Installing valve springs.
I've a replacement G80 cylinder head to build up with new valves etc. I've just ordered one of the lever type hairpin valve spring installing tools (018276) for the job. I've never used one of these before... What's the technique for removing and installing the springs using one of these tools, please?

Re: Installing valve springs.
Hi
Never needed to use the designated tool - for removal I used the standard 'G' clamp type which I guess you'll have from your previous restoration, (though the manual indicates pulling up on the coil will work). Installation is pictured in the workshop manual and as a picture is worth a thousand words apparently I'll leave it there.
Regards Mick

Re: Installing valve springs.
Back in the day I used to remove the springs by pulling up on the coils, and replace them by putting them loosely into position and then pushing the prongs into place with a screwdriver.

Re: Installing valve springs.
If you see a picture of the lever tool in use, you should see The springs and all parts above fitted, One spring in place, the lever tool fitted on the other spring. Looks a bit like a spring on a shovel. When the lever tool is depressed, it shovels the spring in. First time I used one I was 16. Very easy to use and I never had a manual. The half moon type tool slow and fiddly.

Re: Installing valve springs.
Half moon hairpin valve spring compressor.
First you need to undo the two long screws. The tool then bolts onto the head via the two small bolts that goes with the tool. Then you screw down the two long adjuster screws to compress the valve springs. Remover collets etc. The valve drops out. Unscrew the two long screws to remove the springs. Re fitting; Place springs in position, screw down the two long screws to compress the springs. Holding the valve in, fit collar and collets, Holding all this in position ( fiddly ) unscrew the two adjusting screws. Then remove the tool. ( If I remember correctly after 60 years of not using the tool ) Much easier to use the lever to shovel the spring in. Having just pulled them out by hand. ( fore finger through each spring coil ) It is possible to replace springs by hand, not easy unless you get the knack.

Re: Installing valve springs.
Thanks for the information... It looks simple enough. Hopefully, I won't fire the collets through the shed roof!!

Re: Installing valve springs.
Thanks Rob.
Your explanations makes sence of the contraption. I will carry on using my hands as long as i have the strength to fit the springs. Just a simple tip i have used, is to put a very small radius (or de burr) the edge of the spring. It slips in a dream.

Andrew Engineering Ltd. They seem to have quite a lot of stuff that's out of stock at the club spares. I've just ordered some valve collets from them that the club no longer have.Chris Berry wrote:hi pharisee where did you get the tool from.
