How to remove valve springs without a valve spring compressor!

I found this video on Youtube and I gave it a try since I don't have a valve spring compressor and after going to 20 different places I still can't find one.
It is very simple and uses 2 basic tools and a magnet. I didn't have one like the one in the video so I stole one from the fridge and I put a cloth between the retainers and the socket to avoid damaging them. Worked perfectly and only took me 5 minutes.

you can do it even quicker by replacing the magnet with an extention in the socket, and putting a rag under the valve, and just hit the extension/socket with a dead blow hammer and they will fall out.

i have a really slick tool that is just like a big socket that has a magnetic ring around it and its designed to be hit with a dead blow hammer. when you hit it the keepers get sucked out to the magnet, and the retainer and spring will pull out with it (if they are steel of course).

just watch your eyes, if a keeper gets stuck halfway it could shout out at any moment. i usually wear glasses or keep my face far out of the line of fire until i know they are totally seated or removed.

That's good to know, I might try it your way next time because keeping the magnet in place was a bit tricky for me.

True but the reason I didn't use one is because for it to get here I need to wait around 2-3 weeks and I couldn't not find a small enough one locally.

i have valve spring compressors, but i didnt want to buy one JUST so i could do the heads on quads, so i just cut a socket to look like cataways pic and use a large c-clamp.

the fancy tool i have for removing keepers also has an insert for pushing the keepers in, but i found the valve springs on performance quads are MUCH stronger than most diesels or auto engines. i used it once on my Z head and my hand was bruised from pushing so hard to compress the springs.

The right tools mean a lot when you consider how easy it is to put a ding in the bearing jornal for one of the cams, or scar one of the bores that the tappets run in. The right tools can realistically mean not blowing an engine or ruining a head.

Lisle valve keeper removal/installer tool. 30 bucks. Haven't tried it on a motorcycle head, but it works great on Honda car cylinder heads. Super quick, use it with a 2lb deadblow.

Save on Lisle 36200 at ToolTopia.com

Here's a vid which was "related" to the OP video. I personally wouldn't risk slipping with needlenose pliers and taking out a cam journal.

I removed them like the video said but had the keepers installed at the Kawi dealer for free. It saved me one trip.

I'm not a mechanic by trade but I learned a long time ago to use the right tool for the job!!! Some GREAT home made tools may be fine and some are not! Don't take the chance, it can cost you much more when something goes wrong. It usually takes more time also. My theory is if you have ANY project ahead of you and you are going to save say,$300 doing it yourself, spend the $50 to buy the tool and do it right. If it's something you may only use a few times, buy a cheap one, not a snap on. I didn't even watch the video, the hammer was enough for me to think no way.
