CM058BK-IOR0

CM058BK-IOR0 is catalogued as CUMMINS INJECTOR O-RING. In service this component meters and atomises fuel into the cylinder. Its condition determines combustion quality directly, which means a worn or mis-calibrated unit shows up as fuel consumption, smoke and uneven cylinder loading long before it shows up as a fault code. This number is not mapped to a single engine family in our catalogue, which usually means it spans several builds — send the engine serial and we will confirm fitment against your unit specifically.

We hold no alternate or superseded numbers against this part. That usually means it is current, but it is not proof: if the number stamped on the part you are removing differs from this one, send a photograph of the markings before ordering rather than assuming the two are equivalent.

Buyers usually reach this number for one of a small set of reasons: black or white smoke under load that does not clear; rough running or a misfire that follows a single cylinder; rising fuel consumption with no change in load pattern; fuel dilution in the oil, or oil level rising between services; hard starting when hot, or a knock that appears as the engine warms.

We quote genuine Cummins through authorised UAE distribution as the default on injection components. Where a credible remanufactured or branded aftermarket option exists — and on the mechanical PT families it often does — we price it on the same quotation with the manufacturer named, so the comparison is in front of you rather than hidden in a description. We do not supply unbranded injection parts at any price.

This line is light enough that air cargo through Dubai is often economic, which usually means days rather than weeks to Hargeisa or Berbera. Where the order includes heavier items we will quote the split — air for what grounds the set, sea for the rest — rather than delaying the whole shipment.

To quote this line accurately we need the engine serial number and the CPL, or the ECM calibration on an electronic engine. Injection part numbers follow calibration, not engine name. Orders are confirmed with a 50% deposit, balance on shipment.
