Quick answer: A JCB hydraulic cylinder seal kit is sized by bore, rod, and gland, plus the stamp on the ram. Marketplace listings that say “3DX kit” or “60×100 dipper kit” are not fitment for your serial. Measure, photograph, then RFQ.
Field symptoms
Leaks at the gland, boom or dipper drift, and foaming oil drive searches for a JCB hydraulic cylinder seal kit. Inspect tube scoring and fluid cleanliness, not only the seal. System-wide mapping: hydraulic system failure guide. One-symptom page: 3DX cylinder leaking.
How to match the kit (procurement)
- Name the ram: boom, dipper, bucket, loader lift, or stabiliser. They are not one kit.
- Measure: bore inside diameter and rod outside diameter. Note units (mm).
- Photograph: gland plate, any OEM or casting stamp, and the rod wear band.
- Serial: dataplate on the same RFQ. 3DX and 3CX arm lines can overlap and still differ.
We confirm interchange in writing. Visual similarity is not a match. If the stamp is gone, use identify from a photo.
