~ 6N21(A)L ATTACHED SERVICE MANUAL for the ENGINE AIR STARTERS YANMAR SERVICE NETWORKS INSPECTION INSTRUCTIONS FOR MODEL 45MA AIR STARTER CONTROL MODULE 1. Before Inspection Be sure to release the air pressure of the system before setting about the inspection. When the starting power voltage of the air starter 45MA is 24VDC, refer to Fig.1.below. When the voltage is lOOVDC refer to Fig.2. Control Module for 24VDC: Part Number 2-24775-005/ Yanmar Part No. 146673-77191 Control Module for 100VDC: Part Number 2-24775-005-1/Yanmar Part No.146673-77211 2. Inspection. 2-1. Trouble: The air starter does not start even with the application of the normal air pressure. Measure: It is possible that no power is supplied to the control module. Remove the screws at the input and output connectors (see Fig.2 below) and pull them out from the control module body. Check that the power voltage is supplied to the input side connector lead wire. 2-2. Trouble: Solenoid valve does not open even when the power is supplied to the control module. Measure: CD Check the control module body: Impress the power voltage to the plus (+) and minus (-) poles of the input terminal and measure the voltage of the output terminal. The function is normal when the power voltage as impressed appears. @ Check the solenoid valve: Supply O.2MPa (2kg/cm2) air pressure to the NC (normal closed) piping of the solenoid valve removed from the control module. Impress DC12V between the terminals (no polarity) of the solenoid valve, open it and check for the function. If the solenoid valve is normal, replace the control module. @ When the function of the solenoid valve is not normal: YANMAA CO.,LTD. 2006. 2. 13R Remove the elbow, loosen two nuts of the solenoid valve, turn the coil housing (with sealed in black resin) counterclockwise for loosening and remove it from the (aluminum) valve body. Loosen the three screws and check that the valve port is not clogged with impurities. If it is clogged, clean the port and check the function of the valve again according to the instruction of ~ above.

Apply LOCKTIGHT (screw bonding agent) to the threads. @ Lube oil is sealed in the sealing type bearing and the starter drive. Do not wash these items. @ Feed 80g specialized grease inside the reduction gear for lubrication. For O-rings and other items, use AEROSHELL #6 or equivalent gease. The air motor can be disassembled largely into the drive housing (81), gear box housing (66), ring gear (49), contained ring (18) and inlet housing (5). Mark alignment marks on each part before disassembly. TDI TURBOSTART 1WOThl From TECH DEVELOPMENT 66 THREADED INLET CONNECTION P8 AN9139008 Figure 8.
