Removing windshield frame hinge screws

[R.K.]

Anybody have any good ideas on how to remove the windshield frame hinge screws on an FJ40? I have drilled them out of several parts trucks in the past, but I would rather not ruin these like that. They have been in way too long to be able to unscrew them, I've tried with an impact screwdriver. I know I could try to heat them up with torch to help loosen them. Any other ideas?

I'd like to know the solution to this one as well. I have gotton all but (2) out of mine and they took weeks of heat, spray, and an impact driver.

I use this---> http://buy1.snapon.com/catalog/item...1&group_ID=863&store=snapon-store&dir=catalog
fits in any air hammer and works like a charm on removing those stubborn phillips-headed screws............

Kriol, Heat, Kriol ,Heat. Air hammer lots of force. etc I ended up drilling and tapping two of them

I had a hell of a time getting my screws out. I was able to get several out with a propane torch and a custom impact tool I built. For the worst, I welded a bolt to the screw and used an impact socket.

A cold chisel driven into the edge of the screw will turn it.

grant5127 and coolerman have the solution. Its amazing to watch the rusty dust start flowing out as you hammer for a second without turning and then you add a little bit of torque and the bolts just spin loose. If you have one rusty windshiled frame to remove it is worth the time it takes to make up a tool like this.

Why not use a counterclockwise tap? Same as a normal tap with reverse thread.

Just drill a small pilot hole in the head of the bolt and twist in the reverse tap, it's worked on 99% of all my old 40's bolts.

Of course this means you'll be needing new bolts, but it's a good time to swap them out for stainless ones.

A small impact wrench with a light use of air will pull them out most every time, make sure you have a phillips bit for it that fits the screw, good luck, Larry

Ive used the same as this here in New Zealand and i works a treat

I used one of those screwdriver thingys you can whack with a hammer, and it turns a bit as you hit it. Comes with interchangeable bits kinda like a screwdriver. Of course lubricant and heat works as well as an addition.

Because when the tap breaks off you have a bigger problem on your hands. It's impossiable to drill out hardened steel and re-tap the nut.
An old school impact screwdriver worked on mine the kind you whack with a BFH like this one.

I just remembered the Tech column in Toyota Trails last summer suggested using muriatic acid.

I'm thinking of trying it on my rig with the bolts that connect the body to the frame, everything else has failed to remove them.

 

[Coolerman]

Don't waste your time with the acid on those bolts, use a sawzall to just cut them. Faster and safer.

Get the longest fine tooth blade you can find. That way the sawzall stays below the frame a bit while the bent blade does the work.

I used an impact wrench and a hammer only $15 at any autoparts shop.... Buy some extra bits as you will break a few.
There were a few that I had to drill slightly and use a reverse out.

Here is what I did to get mine out YMMV:


- Spray screw liberally with your favorite oil - I use Liquid Wrench - although many say Kroil is better

- Tap the screw/bolt face with a hammer - this shocks the bolt and helps loosen the rust's grip

- Use propane torch or even butane lighter and heat up the screw - this causes the metal to expand and hopefully draw in more of the penetrating oil

- Spray more oil on

- Get a Philips #3 bit (hex bit made to fit into chuck or interchangeable screw driver) use a good brand here - I used a Craftsman bit and had good success - cheap bits will bend/break.

- Tap the Philips bit into the bolt head with the hammer to get a good solid fit

- Use 1/4" wrench and slide it over the shank of the bit - or use a wrench that fits may be less than 1/4"

- Use interchangeable screwdriver handle placed on the bit to put downward pressure on the bit and then use the wrench to turn the bit which in turn will turn the screw

This may sound confusing - I may post a pic to clarify if needed. I have removed all of my hinge screws successfully in this manner.

another thing to mention to this thread is that the reason these things strip also is that they arn't really a phillips head .they are Japanese Industrial Standard (JIS) a good fitting screw driver helps also .
