Valve Removal Question

I want to do some work on my head while I have my engine apart (valve seals, port and polish) but the valve cotters are proving difficult to remove like they are really tight or something. I watched a video on youtube and the guy did it with some ease. Is there some trick to removing them? Thanks for the help!

 

once you get the "washer "on top of the springs pushed down a magnet should get the split collars out easily. do you have a valve spring compressor?

 

I do not have a valve spring compressor; The guy in the video used a socket and one of those magnet on a stick things. It was a different bike but it ahd pretty much the same design. I guess I will be purchasing a valve spring compressor then.

 

you can make one with a big C clamp and a little piece of pvc pipe.
harbor freight has cheap C clamps , then you cut a notch for your magnet in a short piece of pvc that fits the washer. a few layers of rags on the valve face and head and your in business.
helpers come in real handy too.
harbor freight should have the magnet on a stick too

 

I hope you know what you are doing. Enlarging intake port can make you loose power.

 

I have a valve spring compressor tool I bought from XJForever. Send me a PM and we can work something out as far as buying or renting it.

 

Renting 8O

 

If he paid for the shipping both ways and the paypal fee I'd sell it to him and then reimburse him once he returned it in the mail.
There may even be some sort of escrow service to simplify it.

I paid $50 for the tool from chacal, I'd probably let it go for $30

 

How exactly does the 6" clamp work? I have one, but if there is only a notched piece of PVC on the shim side, aren't you just squeezing the valve against the bottom of the clamp?

 

It should work in the same manner as a spring compressor. The pvc will substitute as the compressor attachment. As you slowly crank the clamp the pvc will press down on the washer and compress the springs causing the tabs in the collars to fall from the grooves in the valve stems. The notch is for fishing them out.

i think it takes a bigger clamp, can you get it around the head to push the valve straight in ?

 

I guess I have been dense, don't mock me but unless I am mistaken you would have to remove the shim and bucket first, yes? I have a never worked on this valve spring configuration before. I am learning a little by little, though.
Fwiw the 6" clamp fits fine.

 

that's right cam, shim, bucket, then you see the top of the valve stem and the split collar keepers

 

If he can see the spring seat and retainers, the shim and bucket are already out of the way.

The issue is having access to be able to remove the collets with the spring compressor in the way. Because the valves/springs are down inside the bores the buckets ride in, a cylindrical compressing tool with cut-out sides is required. "Paddle" shaped valve spring compressors can't reach in there.

 

Yup, I figured it out.

 

Yeah, I hadn't removed the shim and bucket yet, that was where I was hung up. Got it figure out now.

 

here's a tool i made to use with a c-clamp. pvc pipe would work just as well.
you don't need slots just holes, one to put your little magnet thru, one to look thru and one to shine a light in
