Complete description: a high precision axis

Although it is only a "simple" steel cylinder, its role is strategic:

1. Surface rectification: Its surface is perfectly smooth to limit friction with the bore of the pinion. This allows fluid rotation, even at high speed.

2. Alignment of the waterfall: It keeps the intermediate pinion perfectly parallel to the crankshaft and pendulum gables. A twisted or marked pawn, and it's all the gnat that works through.

3. Tempered steel: Designed not to mark under the pressure of gear teeth, ensuring that no "game" settles with time.

4. Adjusted mounting: Extract precisely in the housings Rotax (Land 11 on the technical bursts), ensuring the total stability of the gear train.

💡 Michel's trick

"It's the axis that carries all the mashed intermediate sandy! My advice: Whenever you opened your crankcase, go out the pawn and look at its surface. If you see bluish marks (heating) or stripes you feel under the nail, change it Direct. A marked axis, it's a pinion that will end up getting through and eating his teeth. And a small stuff of old mechanic: to the reassembly, put a drop of XPS oil on the axle before sliding the pinion on it, it avoids it works to Dry the first seconds!"

🎓 Tuto: assembly and verification

1. Carter inspection: Check that the receiving hole in the aluminum of the housing is not oval. The pawn must enter "fat" but without lateral game.

2. Setting up: Insert the pin thoroughly into the engine crankcase. It must be perfectly perpendicular to the seal plan.

3. Pinion installation: Slide the intermediate sprocket on the pawn. Check that it turns freely, without hard point.

4. Lubrication: Beginning with spinning lubricated, make sure the box of box oil is correct so that the axis is always well watered.
