Folks,
Thought I'd document the starter Oring replacement I just performed on my JetCat P60. I'm not sure how other models are but I do know this is how I replaced mine. Feel free to add any comments or hints and tips YOU may have. I'm sure this is not the "last word".

The pictures will follow along from left to right.

I gathered a 2mm hex wrench, thick CA (cyano for our English friends), debonder, a few cotton swabs, a small screwdriver, and a modified 2 1/2mm hex wrench. I cut off the short arm pretty close to the bend. You'll see why......

Remove the 3 cowl screws with the 2mm wrench being careful not to lose the star washers. Slide the cowl off the turbine housing.
Remove the 2 starter housing screws with the modified 2 1/2mm wrench. The data buss socket covers one screw as shown. Be careful not to damage the turbine housing by banging the wrench into it.
