Fabhui Posted July 27, 2016 Report Share Posted July 27, 2016 Got the TX200 out today for the first time in several months and noticed it was shooting low on power. Over a year ago I fitted a Welsh Willy spring tuning kit to it with great success. Anyway, I disassembled it to see what might be causing the problem to find the spring is jammed in the piston and just doesn't seem to want to budge. The end of the spring that's jammed has a delrin top hat fitted and between that and the bottom of the piston is a delrin piston spacer/washer. Anyone have any ideas on how the spring can be freed from the piston? Cheers Quote Link to comment Share on other sites More sharing options...
hyflier Posted July 27, 2016 Report Share Posted July 27, 2016 I'm afraid fella, you're going to have to use some force with a twisting action to remove it. It's a TX200, the only thing you're going to hurt is the spring and it sounds like you're going to need a new one anyway Quote Link to comment Share on other sites More sharing options...
8outof10 Posted July 28, 2016 Report Share Posted July 28, 2016 Mite be worth taking the piston seal off, stand the piston, spring side up, in a bowl of boiling water for a few mins then try pulling the spring whilst holding the piston in a towel (dont wanna burn ur hands on a now red hot piston) Quote Link to comment Share on other sites More sharing options...

Fabhui Posted July 28, 2016 Author Report Share Posted July 28, 2016 So what next ? different spring an kit,but which way to go? Well it's got a Welsh Willy kit fitted, including a new piston seal which I fitted only last year. The thing is I fitted it and never used it as I bought a PCP and have been using that. The thing is I took the TX200 out for a play and thought it was running low. Put it through the chronograph and it was barely touching 4.0 ft/lb!! I put the original spring, top hat, guide etc back in and it's only reaching a high of 6.8 ft/lb. Now I'm left scratching my head thinking what to investigate next on it. Could it be the breach seals, compression tube seal?? Any ideas or help appreciated. Quote Link to comment Share on other sites More sharing options...
timmytree Posted July 28, 2016 Report Share Posted July 28, 2016 Standard spring with Tinbum guide and tophat, new breech seals(2!) That should cure everything. The comp tube seal very rarely fails. Quote Link to comment Share on other sites More sharing options...

The comp tube seal very rarely fails. Cheers! I'll invest in a couple of breech seals first of all then. Quote Link to comment Share on other sites More sharing options...
