SP Mk10 annual kit

[dhillman]

Hello to everyone. This is my first post. I had a not so good experience when I sent my Scubapro Mk10 firast stage regulator for annual care at the dealer. The regulator was leaking through the swivel so I decided to open it. I found the blue swivel O-ring cracked in many areas. I replaced it with a similar black O-ring. I downloaded the schematic for the Mk10 first stage, but I am looking for the repair guide and also for the annual kit parts. Is there any place I can get that kit? Is it still available? Thanks for reading.

The kit is available on ebay, and at sympathetic dealers. The o-ring you're talking about is a number 017, and should have been replaced at the annual service. Couv has a nice annotated schematic in which he has listed the generic o-ring sizes for all the o-rings on the MK10. I'm sure he'd be happy to send it to you, or send me a PM and I'll send you it.

I don't know if I've ever seen a repair guide for the MK10. It's a pretty simple reg, and the Vance Harlow book does a good job of describing the rebuild for it.

One thing I have found that helps the MK10 with IP stability throughout the supply pressure range is a true 90 duro polyurethane 010 o-ring for the HP piston. You can get those from oringsusa.com.

Thank you Mattboy. In fact I replaced it with a 017 O-ring at a Hydraulic shop. I am very interested in the schematic with the generic numbers conversion. How can I get a copy? Also I noticed that the lubrication for Dynamic O-rings should be the Christolube MCG 111 which is quite expensive at Scubatools. Is there any other alternative silicone? I am ready to place a big order including several tools from Scubatools.

I ordered the book on friday so I think I will be pretty much set-up. Looking foward to dive this Thanksgiving weekend.

Thank you again Mattboy.

While you are ordering at Scubatools, check out their book "Regulator Savvy". It gets deeper into the science of regulators, the physics that make them work than Van's book does. Van's book gets deeper into the servicing of regs. Using the 2 books together, you get a really good understanding of how regs work and how to service them.

Cristolube is expensive but a small tube will last the average DIYer a lifetime. I have seen small 1 oz containers of it, they are not too bad and more than enough for the DIYer.

Maybe this new stuff "Tribolube" is a little cheaper and it seems to be pretty good. A guy that works for the company that's making it was posting for a while and nice enough to send a few of us a trial tube. I've been using it. I'm looking for a SPEC boot for one of my MK10s to try packing the chamber with it.

You can use silicone to lubricate the o-rings in your reg. In fact, you can use it and technically still use nitrox to 40%, although most people are using O2 safe lubricants for all regs regardless of O2 exposure. Silicone is considered a risk in high O2 environments due to flammability. The consensus is that Christolube is a better lubricant overall.

Hello DHillman,

Welcome to Scuba Board and to the DIY club. Below is my standard cut and paste advice on regulator self service. If you send me a PM with an email address where you can receive a PDF file, I will send you a copy of my annotated MK 10 breakdown. Additionally, please read the Sticky Post at the beginning of the regulator forum re: regulator inspection.

Servicing your own regulator:

Welcome to the DIY club. The first thing is to start off with a service manual or two. Both service manuals usually discussed here are great; Vance Harlow's "SCUBA Regulator Maintenance and Repair"
http://www.airspeedpress.com/newregbook.html​

and the Scuba Tools book, "Regulator Savvy" http://www.scubatools.com/ are well worth the money.
I own both and recommend getting one of each. If you are dead set on getting only one, then Vance's is a little more suitable for the DIY guy while the ScubaTools book is more suitable for the shop worker. ScubaTools has some pretty handy tools too, so if you order from there pay a few extra bucks and get the bullets, spanners, and regulator specific tools that you need with your first order and save on shipping. Get a few old regulators like the ones you will be servicing from eBay or Craig's list and practice. After just one or two seasons of servicing your own gear, you will have recovered your investment.​

Here are a couple of websites with tons of regulator specific manuals:

Good luck,

Thanks again to all , I want to be sure evreyone of you can read how grateful I am for all your quick and knowlegable answers. I have read about the issue that a Regulator is a life support equipment and that it should be only taken care by a certified technician. Although I am not a certified technician, I get deeply involved in all the things I fixed. I am a dentist but I love to fixed everything around me. I have a shop at home and was also grown with a mechanical engineer (my father) also having our own shop at home. I'm saying all this bluff to let you know that I won't let you down with fixing my own regulator.

I am glad I was not the only one with this problem of sending the regulator to a professional and not having the right job done. Thank you again, and anything I can help you with, please ask.

I started diving in 1977, but there was a gap between 1997 to 2008 that I only use my gear for cleaning up the hull of my boat, so I am kind of rusty. I started this summer with some spearfishing and U/W Photography.

Thank you all again, very very grateful.

Regards,

Darrel
