[updated:LAST EDITED ON 20-Apr-02 AT 05:10 AM (EST)]One of the self locking adjusting screws on my rocker arm is loose on my 223. I am afraid it won't hold the adjustment after I set the valve lash. Any way to tighten this screw up? I was thinking to try to peen the threads with a drift after adjusting? I don't know if Locktite would work or not. Thanks.

 

 

I am overhauling a 1960 ford 223 and i need the tappet settings before i can assemble any further. Do you happen to know what the settings are? thanks alot... Dan

All lash adjustments are made at TDC. This info comes from 1960 Ford Truck shop manual. As for the adjustment screw, tighten it til you feel resistance. If it takes less than 3 ft/lb to turn it further, replace the screw. If that don't get it replace the rocker arm,too. If you need more you can e-mail me and I will help out all I can.
