Hey Fellas,
This weekend I found time to go thru my new (to me) 028 Super. It cleaned up pretty nice for the most part. I discovered that the oil pump had a bad leak and had thoroughly oiled down the area inside of the plastic cover that houses the clutch and brake mechanism. What a mess!
So...I pulled the pump and found that the plastic plug that fits in the aft end of the housing was loose and worn. I was able to get a new one from my local dealer and also picked up the seal for the input shaft. Those parts went in pretty easily, and then I used two cans of Brake / Parts cleaner to clean all the oil out of the clutch and brake assembly.
When I had the muffler off I took a look at the piston and am not sure if what I'm seeing is "normal" wear and scratches, or if I'm dealing with a badly scored piston. I took a picture, it's not the best, but hopefully can see what I'm talking about. Also here's a couple pictures of the cleaned up saw put back together.
It seems to run quite nicely, I just wonder if the condition of the piston is going to be a power robber and should be replaced. I didn't put my compression tester on it yet, but plan to do so and will report back with the results.
Thanks for any opinions you guys might have!
