    Record Champion Pistol

    Hi All, I've been given a Record Champion pistol to try and fix for the owner.

    I've managed to strip it and the very strange oval piston seal appears badly damaged; it looks like the consequence of dry firing. I've tested the piston unit in the compression chamber and it doesn't produce any form of seal due to its condition.

    Parts don't appear to be available and there's very little information on how to strip and rebuild the gun as to be honest I found it difficult to get apart.

    I'd be grateful for any help or suggestions, especially knowledge of servicing these.

    Thanks

    BM

    Someone must have come across one of these pistols?

    You may have trouble getting specific information for the Champion as they are quite complicated and also rare, so few will have tackled repairing them. Why not consider its relative, the Record Jumbo, as a possible model, as it too has the oval piston seal, which would have been made out of the same material? Jimmy Dee has provided an excellent stripdown guide for the Jumbo and explains how he dealt with the problem of a crumbling seal https://www.facebook.com/notes/jimmi...34282330002971. He had one machined specially, so you could contact him (he is on this forum, as JimmieDee) for more information. I personally would make my own seal from PTFE sheet and a Stanley knife. It might not be as efficient as an original, but at least you would be able to get the gun working.

    I have stripped one of these. They're not too hard once you understand the mindset of FB. Most people don't realise the the muzzle is a "nut" that needs to be unscrewed. Once that's done I think the rest follows fairly well.

    As for the seal though, you can't get these anymore. A friend tried to make some but the material is too hard really. It needs a bit of flex to make a good seal. Ideally one would try again and make a groove around the perimeter to fit an o-ring. However you also need to seal around the barrel too.

    If I was to try to make another seal, I would attempt to make one from thick leather. It will swell a little with oil and seal the pistol better although the friction could reduce the power a little.

    Other than the piston seal, the other very brittle part is the little plastic pellet probe. If do not follow the cocking procedure, it's going to snap. You might be able to make a replacement using a 3D printer.

    A few people have asked how to service the Champion.... it's about time I wrote a guide!

    All the best,
    Jimmie

    Seized muzzle nut

    Hi Jimmie,
    I have a champion in good nick but running at 1.5 ftlbs.
    Got a new seal ready to install but can’t for the life of me undo the barrel nut.
    Got appropriate circlip pliers, heated it a bit, used penetrant and even given it a little tap but can unsieze it.

    Is it possible to strip it without removing the barrel?
    I’ve removed the pellet insertor but cannot get the top casing off, there’s something stopping it lifting off completely and I don’t want to force it.

    Cheers,

    Matt.

    Unfortunately you need to remove the barrel nut. There is nothing else holding the muzzle nut in place. You probably just need to "crack" it loose. Stick the gun in a vice so you then have both hands on the circlip pliers. Alternatively, you could make a tool from a hex socket. Grind / cut it to make some (maybe two) pins to fit the muzzle nut. Then you can fit a larger bar for more leverage. Good luck!
