valve spring removal

[andym]

I had a look for removing valve springs without special tools and came across this video:

Has anyone else actually tried this?

You still fucking about with that fucked bike? Count your losses, brake it and make some cash back But keep the CDI and get this

2nd attempt to sell and reduced by 100 quid. Get a cheeky offer in.

[andym]

The only problem with that is I don't have any money left now otherwise I would and just bin the other one.

As for the video, turns out a socket, molegrips and a magnet work perfectly for removing and refitting

[Marmalade]

Yes. It does work. use the rag or everything slips and the collets fly off into the grass.

So I hear

A valve spring compressor costs about 5 quid. Seriously.
You need one to put them back in anyway (if you want to do it properly and minimalise valve dropping risk).

I see no point in this method, and either way, using a sliding t bar with the socket on the end and a bit of bodyweight works better, and won't make everything fly out.

What can I say, I'm a cheap f**ker.

Anyway, I found the socket with a magnet through the centre and a pair of molegrips works fine for removing them without bits flying off into the sunset.

For putting them back on, I just used a pair of pliers to push the spring back down and the collets fall into place.

I just need to get the valve grinder and paste then I can work on the old head

[pits]

I can see that it does work, but am I the only one who thinks that hammers shouldn't really be used on the inside of an engine?
Dead Blow to pop pistons out fine
Lump hammer to twat a starter motor
Nylon hammer to tap the head loose.

But a ballpin and a socket to remove valves, I just feel that it will one day end with disastrous consequences

Nothing wrong with that method - I've never see it done any other way. You've more chance of firing a collet into oblivion if you use the compressor IMO.

I sit the head on a thick layer of rags (usually a rolled-up lumberjack fleece) to prevent any valve damage and pop them all out in a couple of minutes with a hammer and spark plug socket.

you will need

an old socket with a quarter of it cut out,
a G clamp
small screwdriver or probe

open the G clamp and place flat side to the valve, place the socket on top and compress the spring, slide collets out with screwdriver, remove tension then clamp and socket slide the spings off and if required the valve out

OK if I could edit MP4's I'd have edited out all the crap, but a couple of videos I've just done for removing and refitting valve springs:

Removing: (Note the lack of hammer) https://www.youtube.com/watch?v=9Ph3Y9cEDUU

Fitting: (needle nosed pliers just to position the collet) https://www.youtube.com/watch?v=t_8hpMjLma0

Nothing lost, nothing flying around, nothing getting it's brains bashed in.... and more importantly, no buying special tools or adapting tools

Whats stopping the valve moving with the top of the spring? If its on a table, it seems a good way to bend a valve stem

You stick a rag under the valve head. This method has been used for donkey's years.
