MAINTENANCE 4.11 EVERY 500 OPERATING HOURS OR MONTHLY 4.11.2 FLEXIBLE DRIVE COUPLINGS - CHECK OIL LEVEL See illustration Z 20703 NOTICE The Engines must be out of operation for approximately 30 minutes before checking the oil level. This period is nec- essary for settling of the oil in the lower part of the coupling housing. 1. Remove guard (1). 2. Turn flexible coupling by using barring device (2) to bring oil level gauge (3) in its uppermost (12 o’clock) position. REMARK To use the barring device, remove the clip and push the device shaft toward the flywheel. The barring device must be rotated counterclockwise to turn the flywheel (flexible coupling) in the direction of normal rotation. 3.
Unscrew gauge (3), wipe it clean and insert into the gauge opening. DO NOT screw in. Pull out gauge (3) and read the oil level. 4. If necessary add oil through gauge opening to bring the oil level up to the ”MAX” mark on gauge (3). To speed-up the fill- ing procedure, remove bleeder screw (4) and warm up the oil to approximately +30 ° C. 5. Insert gauge (3) with packing ring and bleeder screw (4) with packing ring and tighten securely. 6. Check area (A) for leakage. If oil leakage is found (radial traces of oil), O-rings (5) must be checked for damage and replaced if necessary. 7. Install guard (1). 8. Repeat checking procedure on the flexible coupling of the second engine. 357
