I had to take appart…a second time…….  my  sealed gearcase on a cd17-18

 

whenIwent to  remove the  Philipps head pivot pit #38 on the shift rod   I stripped it     OMG!!!! 

I tried to saw a slot  and use a flat screwdriver to no avail…..got worse and worse… not pretty

So….. anyboby have suggestion for me for removing a maggled philips headed  bolt  before I move on to drilling …..

I had  screwed it down  what seemsed to be normally….  with a dab of gasket  (Permatex black) goo to seal it  but it looks like  that was my mistake.

and…. will be looking  for a spare pivot bolt if I sane the  housing threads

 

I’ll try anything.. thanks

I suppose it’s too late to try a hand impact screwdriver?  Unless somebody has a better suggestion, how about a left hand drill bit?

P.S. don’t feel bad.  I’ve had the same situation.

[crosbyman]

tried impact… no go    will try left hand drill  ( to be purchased…)  I’ll see if anyone else  comes up with a cure

 

thanks

Do you have a Dremel?  If so, you can cut a slot in the head to accept a flat head screwdriver or a bit for your impact. If the head is really bad, they can be removed by carefully working the outside edge with a small and sharp cold chisel.  Bin der, dun dat.

I don’t really know what they were  thinking when they made these screws with a tiny Phillips socket.  Maybe the designer was an ex watch maker?  If they had used the proven Robertson socket, the screw could be removed a kazillion times and reused instead of  stripping out on a first attempt and  necessitating the purchase of a new one.  Or maybe that’s what the original plan was.

crosbyman back when I was a pup we had problems just like yours with motorcycle case screws.  We used a center punch.  Find a spot on the head a little off center drive the center punch into the head until you have a small divot.  Next tilt the punch a little to turn the screw counter clockwise.  Medium size hammer and Maybe you will get lucky and it might turn for you!  This trick worked miracles for us sometimes.

Gentlemen….. we have success   & it  took  2 minutes  with a real pointy nail set punch.  I figured the circular edge of the nail set punch woud grab the  bolt head better and BINGO… movement.. after  3-4 wacks

I can now move on to resealing the GC  which needed  a shift rod oring , propr shaft and… drive shaft seals.

thanks for sharing your experience   🙂

Hey!   That’s great to hear!    BTW you can make one of those pivot bolts.   Just need a bolt or a screw with the proper tread.   Carefully grind or file the treads off the end that goes into the shift fork and housing.  Don’t ask me how I know this.   Some of us are pretty cheap I guess!

Glad it came to a quick and easy resolution.   Always feels great when you finally remove a broken, seized or stripped screw or bolt!
