Role design and job descriptions for Hydraulic Component Makers: honer, seal fitter and bench operator duties
Hydraulic units lose units to scratched bores and cut seals because roles are vague. One-page role sheets say who checks what before a unit moves on.

In a hydraulic bay a cylinder passes through boring, honing, plating, clean assembly and the test bench. At each step the person may assume the next one will catch an error. The honer lets a faint scratch go, the fitter fits a seal that was slightly nicked, and the bench operator passes a unit that held pressure briefly. Then the customer's repair shop returns it with blame attached.
Good role design names the specific checks per role: the honer checks surface finish and bore size against the drawing, the seal fitter checks the seal and the groove before fitting, the bench operator checks pressure hold for the stated time. Each role also says what must be written down and who is told. With this, a return can be traced to the step, not argued about.
How to set it up
1. Follow one cylinder from barrel to bench
Walk the path and note each hand-off. At each point ask: what could be wrong here that the next person cannot see?
2. Write three to five checks per role
For honing: finish, size, taper. For seal fitting: seal condition, groove, lubricant. For bench: hold time, leak, stroke. Use the unit's own terms and tools.
3. Add what each role may stop and who to tell
A fitter who finds a scratched bore should be able to stop and name who to call. Write this right down, so stopping is not seen as a failing.
4. Read each sheet with the person who holds the role
The honer and the seal fitter will correct details you cannot know. Our role design and job descriptions work uses the same method.
5. Use sheets to set skill steps and training
Each sheet shows what a beginner and an expert do. Use this to plan training and to decide who is ready to handle custom orders or customer returns.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- How many returned units in the last quarter were traced to a specific step
- Whether each role has a written list of checks
- Who decides to stop when a scratched bore is found
- Which hand-offs rely only on memory

Questions owners ask
One page: the checks before fitting, the tools, what counts as damage, what to record and who to tell. Add pictures of good and bad seals if you can.
Not different, but add a short note on who reviews the drawing and who approves a change. Custom work disturbs standard runs, so the ownership of changes should be written.
Yes. When a unit comes back, the sheets show which step should have caught the fault. Use this to fix the process and not to blame; people are more honest when the aim is to learn.
