Hydraulic Engine Mount Specification Example for Workshop Replacements: Heavy Duty
Hydraulic Engine Mount Specification Example for Workshop Replacements: Heavy Duty
This is a worked specification for hydraulic engine mount in a heavy duty programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The heavy duty version exists because the duty cycle on workshop replacements is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.
Example specification
| Item | Hydraulic Engine Mount |
|---|---|
| Application | Workshop Replacements |
| Version | Heavy Duty |
| Base material | Semi-Metallic Compound |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | zinc plated |
| MOQ | 3,000 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | RoHS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Semi-Metallic Compound, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.
Processes involved
- ultrasonic cleaning
- heat treatment
- surface grinding
- die casting
- cold forging
- electroplating
Where this example applies
Programmes that run heavy duty most often specify this build for workshop replacements. Related applications include workshop replacements, long-haul trucks, fleet maintenance, off-road bikes, boat trailers.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.
What is the minimum order quantity?
The standard MOQ is 3000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
