SECTION 6
OIL, FILTER AND LUBRICATION INFORMATION
After every 100 hours of operation, remove both idler chains
from the vehicle and clean them thoroughly in a suitable
solvent. Allow the idler chains to dry thoroughly, re-lubricate
them generously with Argo chain lube and re-install. Refer to
section 7.2.5 of this manual for idler chain removal and re-
installation instructions.
6.4.5 Outer Axle Flange & Bearing Lubrication
DO NOT USE HIGH PRESSURE
PNEUMATIC GREASING EQUIPMENT
Each outer axle flange is equipped with two grease nipples.
Grease the outer cavity through the outer nipple of each flange
with a lithium based, NLGI #2 or 3 mineral oil based grease,
(such as Shell Alvania #3). Apply at every 25 hours of opera-
tion, to flush dirt and water that may have entered the axle
seal. Only a small amount of pressure should be required.
Grease until any contamination has been forced out past the
seal and fresh grease is visible.
At the same time, inspect all the axle seals for damage (Figure
6-8). Vegetation wrapping around the axles can damage the
rubber lip of the seal, allowing dirt and water into the outer
cavity. Replace any damaged seals.
Figure 6-8. Outer Axle Flange
The second or inner grease fitting of the outer axle flange
supplies grease directly to the outer axle bearing. Since the
bearing is well sealed and packed with grease when manufac-
tured, it requires re-greasing only every 100 hours of opera-
tion or before the vehicle is taken out of service for any ex-
tended period. Use a pistol grip type grease gun to avoid
dislocating the bearing seals due to excessive grease pres-
sure.
Do not use high pressure or excessive amounts of grease.
Damage to the bearing seals could result.
6.4.6 Idler Shaft Bearing Lubrication - All Models
The idler shaft bearing flanges are fitted with grease nipples.
These bearings should be greased with a small amount of a
lithium based, NLGI #2 or 3 mineral oil based grease, (such as
Shell Alvania #3). Apply every 100 hours of operation or when-
ever major maintenance is performed on the vehicle. The
grease fittings become more accessible when the idler chains
are removed. Alternatively, ARGO Part# 658-16 Right Angle
Coupler, can be used to access these fittings (also sold at
automotive supply stores as a Right Angle Grease Coupler,
Thexton part no. 418).

6.4.7 Inner Axle Bearing Lubrication
The inner axle flanges are equipped with a grease nipple.
Lubricate the bearings with a small amount of a lithium based,
NLGI #2 or 3 mineral oil based grease, (such as Shell Alvania
#3). Apply every 100 hours or before the vehicle is taken out
of service for any extended period. Only a small amount of
grease is required.
