235-5261 Diesel Fuel Injector — CAT C9 (HEUI)

235-5261 is supplied new, as an independent aftermarket reproduction built to the fitment and function of the part it replaces. It is not a used or reconditioned unit, and it is not an OEM part.

Fitment is listed, not guaranteed. Listed applications: CAT C9 (HEUI) — excavators, motor graders. 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.

The listed minimum order is 1 pc (factory pack: 6 pcs). Factory packing is 6 pc per box, 10.8 kg. If you need a different quantity for a trial or a mixed order, ask — what we can actually ship is confirmed in the quotation, not on this page.

235-5261 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.

The main references we list for this part are 267-3360 / 235-5518 / 20R1917 / 553-2592 / 10R1582. A shared number in a cross-reference list is identification, not a guarantee of interchange, so we check the number on your old unit against the catalog before quoting.

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.

Fuel system: HEUI hydraulic electronic unit injector. Injectors from a different fuel system do not interchange with 235-5261, even where the engine family name looks similar. The engine plate plus the number on your old injector is what tells us which system your engine actually runs.
