Section 4: Maintenance & Lubrication
Maintenance
General
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly down time and repair.
Read and obey all safety labels on the Skid Steer Auger.
Securely block raised equipment before working under or
around it. Do not allow anyone to operate or perform
maintenance on this implement who has not been
properly trained in its safe operation. Do not alter the
equipment in a way which will adversely affect its
performance or reliability, or for a purpose the product is
not designed.
!
DANGER
Keep all persons away from rotating auger. Contact with
rotating parts can cause serious injury or death. Keep all
shields in place and secure when operating.
!
WARNING
Stop engine, engage parking brake, raise seat bar, move
controls until both are locked and remove key to prevent
unauthorized starting before performing maintenance on the
auger. Use steps, grab-handles and skid-resistant surfaces
when getting on or off the loader.
!
WARNING
Always secure Skid Steer Auger with solid supports before
servicing. Never work under equipment supported by
hydraulics. Hydraulics can drop equipment if controls are
actuated or if hydraulic lines burst. Either situation can drop
the auger instantly even when power is shut off.
!
WARNING
Keep all hardware properly torqued tight. Loose components
and hardware can break sending flying pieces in the direction
of the operator and others that may be close-by.
Daily Inspections
1.
Inspect auger point and teeth for wear and loose fit.
Keep cutting edges sharp. Sharp cutting edges dig
easier and better.
2.
Inspect flighting for wear, bend and cracks.
3.
Inspect auger mounting hardware for wear, bend and
loose fit.
4.
Inspect all connecting pins and hardware for wear,
bend and loose fit.
5.
Inspect out put shaft for bend and wear.
6.
Inspect drive chain and sprockets for wear and
proper tension. See instructions for “Drive Chain
Inspection & Take-Up” on this page.
7.
Replace worn, damaged or illegible safety labels by
obtaining new labels from your Land Pride Dealer.
Drive Chain Inspection & Take-Up
Refer to Figure 4-1:
1.
Remove front cover (#3) by unbolting 5/16" hex head
cap screws (#4).
2.
Inspect drive chain (#9) for wear and chain tension.
Tighten chain as follows:
a. Remove rear cover (#1) by unbolting 5/16" hex
head cap screws (#4).
b. Loosen 1/2" hex had cap screws (#5) four places
and pull motor mounting plate (#2) back until
chain slack is removed. Do not over tension.
c. Do not under tighten chain take-up bolts (#5).
See “Additional Torque Values” on page 22 for
chain take-up bolt torque value. Hold mounting
plate (#2) in its new location and retighten chain
take-up bolts (#5) to the correct torque.
d. Attach rear cover with four 5/16"-18 x 3/4" Gr5 hex
head cap screws (#4) and lockwashers (#6).
e. Attach front cover with four 5/16"-18 x 3/4" Gr5
hex head cap screws (#4), lockwashers (#6) and
flat washers (#7).
f. Tighten cap screws to the correct torque.
Roller Chain Take-Up

IMPORTANT: Do not over tension drive chain. A
tight chain will overload auger shaft, motor shaft and
associated bearings. Damage to components due to
an over tensioned drive chain will void its warranty.
IMPORTANT: It is extremely important to tighten
chain take-up bolts (#5) to their full torque to prevent
plate movement under auger load.
