The purchasing decision
Compare mounting holes, plate thickness and motor interface against the actual frame. Request a sample when the identity is uncertain. Record the approved replacement so the next order does not repeat the same identification work.
Keep these records
- Frame and arm revision.
- Critical dimensions.
- Sample fit approval.
Give each record an owner and a revision or date. If a supplier proposes a different part or test condition, record it as an exception for review before treating the quotation as equivalent.
Turn the review into a sourcing request
Start with the linked component checklist, add the actual platform and part identity, and state quantity, destination and timing. List unresolved requirements explicitly so the first discussion can focus on those gaps.
