Parkway first stage service manual

[emoreira]

Hi people, I was given this old Parkway first stage. The guy that gave it to me said that it was blowing bubbles by the holes where it sens the ambient pressure.
I will try to rebuild it. If any one has the service manual and any idea of which model is it. Thanks.

Sorry.

Finding one may be a hard sell, since Parkway has been toast since 2003; though someone, here, is bound to have a PDF on hand . . .

Looks like a MK-5 clone

Looks externally not unlike a ScubaPro Mk V or its many piston clones. Any number of such manuals may provide good guidance. What sort of HP seat is inside, may be the only significant question.

Good suggestion. Do you have a copy or access to Harlow's Scuba Regulator Maintenance and Repair? It covers any number of major brands, though the late Parkway, specifically, is not among them; but does feature Scubapro models.

It also has a chapter on making various custom tools, including drifts . . .

Disassembled and cleaned. Now getting the o-rings. Very similar to any piston balanced first stage.

Does it take a generic MK5/10 seat?

The HP seat was perfect, so I do not need to change it. Besides, I do not know the seat of a MK5/10. Sorry.
