Hydraulic Engine Mount Specification Example for Long-Haul Trucks: Touring Version
Hydraulic Engine Mount Specification Example for Long-Haul Trucks: Touring Version
This is a worked specification for hydraulic engine mount in a touring version 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 touring version version exists because the duty cycle on long-haul trucks is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually lead time that slipped twice before bulk started.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — EPDM Rubber, 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
- laser cutting
- cold forging
- powder coating
- gravity casting
- robot welding
- ultrasonic cleaning
Where this example applies
Programmes that run touring version most often specify this build for long-haul trucks. Related applications include dealership service, city buses, camper conversions, scooter fleets, courier fleets.
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
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.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 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 ISO/TS 16949-compliant build instead of a fresh interpretation.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
