Default Re: How to check dist/oil pump/ timing gear backlash?

distributor/oil pump drive is a visual inspection,oil pump drive tang should be flat with no edge rolling.

the drive cam gear should not have 'hourglass' teeth

.004 on the cam timing gear can be done with a flexible magnetic base and a dial indicator but its a pain.I do it by feel,a 'light click'.
