bruno22rf Posted February 14, 2018 Report Share Posted February 14, 2018 Fairly easy job to do yourself - few simple tools and simply replacing the Spring and Washer should restore her to her former glory. I would suggest that you check the power afterwards just to be on the safe side. Quote Link to comment Share on other sites More sharing options...
rovercoupe Posted February 14, 2018 Report Share Posted February 14, 2018 Preload can be a bit strong on a new spring but not impossible to get back together, everything else is easy to do Quote Link to comment Share on other sites More sharing options...
lozrob Posted February 14, 2018 Author Report Share Posted February 14, 2018 thanks for the replys. the gun has been underpowered for ages , i have since fitted new ox spring , top hat and washers , new piston seal , barrel seal , polished the piston . i was expecting it to be over 12 foot pound but it is still not as powerful as a friends standard out of the box HW97K. Thanks. i matched the seriel numbers with the right size piston etc. i am taking it to a shop in letchworth tomorrow , to get it looked at.

ditchman Posted February 14, 2018 Report Share Posted February 14, 2018 if that is underpowered with all that fitted new ...then something is very wrong..........the hw 77 i have is just on the limit...and will be over the limit if i use a lighter pellet...the internals havnt been touched for many years....and it is deadly accurate...proberly the most accurate spring gun i have ever laid my hands on.. something aint right with yours......... check with your smith about the ox spring your fitted they are a tad vicous and may do more harm than good.........

washerboy Posted February 14, 2018 Report Share Posted February 14, 2018 (edited) Ox springs are truly awful, bin it and fit a standard one Edited February 14, 2018 by washerboy Quote Link to comment Share on other sites More sharing options...
rovercoupe Posted February 14, 2018 Report Share Posted February 14, 2018 My money would be on the spring guide, it needs to be free floating or it saps power right off. and those springs are awful. Quote Link to comment Share on other sites More sharing options...
