Yanmar ViO15-2 Common Problems This Manual Covers
Yanmar ViO15-2 rubber crawler tracks pop off the idler or show excessive undercarriage wear
Inspect the undercarriage and measure the rubber crawler tension clearance as shown on page 157. Adjust the grease cylinder until the clearance is exactly 0.31 to 0.51 in. (8 to 13 mm). Torque the nipple valve to 36.1 ft·lbf (49 N·m) to secure the tension setting.
Manual Section: Procedures for Maintenance p. 157Engine cranks but will not start or stumbles heavily due to water contamination in the fuel system
Drain the fuel system and clean the water separator element, which is required every 50 hours per the schedule on page 150. Check the main fuel filter and replace it if you exceed the 400-hour service interval. Bleed all air from the fuel lines before attempting to restart.
Manual Section: Maintenance Table p. 150Boom and bucket controls feel slow or hydraulic pump whines under load during heavy digging
Verify the system relief set pressure reaches 2986 PSI. Replace the hydraulic oil tank return filter element as detailed on page 190 if fluid is contaminated. Reinstall the filter housing and tighten the flange bolts to a torque of 50.6 to 65.1 ft·lbf (68.6 to 88.2 N·m).
Manual Section: Procedures for Maintenance p. 190Coolant temperature alarm sounds during operation and engine runs excessively hot under normal load
Clean the radiator fins and inspect the air cleaner element. Blow out dirt from the inner filter using compressed air at less than 100 PSI (0.7 MPa) as directed on page 182. Replace the air cleaner element completely if the machine has reached the 400-hour service mark.
