WDP and their lousy quality control.

[Major Morningwood]

I just picked up an angel tool kit to install my evolve v2 kit. Mind you my speed 05 has never been modified, nothing else except for a volumizer, I run a LP crossfire tank and my fps is around 260. I removed all the volumizers and the cap over the LPR and I installed the angel gauge. As soon as I gassed the marker up I like to fell backwards. This thing has been running at 120 PSI on the LPR!!! No wonder I have been chopping paint and shooting breaks. I used the LPR removal tool and found 6 shims installed. This gun was bought new so it is not from someone else tinkering. I removed all the shims to see what it got down to and it hit 80 PSI at the lowest with no shims. I thought the MT's were saying you would have to add shims to get to 65 PSI this is awful. Obviously WDP has shipped my speed with a faulty LPR. When I started rapid firing with the LPR at 80 psi and no shims it got two shots out before the bolt started acting like it was starving for air and the gauge was reading 20 psi and slowly going back up to 80. I reinstalled two shims and once again I was back at 100psi. I fired rapidly and again it started sputtering and the gauge was rapidly dropping with possibly no more than 8bps trigger pulls. Re-installed all 6 shims and finally got the gauge to barely move more than 10psi, but something is seriously wrong with this angel. How many of the rest of you have tested your lpr and found extremely high pressures out of the box? Maybe this is the problem with everyone that is having chopping and breaks. I don't even know if I can use the evolve kit until this issue is resolved and for that matter, if the speed was running properly in the first place I may have never even needed the evolve kit. I hope an MT responds to this ASAP. Thanks.

have you tested your output pressure from your air system to make sure your only running 450 into the gun as well as aprox 350 out of the mini reg? if you havent done this you may have the horse ahead of the cart. you could have anywhere from 3 to 10 shims in the lpr depending on what the lpr was reading while testing at the final test point.its rare that the lpr is that high out of the box.

wait i just noticed something in your post you said you removed the volumisers and then the cap behind it yiu didnt remove the lpr piston while u were testing did you?

[Major Morningwood]

Ken, first of all thanks for the rapid response. Sorry for the explanation, I put an "s" after volumizer. I meant I removed the volumizer from the exhaust side and the cap (the one with an allen head fitting covering the LPR side). I didn't remove the LPR entirely. I just removed the piston, the shims are still in this order )()( as they were initially. I have a mini gauge on my ASA and it is indicating 465 into the mini-reg. so the tank does not have a blown reg. I also use it on a shocker and that gun hates any inputs beyond 500 or it blows air out the vent hole on the reg so I know it has never exceeded 500. I bought the 12 pack of shims thinking maybe the shims might be bad and I replaced all of them a few minutes ago. Still without any shims the lowest I can get is 80psi. Now with the new shims I can get to 100psi on only 4 shims. The other shims might have been distorted a bit. This seems more accurate as I have been told the shims equal 5 psi each. The other shims were more like 7 psi each. Help. Sorry for the title about WDP, but I really need to understand why this thing can't get down to 65psi. Especially if WDP claims that is the optimum. Thanks Ken.

One last thing, I swapped the gauge on the angel tool kit for a 300 psi gauge I bought from Grainger since they indicate I should set the evolve kit to an input of 300 psi. The maximum I have set the input pressure to is 300 psi. I don't know about any pressure beyond 300psi out of the mini-reg. My mini-reg has had some wild fluctuations of +-15fps since I bought this marker back in October so I don't know if even the mini-reg is working properly.

You said you removed the piston? You need to have the lpr piston in when you use the gague to check the lpr pressure, also, make sure you check it on the lpr side, not the exaust valve side.

[Vantage_TeS]

For fluctuations you might want to look into cleaning the grease that is packed in there as they don't know how long the gun will sit on the shelf ;)

Circlip pliers to get that little clip out and tap the minireg on a cloth on your desk. Wipe the grease off, oil the one oring and reassemble. You will have much better consistancy.

PBJeff is correct...... the piston needs to be in place or the lpr will leak or should i say that it will vent at a rapid discharge pace thus testing the lpr pressure will be absolutely impossible

[Major Morningwood]

Guys, The piston was in when I measured the pressure with the gauge. Everytime before I measured the pressure I reinstalled the piston. I have never left the piston out and performed the measurement. I tried a second gauge to verify the pressure was as the WDP gauge was indicating and it was accurate. It was showing 120 with all 6 shims installed, 80 with no shims, and 100 with only the new 4 shims.

Vantage, I have already completely removed the min-reg about a month ago due to the wild fluctuations. I completely cleaned everything, the piston, the ball, the spring stack, regreased (lightly) oiled and greased the o-rings and reinstalled. I took the dwell back to the maximum setting and proceeded to shoot several more cases of paint over the last month. It has only gotten about +-3 fps more consistent with approximately 10,000 more rounds through it this month. The total overall shots on this speed since October is probably 35-40,000 with paint, probably 10,000 more if you count all the dri-fires from everyone who wants to test it.

It honestly sounds like you have a faulty LPR, unfortunately.

[Major Morningwood]

I heard about several of the speed 05's coming from the manufacturer with faulty lprs, I just never realized that could have been a problem since it seemed to work, it was just always very loud, kicks like a 12 gauge shotgun, and the consistency has been a nightmare. I am hoping I can get some clues from an MT as to what I might be able to do. What part can actually go bad inside the LPR body? Is it not serviceable, I was just wondering if removing the actual LPR, dissassembling, cleaning, regreasing, and re-installing everything would be the trick. However, if it is not a fix, then what gives. Does WDP not check the pressures of their markers from the factory? It claims in the manual that it should run at best 65, and people here are able to set their LPR's lower than that by removing shims. I cannot even get to the optimum with no shims installed.

[GusTopher]

Try removing it entirely, cleaning it througoughly and lubing it. May be all that it needs.

[Sparco]

The majority of the reg can be serviced, there's only one o-ring in the main body that cannot be swapped out. You can replace the following components:

LPR piston
LPR piston o-ring
Shims
Washers
LPR assembly o-rings
LPR main body pressure seal

Sounds like your problem could be that last part. If you use the ram tool on the rear of the LPR main body and clamp down the front part you can remove the back half of the assembly. There's a small seal in there that could be the problem.
