Warning:
- Since the gearbox consists of high-precision manufactured parts, these parts must be handled with extreme care during disassembly and assembly to avoid damage.
- A rubber mat should be placed on the workbench. During disassembly, do not use gloves made of fabric or rags. If necessary, use nylon products or paper napkins. Metal parts can be cleaned with regular detergents followed by thorough air drying.
- The clutch disc, pressure plate and rubber parts must be cleaned using automatic transmission fluid.
