Oceanic Rim Clamp Alpha 7

The Oceanic rim clamp is designed to assist the technician in removing second stage diaphragm retaining rings that can not be removed by hand. This clamp fits the larger Alpha 7 Oceanic second stages that utilize a plastic rim. It will not fit the metal rims used on the Delta 3 second stage. The clamp is used by pressing the rim all the way into the clamp until the rim is against the recessed ledge. The clamp is then positioned in a bench vise with the split side of the clamp between the jaws (see left illustration). When the vise is "gently" tightened, the clamp squeezes the rim evenly around the entire circumference. This uniform pressure firmly grips the rim without distorting the second stage housing. The second stage housing can now be used to dislodge and unthread the rim. The Oceanic Rim Clamp is machined from aluminum alloy and vibratory finished. Instructions are included with the clamp.
