STEYR LG 110 Regulator advice

Hello Tom. Have you made a video on a regulator rebuild yet? I'd be very interested.

As stated a few posts up ... The 2 hole cup is JUST there to open the tubes check valve. Once out you will see a small screw driver slot that is the top of the seat height adjuster.

With calipers MEASURE how far down in the hole it is sitting and write this number down. Now unscrew it CCW and remove it. This is where you will find the very small o-ring that can allow bypass air going around the seat. If this o-ring does not have integrity your pretty much screwed.

Hi. May I ask if instead of measuring the depth of the screw with a caliper, to screw it down til it touches the delrin and back off half a turn? I failed to measure it the first time so I am left wondering what to do with a creeping pressure.

Just like doing so with a HUMA reg .... ROTATION of the SEAT against the sealing disk by bottoming them out mechanically .... Dents the seat and damages it.
You take a VERY larger chance of screwing up the seat and creating a creeping set point / poor stability situation.

JMO ...

OK. What's done is done. May I ask How I can remedy the situation? When I screwed it in to basically touch the delrin, it was a very soft "touch" as I was consciously just trying to feel it.
