valve adjustment - sherman lifters

wayne hutton · 04-08-2010, 09:18 AM

what process do you use to adjust valve lash on these things, 302 stocker sherman lifters ,screw in stud w/poly locks. The card that came with them said .013 to.015, set to -.005. That was farily easy on the engine stand with dry lifters you could feel the .013 spring deperssion and with a dial indicator on the spring you could collaspe the lifter and backoff the .008 to get bach to -.005. Now the engine has been run and is in the car need to reset lash. The lifter now has oil under the cup, hard to feel the small spring depress and almost impossiable to get to each valve with a dial indicator. ther must a better way to do this.

ps excuse my typos and spelling not much at this keyboard thing

thanks

Not to highjack this thread I to would like to know how these valves are adjusted in a sb stocker? TDC, EOIC, turn the pushrod method etc?

Thanks

You think they are hard with screw in studs and poly locks, you should try it with the stock rockers and those #$@%!!! shims! I'm not convinced im even close.

I set mine with a .002 filler gauge just like you would a solid cam. I'm sure someone will say that's not right but that's how I ran the silver car for years.

Adjustable pushrods with the stock rockers, time consuming but MUCH easier than those shims you are so fond of............................

I highly reccomend the EOIC method and turning the engine over with a wrench, not the starter.
Greg, you will probably find a zero lash, once the set screw is set, will yield .002" which is perfect in my book. I figured that out one day and couldn't believe the amount of time it saved. I had ARP adjusters and all 16 came out perfect. It was far more accurate (after testing with a go-no go method) than trying to get the feel with a .002" feeler gauge.

Acronym alert, EOIC, at the cost of being stupid, what is it?

exhaust opening, adjust intake
intake closing, adjust exhaust

Thank you. Was pretty sure it was something simple. I'm going with the Shermans on my crate stock engine. so, this will soon be an issue I need to understand.

Cliff will tell you, you have to adjust them a couple of times to get them "dead on". I use a .004 feeler gauge and make the first run through as close as possible, setting them by firing order. i start the car, bring it up to temp. shut it off and pull the covers, run through the valves again, by firing order to double check. you may have to "cheat" the lock nut to snug some up. i have never found any too tightm only loose, but it could happen i guess. then after 1 or 2 passes at the track, i pull the covers again for a final check. you MAY find 1 or 2 this time. reinstall the covers and run it. I havent tried the EOIC method on these stocker style engines, but i havent had any trouble either.
