I took an old injector and welded the rod and "hammer" from one of those "puller" tools to it to pull em out.

Now there's the face of a happy chap!

Have you seen this for the pre-chamber tools?

http://www.peachparts.com/Wikka/OM617PreChamberTools

Also more fuel? I assume you equate more fuel with more power? That could be, under certain circumstances, but I think you are more likely to produce more soot! The first thing I would do is check your timing:-

Good luck!

Start by getting the factory service manual for your car/engine. Easy to find on CD.

What Injector did you use?

On the 617 Engines the Prechembar is threaded for m22X1.0 and as is the Prechamber Puller.

A 617 Injector is threaded on the out side for M24x2.0 so that is way too big.
If you take apart the Injector the threaded area on the upper body where the Nut screws onto is M22x1.5. So the 22mm is correct but the 1.5 pitch of the threads is not.

If he follows your instructions he could damage the threads inside of his Prechamber.

"All tools worked exceptionally well and some of the ideas came off this site from previous threads, however I was not able to find pics (that does not mean they are not there). The entire job after the tools were made took roughly 4 hours and went very smoothly. The only hitch was with the collars, 2 of them came out easily with the homemade tool, the remaining 3 had to be loosened with a hammer and chisel because the collar started to break apart using the tool. During assembly the tool worked like a charm.
Feel free to PM me if any additional details are needed."

The Socket to remove the Prechamber rings needs something to lock it into the Ring so it does not pop up.
The homemade Ring Remal Tool Worked Exceptionally well only on removal ov 2 of the Rings. After that the Tool Failed.
He tells you and shows you the results with; in the first Pic.

In the other 2 pics of homemade Prechamber Tools both tools are made so that they have a screw that locks them into the prechamber Ring and will not jump out of the Slot in the Prechamber Retaining Ring.

Leave the Prechambers in the Head. Clean the surface and see if the head needs to be resurfaced.
If it does not need to be resurfaced there is not much need to remove the Prechambers.

If the Pistons cannot be reused the cost of the rebuild shoots up. The same with the Exhaust Valves.

Sorry I've never used this thread - I assumed it was OK as it was officially approved (i.e. on the wiki) - if you're being really picky I did ask if he had seen it and I didn't specifically recommend it!

When I looked at the cost of the special tools for this job - even at Dutch labour rates - it worked out cheaper to pay someone to remove and reinstall the pre-chambers as part of a machining job. (As you know) The pre-chambers need to be removed in order to skim the head.

I'll have to look to see what I used to make the prechamber puller. I was thinking it was an old injector but it may not be.

Well here is what is odd. It depends on what Engine you have and if it has the Angled Prechambers (that uses the Splined Prechamber Collars).
In the Angle Injection Prechambers the Injectors screw into the Prechamber. This means that you could use an old Injector to make the tool from. Those prechambers have 22mmx1.5 Threads inside of them for the Prechamber Puller.

If you have a 617 the inside of the prechambers is threaded different and is 22mmx1.0. So there is no part of the Injector that will fit them.

In the pic of the Factory made Prechamber Puller you can see the 2 different threaded ends.

If you have a 635,616, or 617 Engine you use the end or the Prechamber Puller that is 22mmx1.0; if you have the Angle Injection Prechambers you use the 22mmx1.5 end of the puller.

The bit You need to remove the head is called a xzn? or triple square. I think it is a 12mm. They do not seem to be an in stock item at most box stores.

they are on the shelf at orilies and autozone in a 4 bit pack.
you do not want torx or spline bits, you want TRIPPLE SQUARE/XZN and I'm pretty sure it's 12mm too.
