Rebuild Typhoon lpr reg?

WilD · 03-15-2007, 09:24 PM

The reg on my Typhoon is leaking and I'm trying to decide if I want to try rebuilding it myself or send it to PPS. This is the older style rock too (sub 300 serial number Typhoon). I'd appreciate hearing oppinions from those who have attempted to rebuild rock regs. Thanks.

Does it leak from mostly front of lower tube, or does it have a 'middle of the marker' leak also or instead?

If it's leaking from the overpressure relief, then it's the LPR piston o-ring. Rebuilding the LPR isn't a very difficult task. The O-ring is a # -112 I believe (I'll double check that and get back to you).

It leaks like crazy from the middle of the marker by the ASA. I suspect it may be the over pressure relief, but not really sure. The leak can be turned off by adjusting the rock pressure all the way down, so I know its the reg.

If its over pressure,piston seal,then it should be leaking out of the adjustment knob,not by the asa.

Ok that is probably the LPR body front oring, the alumn body behind the LPR piston. The air pressurized between piston and body, sneaks around it and shows up as a 'middle leak'.

This is of course that your UEF fitting and hose is ok there first....

That phoon is old enough to consider a full rebuild. I just did a hurc form 1991, it gets scary in there after 15 or so years.

Is there a diagram or exploded view someplace I can see? I'd prefer to just replace the seal myself if it isn't too hard to get to.

Do a quick search for Jay Beam's exploded Hurricane pic. I have it somewhere if you can't find it, but I see it all over.

The trouble with that pic or any exploded diagram you are liable to find is that these are hand made guns.

If you have an older Typhoon, there is a considerable variety of bit that can be found within that lower tube. Similarly, if you have a newer Typhoon here (the LPR and such had been pretty much standardized by the mid-90's) it will not look like the guts in Jay's Hurc pic as his is an old one.

That said, crack her open and keep track of the order in which things come out. Even for a dolt like me, there is a certain amount of logic and common sense involved in the layout of the LPR guts.

Good luck and keep us posted.

there are 3 different insides. Jays is the newer style middle, older style front, an Elite hurc ified with a 4xx serial range.

If I remove the lpr output hose fitting, will the rest of the reg body just slide out the front?
