Roller Lifter Links

Post by Jay Bradel » 04 Mar 2019, 09:32

Has anybody reproduced the links used on the roller lifters?

Tech support at CompCam says the links used on the Endure X #829 is 302 S.S. 3/4 hard with a proprietary coating on them. I could not find a supplier that has stock so I cut a link up and had it analyzed. The results were that the material is 301 S.S. and the hardness is 36 RC which is between 1/2 and 3/4 hard.

Any thoughts?

Thanks, Jay

For what application are you not able to buy links? Is this for Comp rollers in a Studebaker?

Jack,
This is for a Studebaker block. From what I see there are webs in the block that prohibit the lifter set to be installed. I tried every way to install them without grinding the web. So I thought about making a set of links that are slightly "V" shaped.

What am I missing?

That roller lifters with captured links are not your best option, although, there's nothing wrong with grinding the block webs for clearance.

There are several other manufacturers who use roller lifters with removable slotted end links. At Alan's recommendation, we use Iskenderian. I'll get you the part number.

My roller lifters have links with a rectangular notch slot that clears the ribs in the upper block. But also have a set and the links are flat straight across and require rib grinding of the block. Both set of links are removeable from each lifter. I sent out the pattern to someone but can't recall the person.

What is the brand of lifter you used?

I am thinking of making special links for the Comp Cam lifters but would rather purchase another brand of lifters that will work without grinding the webs in the block.

Believe they were comp cams. But years later when I ordered a replacement set the same lifter number had the straight bar links. If you can picture two L shape bars connected together in the middle with a rectangular box that is open on the top side. Pretty simple but not a V. A little jiggling of each lifter and the pair drop in. Let us know if you machine up a set. Pretty sure others could use the correct drop in links.

Also a V design might not clear without a fight. The open rectangle requires some jiggling to clear as is.

I made this prototype and is seams to allow assembly very easily. Now making a set for Phil Harris and myself to test in a running engine.

Hi, Jay,

Nice work and I should take time to learn how to use those design programs; maybe in the next time on the wheel.

Just asking, what benefit is there to having to manufacture custom lifter links when there already exist drop in designs?

Good question.................. I have not been able to find a set that drops in without grinding the webs. If there is such an item then I would much rather purchase that particular brand.

Would you happen to have a part number?

Thanks, Jay
