REPLACING A WORN AUGER SCREW BIT.
Application: All augers.
Tools Required:
1 each, suitable safety glasses.
1 each, hammer
1 each, 1/4 inch diameter, straight-type punch.
Parts Required:
1 each, PN P302 Screw Bit (3 inch diameter auger).
1 each, PN P801 Screw Bit (2 inch and 4 to 8 inch
diameter augers).
1 each, PN 20041200 Roll Pin (2 and 3 inch diameter
augers, if required).
1 each, PN 20051800 Roll Pin (4 to 8 inch diameter
augers, if required).
The screw bit utilized with the 2 and 3 inch diameter
augers functions as the boring head. No other blade is
utilized.
1) The replacement of the auger screw bit will require a
level working platform of sufficient size and appropriate
height. Wear safety eye wear and any other apparel
deemed appropriate for the job application and/or job
site environment.
WEAR SAFETY EYEWEAR AND ANY OTHER
SAFETY APPAREL DEEMED APPROPRIATE
FOR THE JOB APPLICATION AND/OR JOB
SITE ENVIRONMENT. THE TOOTH
REPLACEMENT PROCESS CAN CREATE
FLYING STEEL CHIPS AND/OR OTHER
DEBRIS. CAUTION ALL ONLOOKERS
REGARDING THE POSSIBILITY OF AND/OR TO
REMAIN CLEAR OF FLYING DEBRIS.
IMPROPER SAFETY PROCEDURES CAN
RESULT IN PROPERTY DAMAGE AND/OR
PERSONAL INJURY.
2) Inspect the auger for worn or broken components.
Check to determine that the auger does not have a
bent or damaged axle. A bent or damaged axle will
cause the auger to "wobble" during use. Maximum
allowable auger wobble is 0.25 inch (7 mm) total
indicated runout (TIR). An auger with a total indicated
runout wobble in excess of this value should be
removed from service and scrapped.
DO NOT OPERATE AN AUGER WHICH HAS A
BENT OR DAMAGED AXLE WITH A TOTAL
INDIC ATED RU N OU T EXCEED I N G T H E
MAXIMUM ALLOWABLE LIMIT. EXCESSIVE
AUGER WOBBLE CAN REDUCE OPERATOR
CONTROL, RE S ULTI N G I N PRO PERT Y
DAMAGE AND/OR PERSONAL INJURY.
3) Using the hammer and drift-type punch, remove the
roll pin from the auger axle.
4) Remove the worn screw bit from the auger axle.
Align the hole of the replacement screw bit with the
hole drilled in the auger axle.
5) Install the roll pin with the hammer and straight-type
punch.
6) Return the auger back to service.
REPLACING A WORN AUGER BLADE.
Application: All augers 4 inch diameter and larger.
Tools Required:
1 each, suitable safety glasses.
2 each, 7/16 inch wrenches.
Parts Required:
1 each, PN E244, 4 inch diameter auger.
1 each, PN E246, 6 inch diameter auger.
1each, PN E248, 8 inch diameter auger.
Required Quantity: 2425 bolt, washer and nut.
Blades are hot-coined from alloy steel and heat treated
to extend their service life. All blades utilize 1/4 inch
diameter capscrews, lock washers and standard nuts
to retain the blade to the auger plate. Each blade
incorporates a minimum of two capscrews. An auger
that has only one capscrew still visible and/or usable is
worn beyond its useful service life and should be
discarded.
1) The replacement of the auger blade will require a
level working platform of sufficient size and appropriate
height. Wear safety eyewear and any other safety
apparel deemed appropriate for the job application
and/or job site environment.
