so, I was doing a service on three 2nd stage Atomic regs. Ti2, B2, then a Z2...
no issue, with the service of Ti2, but when I got to the B2, the poppet spring appeared to be longer. I was doing them all concurrently, so remembered.
when I got to Z2, I noted that the spring was the same size as the B2.
I looked at the exploded diagram, and cannot tell from the drawing how many turns the spring is suppose to have and they all have the same part number.
when I got to the 1st stage and removed the small spring (the one that has a diameter slightly larger than the shaft of piston, it dawned on me, if a service tech took apart both regs and got the springs mixed up, they could have put the wrong springs in each reg...
the part numbers for both ARE different. the springs in the 1st stages were identical.
since Atomic 2nd stages have variability in the adjustments in the spring pad and orifice, I might be able to get cracking effort in the acceptable range.
that begs the question though, composite of spring materials, lifespan, wear on other components, force required to push spring, etc. can have unknown consequences.
I'm servicing the regs for a friend and don't want him to get hurt. I don't know that the spring installed is not the correct spring, or was at some point in the past, either.
I don't work for an Atomic retailer so don't have access to their service department and even if I did, I'd have to find a tech with 10+ years of experience as the regs are that old (at least)... BTW, I have worked for an Atomic retailer, where I learned service, I have the proper tools and gauges, and use genuine parts.
(this is the poppet spring)
(this is the spring I believe is not right)
(this is the spring from B2 and Z2)
(this is the spring that I suspect it is)
thanks for any feedback you can give.
