[R-390] Drawing and parts list

[Paul Galpin]

Hi All!

I am in the middle of re-building my Amelco gearbox. Wanting to be sure of where bits go, I printed out the "Zoning for RF Gear
Train Assembly Fig 6-36" list, and Fig 6-36 itself.

Nothing seems to make sense!

For example, in the drawing, No 60 is clearly a gear assembly, but it is listed as a 2 - 4 MHz cam o313-1. 
In the Sect 7 Parts list, o313-1 is also a cam, Index No 60.

It seems that the Zoning list and the Parts list agree, but the index numbers were put on the drawing at random - or am I completely
misunderstanding the system?

Are the numbers on the drawing the Index numbers - or what?

Can anyone explain?
