Engines with manual tranny usually have much flywheel, typically 5 to 40 kg of cast iron, with the starter band equipment shrunk onto the exterior.
This is done by heating the ring to around 200 °C to expand the ring which is then rapidly placed onto the flywheel, often held in firmly against a spot planetary gearbox shoulder until coolin in calm air . The interference match between ring gear inside dia. and flywheel, usually which range from 0.20mm to 0.50mm, renders the starter ring firmly attached to the flywheel.
1. Heating must be completed as uniform as possible rather than with a gas burner, as this process causes great temperature variations to the pieces.
2. the temperature should be 200°C. A temperature greater than 350°C will affect the apparatus tooth hardness.
3. Do not utilize compressed surroundings or coolant to cool off the ring.
4. An accurate centering and flattening of the parts in the flywheel is an absolutely essential condition.
5. The original center distance must be maintained.
6. Cold power press system ought to be avoided because of to a substantial stress caused to the hardened area.
Engines with automated transmissions instead possess a pressed steel plate with the starter ring equipment usually welded onto the outside of the plate.
