With all the fun recently overhauling my USD Aquarius and Scubapro regs I got enthused and thought I would overhaul my old Kawasaki J1 unbalanced piston first stage. The second stage is around somewhere...
I had learned to dive on this reg attached to a J valved 72 cu ft (just left school no funds for a SPG till much later!) but had long relegated this 1970's era reg to the garage, providing air for a parts cleaning gun... hadn't been serviced in over a decade at least.
Once pulled down I was surprised at how well designed it actually was... certainly no cut-price engineering by the Japanese back in the day, note the Teflon thrust washers on the piston head and stem!
All bores were in excellent condition under the accumulated goop, so after a quick ultrasonic clean, l lightly greased the o-rings (which were still pliable) reassembled it and put it back for another stint as my garage workhorse
These seem similar to an early USD Deepstar reg but with some 'enhancements'... does anyone have any more history?
