Factory Maintenance and Component Servicing

This service publication provides the exact documentation dealership technicians rely on for the Eiger 400 platform. It covers everything from engine top-end rebuilds to bottom-end teardowns and transmission disassembly. You will find clear parameters for chassis component inspections and electrical system diagnostics. Following standard service intervals for critical fluids, drive system lubrication, and valve clearance adjustments is essential for machine longevity. Always observe standard shop safety practices and use the correct hoist points when lifting the ATV to prevent equipment damage or personal injury. The documentation references the exact special tools required for complex technical operations, taking the guesswork completely out of the job.

Engine and Chassis Specifications

Precise torque values and clearances are detailed throughout the manual to ensure accurate reassembly. For example, the cylinder head bolts require 26 Nm of torque during engine assembly, while the final drive bevel gear nut needs a full 100 Nm. Intake valve clearances for the 376 cc engine are strictly set at 0.05–0.10 mm when cold. Fluid capacities are clearly charted: expect to use 3.2 liters of engine oil for a complete change with a filter, and 300 ml of differential gear oil. Beyond basic maintenance, the book includes extensive tables outlining internal wear limits, piston diameters, connecting rod deflection, and gear tooth clearances to help you accurately verify component viability during a deep rebuild.
