first big machine i drove was a 814 super gave me the bug and havent been able to shift it since,i get the week tracking got it stuck on wetish stock piles quite a few times once muck got up under it not enough power to get it self out.the slide was a god send on housing sites for tight work areas

TBH I cant remember I think it was an early one so probably not a super and from what is said above re hyd flow again it would point to being non super , it had been painted in the contractors colours so didn't even have 814 decals on it never mind super if it was one
But yes compared to the isuzu motor the perkins much more thirsty , filling out of a drum back then so hard to be accurate but maybe as much as a 1/4 to 1/3 more fuel per day as I recall enough to stick in my mind and it was good few years ago.
The Isuzus where thought to be good on fuel back in the day plus probably a better (JAP) hyd pump so the engine just probably not revving as hard , the JCB by comparison was I would say running higher revs to do the same work.

Was there a significant difference between the white earlier and later and silver cab models ?

Got to agree with you on your fuel consumption comments. We had an 814 super slide that used to have a drink problem compared to any of the other machines around at the time. We ended up buying one of the first Daewoo machines that came other that I seem to think ran a lot of the old UH063 gear and it was a great machine. Later on I started running the Hitachi Ex range that still have a soft spot for me !

I will argue against the fuel thing, our 820 Super is far more fugal on diesel than our Isuzu powered JS220

I suppose we all have our own, and very different, experiences.....

The most fuel efficient engines ever used here have been the Perkins 6cyls,all the 6.354s ive had have been great on fuel,in my book one of the best engines ever made.

Does anyone remember or here of a prototype 6-8 ton JCB from the 70/80s? I remember seeing pictures of one but can’t find them now, think it was the 803 or 802 it was called?

A chap I know got 487k miles out of his before some twat stole it,only thing on engine replaced was the starter,he put its longevity down it never getting cold,he left it running most of the day.

All my 300s were good engines, I've had 7 in total 👍

i thought i would dig out a few photos of various 800 seriec machines including the later super version, Some are 812, 814, one is a super with river cleaning additional dipper arm on it and an 818 mono boom and 820 including one with a short dipper.

On the 6.354 debate ... great engines(y) but damned thirsty in cranes - on the road, at least:rolleyes: - great on site though :giggle::cool:
