Is T.I. distributor pole piece adjustable?

[Mark G.]

Removed my T. I. distributor to replace the vacuum advance. When I rotate the shaft, one pf the points on the stationary pole piece hits the points on the shaft. Before I mess something up, can I loosen the three pole piece screws and move the pole piece so it no longer hits? Is there a spec for the clearance between the points? Thanks.

I don't' know of the spec for pole piece clearance, but shaft side play should be no more than a thou or two, and when you wiggle the shaft back and forth play should be virtually imperceptible. As long as you have it out, you should overhaul it. It's an easy job if the housing bushings don't need to be replaced. The procedure is in the COM, and I started a thread back in Dec. 2012 on overhauling a L-79 single point distributor. The TI dist. is basically the same except for the stationary pole piece in place of the breaker plate.

Use a business card to set clearance. Loosen the 3 screws & place the card where it's hitting. You may need a couple of tries before you get it right.
Gear to casting clearance is critical for K66.

Thanks for the replies. Looks like a Saturday job. I'm waiting for endplay shims.
