How does a Keeper Tool work?


Scott

Recommended Posts

I'm replacing the springs & retainers in my spare head with BC items. I got everything out absolutely no bother but I'm having a bit of bother getting them back in (2 in an hour :blink:)

 

I've managed to find the tool that Ian recommended and have ordered it. However, I can't for the life of me see how it works. The following image isn't the exact same one but it is a very similar design and it would appear the OP used it to create the how to on MKIV.com.

How does the tool manage to get the keepers in without fouling on the top of the valve stem? All I can imagine is the tip of the tool hitting the top of the stem and not allowing the spring, retainer and keepers to move down.

 

Any insight would be greatly appreciated :)

I 'think' the idea is that the outer white parts pushed the retainer down and the inner pointy bit is magnetic allowing the collets to stick to it. As you allow the spring to come back up the collets get trapped between the retainer and the stem as they should but allowing the centre section to carry on being removed.

As you push the outer white part down, the centre part will push the valve down though. Unless the centre part is spring loaded?

Yes, that's about it, it's spring loaded, but be careful, the little devils called collets will leap out sometimes, either into an obscure corner of the garage, or, if ALL the oil drains and holes down into the sump of the engine aren't blocked with tissue, Sod's Law states one will go down there.... :( The tool looks like it can't work, but it does. You need to turn to OD down on Snap On ones, otherwise they'll mark up the tappet bores in the head. Get some spare collets... :)

The head is on the bench so no need to worry about losing bits thankfully.

 

Is the centre part spring loaded Chris? I can't see how the retainer will be moved down without pushing the valve down as well.

Yes, spring loaded, have a look at my answer mate.... If I had a web cam I could demo mine, it'll all become clear once you have the tool in your hand, as the bishop said to the actress ;)

 

Oops lol. There's me pulling up Martin for not reading too. No idea how I missed that but at least I know the script now.

 

Cheers Chris :)

Chris its chaos, the dyno hole we had to dig has killed us, the floor was concrete reinforced with steel, some of it an inch thick, we poured the floor friday and will do the sides monday, we can drop the dyno in the floor tuesday or wednesday. I'll catch you later in the week as i get a bit stressed with all the mess etc and with the plant going we cant hear the phone anyway, same numbers dude.

Horrible things, why cant you use a proper spring compressor???

 

Yes, I was wondering why you need to use this gadget, if the head is off the car? A proper spring compressor is what you need. Probably cheaper than the Snap On gizmo, as well.

 

 

I did look into those but had no idea which ones to get. There are so many variations that I decided the tried and trusted method would be just fine. Also means that I can do the job on the car in the future should I have the need.

 

Are the spring compressors suitable for the 2JZ the C-Clamps?

I use a facom one looks like a big G clamp but screws down rather than clamps.

I had to buy a new valve spring compressor as my old one wouldn't fit. The one below is almost the same as mine and it works perfect.
