Re: How to check dist/oil pump/ timing gear backlash?
Timing gear is on the timing gear and crank gear. Ford specified a small backlash, however my own engine with 35,000 miles has none, and there are no problems.
The distributor lash is easily checked by moving the tightened distributor rotor back and forth. That one doesn’t matter too much because the lash is removed when setting the timing and the engine turning always keeps it at zero. If the cam/distributor drive is out you can look at the gear wear.
