Shopper Can someone point me in the proper direction to attaching this to my current first stage? removing the current Yoke valve and putting this into place? I've looked everywhere. Thank you
SHANE T I own one of these. As far as I know it's only for the bleed valve style 1st stage only. It does not fit the SR1 or the GR450 currently being sold with sherwood until they fix the SR1 problem.
It's easy just take off the nut counter clockwise that holds on the yoke. When that's off just thread on the Din conversion and lightly torque it on.
Marilyn S From Sherwood Scuba: Any authorized dealer with an in-house technician will be able to help with your request. Service technicians are the only ones authorized by Sherwood Scuba to perform those kinds of installations. Removing and replacing Yoke to DIN is a task that requires specialized tools.
User N PS Daniel C, I have a new Magnum 1st stage. Thank you
User N Thank you all for the help!
BRIAN A Remove the nut that attaches the yoke on and the din will screw right on to the first stage.
DANIEL C Additional info: The 1st stage body is machined as one piece with the threaded outlet where the yoke or the din adapter goes. You can wrap the 1st stage body with tape to keep it from being scratched, then clamp it gently in a vice with the yoke on top. If you use a very large crescent wrench you will turn the yoke so that the wrench slides past the edge of the yoke to get on the large retainer nut, so a deeper wrench is preferred here. I do mine with a box wrench with the sides ground thin to go from inside the yoke, but the crescent wrench is easy to buy.
DANIEL C I can't answer without knowing brand/model of your first stage. This is for Sherwood 300Bar rated first stages - mine is a Maximus. A wrench (1 inch as I recall) removes the big swivel nut which retains the Yoke. Once the yoke is off, there will be a fine threaded shoulder where the end shown with the hex nut here is screwed onto the first stage - make sure there is a small O-ring in that end beforehand. A larger O-ring goes in the end that mates to the tank. DO NOT OVERTIGHTEN.
LUIS R First, you need to loose the big nut that is holding the yoke to the first stage. When you take out the yoke simply put the conversion kit where the nut was.
BRIAN T HI THIS IS VERY EASY TO DO. JUST UNSCERW YOUR LG YOKE NUT AND SCREW IN YOUR NEW DIN ADAPTER. THANKS BRIAN.
KASEY C You pull off the yoke and put this den one In its place
PETER F then end of the yoke that attaches to the first stage has a thin hexagonal head just below the widest end of the yoke. you'll need large 10 or 12 in crescent wrench to get the yoke bracket off. i placed the 1st stage in a vice, yoke up with the connect exposed then it still took quite a bit of force. i really thought i was breaking it. in the end it probably would have been easier to have my shop help me and direct me through it or do it for no cost. when you put the din converter in, it tightens via allen wrench in the hole with the o-ring.
