I just tackled the installation of a new starter on my C-150B. The most challenging part of the process is cutting off the old starter's pinion shaft from inside the case of the engine. If you follow the pictures posted on the Sky-tec website the process is much easier. I cut a piece of cardboard(took a couple of times of fitting and re cutting) and used clay to fill the gaps between it and the case. This worked perfect to keep the broken cut-off wheels and the cutting debris from entering the engine. I fed a drop light between the firewall and engine mount to adequately light up the area. I also stood on 2 step ladders on the left side of the nose and actually worked from above, not from the side. I did make two cuts on the shaft to allow the final cut to be almost flush with the case. The first cut took off about 2 and the final took off the remaining 3/8s of the post. Hold your cutter firmly and squarely so you dont slip off and either nick the case or nick the gear teeth that are right below the shaft. If you have a very thin piece of stainless sheeting, you may want to tape it to the top of the gear and below the shaft before cutting (just in case you slip). I did my final dressing of the stub with a dremel tool flat grinding stone. I then vacuumed out the entire area and flushed the remaining crud out of the area with solvent. I feel that most everything was washed out, which was a concern prior to starting. This took about 4.5 hours for everything(removal of old starter, cable, T handle and firewall bracket, cutting off pinion shaft & cleaning cavity, installation of new starter, wires, push button and reinstalling the cowl). A project like this is very intimidating but is really not that bad. And you talk about spinning the prop...WOW! I should have done this years ago. The weight savings is huge(about 8 pounds)!!

I replaced my Sky-Tec Starter C12ST2, S/N 2C-100702 on my 0-200 Continental engine. My engine tac time is 147 hours since engine Major overhaul and Sky-Tec starter installed. I did not fly my aircraft for several years but none the less the Sky-Tec starter at the most has 400 starts on it. So, I drove to Aircraft Spruce and Specialty in Georgia to pick up a new Sky-Tec C12ST2. I could not believe that for $923.00 you dont even get a Gasket with the starter. Many people may be asking why I purchased another Sky-Tec if the last one failed with only a few hundred starts! After working on aircraft for 40 years. I am betting that I received a defective starter and Sky-Tec will compensate me. (NO GASKET REALLY!)
