Guys, My fzr250 needs the front brake bled, but one of the screws on the brake fluid reservoir container doesnt have any thread left on the head! What options are left to get the screw out?? Additionally, the allen screws in the cap that holds the oil filter are EXTREMELY stubborn, and won't budge an inch, after trying everything. Even tried spraying WD40 and leaving it overnight.....nothing. Any help would be gratly appreciated, mostly for the first issue. Cheers.
for the oil filter cover on the bottom of the engine, try an impact driver with the correct size allen head bit in it. They will either come out or break. If the screws break, they should come out once the cover is off, as most of the binding force is the friction of the screw head on the cover. P.S. The allen head screws are high tensile and can take a lot of force.
FASTENERS REF STUCK FASTENERS, YOU HAVE SEVERAL OPTIONS AVAILABLE, TRY FIRST TO USE A SMALL CHISEL AND HAMMER TO GET THE SCREW MOVING,OR CENTRE PUNCH THE SCREW HEAD AND USE A SMALL DRILL BIT TO REMOVE THE SCREW HEAD, THEN WITH THE CAP REMOVED USE PLIERS TO REMOVE REST OF SCREW.FOR THE OIL FILTER CAP TRY TAPPING THE HEAD OF THE SCREW WITH A METAL BAR THIS SHOULD FREE THE THREAD,AND USE SOME EXTRA LEVERAGE ON USING THE ALLEN KEY, IDEALLY USE AN IMPACT DRIVER TOOL.
THanks guys. Been researching a bit, and it seems a impact driver is the way to go. Getting leverage on the allen bolts of an oil filter is impossible without a lift. I'm just a bit weary of using a screw extractor.
HELP! Got a problem. Tried the impact driver, which did nothing but strip the head even more, to a point now where there is a round hole in the head of the screw. I'm a bit scared of trying the power drill method as it might damage the screw entirely, and make any extraction impossible. Can i leave the screw in and hope my mechanic can remove it on next service?
Re: HELP! If you only want to fill the master cylinder, you could try pumping fluid in from the bleed nozzle on the calipers. However, provided the screw is not corroded in to the master cylinder reservoir, once the head is off and lid removed, the screw should be undo-able with a pair of pliers. If it does not come out at that point you will be looking for a new/second hand master cylinder.
i rounded the screw head on the front brake reservoir.... so I got out the angle grinder and made a 'custom' flat head slot. Although, I did grind a bit at the cap but nothing to worry about (ie through it! <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: --> ) Then I just got out the biggest flat head screwdriver I had and undid it, works well now <!-- s:rofl: --><img src="{SMILIES_PATH}/icon_razz.gif" alt=":rofl:" title="Rofl" /><!-- s:rofl: -->
That was pretty clever BIZZ. There are 1mm thick cutting blades available for 100mm grinders that are used for cutting thin sheet metal (like roofing iron). They would make a fine slot. By the way your up to 200 posts and this is my 500th. I think I spend too much time on the PC, although thats only about one post a day average.
Update In Bizz style, i simply used a hammer and small chisel to make the screw head into a flathead. It took a little while, but worked perfectly. Front brake is great now. Does anyone know where i could find a replacement screw?? Cheers.
Dremmels are good for this purpose, too <!-- s --><img src="{SMILIES_PATH}/icon_smile.gif" alt="" title="Smile" /><!-- s -->
