A Strange/stupid Problem Regarding My Dustcaps...

[TonyAYGO]

When I bought my aygo I bought a few bits for it off eBay and came across some cheap aluminium dustcaps. On they went, and now, I cant get them off. I only tightened them by hand. Anyone got any suggestions?

Ive tried WD40 and pliers and that doesnt seem to work lol

Bad combination brass and aluminium, they like weld together had to cut mine off.

Get this all the time... new valves required I'm afraid, get yourself along to your local tyre shop.

Expensive dustcaps.

Nex time get stainless steel ones rather than those lightweight alloy ones.

Apparently if you put vaseline on them when you add them it will stop them welding together. But mine did, garage had to rip them off, such a waste of £1.50

I had the same problem on my mountain bike and used copper grease to sort it. I just kept the regular plastic dust caps from then on, because I was paranoid about wheel balance. And it's one less thing to steal from the car. (I had my exhaust trim stolen recently)

Might just work warming them with a hot air gun but be careful! Try your spare wheel if that has the ali. caps first - it it has been under cover the cap might come off easily but only do one at a time in case the valve braking and lets the air out!

It is a very common problem with ali. valve caps - safer to stick to plastic or take chance and use some grease in future.

Only way I got around this was to losen the valve caps and retighten by hand on weekly basis, did force me to regularly check my tyre pressures though so did have a positive turn to it :)

I use RS components Silicon Grease, had no problems, my biggest problem was road salt over the winter.
