Something I'm working on, decades of discussions, part pictures, and descriptions,
but think I have yet to see a section view line drawing showing the
AMC V8 DISTRIBUTOR DRIVE GEAR OILING OIL FLOW PATH...
The apparent "Achilles Heel" of successful aftermarket AMC Part Manufacturing and Fitment...
Sure do miss having working 3D AutoCad software...
07-31-18 Drawing Updated R-4 - Add Rear Cam Journal Oil Vent Hole, etc
09-03-18 Dwg Updated R-5 - Show "non-stock" Sprocket Front Groove(s) Oil.
Feedback appreciated... 

Rev-5 Version 09-04-18


1st Version 07-26-18




Line Drawing & picture showing OIL NOTCH in back of TIMING GEAR



Here is a very good VIDEO graciously made with considerable effort by 401MATCOUPE
which presents a clear visual of the oiling and the "questionable" (non-stock apparently)
Grooves in the Front Face of aftermarket Cam Mounted Timing Chain Sprockets.

Video also mentions the importance of the Crank Oil Slinger (crank oil shedding).

Visible Oil flow volume may indirectly "support" reasoning for Drain Back Modifications
that can be done to the inside of the Timing Chain Cover "Ridge" and/or
the Front Crank Main Bearing Cap (increased drain back clearance gap):

Nice of them to have that method of positive gear lubrication. Many engines just hope that enough oil gets splashed on the gears to keep them happy. AMC thought ahead on this one.

Nice illustration!

Don't forget the oiling grooves in the timing gear that sprays oil between the timing gear and fuel pump eccentric.

That Looks Great!   

Only minor point is the "Start point in the Cam Journal is "Up" around the 11 oclock position (when keyway at 12 oclock) when the oil passage in the Timing gear is at 6 oclock   You show it at 6 oclock on the cam journal.  The flow looks dead on.  (And thank you for leaving out the "slinger grooves" that are stealing the oil volume and causing the problem)

Yea, these slots that I braze shut.  The worst one is right at the transfer slot.

I modify them as well. I weld them up, have it machined flat then put two shallow grooves in away from the keyway and oiling feed areas.

Could someone be so kind to post a Picture of the Front Side of
a known STOCK 1969 AMC V8 Cam Timing Chain Sprocket / Gear?

Thanks for the comments, working on revising the drawing.

Considered showing the front Timing Gear "oil slinging grooves" but...
wanted to avoid "clutter" and show only Distributor Gear Oiling Path
and I fail to remember seeing those Grooves in stock OEM AMC Timing Gears
but no longer have old used stock parts on hand for reference or pictures.

It is the bottom one with no notches and missing nylon teeth.

http://theamcforum.com/forum/timing-chain-gears-question_topic67102_page1.html

This is the factory heavy duty one that didn't have nylon gears.

Yes but, they were very small.  The after market slots are way too big.  The True Roller brand changed and now they have way to big of slots too.
