Question On Removal Of Old(30+Years) Wiper Arms (C2 Corvette)

[Larry E.]

Here we go again on wiper arms. Having a heck of a time removing the old incorrect wiper arms on
my 66 Corvette. Have N.O.S. Trico arms to go on when old ones are removed. Have tried to remove
them with the Snap-On removal tool(A-192) but with no luck. Spines must have corrosion on them. I saw an
idea on You-Tube with the guy drilling a hole through the top of the wiper arm "cap"; then putting
penetrating oil on the spines from the top. You would think this should help. He tried the tool like
I have but still would not come off. Next step was to drill a bigger hole and uses the "puller type" tool
shown below. He put a bolt between the puller and spline and the arm came right off. Has anybody done
this or have other ideas??? We all know you have "TO BE SO CAREFUL NOT TO CAUSE ANY DAMAGE".
Thanks in advance>>Larry

My only advice is to put a moving blanket over the windshield, the cowl vents and all around the wiper arm before going "medieval" on it. If that puller device pictured does not work then you have some serious rust issues going on.

Try PB Blaster penetration fluid and let it sit for a couple of days, Maybe a little bit of heat.

Mike: Thanks for the response; will certainly try this idea but I'm not sure on what the outcome will be. Have tried to put some
penetrating fluid on before but all it does is "run down". Don't believe any is going where we want it to go. BTW>Will use a little
heat from the heat gun but should this be applied when the penetrating oil is applied or just before we try to pull it off? Or at
both times?? Thanks Again>Larry

I'll second the vote for Freeze Off.

I have tried Freeze off with no luck. Hopefully you will.
I would soak the arms with PB Blaster for several days, and make sure you protect your paint. I don't know if PB Blaster will harm the paint but just be cautious.

Larry,

I like the idea of drilling a hole in the arm then soaking it with PB Blaster, be careful using heat but I would try it then apply the PB Blaster after it gets hot.

My Freeze-Off suggestions was simply because I, personally, would be more comfortable with that, than wielding a propane or MAP torch around the painted cowl area of my car. I understand its almost never a problem - almost.

If you don't care about the arm, take a Dremel with a cutting wheel and slice up the sides . Pry apart with a screwdriver and it should pop off.

Larry, I don’t if you know about the wiper arms having a spring locking device under the wiper arm pivots which cannot be seen, there is a tool that Lisle Tool makes the tool to remove these wipers(65750). Just a thought in case that maybe the problem.

[Frank D.]

Re: Question On Removal Of Old(30+Years) Wiper Arms (C2 Corvette)

He tried the tool -- as mentioned in his first post.
I'm actually liking Harry's idea; just use a Dremel cutoff wheel down a couple of sides of that arm and that it'll come right off (maybe use the tool, but maybe not).

Re: Question On Removal Of Old(30+Years) Wiper Arms (C2 Corvette)

Thanks to all for the ideas. As far as those tools go like the Lisle65750;snap-on A192;the paragon and LIC they are all
basically the same. They will work when it is an "easy off" project. They just do not have the angle or torque for the
hard pulls. Will try the freeze-off 1st if no work will drill a hole in the cap and put freeze-off or PB Blaster from the top.
Will not use open flame around that part of car but may use an electric heat gun. Stay-Tuned; will report back.>Larry
P.S. Will use the Dremel idea at the last resort.

Dremel and cautious sounds like the best and fastest idea to me.
