PROCUREMENT & TECHNICAL REVIEW
Specification & purchasing questions
What is the key specification of this version?
40.08 × 32.50 × 7.20 mm; 45° working face. The supplied exhaust specification has a 45-degree working face and 40.08 mm outer diameter. Check the paired intake seat and head version.
How should I distinguish another version with the same reference?

What information is needed for a quotation?
Send this FarDrive reference, quantity, engine details and destination. Specify material, finished or unfinished condition, inspection and delivery requirements. FarDrive coordinates sourcing, technical support and quotation terms for the enquiry.
What should I send when enquiring about FD-VS0307?
Identify FD-VS0307 and primary reference 3940153. The listed dimensions are 40.08 × 32.50 × 7.20 mm; use the specification notes above to distinguish nominal, measured and finished conditions. Send the complete engine version, position, drawing revision or labelled sample measurements, quantity, material and inspection requirements, packing and destination. Keep uncertain fields marked for review.
How can I confirm the photographed sample?
Ask for photographs tied to FD-VS0307, including the complete part, both ends or faces, markings and labelled measurement positions. A category sample photograph does not establish this reference, a precision dimension or the material grade. Agree the drawing and sample acceptance scope before a batch order.
How are samples, price and delivery agreed?
For valve guides and seat inserts, the first sample is free when you provide a drawing. Confirm the sample specification and quantity first; freight, tooling, development and other charges are agreed separately. Price, availability, lead time, inspection documents and delivery terms are confirmed in the written quotation for the enquiry.
