I went to remove the resevoir cap the other night to top up with fluid but as i tried to unscrew it i dont know if the screw had rotten or not but the screwdriver just spun and rounded off the phillips slots does anyone know the best way to get it out so i can replace it?
Personally, I'd try to get a tiny drill bit and drill out the screw, or use one of those reverse-threaded bits to pull the rest of the broken screw out and replace it.
I'm afraid that's going to happen to me when I get my old bike back....
People torque the crap out of those damn things. They don't need a lot of it.
We have an impact screwdriver for when we have a bike for which that's been done. We also have a supply of replacement bolts.
If yours is beyond any Philips driver, I'd use a small bolt extracter; have a new bolt on hand.
Cut a slot in the screw head with a Dremel and turn it out.
Failing that:
1) Drill the head off the screw
2) Secure heavy Vise Grips to remainder of the screw stub
3) Turn out screw
Failing #3, drill out screw with suitable drill .01" smaller than minor diameter of screw thread. Twirl out remaining thread.
I had the same thing happen to one of my bikes. I used a dremel to slot the screw (and part of the cover, unfortunately) then got it out with a flat head screwdriver. I then got a new cover and set of screws and everything's fine now...
AMEN to there being no need to tighten a screw like the reservoir cover so tight. :2guns: I hate it when people senselessly over-tighten screws and cause problems like this, but I'd like to add a word of advice about Phillips head screws. If you first clean any rust or debris that may be in the screw head, be careful to find the CORRECT size Phillips screwdriver or screwdriver bit before attempting to remove a screw, and use downward pressure as you unscrew it, you can greatly reduce the odds of ruining the screw head.

Yet another excuse to buy a nice set of JIS screwdrivers...

eerrrmm.....so am I, and I can spare the cost of a stamp. The offer is there :thumb:
After reading this I tried mine to see if they were stuck- they started to move OK, but then got tight. When I bought the bike it had been dropped and there were scrape marks on the cover, turns out as it hit the road the cover moved and bent the screws. Managed to get them out, but didn't have spares so I screwed each into a nut and bent them fairly straight with a pair of pliers. Will do till I get new ones, but they are certainly very soft, must be warm peanut butter! :dunno_black:
How much for postage to Australia sledge? :laugh:

I may actually order these. I completely forgot that there's a difference in the screws. Stripped PLENTY of em at my last job modifying Panasonic laptops....they too, were made of a butter-like substance and the paint would chip if you looked at it the wrong way.
hey guys thanks for the assisstance yesterday but thankfully i managed to get the screws out by sheer luck. took the term of impact driver to the n'nth degree.
put a screwdriver in hit it with a hammer and tried to turn it and heypresto it worked :D
