Komatsu 6746113100, written 6746-11-3100 in Komatsu documentation, is the Komatsu part number for this Bosch injector. Cummins lists the same unit as 5268436, and Komatsu also references 5268436 because the engine is a Cummins-derived SAA6D114.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this injector need an IMA or IQA code written to the ECU?\u003c\/strong\u003e No. This CRIN3-18 injector is supplied without an individual injector accuracy code, so there is no calibration value to enter with a diagnostic tool after installation. Fitting is mechanical and electrical only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace all six injectors at the same time?\u003c\/strong\u003e We recommend testing and replacing the complete set. The six injectors have run the same hours and are worn to a similar degree, so fitting one new injector next to five worn ones leaves the cylinders working unevenly. The new injector then runs under a different load than the rest and wears faster, which is why a partial replacement often ends in a second repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is in the box?\u003c\/strong\u003e One injector, one injector body O-ring and one nozzle sealing washer, in the original Bosch packaging. Fitting the supplied new sealing washer is required, because the used washer is deformed by the clamping load and will not seal the combustion chamber again.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I also need a new connector tube?\u003c\/strong\u003e The injector connector tube F00RC00647 is the high-pressure link between the rail line and the injector, and its sealing cone is the part that suffers when an injector is removed after long service. Inspect it whenever the injector comes out; a scored or eroded cone is replaced, not lapped.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this injector work on a Cummins QSL9 engine outside a Komatsu machine?\u003c\/strong\u003e The injector is defined by the engine, not by the machine it sits in. Cummins QSL9 engines of 8.9 L built from 09\/2010 in the 169-280 kW range use this unit, whether the engine is installed in an excavator, a generator set or a truck. Confirm with the Cummins engine serial number and the number on the fitted injector.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo you ship worldwide?\u003c\/strong\u003e Yes, we ship worldwide.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I buy six pieces for a complete engine?\u003c\/strong\u003e Yes. Stock is held for this part number and six pieces can be ordered from this page; contact us before ordering if you need more than the quantity shown in stock.\u003c\/p\u003e\n\n\u003ch2\u003eCommon symptoms of a failing common rail injector\u003c\/h2\u003e\n\u003cp\u003eOn a Komatsu PC350, PC360 or PC390, a failing injector usually shows first as a rough, uneven idle with an audible knock from one cylinder, black or grey smoke under load, and a machine that no longer holds hydraulic performance when the engine is asked for full power. Excessive internal leakage raises the return flow, so the engine cranks longer before starting and may stall shortly afterwards, and the controller stores rail-pressure and cylinder-balance diagnostic trouble codes. A professional fuel-system test must be carried out before replacing any parts, to confirm the injector is the actual cause of the fault.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and system check\u003c\/h3\u003e\n\u003cp\u003eBefore any injector is fitted, the fuel system on the machine must be checked for contamination, whatever caused the original fault. On this engine the place to look is the fuel filter and its housing: debris, water and sticky varnish-like deposits collect there first and are the clearest evidence of the state of the rest of the circuit.\u003c\/p\u003e\n\u003cp\u003eComponents found to be contaminated are cleaned or replaced. The tank, the supply and return lines, the filter housing and filters, the rail and the high-pressure pump all fall inside the circuit that has to be dealt with. High-pressure lines and injector connector tubes are replaced, not cleaned, because their internal bore and sealing cone cannot be verified after cleaning. Flush the system, fit new filters and bleed the system according to the manufacturer's procedure.\u003c\/p\u003e\n\u003cp\u003eThe usual cause on machines working away from a workshop is poor or contaminated diesel: fuel stored badly on site, tanks that are not cleaned periodically, and contaminated containers or bowsers used for refuelling. Carry out all testing required to establish that the injectors are the actual cause of the fault before replacing any part.\u003c\/p\u003e\n\u003cp\u003eWhen fitting, use the new sealing washer supplied with the injector, seat the injector squarely in the cylinder head bore and tighten the clamp and the high-pressure line to the torque figures in the Komatsu or Cummins service documentation. No calibration code has to be written to the ECU for this injector. An injector fitted into a system that has not been decontaminated fails again within a short service period, and that failure is not covered by the warranty.\u003c\/p\u003e\n\u003cp\u003eBefore the new injector is fitted, the fuel supply system must be checked for contamination. Rust, water, sludge or varnish-like deposits, metallic debris or any other contaminant left in the tank, supply and return lines, filter housing or rail will damage the new injector within a short service period, and that damage is not covered by the warranty. Inspect and decontaminate the system, renew the filters and confirm that the fuel is clean before installation.\u003c\/p\u003e","brand":"Bosch","offers":[{"title":"Default Title","offer_id":54727812251981,"sku":"0445120305","price":478.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/3896\/3277\/files\/0445120305-bosch-crin3-injector-komatsu-cummins-main.jpg?v=1789394993","url":"https:\/\/expressdiesel.eu\/products\/0445120305-bosch-crin3-injector-komatsu-pc350-pc360-pc390-cummins-qsl9","provider":"Express Diesel","version":"1.0","type":"link"}
