Clutch Spring for Dayun 150: Long Life Version
This clutch spring is built for the Dayun 150 and supplied to a written specification, so the part that comes off the line in the next order matches the one you approved. Fitment, base material and finish are fixed before sampling starts — that is what keeps the long life version programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: warranty claims traced back to a single lot, or reorders that did not match the approved sample. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

What decides whether it lasts
- Material — Powder Coated Steel is the base; treat any substitution as a new approval.
- Hardness and heat treatment — recorded per lot, not per batch of paperwork.
- Fitment tolerance — checked on the actual Dayun 150 mounting, not on a catalogue drawing.
- Finish — anodising holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.
Processes used on this line
- sintering
- laser cutting
- powder coating

Fitment notes
Check whether the mounting points on your market version match the catalogue drawing — regional variants are the usual cause of a wrong first order.

Ordering

- Book inspection before the balance payment, not after it.
Questions buyers ask
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.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the E-mark-compliant build instead of a fresh interpretation.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
