View Full Version : SR valve spring removal ?'s

I just finally started getting around to tearing down my redtop head for inpection and rebuild.
Does the SR require a specific valve spring compressor? I rented one at the local autozone, http://www1.autozone.com/servlet/UiBroker?ForwardPage=/az/in_our_stores/loan_a_tool/valvetrain_repair/valve_compressor.jsp and its not working out.
I have some pics of the problems i'm having but imagestation is down for the moment, so i'll try to make sense in words until i can upload them.

alright, as you can see w/ the pic of the compressor, its cheap.

the first problem, when i get the hooks around the spring and compress it, part of the tool compresses down on to the cam journal limiting the compression of the spring.

second, although not having the spring compressed enough, the way the tool is designed also doesnt allow me to access the valve spring collet and retainer, pretty much making the disassembling impossible.

Thus making me suspect a special/unique compressor is needed, as illustrated in the FSM (KV10109210)

Any thoughts/solutions?

Thanks!

Do you have access to an arbor press? I made a tool to remove the locks on my KA24DE head, it looked like this:

The angled side with the cutout presses on the retainer; the cutout allows you access to fish the locks out. You use a press (not a hydraulic press) to push down on the top, and the head has to be sitting on something so it doesn't just push the valve down (there has to be something underneath to stop the valve).

Made it in about 5 minutes with a bandsaw and a piece of scrap brass http://forums.freshalloy.com/images/graemlins/smile.gif

This is the one we use and it is awesome. once the spring is compressed we use a magnet wand to pull the retainer clips out. It is a snap with this tool. Haven't used it on an SR but several v-tec heads.

i'm in the same boat..........the universal compressors are obviously not universal http://forums.freshalloy.com/images/graemlins/rolleyes1.gif

anyways i'm going to carquest tomorrow to order a "real" valve spring compressor. it should look similar to this :

ahhh rookies.

you need this.

Nesco Valve spring compressor (http://www.etoolcart.com/browseproducts/Valve-Spring-Compressor---NM5112.html)

the best valve spring compressor for our applicaiton. you bolt it to the top of the head where the cam caps used to bolt on then it uses a lever off a bar to compress the spring.

drill a hole or two in your workbench and bolt the head down to the bench so you can get good leverage on it. also put a rag underneath the head in each combustion chamber to keep the valves from moving when you try to compress them. now the spring will compress but the valve wont move...and the keepers will pop loose!

rookie....that you are my friend.....this is the best tool by far. You take springs in and out in seconds, pressureize the cylinder, hit it once to get them out, and then just push the keeper back in. I have done so many honda valve springs with the head on its sick, takes like thrity minuites to do all 16 valve springs on a honda.

We (enthalpy and I) have done it both ways, he just illustrated how to do it with the head off of the motor, as this one already is.

yeah but when you buy it from Snap on, it costs more, even though Nesco makes it.

doing mine this week.
I'm NOT going to remove the head, screw that crap.
I thought about just using 550 cord (military multi purpose rope) and pushing it down into the cylinder through the spark plug hole, then rotating the cylinder up so the string sitting on top of the piston pushes up on the valve. Then using whatever spring compressor to remove the spring, replace with new spring.
Any other ideas? (besides compressed air which I don't have the tools to do)

I have the one bluebomber pointed out, I just need to get some time to put cams in. As for doing it on the car its alot easier filling the cylinder up with air. You can get the adapter for around $8.

Like the other dude said. I have the Snap-On unit and it rocks. I have used it on all kinds of Honda heads and such where nothing else works without any problems.
