Oops. First, thank you for posting this information. Just one final somewhat related thought from my own bad experience. If you use some kind of washer to shim the end play in the distributor, make sure that whatever size washer you use has an outside diameter SMALLER THAN the root diameter of the distributor gear. I made that mistake and tore up a perfectly good set of gears by using too large a washer OD.

Yes, thanks, if shimming Distributor Endplay the OD of the Shim must be less than the Gear Root Diameter.
Her's a random "sideways" crazy thought... Wonder what an AMC V8 Gear and a Small Block Chevrolet Distributor Gear look like side by side? Wonder if the Shaft Size is the same, tooth count etc... EDIT: some surfing found these dimensions, unconfirmed: EDIT: updated with info from bobsterfl - Thanks ! DISTRIBUTOR SHAFT DRIVE GEAR (s) 0.491" Dia. = AMC Distributor Shaft, Delco & ? Type ( 13 ) = Number of Gear Teeth 1.040" = Gear Teeth Outside Dia. 0.785" = Gear Teeth Root Dia. 0.620" = Gear Teeth Length 0.491"?Dia. = SBChev Distributor Shaft (update 10-27-18) ( 13 ) = Number of Gear Teeth 1.25x" = Gear Teeth Outside Dia. 1.0xx" = Gear Teeth Root Dia. 0.71x" = Gear Teeth Length Edited by PHAT69AMX - Oct/28/2018 at 12:37am |

OK, I just went out in the garage and measured an OEM distributor gear that I have, and here are the dimensions I measured: (All +/- based on my cheap dial caliper)
Gear OD: 1.040" Root Diameter: .785" Gear length: .620" Hope this helps. Bob

Thought no harm adding this overall AMC Block Oil Circuit Diagram here:
( guess this drawing does appear to show the Timing Chain Sprocket Front Face Oil Groves )

And it left off the fuel pump eccentric and distributor drive gear so it doesn't show the oil feed passage to the drive gear..... but shows all that WASTED oil slinging out to the timing chain and starving the Distributor gear. Jerry |

Yep, agree, that video shows it plain as day...
Right now I am bumming out because I no longer have parts and am unable to find a picture of a Timing Cover on a Block without the Oil Pan on the Block so I can get a visual of the Timing Cover & #1 Crank Bearing Cap and resulting Oil Drain Back restrictions or limitations, if any...
