Hi all

 

I need help with my hugtfot d7000 and 20mm. extension port that stuck in front of the housing and cannot take it off!!. I try many ways to remove it but not work.

Thank you in advance.

Hi - my strong advice is to put the dome back on, which you can then use as lever to rotate the ring off.. Eventually the ring should move. If that fails, then take it to a dealer - don't use any other tools or you'll damage the ring or worse, the housing.

Hi Scuba _ dog
Thank you for your reply. I trt to put dome on and that doesn't work for this case. Actually this part was stuck in my housing for month and i worry that it wilk cause laeking and flood my housing one day. I try so many way to remove it even buy port remover from divervision (see pic below) and that doesn't help me at all. I'm leaving in Thailand so send the housing back to Belgium is quite expensive. I just curious that do people who owned hugyfot housing dosen't have this problem? Or they have but can figure out the easy way to handle it.
If anyone have this problem and can fix it please share your way to me.

I've never had this problem, but I would assume it is seized due to dust/dried salt in the gaps between the extension and housing. With most things that are seized in place, adding a tiny bit of WD40 help to create lubrication 95% of the time works. 

 

I imagine as long as you gently fill the open port hole with cloth - say a tshirt etc (protect the inner workings), and spray the wd40 gently and sparsely around the outside of the extension/housing where it screws in, it should be ok....

 

I have never had this issue, not have I ever used WD40 on a housing, so maybe wait for some others to answer first.

Thanks swgdesign for your suggestion. I'll try and let you know.

A few thoughts tapitt

 

I wonder what has caused the problem. Maybe, as swgdesign suggests, it's dried salt. You could then try soaking the housing/port seal area with a mix of white vinegar and water (say 50/50) overnight - and see how that goes. The vinegar is usually easy to find in a supermarket and very cheap. You may then want to replace the port o-ring as the vinegar might weaken it. Not sure if WD40 will soften dried salt - but it is a bit of a miracle worker so worth a go. Again, might be wise to replace the o-ring after.

 

In either case I'd try and minimise the area that is soaked by the vinegar or WD40.

 

The other thing you might try is a something for vehicle maintenance such as an oil filter remover (if you google that you'll see what it looks like). You might be able to take your housing to a garage and they might be able to do it for you - or lend you the tool for a few minutes. You may well want to wrap something soft around the port to protect it from damage from the tool.

 

If the vinegar or WD40 doesn't shift it, the garage tool should do the trick. But if the problem is that the port is cross-threaded (it doesn't look like that from the pic) using the garage tool may well crunch the housing thread which would be, errr, less than helpful. If you think it is that, and sending the housing back for maintenance is problematic, I'd suggest talking to a reliable, truth-worthy mechanic and see what he reckons.

 

Good luck!

Thank you all to helping me for this problem. I just finally removed it!!!!!
By use old bladder rubber tighten around the extension port.
But this not solve my problem last long.
Still wonder what's wrong with my housing.
Why this just happen to me only. Hmm curious.ed6d9553cdb209eaf4147b46a2f506f2.jpg85d95224d3331da10f841227a54afe79.jpga0d62a20fe123f4fc062b46738d0f69b.jpg

No worries, tapitt

 

I hope you can get it sorted out quickly and simply. It sounds an utter pain!

 

Best wishes

I had the same problem a couple of years ago (with the exact same housing and port extension). I gently used the same rubber band trick (oil filter tool was too small). Since then I make sure to lube the oring every time and remove the extension ring immediatly after use. Never had the problem anymore since then.

Then i try to remove port as soon as possible to prevent this problem but sometime after finished dive i have to drive 3 hours back and may not covenience to do that.
Anyway thanks for your suggestion jefdriesan

A couple of hours is no problem. Just not days (or longer than necessary).

I have that problem a lot with my Sea & Sea port extensions.  I used to use a giant channel lock wrench cushioned with rags, but have since got a rubber strap wrench at the local hardware store that works quite well.  I take it on all my trips with me.  Plastic handle, long rubber strap folds over.  Trigger tightens the strap, then you just bend it left until it breaks loose.

Great to hear that just not me facing this problem also thank you for your tip Larry C.

The best tool to use is called a "strap wrench"

It uses a plastic or reinforced rubber strap to go around the cylindrical object and is the least damaging tool to use for this application. Usually available in auto parts store. I carry one with me on all trips. Handel has been shortened for eae of use and packing.

This is the one I use, though I bought it locally, I think at Home Depot.

I get exactly the same and treat it exactly as Larry has, sometimes a wrench in needed some not.

What I found increases the problem, is leaving the ports or rings in situ for multiple days. I'm just glad the fit is so perfect that's it's making a good seal lol. Using bad language and calling it names also helps I find !!! Lol

I think that the problem is that the lubricating grease can get displaced away from the sealing 'O' ring when pressure reduces leaving an 'O' ring rubber to metal/plastic contact only. When this happens the resistance to the rotational movement required to remove the port is vastly increased as there is no lubrication and as stated it can be very difficult to remove the port (I've actually used two substantial policemen to do so, which worked a treat but policemen are rarely around when you want them ;)). In my experience, as Craig says, leaving a port or extender in place for many days and dives seems to make things worse - probably by displacing a little more lubricating 'O' ring grease on each dive as pressure reduces and increasing the area of rubber to metal/plastic contact. I have a strap wrench now too for this problem.

Funny that, Paul. Every time I drive to North Wales there seems to be police on every lay-by. With speed cameras.

WD40 DESTROYS O RINGS !  Check this by putting WD40 on an old O ring, it will swell and degrade.  

 

To loosen a stuck port, I would try the vinegar as suggested.  Another approach would be to put a solution of vinegar and liquid detergent on the crack between the port and housing, wait some hours, then use the strap wrench.  I carry a strap wrench during trips as it is often necessary to remove ports.

 

After a dive trip, I seal my housing and immerse it in a tub of water with vinegar, leave it overnight, then rinse it with water, dry and take it apart.  I store it disassembled, with the housing back and front separated, the ports off, so as not to compress the O rings..

 

When installing, first I clean the O ring grooves, threads and bayonet mounts, the I apply a very light coating of silicon on the O rings.

 

Good diving!
