bolt/screw removal … hard ones on J&E oldies

[crosbyman]

I do not have an impact driver tool (hammer type nor pneumatic impact tool ) but recently had to remove hard to unscrew nuts & bolts (hex heads or slotted)

I tried my 18V impact "screwdriver" with the appropriate driver or rachet socket size ex: 7/16 or 1/2 using the adapter that fits into the driver to convert it to socket heads

slowly increasing RPM’s did the job nicely with no breaks or stripping

I felt more confident than using a typical 3/8 ratchet and socket…. by feeling the repeated small impacts of my screwdriver doing its job
rather than me breaking of a bolt.

try it out next time you have a hard one to take out

I have found a Phillips head bit in a ratchet works better than a screwdriver or impact screwdriver for the machine screws on some motors.

Im not sure how you do this without an impact driver!?

Brown Aviation SK001 Screw Knocker/Remover is the tool I use at work on airplanes (buot $29.00), I haven’t broken anything for quite some time now, rusted corroded steel hardware is removed with little effort. You need an impact gun/rivet gun in my case and some valve grinding compound. YouTube is your friend, check it out. Highly recommended!!! Second best is my new 12V Makita 1/4" impact driver. Crosbyman thanks for sharing your experience!!!

Just watched a couple of YouTube videos showing the use
of the "screw knockers" using a pnuematic / air chisel gun.
Looks slick!

Prepare to be boarded!

When i search knockers on youtube, I get some interesting stuff, but nothing about removing a screw! I would like to see this tool In use, especially with a rivet gun. Anyone find a link? Looks interesting.

Another technique i need to learn for my " tricks up my sleeve" .
One of my friends who is not mechanically inclined watched over the course of a day off and on as i tackled some head bolts that looked pretty bad and were troublesome to say the least. I wouldn’t let him see the containers of Acetone and power steering fluid,"my special blend". Then i got my propane torch out and his eyes bugged out and his jaw dropped. I had to entertain myself. 😀

Well, there is surely something to be said for the positive result of using an impact knocker or gun, can effectively loosen up the salt grip of the fastener. The down side is that you can’t really "feel" how the process is going like you can when loosening the fastener manually in a gentle fashion. In the end, I guess failure using either method results in the dreaded broken SS fastener.

I agree with fleetwins " feel" statement. Brute and quick torque like an impact driver may lead to broken bolts. I have avoided a manual impact driver till i got my 1940"s and 50’s OMC and Martin with all those slotted screws. I would never buy one of these older motors that had salt water use, For me it would take the "fun" out of working on outboards.
