WESTFIELD - GRAIN AUGERS 7. TROUBLESHOOTING
MK 100/130 PLUS X 91’ - 111’
30260 R0 61
Shear bolts
fail repeatedly.
Incorrect shear bolt type.
Replace with correct part number. Westfield
shear bolts are specifically designed to provide
correct driveline protection.
Shear bolt hole worn out-of-
round.
Frequent use of an incorrect shear bolt size can
wear the mounting hole creating a “scissor
effect,” which will require replacement of the
affected parts.
Corn spreaders in bin unable to
keep up with auger output.
Slow down auger or remove corn spreaders.
Flighting “peeled back” as a
result of plugging.
Occurs when bin has overfilled or corn spread-
ers restrict end of discharge. Inspect flighting at
discharge end. If necessary, replace flighting.
Driveline failures (bearing, gear-
box, etc.).
Refer to appropriate troubleshooting section.
Lower bear-
ings repeat-
edly fail.
Bearings not receiving adequate
grease.
See Maintenance section for correct greasing
intervals.
Bearing load not evenly distrib-
uted between upper and lower
bearings.
Use correct sequence of tightening lock collars
when setting up or replacing bearings. On
MK130 Plus models, adjust bearing load using
threaded upper flight stub.
Insufficient CV PTO shaft clear-
ance.
Maintain correct tractor hitch dimensions as per
manual.
Failure of bearing seals.
Wet grain or fertilizer will damage seals if left in
boot over time. Clean out boot before storing
auger.
Bent lower flight stub.
Check for straightness of flight stub by rolling
across flat concrete section. Straighten stub or
replace as necessary.
Premature
wear on auger
tubes.
Auger being at low capacity or
empty for extended periods of
time.
Frequently occurs on farms using grain wagons.
Auger should no be left unattended when filling
bins. Depending on application, a belt conveyor
may be more appropriate.
Bent flighting. Refer to appropriate troubleshooting section.
Flighting allowed to wear
beyond normal point of replace-
ment.
When flighting becomes razor-thin at intake,
replacement is critical. Since flight material is
double thickness at welded lap joints, high spots
on flight occur and can accelerate spot tube
wear.
Hydraulic lift
settles out
over time.
Shut off ball valve is open.
Oil is leaking through tractor calve. Auger ball
valve should be closed whenever set up at a
bin.
Shut off ball valve is leaking.
Disconnect hose from tractor and check for
leakage.
Lift cylinder cup seal leaking or
cylinder barrel scored or pitted.
See if oil leaks from cylinder breather hole (sin-
gle action cylinders). Remove and replace cup
seal and hone cylinder or replace as needed.
