Valve spring compressor

[scott657]

I had a little time on my hands today.

Cool! Make the rocker shaft hole an open hook and use an old shaft to do them all at once.

 

[scott657]

great idea

 

[Righty Tighty]

Very cool. Does it lock in place once you have the spring compressed?

 

[scott657]

no

 

[Righty Tighty]

Cool design either way.

Had to make one today as well, my old one didn't like the mechanical roller springs I'm installing.

I like yours better than mine the problem I have with mine is the gap is to small and I cant fit my fingers in it to put the retainers back on I'm gonna modify it to work eventually but I really like your idea better I may scrap mine and try yours lol

I chose a c-clamp instead of the f-clamp for a couple reasons. The first is that all my f-clamps are too expensive to sacrifice. The other is that I like the threaded rod to capture progress, as opposed to the friction/pressure that the f-clamps use.

Whatever works though, right?? Anything is better than those cheap spring compressors that fly off with the slightest bit of pressure.

I thought about this design but I wanted something to replace valve springs with the heads on. I have to run a lighter spring during break in then change them after I dont want to pop the heads off just to change springs

That’s a great point that I hadn’t thought of. I made the tool out of necessity during a complete rebuild, so the heads were already off. Looks like I’ll be following your design in the future if the opportunity presents itself!

I got to do some modifications to mine when I get the chance i have a million projects at once going lol

 

[scott657]

I had to modify mine a little to center the pressure closer to the center of the retainer. Actually it was kind of a lesson on rocker arm geometry

Yea I gotta do the same on mine I'm gonna change the angle of the arms a little when the are fully depressed it holes the retainer at an extreme angle

Not home made, I forget where I pick this up from but I did notice it at Mancini racing. A little pricey if seldom used. Not a problem in this house... LOL

I like that 1

I like it a lot. It works very well. You just have to keep the tool properly placed on the retainer and take note while you compress the spring. The spring /retainer does t always go directly straight down. It can catch the valve tip or the side of the valves little rough if your not careful. Not that I damaged anything yet, but it could if you went gorilla and not looked. I recommend this item if your not going to make your own. There are available for big and small blocks.
