Technical Documentation Scope

When you have a maxi-scooter on the lift, you need exact factory numbers fast. This documentation provides complete baseline data for the T300-LEA7-A2 production build. It outlines all engine, chassis, and electrical system specifications straight from the manufacturer. You get direct access to critical torque values for cylinder head hardware and transmission components, plus exact tolerance charts for valve clearances, piston dimensions, and clutch wear limits. Having this reference reduces guesswork and helps ensure every job aligns with original factory standards.

Service Reference Data

The guide details precise fluid capacities, noting a 1.5-liter engine oil capacity during complete disassembly and a 0.23-liter transmission gear oil requirement. Electrical diagnostics are supported by ECU parameters, such as ignition timing mapping from 10° BTDC at idle up to 33° at 6500 rpm. Working on high-pressure hydraulic, fuel, or electrical systems carries inherent risks. Always consult the specific safety protocols and use appropriate personal protective equipment before applying these specifications to active shop work.
