🔧 Product Description
Heat-treated starter ring gear used on selected TAD7 engine flywheels. The gear has the tooth form and interference-fit diameter required for the matching starter pinion.
🚤 Compatibility
Typically suits:
- Volvo Penta TAD720VE
- Volvo Penta TAD721VE
- Engine Family: TAD
⚙️ Key Features
- Correct tooth count, pitch and outside diameter
- Heat-treated ring-gear teeth
- Interference fit to the matching flywheel
- Designed for the specified starter pinion
- Concentric installation is essential
🔌 Function
Provides the toothed engagement surface used by the starter motor to rotate the engine during cranking.
⚠️ Common Signs of Failure
- Chipped or heavily burred teeth
- Starter grinding or intermittent engagement
- Ring gear loose on the flywheel
- Localised tooth wear at stopping positions
- Cracks or heat damage from incorrect installation
🛠️ Service Notes
- Fits only the TAD720VE and TAD721VE 7.15-litre industrial engines — this ring gear is not shared with Volvo's larger TAD ranges, so check the engine designation before ordering
- It is the current number in a supersession chain running back through 21033328, 20706915 and 20405650, so a flywheel built at any point in that history takes this ring
- Check the flywheel register is clean and heat the ring evenly before fitting so it goes on to size without cracking — an interference-fit ring dropped on cold will not seat concentric
