Re: [T3] rotor play


CurtR=> i can wiggle the rotor about a quarter inch

It's probably OK, but it's possible that there's some wear and/or
maladjustment that's making it a little sloppier than it could be. You can
look for this where the distributor meets the distributor drive.

When I install a distributor I always check to make sure the drive dog at
the end of the distributor shaft looks good and isn't flopping around. There
are some shims down there to make an almost-tight fit, and after years of
use they are often worn razor thin. There should also be a fiber spacer
washer, and this is often worn thin or plain missing, which will make for a
floppy dog.

The dog is a bit of a pain to get off (remove the spring and drive out the
pin with a punch) if you need to replace those washers. I also sometimes see
drive dogs with nubs that are worn down quite a bit from abuse of one kind
or another. You want them to be pretty square so they fit better in the
distributor drive. I don't know whether these parts are available new, I
just collect good ones from bad/spare distributors.
