Pulling apart Revo3 dsv

diverdman · 22nd November 2009, 07:32

My new Revo 3 has a very stiff on off action. So I have attempted to pull apart to lube up.
Removed the on off knob and flapper valves but for the life of me I cant get the barrel out to lube it.
Do you remove the barrel in off or open position???
Any tricks I am not aware off.
I gather a hammer and screw driver is not a good idea.
I am going to try warming it up under warmish water and see if I get any luck.
Help appreciated.

Give Geoff Stebbing a call. Been pulling Rays apart for years. Has a few DSV's on hand and he can show you how to service.

Cheers

Hi Damien,

I did that two days ago as my DSV was also very stiff.
Just use the handle of a screw diver big enough not to damage the inner barrel.
Close the DSV. Push a little bit to let the outer o-ring appear then take it off. Push on the opposite side and take the barrel out gently.
Use O2 grease and put a fair amount on the o-rings. It should be easier to manipulate.

at the moment we are testing out a modification on the standard DSV, that makes it working super smooth all the time, and will prevent getting small dirt/sand (from cave diving) sticking between barrel and outer housing
modification can be done easely by the user himself
will publish it when w're sure it does not have negative effects

Thanks all used a broom handle with some tape wrapped to get the right diameter.
Took a lot of effort but it came loose and one outer oring is now in 2 pieces.
The inner bore on the DSV looks like it has been attacked by gremlins with mini chainsaws.
Will be getting a bag of orings to fit but would not recomend you pull apart your DSV unless you have these and want to go diving the next day.
I look forward to Pauls resolve as mentioned below.
I think I probably need a new inner sleeve on my DSV for it to function smoothly.
Mind you the Revo and DSV is only 6 weeks old and cleaned very well after its all of 16 dives in non silty conditions.

we do know that if anything get's stuck between barrel and outer housing, it will scratch the barrel, not the housing (that is the purpose: housing is GF re-inforced material, barrel not)
solution, very fine sandpaper, clean it up a bit, the sealing is not on the surface of the barrel, but the O-rings, so no problem
will look up the O-rings, we have them as spare kit
are you sure only 6 weeks old, Damien?

Confirming Paul's point -- see attached photo of when I pulled mine apart last week. I used a method similar to Stepane's to get the barrel out. IT was very stiff and could not close DSV without two hands, and then it was really hard to close..

After I got the barrel out, I notices the scratches on the barrel, but the DSV housing was smooth as could be and not a scratch on it.. Little sanding on the barrel, and smoothed it right out..

Re greased the O-rings w/ Trib-0-lube, and now smooth as butter..
Still not sure how I got the debris in between the Barrel and the Housing
