C7 / C9 Injector Major Overhaul Kit

The C7/C9 major kit is supplied new. Kit contents are matched to the revision of the injector or pump it serves, so the exact contents list is confirmed against your old part number before quotation — ask for the list and we send it in writing.

Fitment is listed, not guaranteed. Listed applications: CAT C7 / C9 (HEUI) injectors — kit contents confirmed per order. Send the number stamped on your old unit, the engine model and serial, and — where the stamping is worn — a photo of the old part. We check it against the catalog manually and confirm in the quotation. The machine or engine model alone does not select the part.

MOQ for this part is quoted per order. Send the quantity you need and the destination, and the quantity we can actually ship goes into the quotation.

The C7/C9 major kit is an independent aftermarket replacement part, manufactured for BOSTEN and sold under our own brand. It is not a Caterpillar OEM part, and BOSTEN is not an authorized Caterpillar distributor or dealer. Caterpillar names and part numbers appear on this page for identification and cross-reference only.

This listing does not publish a cross-reference list for the part. Send the number on your old unit and we check it against the catalog manually — that check is done by our team, not by a lookup box on this page.

Warranty terms are confirmed per order and written on the quotation before payment. Different product lines and conditions carry different periods, so the terms for this part are not printed here as a generic number. Damage from contaminated oil or fuel and incorrect installation are excluded under the terms confirmed for your order.

Contents are matched to the injector or pump revision the kit serves, and the parts list is sent in writing before you order. The photograph on this page shows the kit type, not the individual contents — request the list for your revision and we confirm it against your old part number.
