501-6702 Hydraulic Cylinder Seal Kit for CAT 420F 430F Backhoe Loaders & 323F L Excavator
Product Overview
The 501-6702 hydraulic seal kit is a factory-manufactured aftermarket replacement kit cross-referenced against the Caterpillar part number 501-6702 (also written 5016702). Independent Caterpillar seal-kit catalogs place this number on Caterpillar F-series loader backhoes and on the 323F L crawler excavator: the MinnPar Caterpillar Seal Kit catalog and the CATERPILLAR SEAL KITS catalog reprint list 501-6702 for the 420F / 420F IT and 430F / 430F IT loader backhoes (lift cylinder) and for the 323F L crawler excavator bucket cylinder, while marketplace listings title it as a lift-cylinder, tilt-cylinder or bucket-cylinder seal kit for CAT F-series backhoes (Alibaba, oilsealkits.com, hightechseals.com.br, excavatorbreakerparts.com).
No independent source ties the 501-6702 number to mining crushers or hydraulic hammers, so the current page’s crusher/hammer positioning is treated as unverified and is not repeated in this copy. DJF Seals manufactures and supplies the 501-6702 kit at factory-direct wholesale pricing for Caterpillar dealers, repair shops and fleet maintenance programs; because more than one cylinder position appears across the catalog rows, please send the machine model and the cylinder to be resealed so the correct kit is matched before shipment.
Verified Application
The following data is presented exactly as the independent sources describe it:
| Part Number | 501-6702 (also written 5016702) |
| Product Type | Hydraulic cylinder seal kit (aftermarket replacement) |
| Cylinder Position | Catalog rows place it on the loader backhoe lift cylinder (420F / 420F IT, 430F / 430F IT) and on the 323F L crawler excavator bucket cylinder; marketplace listings also show a tilt-cylinder application |
| Verified Fitments | Caterpillar 420F, 420F IT, 430F and 430F IT loader backhoes (lift cylinder) and 323F L crawler excavator (bucket cylinder) per the CAT seal-kit catalogs; marketplace listings add 428F, 416F, 422F and 430F2 backhoe variants |
| Rod / Bore | Not independently confirmed — no verified figure is asserted |
| Condition | New, aftermarket replacement |
Note: the current page positions 501-6702 for mining crushers and hydraulic hammers. No catalog or listing source in this package supports that application. Materials, pressure rating, temperature range, exact piece counts, certifications and service life are factory data and are not independently verified.
Replacement Scope
This kit covers the sealing elements required to reseal a Caterpillar cylinder on the verified machine set. The verified reference is 501-6702 cross-referenced to the loader-backhoe lift cylinder and the 323F L bucket cylinder rows; the exact kit contents and piece counts should be verified with the factory against your cylinder before shipment.
Fitment Verification
The part number and fitments were verified through multiple independent sources:
- MinnPar Caterpillar Seal Kit catalog and the CATERPILLAR SEAL KITS catalog reprint (dokument.pub): “LOADER BACKHOE … 501-6702 420F/420F IT and 430F/430F IT” with companion numbers 469-9342, 469-9353, 495-5999 and 510-7944 — placing the kit on the F-series loader backhoes.
- Same catalogs, crawler excavator section: “Bucket. 501-6702 323F L. 469-9342, 469-9353, 495-5999, 510-7944, 510-7945” — placing the same number on the 323F L bucket cylinder.
- oilsealkits.com: “501-6702 5016702 HNBR PU PTFE fabric composite cylinder seal kit for CAT F-Series backhoe loader bucket cylinder overhaul repair” — corroborating the CAT F-series backhoe loader application.
- Alibaba listings: “Lift Cylinder Seal Kit for Backhoe Loader Models 428F 416F 430F2 422F 432F 420F 430F 5016702 501-6702” and “501-6702 Hydraulic Tilt Cylinder Seal Kit … 428F” — corroborating the F-series backhoe family and adding lift/tilt positions and the 416F / 422F / 432F / 430F2 rows.
- hightechseals.com.br (“501-6702 KIT DE REPARO CATERPILLAR”) and excavatorbreakerparts.com (“501-6697 501-6702 501-6704 oil seal repair kit for Caterpillar”) — corroborating 501-6702 as a Caterpillar cylinder seal/repair kit.
- Conflict note: the current page positions 501-6702 for mining crushers and hydraulic hammers. No independent source in this package supports a crusher or hammer application; every catalog and listing source places the number on Caterpillar loader backhoes and the 323F L excavator. The crusher/hammer positioning is therefore flagged as unverified and not asserted.
- Conflict note: the cylinder position is not uniform across sources — the catalogs group it with the loader-backhoe lift cylinder and the 323F L bucket cylinder, while marketplace listings also show lift and tilt applications for the F-series backhoes. The positions are presented as they appear rather than reduced to one.
- Materials, pressure, temperature, exact piece counts, certifications and service life are not independently verified.
