mk10

I have several MK10s to service. I have come across a few comments here and there such as: Remove the polished surface from the piston stem o-ring. Micro-mesh the piston hard seat. These comments were made as modifications to try. I don't know what they mean or what improvement these...

I was working on designing a piston o ring bullet today and they have a really small base. 4.3mm. I was using a 10mm brim at .1mm thick. Looking at the brim after taking it off the bullet I thought it looked a lot like the shims that were in the regulator. Thickness seemed awful close...

Howdy folks, So, my "mint" MK10 eBay purchase turned out to be MK10+. No IP creep and holds a good 130PSI IP with one shim. Looking at the reg - it was used lightly but never really serviced. Will need O2 cleaning and a rebuilt, as I am planning to use it on my bailout paired with a 250...

I need to slim down my collection of regulators. Here are two MK10s. #1 is slightly nicer. #2 is marked with 49. Both have the thicker yoke. Aside from wiping them down and testing them on a tank (they work) I don’t have much info as I got them as part of a bigger purchase and just don’t need...

I will be grateful for advice on my plans regarding first stages. I am joining the regulator self-service club. To keep the maintenance easy, I am switching over from Scubapro Mk25s to semi-vintage Mk5 and Mk10 first stages. I have two Mk5s, one with a thin all-metal yoke and one with a thick...

Scubapro MK 10 and G250 rebuild. Diving again after decade layoff. Got MK 10, G250 and R 108 serviced at LDS and they did a less than stellar job. LDS complained that I should not be diving with such old equipment. Charged me almost $100 for service. Said that my MK 10 “creeps” but was within...

Hi, I'm looking to work as an instructor soon (full-time warm-water) and after getting a bit deeper into the technical side of regs etc. I'm wondering if it would make sense to get a cheap (~55€) used Scubapro MK10 (+R190) set instead of my current Aqualung Titan LX (pre 2008 model, bought new)...

Hello Fellow Divers and Dive Professionals! Recently i've received this beautiful piece of equipment from my mentor. It came with a Scubapro 108 second stage. I've personally serviced both 1st and the 2nd stages. Found no major issues... Until i went to test it on a full tank. I seemed fine...

Hi all, Was doing some servicing on a few regs last night in preparation for a trip. I've set the IP of all regs to about 150PSI but when testing the dynamic IP (using a gauge on the LP hose) I noticed a big change in the pressure drop when purging the regs. My Diaphram first stages (Poseidon...

I was looking for an annotated MK5 Schematic and couldn't find one. So I decided to annotate a MK5 Schematic starting with the annotated MK10 Schematic previously posted here on SB as a reference point. Since I had to identify some of the SP o-ring part numbers on the MK5 schematic that are...
