24.5.1 BLADE CUTTING EDGE HARDWARE

Check the torque of the blade cutting edge hardware.

U Plow bolt nuts: 455 N*m (335 Ibf ft);

The engine is equipped with an automatic belt tensioner that maintains correct tension on the drive belt. To check belt tension a Burroughs type gauge must be used because of the wide drive belt. Proper tension should be 110 to 150 N (80 to 110 lbs).

If a Burroughs type gauge is not available, tension may be checked by belt deflection. Press the belt with your finger at the longest span and measure the deflection. Maximum deflection 9.5 to 12.7mm (0.37 to 0.50 in).

With the automatic tensioner, adjustment isn't required.

To replace the drive belt, place a 12 in. drive breaker bar (1) in the square hole in the belt tensioner. Push the breaker bar UP to loosen the tensioner. Remove the old belt (2). Inspect belt tensioner. The tensioner pulley should spin freely with no rough spots detected under hand pressure. Install the new belt.

24.4.1 CHECK OIL LEVEL IN DRIVE TRAIN

1. Open the right side door at the hydraulic reservoir.

2. Unscrew the T handle of the oil level gauge, remove the gauge and wipe it clean.

3. Insert the gauge fully into the filler sleeve. Do not tighten. Remove the gauge and check the lubricant level. If necessary, add oil through the filler to bring the level up the FULL mark on the gauge. Reinstall and secure the gauge.

For details of the oil to use, see 20. USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE.

4. Lift up on lock lever and close door.
