Engines with manual transmitting usually have much flywheel, typically 5 to 40 kg of cast iron, with the starter band equipment shrunk onto the exterior.
That is done by heating the ring to around 200 °C to expand the ring which is then rapidly positioned onto the flywheel, often held in firmly against a location shoulder until planetary gearbox coolin in calm air . The interference suit between ring equipment inside dia. and flywheel, usually ranging from 0.20mm to 0.50mm, renders the starter ring firmly mounted on the flywheel.
1. Heating must be done as uniform as possible rather than with a gas burner, as this process causes great temperature distinctions to the pieces.
2. the temperature should be 200°C. A temperature higher than 350°C will affect the apparatus tooth hardness.
3. Do not utilize compressed atmosphere or coolant to cool off the ring.
4. A precise centering and flattening of the parts in the flywheel is an absolutely essential condition.
5. The initial center distance must be maintained.
6. Chilly power press system should be avoided due to a substantial tension triggered to the hardened area.
Engines with automatic transmissions instead have a pressed metal plate with the starter band gear usually welded onto the outside of the plate.
