Hydraulic Engine Mount Specification Example for Delivery Vans: Reinforced Build
Hydraulic Engine Mount Specification Example for Delivery Vans: Reinforced Build
This is a worked specification for hydraulic engine mount in a reinforced build 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 reinforced build version exists because the duty cycle on delivery vans is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.
Example specification
| Item | Hydraulic Engine Mount |
|---|---|
| Application | Delivery Vans |
| Version | Reinforced Build |

| Compliance | SAE J431 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Forged Aluminium, 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
- precision stamping
- ultrasonic cleaning
- gravity casting
- rubber vulcanisation
- surface grinding
- sintering
Where this example applies
Programmes that run reinforced build most often specify this build for delivery vans. Related applications include aftermarket retail, emergency vehicles, racing teams, off-road bikes, delivery vans.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 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
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.
