Ok, firstly the 2 phillips head screws which hold the indicator gear housing have rounded heads. I need a way to get them out.
I have tried spraying wd40 to remove rust then used screwdrivers, side cutters, pliers to get them out. Cant get a grip.

Please dont recommend the hammer and chisel method as there is no space to do it.

I got a screw extractor thing, but its useless.

What else can i do?
I have my Ps test in 3 weeks and really need to open the housing up and clean it before my test.

Impact driver, drill them or use an easy out.

How would i use an impact driver when the head is rounded and facing the ground?
Whats easy out?
Also i borrowed my mates drill, does the drillbit need to be bigger than the screw head?

NO! You want a drill bit that's slightly smaller than the screw thread.

could cut a slot in it with a dremal, then use a big flat head....

i looked up easy outs
it is a screw extractor set
im not too sure how to use them
i thought they are meant to be used in your drill and thats what i tried


i tried using a drill bit a bit smaller than the head and it drilled a hole in the head but didnt get rid of the head

wouldnt be able to cut a slot in the screw
i'll try and get a picture up to show what i mean
the screw head is facing down and it has like something covering the sides, so you wont be able to cut a groove in it

i've got tafe now, i'll try and get a picture up by around 7/8

Use an electric impact driver, you stick it in the top of the screw, hold it onto the job nice and tight and then press the "undo" button

For an easy out you drill a hole up the guts of the screw, put the easy out into a tap handle, or, I guess a power drill and then put it into reverse and undo the screw.

you can see where the 2 screws are
too dark to take a picture right now, but i'll try and get one up asap

but how would an impact driver stick inside a rounded screw?
the screw head is so badly rounded that an allen key could fit in it
plus i dont have an impact driver

i'll try that
although i doubt its gonna work

 

[Drew]

if theres anything like a blade pattern then you might have a hope of getting it out with the impact driver, I've recovered some totally fucked up screws with mine. If its beyond even that though its time to use and easy out.

EDIT: heres the impact driver I've got, its excellent for motorbike bits because it is extremely small and light and will do up to 100Nm so it is capable of doing pretty much everything on a bike which isn't a clutch basket center nut or an output sprocket nut.

nah i wouldnt be able to fit something like that on the screw as space around it is limited and it wont fit on the screw's rim
look pretty mad, how much did you get it for?

i'll try the screw extractors again
hopefully they work
or im gonna have to drill the living fuck out of the heads

lol it takes standard impact bits, which are just a 6mm hex, so you can get a bit which is about 50mm long, I've got a good kit by Hitachi which as very good for this sort of thing.

I bought it from a tool place in Sydney off ebay in a kit with an angle driver, a couple of batteries and a torch for something like $300 from memory, the Hitachi bit kit was something like $30 but I had to get that one from the UK.

 

[wins]

are you sure your using the screw extractors properly? because my chain guard had ferked up bolts on it and a screw extactor worked suberbly

 

[Two50RR]

the indicator screws are tiny.........

what kind of pliers are you using?? i dont think you will get enough pressure with long nosed pliers........
but a pair of decent pliers should get it off and if it doesnt come out, the plastics would probably crack off anyway.

ah......way out of my budget for now
but maybe something to look forward to when i finish school

i dont think i used them right
apparently your meant to hammer them into the screw and then use the t handle thing to twist it out
i'll give that a shot today or tomo

and yes two50rr, they are pretty tiny and in the worst position
had to take the fairings and air ducts out to get some space to work
i used long nose pliers not normal ones coz they wouldnt fit
i'll try that as well

 

[aj26]

drill a small hole and use easy out? I got a set thats inside my tap n die set... if u wanna use?

 

[viper33]

i've got easy outs and drill bits, but thanks for the offer
i wont be able to use the easy outs on one of the screws as i started drilling it out of anger
the other one i should be able to

i'll do that today if i get time or tomo
thanks

 

[Drew]

One of the reasons people have trouble with easy outs is because they don't drill a deep enough hole in the screw, so the easy out ends up bottoming out and snapping or reaming the hole.
