Valve Seat Inserts

Valve seat insert dimensions: OD, ID and height

Identify the seat insert and its position

Provide the complete engine version, OE reference or head marking, and identify intake or exhaust if known. Record outer diameter, inner diameter and height in millimetres. Add any steps or chamfers and the specified working angle where the drawing supplies it; do not infer these from a photograph.

Standard and repair sizes need separate confirmation

State whether the request concerns a standard part or a repair-size requirement. A worn sample measurement does not establish the nominal outside diameter, and a catalogue match does not set the head-pocket fit or machining method. Confirm the relevant drawing revision, material and inspection requirements with the supplier.

Prepare a valve guide or seat insert RFQ

List each reference, required quantity, complete engine model, intake or exhaust position, drawing revision, material and inspection requirements, packing and destination. Mark unknown fields for review. FarDrive coordinates authorized sales, specification questions, supplier quotations and technical or after-sales follow-up; availability and commercial terms are confirmed for the order.
