Fiat-Hitachi hydraulic excavators EX165 to EX455 (1986–2002) – the crawler excavators of the Italian-Japanese joint venture from San Mauro Torinese: EX for Excavator, the number as weight class in hundreds of kilograms
Fiat-Hitachi was from 1986 to 2002 the joint venture in which Fiat's construction division Fiatallis and Hitachi Construction Machinery built their excavators for Europe – at the San Mauro Torinese plant near Turin, with Hitachi designs of the EX range and Fiat sales; in 2002, after the CNH merger, the company passed into Fiat-Kobelco and then into New Holland Construction. The type logic follows Hitachi: EX stands for Excavator, the number gives the weight class in hundreds of kilograms – EX165 about 16.5 t, EX355 about 35 t, EX455 about 45 t – LC the long undercarriage (Long Crawler) with better stability, H the heavy-duty version, EL and BEH further undercarriage and equipment variants by factory logic. The engines are Isuzu diesels: the four-cylinder 4BG1 of 4.3 litres in the EX165, the six-cylinders 6SD1 of 9.8 litres and 6RB1 of 13.7 litres in the big models, at 2,000 to 2,300 rpm.

The register lists 7 versions with 76.1 to 225.1 kW from four- and six-cylinders of 4,302 to 13,701 cm³ and operating weights from 16,200 to 46,500 kg.
In the 1990s Fiat-Hitachi excavators were among the best-selling crawler excavators in Italy, France, Spain and Germany; technically they are Hitachi EX, which secures parts supply through Hitachi to this day.
On used machines, operating hours, play in slew ring, boom and stick bearings, the condition of undercarriage (tracks, rollers, sprockets), hydraulic pumps and cylinders, engine and radiator count; parts run through Hitachi and Isuzu.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
