Description

Product Overview Master the drivetrain and engine management of your vehicle with this comprehensive Chery QQ6 Service Manual. This file uniquely combines two critical technical documents: the overhaul guide for the QR513 Transmission Case and the service manual for the UMC EFI system (473F Engine).

Whether you are performing a complete QR513 transmission rebuild, diagnosing a “Check Engine” light using the UMC electronic fuel injection fault codes, or simply adjusting the gearshift mechanism, this manual offers the factory-approved procedures you need. It includes detailed exploded views, precise torque specifications, and logic trees for resolving idle speed issues and starting failures.

Key Features:

• Transmission Overhaul: Detailed procedures for the decomposition and assembly of the input/output shafts, differential, and gearshift fork mechanism.

• EFI Diagnostics: In-depth analysis of sensors (Oxygen, Knock, Crankshaft Position) with testing methods and resistance values.

• Troubleshooting: Extensive charts for resolving common failures like “Gear jump,” “Oil leakage,” “Cold starting difficulty,” and “Unsteady idle.”

• Specifications: Complete technical data for gear ratios, clearance adjustments, and sensor parameters.
