errr, OK, I believe the ball flats (for wrench) are 13mm and probably need a deep well socket . The fork is held on the ball by a little clip held on the fork by a 6mm socket head bolt. so once the fork is off, an open end/box end wrench will prob fit... but I don't see how you'll access these with tranny installed and if tranny is already separated, access is easy... so there is alot of room...

PS, if tranny installed, why not just drop the tranny alone? Support the engine and remove tranny. Search here for advice in old posts.... |

You will need a 13mm deep socket. I recall having to make a special thin walled socket with the grinding wheel.
Where in Nor Cal? |

...i dont think there is enough meat for a box end wrench, its meant for a socket , Ah, sorry, didn't remember about the recess, it'd been a long time. Still don't remember thinning the wall of the socket anyway. Not too many applications on 914's of 14mm tools come to mind (valve adjust jam nuts only one I can think of now, maybe one other way back in the cobwebs...) |

its a 14mm deep. but you have to grind/thin down the first 3/8 of an inch on the end of the socket. so it will fit down the well.

14mm or 9/16" deep socket with a very deep contact area. Most sockets are broached pretty shallow, and won't clear the ball. I can get you a Snap On part number if you'd like.

Snap On "FMS14". It's a 14mm semi-deep 12 point chrome socket. No grinding. About 20 bucks. One recently sold under the old number ("S6122") on Ebay for around $4, and one under the new number went for around $9. You might look into other 12 point deep, or semi-deep sockets. What's important here is the "broach depth", the depth of the contact surface before the inside of the socket returns to a shoulder. You need the drive surface to be deep enough to clear the ball and engage the hex. I would be happy to loan you mine, but the round trip postage would nearly equal the cost of buying one for yourself.

So, you should ask the machinist how much was removed to ensure you use the correct size shim. rich |

Shim? Jeez, it aint that specific. Put another washer under it, put teflon tape on the threads as it will now leak with 2 washers under the pivot, and call it good. You just need to move it forward, you will not need to measure how far or any of that.
