Halcyon H75P + Halo (weird?) cranking effort

[estresao]

A few pages back, there was discussion of possibly the O-ring for the poppet (?) in the service kit being a little too big.

Is it possible that that is what is going on here? Maybe Halcyon got a batch of service kits that have an out-of-spec O-ring for the poppet?

Yes, it happened to me that on the beginning I was using some "compatible" maintenance kit and, after several test I've found these o-ring were a little (very little) bigger than the original, so I bought Halcyon original kits and got a very good cranking effort.... but now, after some adjustments I wad to do with the IP, I'm no longer able to get the (near) 1 water inch cranking effort.

BWT: I've opened this post and most of it were referring to my regs.... the same today are driving me crazy now.

have you checked the lever height? Does it rattle when it’s pressurized?

I did... I think it's OK. I don't notice rattling.

So you shake the 2nd stage and it doesn’t rattle that’s good. How was your your level of purge? How far do you push in the purge button before it starts to purge?

None of my Halos have a violent free flow either when purged either. I'm not sure what the reason for that is.

Out of the five, the two that have high cracking effort do you notice a difference in purge?

Yes. I if I adjust them so that they're just barely leaking the purge is not as good as the others still. Subjectively at least I don't have a flow meter.

Has lever been bent?

Compare levers.

Compare levers.

I will when I get them back, but honestly I'm not really sure what dimensions I'm suppose to be comparing

Remove the cover and diaphragm. Measure with a straightedge from case rim to the top of the lever. See if they’re the same.
