Full description: what is the purpose of this piece?

This pinion is the starting point for the thermal safety of your engine:

1. Mechanical training: It transmits the motor motion with intermediate gears of the water pump. Its size of 19 teeth is calculated precisely to provide optimal fluid flow by engine speed.

2. Cooling synchronization: The more the engine runs, the more the pinion causes the pump quickly, thus adapting the cooling to the force requested to the engine.

3. Original quality Rotax : Made of high-strength technical plastic material, it is designed to withstand the friction and heat of engine oil without deforming or wear out prematurely.

4. Universality: This pinion is compatible with the entire range of engines Rotax 125 Max (Junior, Senior, Master, Evo) as well as the Dd2.

💡 Michel's trick

"Listen to the guys: This plastic pinion is the fuse of your cooling. If you have debris or blocking in your water pump, it is he who will trink to protect the rest. My advice: every time you open your crankcase for a Revision, spend a brush shot on the teeth. If you see that plastic starts to become white or the teeth are marked, change it! It's a cheap piece that can save you a 2000 ball engine!"

🎓 Tuto: assembly and verification

1. Alignment: When mounting on the tree, make sure the pinion is engaged on its grooves or its flat. He must turn without any veil.

2. Visual control: Check the absence of cracks between the teeth. A gable that breaks in full track, it is the temperature needle that is instantaneously.

3. Lubrication: Although bathed in box oil once closed, drop a little oil on the tits to the mounting to avoid dry friction during the first start after revision.

4. Preventive change: Like all plastic workouts, it is recommended to replace it every 50 hours or during each complete bidding of the low engine.
