the other to vent trapped air while lubricating.
17. There is no scheduled interval for performing an engine tune up. As long as the engine performance is
satisfactory, no tune-up) should be needed. Major adjustments in the valve and injector operating mechanisms,
governor, etc., should only be required periodically to compensate for normal wear on parts.
For detailed
information, refer to the engine operator's manual.
18. Lubricate clutch release bearing after each 50-hours of operation using special lubricant as listed in lubricant
recommendation. Engine should be running during lubrication. Do not overlubricate. Check for pedal clearance
at this time and lubricate linkage. Check master cylinder fluid level.
If inspection indicates clutch pedal "free travel" is less than 1/2-inch, immediate adjustment of the linkage should be made
to restore the approximate 1 1/2-inch measurement. This adjustment is made on the clutch cross-shaft lever itself and not
on the slave cylinder adjusting rod. Desired dimensions are shown on the following illustrations.
