67 bb T.I. distributor

[Ed P.]

I need a good exploded view of a T.I. distributor only. I think I may be missing some parts. Under the big brass washer on the upper bushing there was nothing. No source to lube the upper bushing. Cavity was clean and painted. Thanks Ed

The cavity was packed with a mix of heavy grease & sawdust & the top was sealed with a special cupped white plastic washer available from CC.

Ed --- as Ken has said, should be same plastic seal.

(from 1965 Corvette shop manual, 6Y-13) --- there's an exploded view but not in the area immediately below the brass washer.
But the text says: "K66 Disassembly . ....As a unit, remove entire magnetic pickup assy. from the distributor housing.
Remove brass washer and felt pad
(at overhaul) the seal is removed, add SAE 20 oil to the packing (sawdust or whatever) in the cavity. New plastic seal then required".

I have only the lower housing of a 1111093 ('65-6 425hp BB w/K66), with the brass washer missing. The plastic seal underneath looks exactly like a non-T.I. upper bearing area.......

But I have to admit that I'm confused by the GM parts catalog exploded drawings. Is there or is there not a felt washer on top of the white translucent plastic seal, and if yes, is this felt (also) given a drop or two of oil ? Only for points distrib's ?

The T.I. cavity under the brass washer I have looks nothing like the cavity of a points distributor. The cavity is only about 1/8 inch deep if that and machined smooth. By the time I install the plastic seal there is not much room for grease. Any pics of a T.I distributor housing cavity area.This is the first T.I. distributor I have done. Have done several points distributor. Ed

A 1962-74 TI distributor and a 1962-74 points type distributor used the same distributor housing with only these two exceptions:

1) distributors for FI

2) ball bearing type distributors (SERVICE-only)

Well no wonder I am confused. I will take a pic and post it here. Ed

And here's the ball bearing distr. 1111263. The stationary pole piece (magnet, coil) is fixed to the lower housing.

Ed -- here's my "093" [dated 5_J_20 = Sept 20th, appropriate for an early '66 L72] with white/translucent plastic seal and upper brass bearing still in place. Sure does look like sawdust under there .

I don't understand this one, at all. The cavity was not machined out (except for the very top where the seal installs). The cavity was a feature of the casting, itself. Did you remove the upper bushing?

Also, someone has been in this distributor before. The inside surface of the housing is usually not painted and, even if it was painted, it would not be painted with a paint this thick.

Re: 67 bb T.I. distributor

Yes I removed the bushings they are worn so bad that the pole piece tips are hitting the magnet pickup. The upper bushing is real bad, I guess from no lubrication. Ed

Re: 67 bb T.I. distributor

Ed, isn't this a 65 housing because of the bottom oil groove not being all the way around. Scott

That configuration may have been used after 1965, possibly through early 1967. However, as far as I know, that feature is unrelated to the lack of a lubrication well.

Re: 67 bb T.I. distributor

I thought the oil groove not being all the way around was big block only. Ed

Well, the same design was actually used for VERY early small block, too. For big block, it was essentially used for only the 1965-E67 oiling system. However, it can be used on any big block. By the same token, the "full round" configuration can be used on ANY big block or small block.

As I mentioned, this oiling feature is not related to the lubrication well configuration. As far as I know, all 1962-74 Corvette distributors (except the ones I mentioned above) have the lubrication well. I have no explanation for the configuration of your distributor housing. Whether or not any distributors were intentionally made the way of yours, it's an extremely poor design and I would not use it as-is.
