Aa S410 Home Service - Stuck!

[silentshot1 206]

In an attempt to save some money, i bought a AA service kit and instructions to give my AA S410 TDR a long overdue bit of TLC . To be honest all seems pretty good.

 

That said, I started last night and came a cropper at almost the first hurdle, by one of the Alan screws on the top plate being worn badly and not replaced in the last tune by AA.

 

Does anyone know how I could get this screw out, with a basic tool kit? The 2.5mm Alan key not making contact with the worn sides (not a metaphor for my sex life) and the next up, is to big..

 

I thought about super gluing the Alan key to the screw, which seemed a tad OTT and have tried widening it with tin foil, pliering it etc. to no avail.

 

Any ideas gratefully received! Drilling seems an easy way but don't trust myself not to fcuk it up royally!!

Ive had this before on cars, and my normal trick is to get the size bigger allen key, and file/grind it down to be a perfect fit in the allen bolt. Sometimes you can gently tap it in with a hammer once its nearly the right size to get a tight fit.

 

Ive done this on brake caliper bolts in the past which are a lot bigger!

 

Apart from that, ive serviced my s410 no end of times and never had any problems. Just take your time and make sure all the seals are in the correct place - espectially the action->barrel small seal - that can fall out when you reassemble if your not careful.

try an imperial size key, most of the time they are between the metric sizes, if its very close as said earlier by someone else file it down a bit then tap it in gently home, just make sure you replace it afterwards, may be an idea to replace them (the screws) all while your at it

Try a torx key, its what i usually do when i find a stuck allen bolt

I was going to say try metric or imperial, which ever is the oppersite to what you're actually using!! Patience is a virtue.......

probably ok on small screws used on airguns (as long as worn, not overtightened) problem is torx bits don`t have much meat on them on the points so they are b"£$ards for snapping when you do this (thank god for snap on`s lifetime guarantee),file another key down to fit

Thanks all for replies and idea's. Tried the metric to imperial but neither worked, going to try the filing route and buying a hex key over the weekend! Not to worried about screw as have replacement.

before attempting this below,make sure Reservoir is empty

 

if you are going to use the hex key,make sue you use a 3.mm or 3.5mm punch the bit it in with a hammer,not aggressively just tap it in till it stops.then add the wrench or driver and turn slowly you may even have to give it a quick turn clockwise,then anti clockwise till it comes out.

 

if this fails you will need to get some easy outs

if you get into easy out territory do NOT snap it off in there cus they are hard b##tards.

Did you get it out in the end?

Sorry had a go yesterday and, yes, thank you! A torq key and gentle encouragement with a hammer and as simple as that!

 

Will be continuing this evening/tomorrow evening... Thanks again to all for help!
