Promaster dilemma

[Razor*NOR*]

Now that I have tried my PM, I was really suprised, the gun shoots as a timmy at over half the price!

But, when I played I bumped into a problem:
Suddenly it started to leak as if the LPR was set to high, so I backed it down a notch. But that created another problem, the bolt didnt go back far enough after each shot to let a ball drop in the breach! So, im sitting here with a PM who leaks if I up the LPR but wont let balls down the breach unless I do!

i.e Help !

What's your HPR at?

[manike]

Possibly an o-ring seal in the LPR. Lube the LPR with dow 33.

[Razor*NOR*]

HPR is at 250. So I just disassemble the LPR and lube it?

[manike]

Yes, with dow 33 or maybe even 55. A little o-ring swell may help.

IF the LPR is leaking it's one of those o-rings that needs fixing.

[Razor*NOR*]

Sorry guys, have to up this again....
Gun still wont cock to the poing of letting a ball down without leaking. The LPR has been totally stripped and relubed, with no signs of improvement... :confused: The leak is internal, not coming out in front of the LPR.

Please help me, I dont want to be stuck playing with a 4 pound cocker!

when you push your bolt forward does it temprorarily stop. I have a problme that is similar. I used to be able to push the bolt forward a bit. That would stop the leaking. now its getting worse.

any thoughts manike. ive completely dissasembled cleand and relubed the LR and well. i think it could be the cupseal. Or this is what i have been told. But idk what that i or how to fix it.

thanks

Yup, it stops when i push the bolt forward.

alrihgt. We have the same problem. I warn you now. Dont play wiht it like this. It goes from a small leak, to a big leak after awhile.

I cant play with it, the bolt wont retract enough to let a ball down the breach.

o. your HPR is too low. set the lpr rihgt and turn up the HPR till it cocks. Thats an easy fix. I just want it to stop leaking.

[Razor*NOR*]

Not sure about that, the HPR is at 250. It worked fine the first half of my last practice, then it started acting like this....

[manike]

Open the gun up and check the hammer is tight on the ram... sounds like the hammer might be unscrewing from the ram...

[Madpooh]

dwell...

[Razor*NOR*]

dwell...
I ahve tried stock 8 and 10. Still teh same. Opening her up now....

[PhattyMcPhatt]

dwell...

I've tried all the way from 6-12 and mine still leaks, I've tried turning screwing the hammer all the way in and adjusting the screws that hold the ram to the body, tried lubing the ram shaft and mine still does it some times it stops when I push the bolt forward and sometimes it leaks worse :confused:. I just know I'm not sending it anywhere until Oct. because then I'll be to busy hunting to play paintball so I can be without my gun for a month. :D

If this can cause what I describe, then it might be fixed now... The hammer was 3-4 turns unscrewed, and the red loctite they used at the factory had dissolved... I put in some green industrial loctite, and I am now crossing my fingers that it will do the job.

[Madpooh]

well, you still have to lower the lpr when you raise the dwell

[Coolmarve]

Yea, thats what happened to my pro and once I loctited the hammer in, and got a ram bumper on there, it worked like a charm. Seems like a little bug in most pros is that they didnt loctite the hammers on, causeing this problem in soo many guns.

[MajorPaynt]

ram bumper???? Whosamawhatsit???? What,where, and why please.

[ICD-EVIL]

yep mine was off too. this must be it. lol, and i found like half a paintball in my lpr. wow

I <3 red loc tite

[Coolmarve]

lol

@coolmarve
What is a ram bumper?
Where can I get a ram bumper?
Why would I want a ram bumper?

Please.... :D

[ICD-EVIL]

when i got mine it worked perfect. i mean incredible. Then it started to do this. and eventually got real bad. so i guess it gradually coming off would explain these problems getting gradually worked. So if it is now back like it first was it should be wonderful again..

[Capital Paintball]

Definatly sounds like the hammer unscrewed from the ram. locktite it and wait a few hours before you gas it up.

[Razor*NOR*]

Tried it and it works like a charm :D

[manike]

:D Glad to hear it.
