Cummins QSB5.9-C180-34 Diesel Engine — 180HP | Tier 3 | DCEC Factory Supply

The Cummins QSB5.9-C180-34 is a 5.9-liter, inline 6-cylinder turbocharged electronic diesel engine manufactured by Dongfeng Cummins Engine Co. (DCEC), delivering 133 kW (180 HP) at 2200 RPM with a peak torque of 770 N.m at 1400 RPM. Built to Tier 3 / EU Stage IIIA emission standards and equipped with a BOSCH High-Pressure Common Rail fuel system, it is a primary OEM power source for mid-class excavators, wheel loaders, and heavy construction machinery across international markets. All units supplied through DCEC's certified supply chain with full serial number traceability.

Technical Specifications

QSB5.9 Series Comparison

The C180-34 sits in the mid-high power range of the QSB5.9 platform. Its defining characteristic versus adjacent variants is the low-RPM torque peak (770 N.m available from 1,400 RPM at a rated speed of 2,200 RPM) — making it the preferred configuration for hydraulic-heavy equipment where low-end pulling power determines cycle efficiency.

If you are not certain which variant matches your machine's OEM specification, provide your ESN or nameplate data and we will confirm the correct model before order placement.

Replacement Compatibility & Fitment Verification

The QSB5.9-C180-34 is a certified OEM power unit for mid-class construction machinery across major equipment manufacturers. Typical compatible platforms include 20–25 ton hydraulic excavators and 4–5 ton wheel loaders from brands including Sany, XCMG, Liugong, Lonking, and equivalent OEM configurations.

Fitment varies by production year and regional specification: Two machines of the same model may carry different engine variants depending on emission zone, market, and build date. Confirming fitment from the machine model name alone is unreliable.

ESN & Nameplate Verification Process:

· Step 1 — Locate your engine serial number (ESN) on the engine block or photograph the engine nameplate
· Step 2 — Submit ESN or nameplate image to our technical team via the inquiry form below
· Step 3 — We cross-reference against DCEC configuration records and confirm exact fitment
· Step 4 — A verified quotation is issued within 24 business hours — no commitment required at this stage

This process eliminates the single largest risk in engine procurement: ordering a unit that cannot be installed.

FAQ

Q1: How do I confirm the QSB5.9-C180-34 is the correct engine for my machine?

Submit your engine serial number (ESN) or a photo of the engine nameplate — our technical team will verify fitment against DCEC configuration records and confirm before any order is placed.

Q2: What is the difference between the QSB5.9-C180-34 and C180-31 or C180-33?

The C180-34 produces peak torque at 1,400 RPM with a rated speed of 2,200 RPM; the C180-31 operates at 2,400 RPM and the C180-33 at 2,000 RPM — each variant is tuned for a different equipment duty cycle and should not be substituted without OEM verification.

Q3: Are these genuine DCEC Cummins engines or remanufactured units?

All units are sourced directly through DCEC Cummins' certified supply chain; remanufactured units are available separately upon request — please specify at time of inquiry.

Q4: What is the actual delivery time for an in-stock unit?

In-stock units are dispatched from Shenzhen within 7-15 business days of order confirmation; sea freight transit time to destination port is additional and varies by route.

Q5: Can the electrical system be changed from 24V to 12V?

Yes — 12V / 500A starter motor configuration is available; specify your requirement at time of order and we will confirm the modification before shipment.

Q6: What payment methods and trade terms do you accept?

We accept T/T (bank transfer) and L/C (letter of credit); supported trade terms are FOB, CIF, and CNF — confirm your preference when submitting your inquiry.

Q7: Can QSB5.9 engine parts be sourced from you separately without purchasing a complete engine?

Yes — genuine DCEC Cummins parts for the QSB5.9 series are available individually; provide your ESN and the required part name or number for a parts quotation.
