From the part number on the identification plate of the existing turbo — it captures the exact specification the engine was built with. If the plate is gone, the engine serial number and CPL or engine code identify the build. Send either via Ask Simon or WhatsApp and the unit can be confirmed before ordering.

Holset is Cummins' own turbocharger operation, so a large share of Cummins engines carry Holset-numbered units from the factory — HX-series references are common on the plates. Listings here carry the OE cross-references where they apply, so a Holset plate number routes to the correct replacement.

Most turbo deaths are secondary: oil starvation or contamination from a blocked feed line or overdue filters, crankcase breathing faults pushing oil through the seals, or boost-control and overspeed problems. Fix the cause first — replace oil feed lines, change oil and filters, check breathing and charge-air pipework — or the replacement inherits the same fate.

Units are genuine, supplied through official channels with the manufacturer's standard warranty — specification details sit on the Technical Specifications tab of each listing. Where a listing is sold on an exchange basis, the surcharge and old-unit return terms appear on the product page.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.

Cummins turbochargers cover the replacement units for the diesel engines that power a large share of the UK's trucks, plant, generators and agricultural machinery. PartsForMachines supplies genuine replacement turbos for Cummins engines, matched by turbocharger part number, with the OEM references and engine applications listed on each product page so a fitter can confirm the unit before it ships.

The part number on the identification plate of the existing turbo is the reliable route to the right replacement: it maps to the exact specification, compressor trim, turbine housing and actuator that the engine was built around. Where the plate is unreadable, the engine serial and CPL or engine code usually identify the unit, and Ask Simon on the product page handles exactly that kind of confirmation. Cummins engines across the B, C and L series and their successors have run turbochargers from the major OE manufacturers, including Holset, Cummins' own turbo arm, so cross-references between OE numbers and replacement references appear on the listings where they apply.

A turbo replacement only holds if the original failure cause is fixed: blocked or degraded oil feed, crankcase breathing faults and boost-control problems will take a new unit out as fast as the old one, so oil lines, filters and charge-air condition belong on the same job. Units listed here are genuine, supplied through official channels, with the manufacturer's standard warranty. For urgent fitment confirmation against an engine serial, or lead-time checks on a specific unit, contact the team via WhatsApp 07754288583.
