Had to replace the mainspring.....

[techmike]

Don't know if this is "normal" for the Colt/Umarex or not. (14 months and about 3.5K to 4.5K rounds) But the mainspring deformed and wore badly. Started to get some strange functional issues. Paid $12 for new one including shipping. I have never seen a spring deform like this before. :confused:

Well, Colt says I had the spring adjusted too tight. (On the original spring). The new spring, (which is a heavier spring per Colt), should be adjusted as follows: With the adjustment screw flush with the surrounding metal, turn it in 4 complete revolutions clockwise.

So, you were shooting really hot ammo? And the factory spring can't handle the hottest ammo?

Uh, no. Federal bulk pack mostly. Nothing super hot. The spring is capable of much more than 4 revolutions, and they say I had it too tight.

You tightened the main spring just enough to operate properly with Federal bulk and Umarex claims you over tightened it? They should have covered the cost.

Yeah. But the rifle is out of warranty.....  :confused:TM

I've had my spring cranked in all the way for a year, several thousand rounds down the tube. I looked at the spring closely and don't appear to be developing any issues. Thanks for the heads up.... :beer:

Yeah, I noticed in your Cleaning Video, your spring looked a little "kinky"!
