Hi guys,
Last week I discovered very strange issue with my recently purchased second hand Scubapro S600 Classic.
When I press the demand lever fully down (purged) the top of the demand lever effort arm catches the guide sleeve of cracking effort adjustment knob.
This is a serious issue, because there is a risk of lever blockage in fully down position, which will result in free flow and huge gas loss and needs to be rectified before next dive.
It took me quite a while to figure out where the root of this issue is. Initially I thought that wrong guide sleeve could have been installed, but fortunately I had a fully working S600 and I managed to compare both regulators. It is the correct guide sleeve. No issue there.
Another possible problematic area could be the lever tabs (the lever load arm) blocking or interfering in the air barrel broached holes. I disassembled the S600 Classic and inspected thoroughly the broached holes, but I couldn't locate any issue there.
Next thing I did was to remove the lever suspecting bended or deformed demand lever but as you can see below the lever is in perfect shape.
I started comparing my defective S600 Classic with my functional S600 side by side and there is a visible demand lever length difference between the two regulators with the defective S600 Classic having longer demand lever.
I compared the dimensions of the defective lever with perfectly working S600 lever and I found the source of the problem: the defective lever has 14 mm feet length, but the working lever of my other S600 has 13 mm feet length.
I will order a new demand lever according to the S600 Classic diagram, but in the meantime I’m wondering how this happened?
Are you aware of different demand lever lengths despite their identical look?
Also do you know if the metal barrel upgrade kit of Scubapro comes with lever or just the barrel?
I hope this will be interesting topic.
All the best!
