WP13 Diesel Engine Series Operating Manual Figure 5-18 Replace the Water Collector. Check the intake system, as shown in Figure 5-19. ● Check whether the air intake hose is aging or cracked and whether the hoop becomes loose. When necessary, tighten or replace relevant parts to ensure sealing performance of the intake system. Intake manifold Figure 5-19 Check the air filter element.
WP13 Diesel Engine Series Operating Manual The diesel engine allows the maximum intake resistance of 7kPa, which shall be checked when the diesel engine is working at the rated speed and full load, and when the intake resistance reaches the maximum allowable limit, the filter element should be cleaned or replaced according to the provisions of the manufacturer.
30000km(400h) Routine maintenance Therein, for WG Class-II, contact Weichai Power Maintenance Service Center for National-III Landking Engines once every 10000 kilometers’ (200 hours’) working. A- First mandatory maintenance: replace the engine oil and oil filter, but do not replace the fuel strainer and fine filter elements.
Chapter VI Analysis and Troubleshooting of the Common Troubles The WP13 series diesel engines are designed and manufactured in a strict quality assurance system, and each diesel engine has been tested as specified. At the same time, the diesel engine is a kind of precision machinery, with its long-term effect closely related to normal maintenance and services.
(1) The starter does not work The WP13 series diesel engines have their starters controlled by ECU, in time of normal work, the ECU will output a current to drive the starting relay, and after the relay is connected, the battery will drive the starter to start the engine.

WP13 Diesel Engine Series Operating Manual (4) The crankshaft and camshaft signals are missing On the diesel engine, there are two speed sensors mounted respectively outside the flywheel housing and the high-pressure fuel pump. The functions are respectively shown as follows: the crankshaft position sensor and cylinder identification sensor will decide the fuel injection timing of electronic control engine, and if a diesel engine cannot be started, such two signals have been missing.
