Changing valve springs without lifting head....   2014-01-28 18:10:00 <Hunt M> Hey all. While my diff is out and I'm waiting for parts to arrive, I thought I'd put the set of heavier valve springs in that I have. Is the rope down the spark plug hole trick the best way to go about keeping the valves seated without removing the head? I've heard bad things about using compressed air and if there's a slight leak Etc the valve may fall down? Any tips or tricks to doing it? Cheers Hunt (html version)

Re: Changing valve springs without lifting head....   2014-01-28 18:44:00 <Tom Hill> Just did the stem seals on my 2j. Rope worked a treat. One cylinder at a time. Feeding the rope in is a bit shit. Be careful not to scratch the bores for the buckets or they won't go back in so easy. The collets fit down the oil drains so make sure you rag everything up.

Re: Changing valve springs without lifting head....   2014-01-28 18:51:00 <Tom Hill> I put a screwdriver in the spark plug whole of the cylinder that is in the same position as the one I was working on. So you can get an idea on what's going on. Make sure you get enough rope in there too. The valves need to be restricted enough as to not move or else getting your springs compressed back into place will be a pita.

Re: Changing valve springs without lifting head....   2014-01-28 19:27:00 <Hunt M> Thanks for that. So I'm guessing you lower the piston you're working on, add rope, bring piston back up as much as you can? How close to bottle dead centre did you start feeding the rope in? Yeah I imagine losing the keepers down the oil galleries would be a rather large pain in the *ahem*....

Re: Changing valve springs without lifting head....   2014-01-28 20:33:00 <Tom> Yeah lower it down as much as you can. Fill er up with a decent amount of rope, i got > a meter of 8mm nylon rope in there. Dont feed the whole rope in though haha. Turn it till it seizes on the rope. But not so much to bend anything though lol.

Re: Changing valve springs without lifting head....   2014-01-29 19:15:00 <Hunt M> What was the tool like that you used to compress the springs? I was thinking of welding an old screw driver to a thick washer - but not sure if that's the best way to do it?

Re: Changing valve springs without lifting head....   2014-02-04 12:14:00 <Tom Hill> I just used a good sized socket on an extension with a mallet to take them out, and used an actual keeper removal tool to press them back in. looked something like this: http://www.powersportrider.co.za/prodimages/engine%20tools%20valve%20spring%20collet%20remove.jpg Having a strong magnet is also super handy to pull out your buckets as well as catch your keepers.
