Part of the New Holland Repair Manuals.
This is New Holland service manual 47711684, 1st edition, May 2014.
It covers the L218 and L220 200 Series skid steers, Tier 4B (final): the L218 from PIN NEM476231 and above, and the L220 from PIN NEM475087 and above. It includes hydrostatic pump and drive motor tests, chain case and axle work, the loader valve, high flow, self-leveling and ride control. It also has wiring for mechanical and electro-hydraulic machines, plus UCM and engine fault codes.
The specifications give the charge, main and circuit relief pressures, pump flows and fill capacities to test against, and troubleshooting tables cover the hydrostatic pump and loader self-leveling.
