SECTION 6
OIL, FILTER AND LUBRICATION INFORMATION
Do not use regular oil or grease to lubricate the idler chains.
Regular oil or grease will be thrown off the idler chains dur-
ing normal operation, and contaminate the brake pads or
discs. When these components become contaminated, brake
efficiency is affected.
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-lubri-
cate 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
CAUTION
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 manu-
factured, it requires re-greasing only every 100 hours of op-
eration or before the vehicle is taken out of service for any
extended period. Use a pistol grip type grease gun to avoid
dislocating the bearing seals due to excessive grease pres-
sure.
CAUTION
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 nip-
ples. These bearings should be greased with a small amount
of Shell Alvania No. 2 grease or equivalent at 250 hours of
operation or whenever major maintenance is performed on
the vehicle. The grease fittings become more accessible when
the idler chains are removed.
Figure 6-9 Idler shaft bearing grease nipples
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 Shell Alvania
No. 2 grease or equivalent every 250 hours or before the
vehicle is taken out of service for any extended period. Only
a small amount of grease is required.
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 Shell Alvania No. 2 grease or equivalent frequently, at
least every 25 hours of operation, to flush dirt and water that
may have entered the axle seal. Only a small amount of
pressure should be required. Grease until any contamina-
tion has been forced out past the seal and fresh grease is
visible.
At the same time, inspect all the axle seals for damage (Fig-
ure 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.
