Specs and history on cat 920 loader?

Seeking the info

any body any body

Hi RD6 plower,
seems WE can not help you much without a Serial Number.
920's were first produced back in 1969 in the USA and thru until 1985.
They were also produced in Belgium and Japan during the same era.
Early USA ones, 62K1-4605 used the D330 engine and the later 62K 04606-up used the 3304, both rated at 80 HP.
Standard bucket was rated at 1.5 yards or 1.15 metres.
Hope this helps.
Cheers,
Eddie B.
