July / August 2015 15 Here you can see the rod sliding through the hole and through the bottom of the cylinders and into the #6 piston. Once the wrist pin is seated firmly, remove the tool. My hands are small enough that I can slide into the # 5 cylinder from the top and with my finger through the hole into the #6 cylinder verify the wrist pin is seated fully. Now comes the tricky part; inserting the wrist pin clip. The idea here is to be slow and methodical setting up the insertion, and then drive the clip home with force. If you miss, the tension of the wrist pin clip will pop out of the piston/tube and end up in the cylinder case. Then you take out how ever many pistons you have installed on bank two, disassemble the case halves, fish it out, and reassemble and try again. Not fun and very time consuming. To insert the clip, it is installed on the inside of the black tube from the tool kit (show in the first picture). Then use the rod that was used to insert the wrist pin to slide the clip out of the tube and into the side of the piston. The clips are very strong and they hold themselves in the tube easily due to pressure so don't worry about it falling out. Here is an idea of how the tube needs to butt up against the piston to allow for clip insertion. If there is any gap at all, the clip will not seat and will end up in the engine. The clips are under such tension, that if you have ever removed a wrist pin clip from a piston with a small screwdriver, you know how easy it is to shoot it across the shop if you don't catch it. Here is the tube inserted into the engine, and butted up against the piston. Now comes the tricky part. … ENGINE ANATOMY: M96/M97 PART 2
