do S&S quickie push rods need new tubes

[1340evo]

do S&S quickie push rods need new tubes or will they work with the existing ones? I did see something about cutting the tubes down to gain access to them, but diameter wise, is there enough clearance?

[Ironheadmike]

I used them numerous times with stock tubes and no problems

[1340evo]

okay.. are they a good option or are normal adjustables any better?

The "Quickee" is a good choice for most street applications, I have used a lot of them over the years. I only had one failure with a "Quickee" pushrod, ever,  about 15 years ago. It was a TC, big bore engine with .650" lift, bigger valves (2.100") and springs. The springs were about 600# open force as I recall. The tube section bent on one pushrod, the adjuster stayed straight. Replaced them with tapered Smith Brothers pushrods.

Is there any other quickie type worth considering?

Exactly, Smith Brothers. Also custom branded by SB for Axtell, Fueling and Zipper's

S&S are the best value.. £150 landed.. the others are over £250!... so think I'll go S$S for now    93-5120 appears to be the right item

Can't see a thing on Garfield...

So I have Hylift Johnson lifters... what depth do you aim for with these? .100" ?

[kd]

IIRC they are less travel. 

[1340evo]

The manufacturer says .030 preloaded?
I've seen people quote .070
And Fastlane Headwotks in the UK who sells these in the UK and uses them on hid builds, says .140

So totally not sure. Got to say the manufacturers advice is the one I'd usually follow but does appear a bit lite.

I know people who know people.

   I forgot about Garfield's Garage. I remember when FSG started to stock them.

These pushrods had about 18,000 miles on them before I ever had them in my hands.

I've always used S&S or SE. I have nothing against Smith's, but... two threaded parts with two opportunities to unscrew? What exactly is the benefit in that?

They do look nice..

On the pre-load, I'll measure the travel in the units and set mid way.. do you think that will be the best idea?

[wfolarry]

Set them @ .140

[1340evo]

Set them @ .140

Hi .. I'm guessing your a engine builder also. So that's two people using them saying .140 !  by all accounts it make them less noisy.

So what the hell is the manufacturer quoting at .030??

[rigidthumper]

Measure total travel of the lifters you are actually using, then decide. Some lifters have short travel, so their 1/2 way point would be less than standard lifters. Most have .200" +/- 10%

[kd]

I was hoping we would hear from Larry.  He is a site supporting vendor that has been supplying members with your lifters.  He has extensive experience with them and his advice is good.  I would follow his lead on this. 

[1340evo]

maybe a new post would draw him in as its not really about lifters.... ?

[rigidthumper]

He was the one who said "set them @ .140"

[1340evo]

He was the one who said "set them @ .140"

Okay, thats good then.. no more info required. 2 shops saying the same... .140 it is...

[rigidthumper]

Measure 1, just to be sure...

[1340evo]

I'll do that tonight.. see what they are 

Update.. checked at .207 " so .140 suould be fine although quite a bit of spring pressure at that?

Wonder why the manufacturer states .030 ??

[wfolarry]

The manufacturer states .030 because that's what they're set at in an automotive application.
For a motorcycle the lifters are the happiest when set to the middle.
1/2 of .200 + .040 [to allow for growth] = .140

[kd]

    Plus the deeper adjustment may be helpful with hot starts at fuel stops etc..

[1340evo]

.140 it is... thanks for the explanation.

Just making a fly cutter to do my heads so when the rods come , its ready to go back together. they are in Kentucky right now
