We have the fulcrum style that we use on the bench occassionally. But by far, the best/easier one looks like a medium sized metal flashlight. It has a magnetic tip, and you simple push. I dont have the PN or brand handy, but any tool truck should carry one. Jeremy should have one of these two types...ask him what he uses.

When I did my VQ30 heads I used a fulcrum style, the first few were a PIA. One of the things I did to protect the lifter bores in the head was, I took two old lifters and cut the tops off, then and deburred the cut real good. Then slid them in the lifter bore. This way if I slipped with the compressor I wouldnt srcatch the bore.

i made one out of aluminum bar stock. it hooks under the cam saddle bolt, then a washer welded onto a couple stand-offs that compress the spring at the correct fulcrum point. polished the edges smooth on the washer to keep from scratching the bore.
sounds complex, but it took about 10-15 minutes to make and had the parts to make it laying around, lol.
can send a pic if you really want.

these are good for removing the locks, but are not the easiest for installing them.

The Nissan one is a KV10115900 which is a KV # I believe ( KV is a company that has been making Service tools for yrs for special applications) I think that # is Nissan J26336-20
But I have always fabed my own ---There is the Falcrum which is handy for removal of the springs on a pressurized installed head or any # of universal C-clamp types for bench work.
BTW....Off subject, but on reinstallation of the keepers always make sure you have the same spacing on both sides of the half moon so one does not touch the other. Just a little thing, and one in a thousand, but have seen a time or two that at High RPMs, the keepers being spit out due to interfereance

I went ahead and ordered the snap-on piece that Sharif was recommending........
in the mean time, I removed apair of the exhaust valves using my own technique......
place a 17mm socket on the retainer. use a 6" extension on the socket....... give it a solid whack on the end of the extension with a mallet.......the result is that the keepers pop right out!
