mattybugeye 884 Posted January 28, 2014 Report Share Posted January 28, 2014 (edited) After picking up a tx200 at a bargin price off a fellow member other day I set to work getting it up to scratch on my day off today. Cocking was gritty and harsh after a strip down quickly found the cocking shoe was clean snapped in half.and all internals covered in metal filings/shards (see pics) A trip to aaron wheelers this morning picked up a new shoe and thaught while its in bits will give a good clean polish and re lube . Inside was a sorry state very dirty grease and gritty as hell I cleaned spring took piston from compression chamber and degresed with scotch pad then polished up with lig oil came up really nice. removed the piston delrin rings cleaned and re lubed underneath and refit lubing as I went using abbey lt2 grease on everything then cleaned all the bore of compression chamber it has some light swirling on but nothing too bad (well as far as I'm aware no expert at all) the bottom spring guide has some deep scoring on so will eventually be replaced . I used some fine wet and dry to clean up the top and bottom of spring so smoother twisting on cocking there was 2 washers below the top hat it was chronod at 9.5 when bought so tried adding another 2 washers but later had to remove 1 as wouldn't cock properly with 4 in! Managed to get everything cleaned greased up and back toghether today so had it chronod again now 8.6 !!! Put around 50 pellets through it before taking for chrono was pretty accurate at 25 yd with odd drop in consistancy But cocking nice and smooth now Also cleaned all trigger mech up as was full of metal filings ?? seems really bizar thaught a good clean / re lube extra washer would improve not reduce power has anyone had simular problem or any advice??? Bit stumped!! Think maybe a new spring in order any recommendations of any that worked well in your tx ? Only looking for 11ft lbs really . Few pics of what I done today will follow... Thanks .

mattybugeye 884 Posted January 28, 2014 Author Report Share Posted January 28, 2014 (edited) The groups it was getting after clean up ... There is around 10 pellets in each group as can see was improving but odd few completely out of the groups guessing was dropping in consistancy started in middle then bottom then top groups were much beter Edited January 28, 2014 by mattybugeye Quote Link to post
slave 33 Posted January 28, 2014 Report Share Posted January 28, 2014 (edited) The spring has been replaced with a sqare section spring these are not ideal how much preload did the spring have? as it may be to short best to get a replacment. The metal filings could be from the washers the preload washers air arms use are hardened steel lesser quality washers can be chewed up leaving metal filings. Check the condition of the piston seal put the piston in the comp tube put your finger over the transfer port push down on the piston. Check the condition of the breech seals in the comp tube. Also check the lockup of the comp tube make sure there is no play when the gun is cocked as sometimes the cocking shoes can be under sized. Edited January 28, 2014 by slave 1 Quote Link to post
mattybugeye 884 Posted January 28, 2014 Author Report Share Posted January 28, 2014 (edited) There was 2 thin washers in to start with I added another today about as thick as them two that was in. I forgot to add I checked the piston seal had loads of pressure with finger over end and stopped me from pushing any further at all. The breech seal looked fine too? The shoe seemed a lot more snug than the 1 I removed and carnt feel any play when cocked Edited January 28, 2014 by mattybugeye Quote Link to post
mattybugeye 884 Posted January 28, 2014 Author Report Share Posted January 28, 2014 I've been looking at the welsh willy kits they seem good well review's do think its a titan spring and derlin top hat and spring guide ?? Anyone used this kit and removed the metal top hat and metal guide ? Quote Link to post
barrywhite 282 Posted January 28, 2014 Report Share Posted January 28, 2014 (edited) the spring may be to powerful as well as being square wire that may cause friction .try the gun with no washers or no top hat see what happens .I have had power drop because of to much spring . ...but the spring does look like some coils may have been removed .

mattybugeye 884 Posted January 29, 2014 Author Report Share Posted January 29, 2014 Yea il try that too put a wanted add up for a chrono so can play about and see what results I get Quote Link to post
mattybugeye 884 Posted January 30, 2014 Author Report Share Posted January 30, 2014 Bit of a update I've been and bought a new titan spring today after work and started getting it fit ... Sanded the deep scores from spring guide and removed top hat and pre load washers its still far too long to put back in any ideas how much to trim off or should I just cut maybe 2 coils at a time untill it will cock and cut as needed after a chrono never trimmed a spring before don't know why they not pre set per gun really. Its a titan xs no.9 as that's whay gunsmith reccomended. Cheers Quote Link to post
mattybugeye 884 Posted January 30, 2014 Author Report Share Posted January 30, 2014 As can see way too long Quote Link to post
mattybugeye 884 Posted January 30, 2014 Author Report Share Posted January 30, 2014 Cut couple of coils as had no choice really.. Managed to get it back together not and its hard to cock put 1 shot through it and sounded like a centre fire rifle !!!! Kicks like mule so guessing going to need at least same again taking off will trim up and take for chrono tomorrow before work then bend coil end down to seat nicely bet bloody power up now though lol its stripped down just to be safe as not having it off ticket fac!!!!
