as some of you may have read in my other thread about the clutch screws im having a little trouble lately getting some screws out. well i gave up on those for now cause nothing would work and i dont have the proper tools to drill them out and all that.

last week i got a ct70h motor from 50whip and today i was gonna take it all apart and check everything out and low and behold every case screw is a phillips head. NO!!!!!!! im not sure if all old motors are like that but o man do i hate phillips screws that havent moved in 30+ years.

every single screw i tried to get out stripped! im using the correct size bit in an impact screw driver and they wont budge, i even applied a bit of heat to them and no go.

do you guys have any suggestions other than drilling them out? i only have a basic tool set here at my apartment and i only have access to a huge tool set a few times a month when i go to my parents.

if i cant figure anything out im just gonna take these parts with me next time i visit and either cut slots in all the heads or easy out them. i cant think of any other way and these things are starting to get me really pissed!!!

and then on top if it today i hit my hand as hard as i could when i misssed the impact driver! heres some pics:





pics dont look as bad as it is lol and i know its a cute ring you dont have to say it

ive been trying an impact driver but i suspect mine isnt working right so i need to find/buy another one.



whats the craftsman tool? is it like an easy out or something totally different? ill probably soon invest in a set of easy outs and some kind or wall plug electric drill. thers a harbor freight tools down the road from me so i can buy toold really cheap, they are good for 1 or 2 uses lol

The easiest way to prevent that is to hold the impact driver with both hands, have a friend ready with a hammer, and, when you nod your head, he can hit it...




Seriously, try using some PB Blaster on the screws, allowing it to soak down onto the threads overnight, and give the impact driver another shot. You might want to try to "tighten" the screw a hair first, to break it loose, and then try backing it out. Sometimes, a good smack on the impact driver to tighten it will "shock" it, and loosen it.

A quality impact set is crucial. I had a junk one and it worked ok, I bought a nice set and haven't had any problems since. I've taken a couple old z engines apart as well.

If you jack the phillips head you can dremel a slot in the head and use the flat head in the impact set.

The more steady the engine is when doing this the better. Force will go to the screw not moving the engine or ummmmmm.. your hands.

I second PB Blaster but it stinks, I use it outdoors like spray paint. Soak well, tap screw to get it to penetrate. How are you heating, careful as the PB Blaster will ignite. Heat the threaded part not the bolt/screw as you want it to expand and the bolt to stay relatively cold.

The Craftsman screw extractors look like nut driver/sockets, with cuts reverse grips inside that grab the screw head and work very well if you have a head to grab.



Good Luck

Silly thought, if you take the bit out and put the business end on the bench while slowly pushing down hard by hand, which way does it want to turn?



You might be actually trying to tighten them if you did not check that.

Is it compressing when you push? Try holding the top while spinning the bottom each direction and push again. Mine was a little funky to figure out.

Some of these impact drivers do have a nasty habit of reversing themselves right in the middle of a project. It's a pretty violent tool by nature and it's not a bad idea to check the direction after each strike. I like to make a small mark on the screw and case with a sharpie and with this I can tell weather the screw is moving clockwise or ct-clockwise with each strike.

Mine, you apply pressure in the direction you want it to turn. On older fasteners, check and see if the holes are blind. If not, then you can put a little oil in from the back of the hole and let soak. Using heat helps, sometimes, you can use several heat cycles. The aluminum heats and expands faster than steel, seems like this helps the oil penetrate better. For stripped phillips head screws, you can use a punch to flatten the torn-up screw head. Then take your phillips (from your impact driver) set it back in and hammer it. If the screw was not damaged too bad, this will give the phillips a tight fit again. If that doesn't work, then see the post above about cutting a slot to use a flat-head.



Hope that helps!

it pushes down and i can choose which direction i want but when i push it down it doesnt turn, it just goes up and down. so i think its broken. im gonna try to take it apart and fix it lol if i cant ill try to purchase or borrow another one.

my friend has a set of extractors like what you described. ive used them before and they worked good
