i picked up a Radar MARK 2000 at a tag sale for 25$. it uses a back bottle ASA. i always envy the people who play with pumps rather than a marker that shoots 30+bps so i said what the hell. heres what it looks like whole.
and the internals
i broke paint in it and took it apart. i dont know what happend but its not workin now. i can pump it back and the 2 bolts some together and slide em foward, pull the trigger and it shoots. the problem is the bolt dosent go back far enaugh so a ball cant drop down into the chamber. i think my problem is part # 4. im not entirely sure where it goes. i take it out and the bolt can clear the chamber but the striker dosent hitch to the bolt, so no fireing. if someone can give me a users manual it would be much appreceited. or tell me in what order the parts go in. anything would help.
heres some more pics with the pump all the way back. you can kinda see the bolt there.
P.S. the ball dosent flow smoothly in the chamber also. i have to force it thru. its like it dosent fit.
this is the resopnse i got from pb nation.

That would also explain why it won't come back far enough for the bolt to clear the feedneck as well.
I've got 4 old Nelson based pumps here and none of them have that #4 collar. Could it be meant as a spacer for the pump plate to bolt screws?
So try assembling it again but this time without the #4 collar. I'll bet a previous owner thought he was being smart by adding it. Or he may have put it in there because the spring is getting weak. You may need a new one. Cocker hammer springs are supposed to work.
As an interim you could try to stretch this one a little but that's living on borrowed time usually. If you do try it measure and stretch a bit and measure again. Keep stretching further in SMALL steps with remeasuring after each try until it's about 1/4 inch longer. Don't go more than that or it'll really mess up the spring of the metal.
For highest velocity the bolt and hammer should be wiped down with a thin oil and most of that wiped back off. The thinnest of films will give you the best velocity. I found that out the hard way with one of mine.
That oldie looks like it's in great shape. You got a good'un there you did. |
i dont have any c02 right now so ill test that theroy when i get some this weekend. anyinsight at all or a point in the right direction would be greatly appreceited.
thanks alot in advance!
