Product FAQ

Questions buyers ask about 188-8739

Is 188-8739 new, remanufactured or used?

188-8739 is supplied remanufactured: rebuilt with new wear parts and tested before dispatch, then photographed and packed. Core return and core deposit terms are confirmed on the quotation — ask before ordering if your programme requires core credit.

How do I confirm 188-8739 fits my engine?

Fitment is listed, not guaranteed. Listed applications: CAT C-9 (HEUI) — note: C-9 differs from C9 ACERT; confirm by old unit. 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.

What is the minimum order quantity for 188-8739?

The listed minimum order is 1 pc. Factory packing is 6 pc per box, 10.2 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.

Is 188-8739 an OEM Caterpillar part?

188-8739 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.

Can you check my old part number against 188-8739?

The main references we list for this part are 217-2570 / 235-2888 / 235-9649 / 236-0962 / 10R7224 / 172-5780. 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.

What warranty applies to 188-8739?

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.

Which fuel system does 188-8739 belong to?

Fuel system: HEUI hydraulic electronic unit injector. Injectors from a different fuel system do not interchange with 188-8739, 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.

Terms behind these answers: warranty & shipping · testing & packing. Fitment questions go to our technical team.
