Help Identifying a Sherwood Regulator

[jacked_72]

I picked this reg up today along with a US Divers and I'm trying to decide which would be the better set up to put the money into to rebuild. I think the answer is going to be the sherwood because it is complete (primary, adjustable secondary, octo and old computer) but I'd like to find the model name and whether parts are still available. I think the reg is about 15 years old.

I'll post about the US Divers sperately.

Thanks for the help in advance.

I used to repairs these. The secondary is an older Brut-style (very easy to service) and the other is an adjustable Maximus??? I wasn't too crazy about the primary because it was more complicated than it needed to be and had to be routed under the arm which is a tad goofy.

The gauge is no biggie really. Sherwood made a pretty cruddy gauge which often went belly up with moisture getting inside. The Tekna timer is pretty cool and the computer is no big deal to service either. The first stag is a simple repair for a tech.

...are you going to rebuild it yourself or have a local dealer do it ? Your local dealer can tell you if Sherwood still supports this unit......I'll bet Sherwood does.......but it's not always easy for a retail customer to get parts, the dealer will likely insist on doing the work for you and not sell you the parts. Also, without opening up the unit, it's hard to tell the inside condition of the unit, especially the 1st-stage. Also, it's easy to sink enough $ into a rebuild to exceed the value of a new reg.....or a barely used much more modern reg....so be objective before you get too excited about your big score.

My plan is to have a shop service it, but I want to educate myself about the reg before I take it in. I'm expecting to pay around $100 for service and parts whatever setup I buy and for what I paid, its still a good deal, but if its too much more than that, I agree new or newly-serviced may be the way to go. I like the idea of the adjustable secondary, though. It may be some early Maximus, it looks like some of the pictures I've been able to find, but nothing quite like this. I can't even figure out where the purge valve is.

Are these thought of as good regulators or is it the combination of the primary and secondary that determines what's good and bad (in addition to personal preference)?


Thanks.

Both AquaLung and Sherwood are long term proven equipment - and you can get service anywhere in the World. I dive Sherwood while my dive instructor son uses AquaLung.

If you like the "pink" - you really can't go wrong getting the Sherwood serviced. It will last you forever. The Sherwood Brut is used all over the World as bulletproof rental gear. If its the Oaisis - well it's the next step up.

If you paid $150 or less, you got a good deal. However, it will cost you to get these serviced by a LDS tec - and you must get these serviced!

The Brut/Magnum older style reg was pretty tuff...I still use them from time to time. They are easy to service and a repair tech would probably replace a rubber seat & diaphragm in them and inspect to see how much wear and tear + corrosion.

That Maximus was Sherwood's attempt to create a technical-style, or high performance regulator. That weird shroud covers the purge valve and it is adjustable (picture)... - it will require more work. I really thought they were a convoluted design and stunk because of the underarm routing.

The first stages are pretty bulletproof. It'll be a simple look inside at the condition of the piston, rings, high pressure seat and water test to see how well and how much it's bleeding out gas through the rubber release. As your rig looks pretty clean - let's hope it's the same inside and lightly used. Changing pistons, springs, adding shims etc. can get the price up.

That is the "Darth Vader" Maximus. There were quite a few out there, bought by people who had to have what was then "Top of the Line". It was produced late '80's-early '90's and had the same first stage as the Oasis and Blizzard of the era. As said above, the second stage was needlessly complicated and the adjustment was not very effective. But, it was a very reliable regulator. The first stage was one of the models with the dry bleed filter in the piston, requiring a piston replacement if this scintered filter is blocked. But, if this filter is ok and the rest of the internals are good, the rebuild should not be too expensive.

...also remember, even the rubber hoses are 15 yrs old and may be due for replacement...you don't know how many miles the unit has on it.....or if it was stored in a hot/ozone/UV light environment (bad for hoses) and a weakened hose blow out at depth won't be fun! Replacing 4 hoses ( 3 LP and 1 HP ) even if it's the 'cheap' rubber ones (and not the cool new MIFLEX ones) will run you $ 15 - $ 20 per hose. ....again, be careful sinking $ 300+ into regenerating a $ 25 reg.
