sherman lifter help
 

i have a set of sherman lifters in my 92 mustang 5.0 l/sa. i can't get these things to work. the instructions say to set them with .002-.005 lash.i set them at .005. after 3-8 passes they start to tighten up and hold the valve open. is this the way they are and need to be adjusted after every pass? help!!!

Re: sherman lifter help
 

Not @ all! I have a set in the 6cyl in dads car they were set in 06 & haven't been touched! we set them with a filler's guage @ .002 cold just like you would a solid? that's a hyd roller you have so not sure but should be the same? you have a good set of poly-locks?

Re: sherman lifter help
 

brand new. new springs the works. they did the same thing last year with stock rockers and fulcrums that i shimmed for clearance. the new heads are stud and polylocks with early ford rockers. wonder what is wrong?

Re: sherman lifter help
 

I suspect you're not were you think you are on the cam lobe when adjusting valves. Stocker cams are REAL touchy. Bumping the engine with the atarter is a good way to screw up valve lash adjustment. I would suggest EOIC while rotating the engine with a wrench.

Re: sherman lifter help
 

I'll 2nd that...stocker cams are "funny" we "rock" the cam a couple time to make sure it's on the base circle.

Heres also what I feel is screwing things up. I had similar issues like this one.I feel the lifter is bled down when you are adjusting the lash! It will tighten your lash when the lifters fill back up from oil.(ex engine runs for a minute). I would loosen things up, start the engine do one side at a time (quickly as to not let the oil bleed out) then do the other side. Now if this does not work I can tell you the lifters are junk. Trust me as im not going to get into the full details but I have taken these lifters apart and was very suprised at all that makes them work or not work. Also call Allen and tell him the status and they can guide you more. Hope this helps Mike

Re: sherman lifter help
 

check the lifter for the plunger to be topped out at the plunger retainer,with no push rod on it,(mite be missing the spring) gmonde
also if you not on the bottom of the cam when adjusting lash you would end up with a loose rocker,,,,,,,

Re: sherman lifter help
 

thanks for the help guys. going to get this going yet.

Re: sherman lifter help
 

Have you checked for clearance between the rocker, and the spring? I run the Shermans with stock rockers, and have had no issues?

Re: sherman lifter help
 

Bob, these lifters are a little more tricky to adjust. You may have to set them after your 1st couple of runs. They do "seat" in and stay adjusted very well. I'm very pleased with my set and Cliff's "after the sale service" is second to none!

Re: sherman lifter help
 

I had the same trouble. As you bumping the motor over the things building pressure and pumping up the lifters. "Set it like a solid" now becomes pretty hard when things are moving around. I got mad and started setting them at .010 and or .015. When you run the motor over 3-4 revolutions it would close up and have like .005. Loose or tight did nothing for ET at all for me anyways. But im running another set this year and will be "setting them like a solid" again. :rolleyes:

Re: sherman lifter help
 

plenty of clearance between the rocker and spring. running behives.i got some top secret help with these so i'm going to try his way. on question i have is wouldn't you be able to adjust them according to the firing order? or does the cam duration make that not a good way to do that?

Re: sherman lifter help
 

I always adjusted mine by firing order.

Re: sherman lifter help
 

I run sbc hyd shubecks. I have never used Sherman's lifters I take they are adjusted just like Shubeck's? How do you compare the two? Which do you guys prefer? Last does Sherman have a web site or a contact number?

Re: sherman lifter help
 

I know I am going to sound stupid for asking this but what does EOIC mean.

Re: sherman lifter help
 

Alan,

When the Exhaust starts to open (EO), adjust the intake lash. When the Intake valve closes (IC), adjust the exhaust valve. Some people prefer firing order, others prefer EOIC. Either way works if you're consistent, although some people will swear that one or the other gained them mucho HP.

Re: sherman lifter help
 

Jerry, Do you adjust the exhaust valve when the intake just starts to close or when it is fully closed? I do the exhaust when the intake just starts to close, is this correct?

I've had great luck with these lifters, call me if you have any more questions. 201-376-3069.

Re: sherman lifter help
 

Bob, thanks for the contact. How do these lifters compare to shubecks in a traditional hyd. flat tappet? Can you run the same seat pressure? Can you use the same set from cam to cam? Thanks for the info.

Re: sherman lifter help
 

You can't run the super high rates and you can't change them from cam to cam. But they are cheaper.

Re: sherman lifter help
 

Made 4 really good passes with the mustang 5.0 and after the fourth pass I heard a noise going through the finish line, sounded like a quick rev limiter bounce (but I had no rev limiter set that low) going through at 6500. Was making a bad noise driving up return road, I pulled the valve covers and noticed 5 roller rocker adjustment nuts had backed off almost completely. Tightened them back down but the car didn't run anything close to the previous 4 runs. Did I lose a lifter? Compression test passes and didn't see anything wrong with springs or pushrods when I pulled them out. Rockers weren't damaged, just loose.

Re: sherman lifter help
 

Bobby,

I had something similar happen at the last race last year. I run tool steel lifters so no puck issues. But I thought I lost a cam lobe. I verified lobe lift and all was fine. What I did find was my OEM replacement distributor reluctor wheel had loosened up on the roll pin that secures it to the shaft. It had slop in it and was playing heck with the timing. Crappy Chinese material on the reluctor casting.

If adjusters were found loose, there may be something else to be looking at. Just some thoughts. Good luck

Re: sherman lifter help
 

Bobby,

As Sean says check the cam lobes really close, to make sure there's no wear ?? Also, the lifter bottoms for cupping with a straight edge ... I had the same think happen last year, it was a pushrod had gone thru a stock rocker at the 1,000' mark ....Took the top apart to be sure there wasn't any damage inside also drain Oil & filter and check ....May sure you check the spring pressure, to be sure it didn't float & hit something ? Now's the time to be safe & check everything before it gets real expensive .... I was lucky, it was only the rocker arm & harden pushrod's did their job....Checked everything & replaced the rocker arm & went fast again .... Good Luck ...
