Opening a DS4

Mossyback · 17th August 2007, 20:06

I've just received a blanking plug for my Apeks DS4 1st stage. Before I operate with a hammer and chisel, how does one open it and insert the blankings plug? I'm assuming that the chrome ring with the semi-transparent soft end is removed (somehow). Does it go back on after the blanking plug is installed?

Pin spanner, I think it is either 40 or 42mm.

Hank,

How far are you from Dive Tech in Mallorytown? The boys will look after you there.

Cheers

Use ring spanner to remove the top chromed ring. Remove the environmental seal. Put the delrin plug inplace and tighten up the ring again. There is supposed to be a radial oring sealing between the plug and wall of the DS4 so no mega torque needed.

Great link the important parts for Hank are below
-Get a 7/16 bolt into the port of the DS4 so you can clamp it in a vice
-Remove with a pin wrench(spanner) or I've been able to do it with a rubber strap that allows me to grip the chrome top

Hank,

Practical advice:

Screw a C02 cartridge into one of the LP ports (a used one is better but a full one works).

Gently clamp the "part that needs to come off" in a vise.

Use the C02 cartridge as a handle and unthread the darned thing.

You'll remove the existing crap (diaphragm, plastic bit, and pin) and install the plug.

I screw the "part that needs to go back on" on hand-tight. Remove it now and then and wash out the salt that will get into the regulator. Yes, I *know* it's supposed to stay dry... but after a year it will be wet.
