manthing Posted April 20, 2020 Report Share Posted April 20, 2020 Hi all. Noticed my ultra se is not as smooth as it used to be when pushing the bolt forward to load the gun. It has had some occasional sprays with some silicone lube but that's all. Any one any ideas before I get the big hammer out? 🤔. Quote Link to comment Share on other sites More sharing options...

Mice! Posted April 20, 2020 Report Share Posted April 20, 2020 Xtx YouTube videos are really good, I watched them then bottled it and sent my R10 off to get fixed. Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted April 20, 2020 Report Share Posted April 20, 2020 Silicone Oil is not a lubricant recommended for metal to metal in Airgun applications - try taking your bolt out and clean it thoroughly - then either a tiny bit of mineral Oil, a fine smear of lithium grease or rub a soft pencil over the bearing surfaces.

manthing Posted April 20, 2020 Author Report Share Posted April 20, 2020 Cheers @Mice!. @bruno22rf it was more to lube the o rings. Quote Link to comment Share on other sites More sharing options...

And that is what is most probably causing your problem.... The pellet probe o ring is more than likely breaking up 😉 Quote Link to comment Share on other sites More sharing options...
manthing Posted April 20, 2020 Author Report Share Posted April 20, 2020 The lube used for the o rings on the fill probe is silicone bases according to the label that was on the pack. Go figure. So, how do I get at it and a good place to get a set from please. Quote Link to comment Share on other sites More sharing options...

Go figure. So, how do I get at it and a good place to get a set from please. XTX Air on YouTube does guides for all things airgun,,,, mainly BSA's. Take a look on there,,,, very good help and advice on just this problem 👍 Just search xtx air bsa ultra pellet probe,,,, numerous options appear, the one you need is near the top. I must add, he makes it look extremely fiddly, and it is. There are many other ways to change the o ring, I think most people make up their own method. I use a bent-up hair pin which works quite well 😊 Edited April 20, 2020 by JKD Extra information Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted April 20, 2020 Report Share Posted April 20, 2020 As above .silicone is bad for metal to metal contact .it does the opposite of what you want . So whats probbly happened is the bolt coating (chrome ) will be flaking off inside the breach .causing extra wear . Best get it stripped down soon as poss.and resist the temptation just now of cycling that bolt unless you have too . As it can be ok 1 second and on the next try .totally jammed up I always lube with abbey sm 50 for orings and every where on a pcp with no issues so far .

JKD Posted April 20, 2020 Report Share Posted April 20, 2020 ^^^^ This also could be the problem,,,, good of stu to point it out 😉 From memory, weren't some probes susceptible to this flaking issue ? Also to add,,,, the Abbey SM50 lube must be used in tiny amounts ! Quote Link to comment Share on other sites More sharing options...
Shufti Posted April 20, 2020 Report Share Posted April 20, 2020 Is there any sideways play in bolt? If so replace the plastic! bearing. XTX shows how...straight forward. Quote Link to comment Share on other sites More sharing options...
Longbower Posted April 20, 2020 Report Share Posted April 20, 2020 It does sound like the dreaded flaking bolt! Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted April 20, 2020 Report Share Posted April 20, 2020 It can be the probe banjo band coming loose this starts to make the gun feel rough. Then it slips completely and jams the bolt . Quote Link to comment Share on other sites More sharing options...
manthing Posted April 20, 2020 Author Report Share Posted April 20, 2020 Thanks for the info. Did have a look at xtx but didn't see much for ultra. Need to look again. So anywhere open to order a seal set from chaps? And if the probe is flaking does it need replacing, a rechrome or can it be stripped, polished and kept lubed? Do I need to empty the cylinder?

The ultra .scorpion and r10 all work the same in the bolt area .. I think xtx used to make a stainless steel version of the probe which solbed the issue It may be possible to scrape it off and it still work ?? No you dont need to empty the cylinder .but i would as you dont want to accidentaly loosen a bolt you shouldnt on a fully pressured tube .

manthing Posted April 21, 2020 Author Report Share Posted April 21, 2020 Cheers peeps. Looks like I might just park it for a few weeks if I can't get the bits, but then when I get back to working I'll probably not have the time to sort it... All or nowt sometimes..

Ultrastu Posted April 21, 2020 Report Share Posted April 21, 2020 Thats probably a good idea Not a lot of point in stripping a gun down .and not being able to put it back together again straightaway. Its too easy to forget how it goes or loose something . Quote Link to comment Share on other sites More sharing options...

Perhaps take the spare time to internet search for any items you might need 😉 As for the seals, I'd buy a set - and extras - because more than likely you'll be needing those. Good luck and stay safe 👍 Quote Link to comment Share on other sites More sharing options...

I couldn't then get the bolt open and ended up sending it for a service. Quote Link to comment Share on other sites More sharing options...
