(2) 8 x12 Rotax Carter Pion

Full description: what is the purpose of this piece?

Even if we do not see it more once the engine is closed, this pawn fills critical functions:

1. Geometric alignment: It deletes the "game" between the mounting screws and the holes of the housing. It guarantees that the left crankcase and the right housing form a perfectly symmetrical set.

2. Bearings protection: By perfectly aligning both sides, it avoids that the crankshaft does not work "through". A bad alignment, even a tenth of a millimeter, would heat up and destroy your bearings in record time.

3. Sealing the seal plane: By preventing any lateral sliding from the housings at the time of clamping, it ensures that the seal (paper or paste) is uniformly crushed, thus avoiding the air intakes or oil leaks.

4. Precision machining: Made of hardened steel, it does not deform under pressure and allows successive disassemblies / invalid up without losing its accuracy.

💡 Michel's trick

"It's the piece we forget once on two on the workplace! Listen well: if you go back your low motor and you have a pawn of 8x12 in your rail box, you restart immediately. Without these pawns, your engine will never be aligned, and you will ask you why you lose power or why your bearings grow. My little tip: before closing, checks that they are sorry for their accommodation. And if a pawn is marked or flattened because it has been pinched, throw it and put in a new one, it costs anything three times! "

🎓 TUTO: assembly and precautions

1. Location: The pawns are generally placed at the two opposite ends of the housings (often near the cylinder studs or at the bottom of the block).

2. Cleaning: Make sure the reception wells in the aluminum housings are perfectly clean. A small filled in the bottom can prevent the pawn from going down and create a fatal extra thickness.

3. Insertion: The pawn must enter fat in the first crankcase. If it force too, do not type as a deaf: clean the hole with gasoline.

4. Assembly: Present the second half-crankcase. The pawns must guide the assembly. Once the housings are attached, they should no longer be able to slide from each other before even put the screws.
