D400E Series II Ejector Truck Caterpillar

It may be necessary to check the alignment of the ejector blade. Refer to Operation and Maintenance Manual, "Ejector Blade Alignment - Check /Adjust".

Cutting Edge Adjustment

The cutting edges for the ejector blade should be checked periodically in order to ensure that the clearances are correct. If the ejector blade has been removed and replaced, or if the cutting edges are outside the specified clearances then the cutting edges must be adjusted.

1. Install the steering frame lock before carrying out maintenance in the area of the oscillating hitch. Refer to Operation and Maintenance Manual, "Steering Frame Lock - Install".

2. Start the engine.

3. Extend the ejector blade slowly. Observe the clearance (A) for each of the cutting edges as the ejector blade is extended. Mark the positions of minimum clearance (A) on the body for each of the cutting edges. Measure the clearance (A) at these points. If the clearance (A) is less than 5 mm (0.2 inch) the adjustment of the blade is necessary. If the clearance (A) is greater than 5 mm (0.2 inch) the adjustment of the blade is necessary.

   Note: Clearance (A) may be at a minimum at different points for each cutting edge. The clearance for each cutting edge must be set at the corresponding point of minimum clearance.

4. Move the ejector blade to one of the positions that was marked in step 3 for the side cutting edges (1). Stop the engine and move the battery disconnect switch to the OFF position.

5. Loosen bolts (3) for the cutting edge (1) at the side of the ejector blade.

6. Ensure that the clearance between the cutting edges (1) and the body is 5 mm (0.2 inch). Tighten bolts (3). Use a suitable wedge in order to hold the cutting edge in position while the bolts are tightened.

7. Move the battery disconnect switch to the ON position and start the engine.

8. Repeat step 4 to 7 for the other side cutting edge (1) .

9. Move the ejector blade to one of the positions that was marked in step 3 for the bottom cutting edges (2). Stop the engine and move the battery disconnect switch to the OFF position.

10. Loosen bolts (4) for the cutting edge (2) at the bottom of the ejector blade.

11. Ensure that the clearance between the cutting edges (2) and the body is 5 mm (0.2 inch). Tighten bolts (4). Use a suitable wedge in order to hold the cutting edge in position while the bolts are tightened.

12. Move the battery disconnect switch to the ON position and start the engine.

13. Repeat step 9 to 12 for the other bottom cutting edges (2) .

14. Return the ejector blade to the RETRACT position. Extend the ejector blade fully and monitor the clearance between the side scraper blades and the body.

15. If clearance (A) is below 5 mm (0.2 inch) at any point, repeat steps 3 to 12.

16. Once the ejector blade cutting edges are adjusted, fully retract the ejector blade. Torque bolts (3) to 135 N·m (100 lb ft) and torque bolts (4) to 217 N·m (160 lb ft).

17. Stop the engine.

If the cutting edges are particularly worn it is possible to reverse the cutting edges (2) at the base of the ejector blade. The side cutting edges (1) cannot be reversed.
