DACOR PACER Manual

[shogan]

My pacer 2nd stage is free flowing (not even in the water). Havn't used it in years.

Anyone have a manual on it.

Don't think it's worth the shipping to get it serviced!

There are ten sections in my Dacor repair manual for Pacer second stages:

Pacer Second Stage
Pacer Aero
Pacer Gemini XP alternate
Pacer Gemini XLP alternate
Pacer XLE / XLT / Ice Pro / XLE AER
Pacer XLS (metal)
Pacer XLS (plastic)
Pacer XLB
Pacer XLP / XLPG
Pacer Formula / XP / Ice / Dry Ice

I occasionally scan sections of the manual for folks such as yourself with an established presence here on ScubaBoard. My free-ware pdf maker is very slow and labor intensive, so I need more detail of what second stage you have.

We can probably eliminate the two alternates because they are just left mount variants of other second stages. That leaves eight to choose from. If you don't have your owner's manual, or other definitive information, a good picture would help. Or PM me and we can exchange descriptions until we've narrowed it down. After we've established what you need, PM me your email address (don't post it here) and I can send you the scanned section of the manual.

By the way, you might get more responses if you ask a mod to move this thread from the Tanks, Valves and Bands forum to the Regulators forum.

The Pacer is a simple second stages so repair is no problem even without a manual. Before you go too far, I would suggest you first check the IP of the first stage, there is a fair chance the problem is your first stage and not the second. No need to chase the wrong problem.

Are Dacor parts even available these days?
I have a really nice 960 that I retired as I could not find anyone to service it.
Have "work-arounds" and parts been figured out by some folks?
Thanks for reading.

Second stages are no problem, all use pretty much generic parts with the exception of a few later diaphrams but those rarely go bad. The first stage are more of a problem. I know of one shop who has a few old parts. As long as the HP seat in the 960 is good...and if it's not creeping it's OK, then the reg should be good for a good many more years if you take care of it. Any O-rings are generic and the diaphgrams are fairly easy to substitute if you do the work yourself, no shop will likely do it because of liability issues.

They recently did a Dacor rebuild for a friend.

Just realized I posted in the tanks section but hey thanks for the responses.

It just says pacer totally balance here is a pic. Sorry don't think it came with a box.

Well I don't yet have a pressure guage to test IP but can tell I will be ordering 1 soon.

Yes when I put the 2nd stage on a different first stage (recently serviced sherwood magnum) it works fine without free flow.

Thanks

Good pictures. The pattern of holes for the exhaust valves pretty much confirms that you have the basic Pacer. I've already scanned that portion of the manual for someone else, so if you PM an email address I'll be happy to send it to you.

IMO all divers should have and know how to use one. But before totally blaming the first stage, if the freeflow is slight, it may still indicate a tuning issue with the second stage and not a first stage problem. If your Dacor first is set near it's max IP range- 140ish and the Sherwood is set on the low end 130 or so then it's quite possible for the second stage to slightly freeflow with one and not the other.
