Finally made some headway today. Got all 6 squirters out of the case, new ones in, and staked back into case. I figured I would share how I did it, if it can be of any help to others out there. Although I was uncomfortable going at my case with a hand drill, it was actually pretty easy, and not too dangerous if you are not hamfisted about it.
First off, I delicately dremeled off the bulge from the stake into the squirter bore. I went easy, and kept checking with a magnifying glass . Next, I drilled out the top of the squirter with a 5/32" drill bit. Only drill down deep enough to get through the top of the squirter, and get the spring out. I was real careful here , I did not want to hit the spring with the drill bit, and break it off in there. That would be a mess. After you have drilled out the top, fish out the spring, and ball. A few of my balls were still stuck, and took a bunch of air pressure, and coaxing with a wire to get them out. Once you have the spring and ball out, I drilled down the rest of the way through the squirter. I then cleaned out all the chips, and ran a 5x80 tap down through the squirter. I was also careful with the tap, breaking off a drill bit , or tap would be just about the worst thing you could do here. The nozzles are soft alum, and drill easily, and tap easily also.
I then cobbled up a slide hammer with a 5 mm screw. I threaded the slide hammer/screw into the piston squirter bore. I threaded it all the way down , there are not many threads to grab onto, down in the bottom, so you want to make sure you are engaged as far in as you can be.
I then gently heated the case with the mapp gas torch. I watched it with a heat gun, and only went to about 120deg. It was early, and cold in the shop, and the case was only about 50 deg. at this point. A few gentle taps with the slide hammer, and they walked right up out.
At this point, I dressed the top of the bore, and made sure the new squirters would slide right in. I made sure to clean the squirter bore with brake clean, and q tips, and then the case went back to the tank for a good rinse and re clean of all passages . Install was easy peasy. I made a quick install tool out of one of the old squirters, and a long screw. I lightly coated the squirter in locktite 241, making sure there was no excess that could get under the squirter, and gently tapped them down in. Although the new nozzles were the same length, they had more of a chamfer on the bottom, and did not sit down as far. I then used a small chisel to re-stake at the factory spots, and added 3 more new stakes just for good measure. I gave the locktite a few hours to cure, and checked all 6 squirters. All opnened at low pressure, had a nice spray, and no more dripping out of any. Here is what it looked like after I was done
Have everything all layed out and ready, and can now seal up the case in the morning.
