Check the auger teeth for any wear and for any 

damage. 

Replace worn teeth before any damage occurs 

to the auger bit. Replace worn teeth before any 

damage occurs to the mounting bolt and to the nut. 

Replace any damaged teeth. 

Rotate the auger teeth from the outside of one side 

to the inside of the other side in order to increase 

the life of the auger teeth. 

Note: Ensure that the teeth that are replaced or 

rotated maintain the original cutting angle.

1. Remove bolt (1) in order to remove the damaged 

tooth (2). 

2. Orient the new tooth in the same cutting angle 

as the old tooth. Place the new tooth onto the 

auger bit.

NOTICE 

Care must be taken to ensure that fluids are contained 

during performance of inspection, maintenance, testing, 

adjusting and repair of the product. Be prepared to 

collect the fluid with suitable containers before opening 

any compartment or disassembling any component 

containing fluids. 

Refer to Special Publication, NENG2500, “Caterpillar 

Tools and Shop Products Guide” for tools and supplies 

suitable to collect and contain fluids on Caterpillar 

products. 

Dispose of all fluids according to local regulations and 

mandates. 

Note: Put identification marks on all lines, on all 

hoses, and on all tubes. Plug all lines, all hoses, 

and all tubes. This will help to prevent fluid loss and 

this will help to keep contaminants from entering 

the system. 


1. Block up auger drive (1). 

2. Remove three hydraulic hoses (2). 


3. Remove eight bolts (3), washers and nuts.

4. Slide the planetary (5) forward approximately 

50.8 mm (2.0 inch). 

5. Use a suitable lifting device to remove the 

planetary (5) and the gear motor from the drive 

housing (4). The planetary and gear motor weigh 

86.2 kg (190 lb)


g00653190 

6. Remove both filler plugs (6) from the planetary. 

7. Drain the oil from the planetary into a suitable 

container. 

8. Fill the planetary with oil. Maintain the oil level 

to the bottom of the threads of the filler plugs 

when the holes are horizontal. Refer to Operation 

and Maintenance Manual, “Lubricant Viscosities” 

and refer to Operation and Maintenance Manual, 

“Refill Capacities”. 

9. Apply 5P-3413 Pipe Sealant to each of the filler 

plugs. Install the filler plugs. 

10. Install the planetary and the gear motor into the 

drive housing. 

11. Install the eight bolts, washers, and nuts. 

12. Install the three hoses.

Walk-Around Inspection 

SMCS Code: 6700-040 

i01215791 

NOTICE 

Accumulated grease and oil on a work tool is a fire 

hazard. 

Remove debris with steam cleaning or high pressure 

water at any time a significant quantity of oil is spilled 

on the work tool. 

Note: Watch closely for leaks. Use a board or a 

piece of cardboard when you check for a leak. If a 

leak is observed, find the source of the leak and 

correct the leak. If a leak is suspected or a leak is 

observed, check the fluid levels for the auger and 

for the host machine more frequently.


Inspect the pilot tooth (1) for damage or for 

excessive wear. Replace the pilot tooth, if 

necessary. 

g00649871 

Inspect the auger bit teeth (5) for damage or for 

excessive wear. Replace any damaged teeth or 

any worn teeth. 

Inspect the auger housing (7) for leaks from the 

auger motor. Correct any leaks. 

Inspect the hydraulic system (3) for leaks. Repair 

any hydraulic system leaks. Inspect the hoses, 

the seals, and the flanges. 

Make sure that the planetary (6) is secured to the 

auger housing. Tighten any loose bolts. Replace 

missing bolts. 

Inspect the mounting bolt (2) for the auger bit 

for damage or for wear. Replace the bolt, if 

necessary. 

Inspect the mounting bracket (4) for damage or 

for wear. Refer to Operation and Maintenance 

Manual, “Frame Mounting Bracket - Inspect”.
