Nige,

Nice one I'm off to Lidl to buy a hot melt glue gun

It works a treat

My next article is on trigger mods

"Step 3 Pivot compression tube upwards, drive out pin holding in back block, and slide back block out."

Nige,

I'm having a problem getting the back plastic block off the compression tube. I can't see "the pin" mentioned above. Can you advise where it is ?

Looks to me like the black plastic end block is screwed into the compression tube....but maybe I'm mistaken

Paul.

Thanks for that. think i might try some of that next weekend.

Just had a quick read.
Nige you say it is 10 years old with a plastic cylinder yes??
Mine is 15 years old and has a metal cylinder?
Can you help me out there??

Cheers

Hi folks,
OK, the article was not written by me as I state on the page so I don't know about plastic/metal pieces or whether they changed or not, but the block is held in place by the knock-out pin...if you look HERE there is a blow up diagram which should help you out a bit. My block came out easily.
Best wishes,
Nige
If you can't see the diagram clearly, I can mail it.

like i said i might try it on mine cause it is very underpower.

Thanks for the additional diagram, Nige - my compact cylinder is slightly different to the PR-45 shown. My compact cylinder has no pin through it holding the black plastic block in place. I think my block must be a screw fit in the cylinder (as is the other end which holds the piston rod in place). must just be very tight.

I did however find the cause of my leak - a perished "O" ring on the firing valve.

Worth mentioning that it's a good idea to apply a drop or two of silicon oil into the air intake hole on the cylinder periodically. his will help keep the "O" rings moist in use.

Paul.
