zini 1,939 Posted June 17, 2013 Report Share Posted June 17, 2013 Try and Google a how to strip a HW97KT mate. I watched it done and its really easy. If you can get the spring out you could send it through the post to one of the members on here to get a coil removed or remove one yourself. I know DavyT63 may be able to help you if you ask him. He as done 3 of my rifles now by removing a coil. To get the rifle shooting at its best for hunting and HFT together you would be best getting it set around 10 FPE to 10.5 max mate.

I had a couple of hairy moments first time I did it but I was just nervous didn't want to nacker my expensive rifle.. but really you wont go wrong if your carefull and follow this vid. to get the spring out you don't actually need to remove the cocking lever or piston. remove the stock screws and trigger guard screws, remove trigger guard and separate stock from action, remove large bolt next to trigger unit with 13mm spanner, remove trigger unit by punching out 2 pins, (make sure you don't lose the safety catch as it may fly out) unscrew the end block off the rifle (might need a big spanner in a rag and a hammer to get it loose enough to unscrew by hand) when its nearly out make sure to keep a good grip as it may pop out with a bit of force, as its under tension from the spring. you won't need a spring compressor. after this the spring will just slide in and out of the piston hope this helps mate SKoT Edited June 17, 2013 by Skot Ruthless Teale 1 Quote Link to post
valboskie 39 Posted June 17, 2013 Author Report Share Posted June 17, 2013 Thanks for the reply lads. I have a totally standard hw97k I might strip that first for practice before I try my pride and joy. Once I get the spring out how do I cut it down .where do I cut .I have read about you must finish of the spring ends and polish them. What does this mean in what way do you finish them. Or do you heat the spring and crush the coil .do I have to relube the spring. Im just a bit worried I ruin tonys work. Quote Link to post

valboskie 39 Posted June 17, 2013 Author Report Share Posted June 17, 2013 Thanks for the offer mate but Aberdeen is just to far. Im in Greenock about 30 miles from Glasgow. If I cant sort it out im on in july for 2 weeks I might take a drive up . Cheers David Quote Link to post
thursodog 353 Posted June 17, 2013 Report Share Posted June 17, 2013 No worries.it really is a piece of cake. Tuning it though is more involved and can be a disaster. Davies vid is all you need to diy it. Good luck. Quote Link to post
