A hydraulic-cylinder replacement is an interface-matching job. Measure the old cylinder and machine attachment points instead of searching by colour or a partially readable label.
Measure the Retracted Geometry
Record centre-to-centre or face-to-face mounting length with the cylinder fully retracted, then confirm stroke. If safe motion is not possible, measure the machine geometry and consult equipment documentation.
| Measurement | Why it matters |
|---|---|
| Retracted mounting length | Controls base machine geometry |
| Colpo | Sets total travel |
| Pin diameter + clevis/lug width | Defines mechanical fit and bearing area |
| Rod-end thread/eye | Defines moving connection |
| Port thread + orientation | Controls hose compatibility/clearance |
| Body clearance | Prevents interference through motion |
Photograph the Interfaces
Useful photos show both mounts, each port, the rod end, any valve block and the cylinder installed. A nameplate or part number supports identification but should not replace measurements.
Mark Fixed vs Flexible Interfaces
Some replacements must be drop-in; others can accept an adapter or changed port position. Mark each interface as fixed or flexible so alternatives can be evaluated without changing machine geometry.

Frequently Asked Questions
Can I match bore and stroke only?
No. Mounting length, ends, pins, ports, clearance and duty also matter.
Which length comes first?
Fully retracted mounting length because it controls the base geometry.
Are photos enough?
Photos help but critical dimensions are still required.
What if the part number is unreadable?
Measure interfaces and send photos plus machine model/function.
Should I reuse a bent mount?
Inspect and correct the linkage first; misalignment can damage the replacement.
