DMC tech help required - PA (UK)

[Lovetone]

IS anyone knowledgable with DMC's?

We have acquired one, and are going to sell it however its leaking from the back of the bolt where you unscrew the bolt with an allen key.

Im hazarding a guess at it being a sinmple oring problem however we are all Eclipse nuts and have no idea how to fix it. Anyone who can help out would be great - we are at the PA next weekend so if it could be a quick fix onsite that would be even better.

Any help appreciated

cheers

going by my pm5 its a oring problem should be a simple swap and relube

if you have a manual should be able to trouble shoot it from there if not ask fly or put a post on pbreview or matrix owners you will have a reply by the morning normaly

the back two o'rings are number 20. As is said above just replace and relube the o'rings and that should sort you out

i would guess one of the internal bolt orings OR theres not enough pressure running through it , air often leaks outta my pm6 when the tanks nearly empty.

best bet is to check the internal orings and check for damage and replace if neccessary

 

[danrandon]

either the back 2 orings on the rear cap or the rear 2 orings on the bolt.

i can send you a couple of each if you want

Hi

Figures that it would be an oring issue
I think we pretty much have every oring at our site
Just we dont have any dye lube and to be honest no way of definitely trouble shooting which orings are to blame

what lube specifically does the gun require on the bolt parts?

thanks for all help thus far

 

[Game]

dow 33 will do the job very well

 

[danrandon]

slick honey will also do the job, i personally find the dye lube a little to thick and sticky.

 

[Game]

dont some people use matrix muck as they call it ? a mix of several things to make a custom lube?

AIR LEAK BETWEEN THE BODY AND REAR CAP
- Replace the #020 o-ring on the bolt rear cap

AIR LEAK FROM THE BACK HOLE OF THE BOLT
- Take out the bolt, unscrew the back part of the bolt and change the #009 o-ring on the back of the bolt shaft.


all orings are metric sizing
never heard of matrix muck though
