    Does anyone know what the gap between the distributor drive gear and the distributor housing should be. I know there is a dimension but cannot remember what it is. I pulled out my distributor and it has a big gap and when it was new it was very tight, slight gap. Thanks for the help, Slider

    The end play should be somewhere close to .005"-.010"

    Having used a Mr. Gasket (or maybe Moroso?) kit fo this, I'd say that more than likely, you'd be hard pressed to find a washer thin enough to get that kind of precise gap.

    Besides, if you've ever picked up a few washers out of a bin and measured them, you know how much variation there is in thickness. Also, variation in thickness and surface texture would also be important, and I doubt you'd want a plated washer in this application. (would flake off, which besides not wanting metal pieces in the motor, would change the clearance)

    Can't comment on the variation of thickness on the shims or whether they are plated (don't appear to be, perhaps stainless?) made for this application, but I can say they are extremely smooth.

    Ya I know about washer variations so I went and ordered the Mr. Gasket kit. s/b here on Friday. Hopefully it does not snow tonight, but knowing Seattle weather guessers it snows when they do not expect it to /forums/images/graemlins/smirk.gif.
