Light grain being vacuumed into
GrainVac body chamber plug-
ging and stopping the rotary
drum screen
Refer to the Section 4.8. Grain Vacuum Operation Pro-
cedure on page 39 for air throttle adjustment instruc-
tions.
Auger has stopped and the
shear pin has snapped.
Foreign object has entered the
machine and lodged in the
auger.
Clean out the GrainVac body, remove the foreign
object, and replace the shear pin (refer to Section
5.4.1. on page 52). Inspect the auger flighting for dam-
age. Repair or replace the auger flighting if required
(refer to Section 6.2. on page 74).
Gearbox drive chain is broken Clean out the GrainVac body and remove any foreign
objects. Inspect the auger flighting for damage. Repair
or replace the auger flighting if required (refer to Sec-
tion 6.2. on page 74).
Replace with a new chain and oil the chain (refer to
Section 5.4.6. on page 60).
Auger flighting is bent back
impeding grain flow up the
auger
Check all the auger flighting for bent auger tips and
repair or replace the flighting (refer to Section 6.2. on
page 74).
Foam rubber seals in the auger
joints are damaged or out of
place, causing the air seal to be
breached and air to suction
back down auger
Ensure foam or rubber seals between auger tubes are
in good condition and in place (see Figure 4.5).
Breaking shear pin many times
due to malfunctioning or seized
gearbox
Remove the chain coupler that attaches gearbox to
bottom auger along with the main drive chain that
comes from the power shaft (see Figure 5.13) to see if
the gearbox turns freely. Replace gearbox if necessary
(refer to Section 5.4.16. on page 69).
Breaking shear pin many times

Small foreign object is obstruct-
ing an orifice in hydraulic sys-
tem
Ensure hoses are pushed properly into tractor.
Check for damaged hose tips and damaged tractor

Clean out objects potentially lodged in orifice restric-
tions in hydraulic fittings at: male tips, lower lift cylin-
der, control valve.
Check tractor flow controls.
