New woods bushing lifters

[Ohio HD]

The clips only job is to hold the lifter together when it's out of the motor. When the lifter is installed and adjusted, the cup is nowhere near the clip. Usually about 0.100" to 0.140" away from the clip.

The Circlip is not the right thing, you want an internal TruArc see link.

Upon install you need to note that the TruArc has one side with a rounded edge and the opposite has a sharp edge. These are always installed into the lifters retaining ring groove with the sharp edge side facing up. This reduces the chance of the TruArc being forced out by slippage of the round edge against the retainer groove.

This is something used when the lifter is adjusted with the preload position placing the cup near or at the top of its travel. It's an old hotrodder trick to remove the chance of pumping up the lifter then having to wait for it to bleed down before the engine catches again.  For everyday operation the plunger and cup body if adjusted to factory specs shouldn't be pushing against the retainer. But if you wind it out to where you pump-up the lifters the TruArc is damn good insurance.

Wood Lifters use a wire retaining clip. The same clip that all Harley Davidson OEM lifters for Twin Cam and M8 motors use. Some aftermarket lifter manufacturers use an internal snap ring, some use the wire retainer. One is no better than the other as we already know they are under no tension once the lifter is installed and adjusted.

You can use which ever method floats your boat, but one is as good as the other.

I have never had a retainer come out of the lifter body.

Wire style clips are used in a radiused groove. Stamped clips (Truarc) and spirolock clips are used in a square cut groove.

I didn't know that. But it does make sense.

If you check wfolarry's lifter threads, you will see that he makes mention of some S&S pushrods making contact with the circlips and he replaces those with the wire clips.

So curiosity got the best of me, this is a 18538-99C lifter, this lifter uses the wire retainer. The groove in this lifter looks to be a square cut. I tried to use the light in my scope to get a better image, but the internals of the lifter just reflected light all over the place.

Smith Brothers came out with a new stiff wall tapered adjustable non quick change pushrod around 2013-14 that did it on high lift cams.  When I got mine only a few sets had been released. This was on S&S premiums with wire clips.  Another member here and I brought it up with them (there's a thread here about it).  They redesigned the lower adjuster ball profile, replaced ours immediately 👍 and as I understand they reconfigured all sets from there forward with the new profile.

below is the -99C Lifter I had sectioned, looks square cut to me 

[wfolarry]

It's the same groove whether it's wire or clip.
There's even a pressed in retainer in some racing lifters. I don't like them because it's brutal taking them apart.

That's true on pistons. If you don't know which retainer to use check the groove or the shape of the end of the wrist pin.

Well got platinum lifters in ,

 i just had a nagging gut feeling on the cup design so i took the cups and disks from the woods lifters i had and put them into the platinum lifters , oil comes out just fine , all Measurment's were exactly same , made from same place just did not like having a tiny hole barely visible hole being the meter and feed to top end , it just didnt sit well ,  i have heard stories of piston jets clogging or push rods and both have large holes than this cup so i started all sounds great went .140 preload so after engine warm be sitting at .100 or so but so far so good. i know im probably wrong but the meter disk has worked for long time.

Did you miss what Larry said about why the hole is so small, and what will most likely happen?

I for one wouldn't spend money on a premium product and then change it based on a hunch. I know that Jamie Long has many sets of these Platinum lifters in the field right now.

here is a pic of the one i took out and the one i put in,  sorry but i couldnt get better pic the hole is small

the premium part to me is the roller with no needle bearing otherwise they look exactly like the previous woods lifter , ya i know why hole is small to meter oil just dont like it just my opinion and im ok with the older cup version,  ive had issues trying new stuff like the SHUBECK ROLLER-X lifters back in the day full floating but made out of aluminum coated, didnt workout to weel fo a few peoplw 

[Ohio HD]

The point is you may have changed the metered amount of oil expulsion and as well then changed the way the lifter body stays pressurized. I suspect they made a change for a reason. They already had the older style oil metering valve and cup to use.

I would not at all recommend swapping components from earlier lifters, the Platinum solid bushing lifters were designed to meter and oil a specific way. Zero reason to do this. 

[Hossamania]

I'm not sure why you'd want to use them if you don't trust them as built, and why you trust them with your untested mod.

[itsafatboy]

OK i am going to put the cups back ,

[itsafatboy]

How is the bushing getting oil on these lifters ,  are there the 2 small holes on the lifter body , like the alpha, and like the ones layy sells

No comments on the lifters but kudos to Bobby and Larry for being upfront about their source. We have all seen countless shops and reseller call things 'Their Lifters' or their pistons, pushrods, cams, etc, when the only thing that is 'Theirs' is the sticker and card in the box. <rolls eyes>

This looks like a good product and I am anxiously looking forward to reading countless new threads about them.

[itsafatboy]

well the more i looked i just couldn't ,so my choice, i have oil to top end and head temps were great on 80 mile drive yesterday and the lifters are quiet real quiet, so i will keep the cups from the alpha set, just dont like the small half a needle point hole , doesn't sit well, hope they last forever though
