i've been looking for a 4 pole gen head as well, hoping for one US made - agree with the comments about the chinese gen head bearings and windings
did find these italian made generator heads (Mecc Alte) and went to their web - they do have 4 pole gen heads, and there's a seller on ebay offering a lot of their 2 pole generator heads)
they've got a US distributor in IL, but no website - just phone contact - only website is the factory's italian web
one tip on northern hydraulic gen heads - it's crazy but their gen heads are cheaper when bought ordering them as a replacement part for one of their generators - i've got a 13Kw trifuel gen - and had a generator interlock kit on the panel box (keeps the generator breaker from being turned on unless the main breaker is turned off first) - anyway, had an electrician do some work on the panel box, adding a couple circuits, and the idiot moved the gen breaker to a new position - had a power outage, ran the generator (i had turned off main bkr) and when power came back on the generator started stumbling and running like it was either dragging a helluva load or fire at the plug was strangely intermittent - finally discovered it was being backfed from the panel box while it was trying to send current to the panel. Turned out, after full testing, my gen head is fine - i've got over 577 hours on that generator, between outages and monthly maintenance running.
when i called northern tech assist, was surprised the entire gen head was $599
you can actually build the gen i have, with all items supplied by northern for just over $2k not counting the tube frame. That includes the 10 gal tank with fuel guage & shut off. They retail it at $2900 last time i looked, $3400 for trifuel version
back to point - i'd love to see a quality 5-6K 4 pole gen, either US or Japanese mfgr'd, especially one there are good reports of durability, not just reports that they look good
