The Stovebolt Site Forums The Shop Area Paint and Body Shop Clutch drive screws ?

Its been awhile but am back on the doors on my 59; need to remove the window assy . There are 4 clutch drive screws I have a 1/4 to small and a 5/16 to big driver. They of Corse are rusted. any ideas on removal? vice grips may fit on the two for the crank but the other two are in a recessed area. can i grind a old phillips in to a clutch head?

I trimmed up the driver. I bought it at napa and it was like a half size in between. Like.you, it was too big. I had a clutch head fitting for an impact gun and that breaks em loose. Pretty much anything you can get in the slot will work once I ended up replacing the clutch head with pan head bolts from fastenal

Sometimes a flat blade screwdriver will fit tight enough to turn one out.........on occasions I have took a small cut off disc and cut a horizontal slot in them and twisted them out....and remember, always try to "tighten" them first. Sometimes that will help brake them loose. Of course if you find a clutch head bit to fit an impact wrench as David said above, a good whack will do wonders....including twisting them off. If that happens, just drill them out.
If all else fails, grind the head off then twist them out.

Spray the head of the screw with a solvent of your choice, then use a dental pick to thoroughly dig out any debris in the clutch head area. I don't know how the different sizes are numbered, but I do know that someone makes a clutch head bit that will fit your window assy screws.

Well I tried the visegrips and two bolts came loose, made a bitt that would fit in the other two and started to strip the holes. thinking if a quick weld of the tool to bolt and seeing if that works. Mosquitoes say its time to go in for the night.

Heat is your friend when getting rusty screws out. Heat them till they glow cherry red, then try again. Alternate heat and penetrating oil for the really tough ones.

After you weld your tool to the head, it will nearly fall out. A welder applies the perfect amount of heat in a very specific spot, and the screw comes right out.

Not to hijack the conversation but I found there's a huge difference in the quality of clutch head bits. I recently purchased some used Proto clutch head bit sockets and they fit the clutch head bolts very well, nice, snug, solid fit.

Well I tried the bit again and it ate the head out. so I drilled the las t 2 and removed the part from the door. it was rusted badly so will drilland tap it. good news the rest of the door window removel went well... off to sand blast mon am. Thanks for the support
