Missing Head Bolt Socket Design

[FlyScooby]

To all:

 

Trying to find drawing of a cut-down thin walled socket that Skip and Bill Putney put together. Skip can't find it. I can't find it. Anybody have it?

I would like to point out this is the socket used for retorquing the head with the cam shaft in place (Bill made one, I just helped with the drawing)

No pic though

 

Easy custom tool... I made one with no welding. Simply bought a Craftsman socket (I forget the size, but you obviously know what it is) and ground the working end down to considerably shorten it - leaving slightly less than the full bolt head height of inside grip length. Then I ground the other end (the end that the driver plugs into) shortening it a little, stopping just short of compromising the ball detents, and ground that end into a conical shape - around 30° chamfer (30° from the plane that's perpindicular to the drive axis) all around. This gave plenty of relief for the socket to clear under the valve train and fit nicely to the bolt heads with room to spare.

 

Cost: One Craftsman socket plus the time to grind it to minimum material. Another tool for the Subaru special tool box. Funny thing was that when I went to re-torque the bolts, there was no tightening required, but I was able to easily engage all of the bolts heads completely to test them. This was on an '86 turbo - the head gaskets are made of a different (harder) material than for non-turbo which may have made a difference.

 

I used a Craftsman because I knew it had the best chance of holding up in its modified (weakened state). No problem.
