Hitachi UHO 25 Engine type?

[skadill]

Hi,This 1984 to 1986 Hitachi UHO25 came with a Nissan or either an Isuzu engine.I'm not certain as to which one this is.There isn't a name on the valve cover ,and label is smeared off.
grateful for any info on it,Thank you

My memory of Hitachi's of that vintage was either Izuzu or Hino. Don't recall any Nissans.

Looks like Isuzu to me, but I wouldn't bet the ranch on it...
