Hi Eric

That is surprising as the type of clamp that is used here usually requiers very little fore to keep tight. Mine uses an allen key ( 6mm ) and hand tight is more than enough. MAybe your grease is settling and it just apears loose? I turn it until I can't move the washer around witht he tip of my screwdriver and tighten the clamp there, never had i come loose.

ice: Your project for this weekend is... re-adjust those front bearings! Loosen those clamps and turn them enough so the thrust washers can move side to side with some drag! Back in the '70s PCA used to require, at an event technical inspection, that there be no play in the front bearings. Eventually, because of me and others, they began to relax that rule to allow slight top to bottom play using the wheel/tire assembly (never side-to-side because that can involve the tie rod). The problem is that the heat in the bearings, generated in a practice session or a race, can cause enough expansion to take away a small amount of play. For street driven cars like yours the factory instruction is to let the washer move sideways under light screwdriver pressure, but not enough to cause axial play in the hub. It's a very fine balance, and I've always felt that a small amount of play, in order to achieve washer movement, is better than no play/movement at all. You obviously understand the tightening procedure for the clamp bolt, but the spec is 10.9 lb/ft (1.5 mkp). I've seen those clamps so overtightened that we had to discard them and use new ones! (Always re-check the washer after you torque the clamp bolt!)

thanks Pete

My thrust washer does move with a light screwdriver pressure. I tightend it as I had described , but i JUST couldn't move it, I iwll reinspect and look for a little play.

PS those injector inserts were fun >>> have 2 out of 6 done so far ...
