Flywheel screen screw removal?

[ebinmaine 67,483]

 

1975 K341. 

This engine lived outside In a tractor that was sometimes covered with a tarp, sometimes not.

Every bolt or screw that we've undone has been very tight.

 

We sprayed the screws with good penetrating oil yesterday. Letting them soak.

 

 

I have a small hand torch that I tried. Propane will make the screen around the screw glow dull red but didn't seem to help break the screw loose.

 

What gas for heat? Other tricks?

 

 

Thanks in advance....

I have used a hand impact driver you hit with a hammer to remove small machine screws.

I have had good results using the hand impact tightening the rusted screw a bit first then going counterclockwise. The tightening seems to shock them loose and shouldn't mess up the heads.

I have welded hex nuts to some of these philips head screws to get them loose.   Some I have had to drill out.

@ebinmaine  part of my lubrication  addiction  is give areas a drink , like long standing  / forgotten  nuts / bolts / screws , found the combo of oil and vibration , makes for good results .  anything usually moves , pete

If you want more heat out of your propane torch, use MAP gas instead of propane. Available off the shelf at many hardware stores, here is one source.

 

https://www.walmart.com/ip/WORTHINGTON-CYLINDER-332585-14-1-oz-Pre-Filled-MAP-Pro-Gas-Torch-Style-Cylinder/39944161?wl13=1771&selectedSellerId=0

 

MAP-Pro gas burns at a temperature of 3,730 degrees Fahrenheit, while propane burns at 3,600 F. Because it heats copper faster and to a higher temperature, MAP-Pro gas is a superior alternative to propane for soldering. If you opt to use it, the manufacturer recommends using a specially designed torch. Adding oxygen to the flame raises the temperature to 5,200 F, which is suitable for cutting and welding steel when precision is not required.

 

Hand impact driver works wonders as well.

I've taken my cut off wheel & cut a straight slot in them before & used my BIG screwdriver to get them out.

That was when I was out of acetyline for my torches.

If you have torches heat one at a time till glowing red, quench it with cold water & it will come right out.

EB if you don’t have a hand impact driver, get you a good fitting hex handled screwdriver like a craftsman.  I think their handles are 1-1/16” hex… give or take.  Get you that wrench on the driver, get some leverage on the wrench and start tapping the driver with a hammer.  It’ll do almost the same.  When I can’t find my impact driver, I do that.

Also, if you have a soldiering iron, you could heat the screw for a while without melting the screen.  I also like to chase heat with some candle wax or paraffin wax.  The heat draws in the wax and the wax lubes the threads.  That trick works on the most rusted, salted snowplow truck fasteners there are.

Old Taryl trick right there…

I like that trick so much I already tried it.

😂

 

Suckers aren't even thinking about budging with that one.

That trick is twice as old as Taryl.

Before I had a hand Impact I used a modified  Pullstart method.  I clamped a longer screw bit for a drill in my vice grip.  Gave the bit a good healthy blow with a hammer, the tied to turn, repeat.  

I bought a Harbor Fright hnd Impact and the large phillips bit lasted about 4 engines.  Now I need to find a replacement bit to fit it.  Buy a better brand than HF

I vote for the hand impact driver. Bought one in 1974 to take side covers off the dirt bike engines, always worked when a screwdriver would not.

@ebinmaine... here is a good thread... the last suggestion is an excellent last resort.

Using Philips on those screws has always annoyed me, welded nuts to a good many of them over the years, impact svrewdriver or a 1/4' electric impact with the proper sized bit, push in hard and feed it trigger slowly, making sure it doesn't cam out

That's my go-to tool for a lot of things. Didn't work either.

 

This is another one of those multiple situations where it would be handy to have a nice easily set up wire feed welder sitting around.

A must have tool.  IMO

Ive got a 120/240v Tooliom 3 in 1, its cheap, can run flux core or gas mig, does arc welding and is Tig capable if you get the lift tig torch.  After about 5 minutes of setup i was burning, its pretty simple to operate..ive run about 10lbs flux core through it this year with the only issues being my own...but its got loads of power.

As the song in "The Gambler" goes - "if you're gonna play the game boy, ya gotta learn to play it right".

A wire feed welder is very easy to master the skill needed to use it well.

And even if you're not good at it...you learn fast.  Most valuable thing to have is a good helmet though...
