Easier tool for blind install of wrist pin clips M96

If you've ever rebuilt an M96 engine ,you'll know how tricky it is to instal the wrist pin clips for 4,5,6. There are plenty of videos showing a glorified broom-handle tool and what looks like a slide hammer. Yes, it is a tedious,slow process even with the correct & expensive Baum tool. The tool needs mods. to work - if you don't index and mark the tool ,it is even more likely the clip will 'misfire'. You'll need to dismantle the engine to retrieve the wire circlip if you are lucky ! If you don't notice ,you'll have engine failure on start-up.Got your attention? So my question is : "WHY USE An oem wrist pin CLIP ?" Instead, use a spirolock/Spiralock/spiro-lock with a blind insertion tool+extension ??The Baum tool could be modified to use the tool shown in the linked video? This isn't a new idea ,so I am surprised others have not discussed this option. Watch this -He even sounds like Jake!

Funny you posted this.. The Raby Faultless Wrist pin tool (patent pending) debuts in just a couple of days... Twist and install OEM clips without using any Porsche tool. These are available to pro builders through SSF Auto Parts, but I am sure that Pelican will nab them up and sell them to enthusiasts too. The tool was designed to omit the points were all mistakes are made with the factory tool. The unique aspect about this tool is it allows simultaneous wrist pin, and wrist pin retaining clip installation to occur, for a one step procedure. The issue with the spiral lock and tool in this video is the real estate that you have to work with inside the M96 engine, on bank 2. The other issue is that you have to work 100% blind deep within the engine, and you can't see the "tails" of the spiral lock to ensure they are installed correctly. I have tried to do this with an M96 and there were way too many compromises. I've been working on these tools for a long time, I even have one design that uses a small powder charge from a Hilti nailer to literally fire the clip into place. With the patent process its all about covering every base that anyone could ever think of to offer some latest and greatest tool, that probably won't even work. Here's a sneak peek of the Faultless wrist pin and clip installation tool. The first order to SSF ships out on 1.5.14 Excuse the photo, its from an iPhone. I let the other people worry about selling them, my job is done... After two years!

Congratulations on the new tool ! Too late for my build but I guess I'll have the medals for persevering with the current Baum tool.I think you helped develop that too- many years ago? I am glad someone other than me thinks about improving M96 tools. I was beginning to think I had a unique M96 fixation :-). The other guy who offered a wristpin/circlip tool was Logray - his stuck tool removal hook -is on Renntech. The Lock-in-Tool guys live near you I think. Sadly they are going out of business and selling all their tools/machines. Lock-In-Tool 2511 Providence Rd.

Anyone else got M96 tool ideas to share?

I spoke too soon.Jake's tool is not too late for my build! The clumsy Baum tool and my fumbling cracked off the oil-control piston-ring land. Sadly,I now know exactly how to modify the Baum B9602K piston pin driver kit so it does not destroy pistons !It is an easy mod but I am sure Jake's tool is a better solution. https://rennlist.com/forums/boxster-...lp-please.html

I received mine yesterday.. Once I get my track car ready for the season, I'll go ahead and assemble my 996 motor.

I'm assuming this was done with only a grey or brown charge?

Where did you get the tool and what was price?

I got a pre-production one. LN should have them available soon.

Actually, thats a production unit... It was just used when I wrote the instruction manual. SSF Import Auto parts (wholesale distributor) has the exclusive on these for one year. They have a pallet of them on the way now. SSF sells to shops, so it will be a while before some of these get into the hands of retailers. Pelican is likely to get them first, from a re- sell perspective. Now that they've all shipped, and the instructions are done, after 3 years, my part is done.... Now on to the next tool development!

Hello all. I am assembling my 964 engine and struggled initially with installing the wrist pin circlips. I proceeded to make a simple tool that proved to work flawlessly spending 5 cents on materials and 5 minutes of my time. I would like to share this with fellow engine assemblers instead of forking out ridiculous $ on the so-called circlip installation tools some of these companies charging nearly $ 2000.- for this tool. Absurd. Here is a pic of my simple tool. A piece of PVC water pipe, a cut out to negotiate the edge of the cylinder sleeve and grinding a 45 degree angle at the end so the tube sits hard against the piston wrist pin opening. The diameter of the wrist pin opening is 12.95 mm. So grind the 14 mm pvc tube and with a 45 degree angle so it slots inside the 12.95 mm piston diameter. Then use a deep socket that matches the ID of the pvc pipe. Press the circlip with a flat head screw driver into the tube, then I insert your deep socket, press the 45 degree tube side hard against the piston 12.95 opening, tap the deep socket with a hammer and voila! Done.

I probably just ruined the tool supply market for wrist pin circlip installation. Of course you can have this machined in metal cheaply if you wish. But as a diy person how often do you use this tool anyway…..

Great design ! Thanks for sharing. >it will be interesting to read the experiences of others who try this in future.

I did the same thing a few years ago. Cost of $0 😆 You Tube

964 is very very different from 996/997 in process. There are some brave souls out there with DIY 996/997 solutions but the rest of us make do with a fairly expensive sir-tool set up which we have to modify a bit.
