Michel's Council (Magickart): Watch the "no screws"!
"It is one of the most sought after parts in the lower engine. My expert advice: During each review, thoroughly check the condition of the teeth, especially on the small part (13D). If the teeth begin to round or become sharp, change the pinion immediately. A break here, and it's the overheated engine in less than a lap.
The indispensables with your pinion 28/13 :
Intermediate pinion axis: Check that the axis is not marked or blued by the heater.
Calibration rings: Respect scrupulously the order of the washers at the winding to avoid excessive lateral friction.
19D drive sprocket: As they work together, if one is worn out, the other often is. Change them in pairs for maximum reliability.
A little pro secret: A pinion in perfect condition is also a quieter engine and less vibration in the lower engine. At Magickart, we don't laugh with cooling!"
