ring gear

Engines with manual transmission usually have much flywheel, typically 5 to 40 kg of cast iron, with the starter ring gear 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 shoulder until coolin in calm air . The interference suit between ring equipment 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 ought to be 200°C. A temperature higher than 350°C will affect the apparatus tooth hardness.

3. Do not utilize compressed surroundings or coolant to cool down the ring.

4. An accurate planetary gearbox centering and flattening of the items in the flywheel is an absolutely essential condition.

5. The original center distance should be maintained.

6. Chilly power press system ought to be avoided due to a substantial stress caused to the hardened area.

Engines with automated transmissions instead have a pressed metal plate with the starter ring equipment usually welded onto the outside of the plate.
