page meta describes the kit as an “OEM-Compliant Replacement for Construction Equipment Cylinders”; that compliance claim is page wording and is not independently verified.
- Materials, pressure, temperature, exact piece counts, certifications and service life are not independently verified.

FAQ
Q: Which machines does the 514-1734 seal kit fit?
A: The evidence splits into two clusters: aftermarket listings title the number for the CAT 426 backhoe loader, while genuine Cat SIS data ties it to later CAT backhoe loaders such as the 420D / 430D / 432E / 446D (stabilizer accumulator group 149-0686). Tell us your machine model so we match the correct cluster before shipment.
Q: Which cylinder does this kit service?
A: No independent source identifies a cylinder position. The aftermarket cluster sells the number as a hydraulic cylinder seal kit for the CAT 426, while the genuine-SIS cluster describes a KIT-SEAL used in accumulator group 149-0686 (a stabilizer accumulator seal), not a cylinder kit.
Q: What are the cylinder dimensions for this kit?
A: No independent source states a rod or bore figure for 514-1734, so no dimension is asserted in this package. Send the cylinder or accumulator details from your machine for matching.
Q: Is 514-1734 the same as 5141734?
A: The current DJF page URL writes the number without the hyphen (5141734); the hyphenated 514-1734 is the Caterpillar-style number used across the independent sources. Both spellings refer to the same listing family in the source set.
Q: What is the minimum order quantity?
A: MOQ: 5 kits.
