of industrial or field use. Drain the filter at each oil change to prevent the old oil contained in the filter from mixing with and contaminating
the new oil. Replace the element at each 8000 miles of highway use or 200 hours of industrial or field use.
AIR CLEANER.
Care of the air cleaner is EXTREMELY IMPORTANT – especially when the vehicle is used under dusty conditions. Clean and refill the air
cleaner reservoir to the level mark, with oil of the same grade used in the engine, at etch engine oil change. When the vehicle is used for field
work, clean and change the oil in the cleaner DAILY and under dusty conditions TWICE DAILY. When cleaning, use a long screw driver or
other suitable tool to dislodge dirt sticking to the bottom and sides of the intake passage in the body of the cleaner.
STEERING GEAR.
Check the level of the lubricant in the steering gear housing every 1000 miles. Avoid the use of cup grease, graphite, white lead or heavy
solidified oil. Remove the plug in the steering gear housing and use a hand gun to fill the housing slowly.
WATER PUMP – CLUTCH.
The water pump and clutch release bearings are prelubricated at assembly and the lubricant lasts for the life of the bearings.
GENERATOR.
Two oilers are provided, one at each end; three to five drops of engine oil is recommended every 1000 miles. Be sure to slip the commutator
end hole cover back in place.
STARTING MOTOR.
The oil hole cover on the commutator (front) end slips to one side; put three to five drops of engine oil in this hole every 1000 miles. Be sure
to slip cover back in place.
IGNITION DISTIBUTOR.
The oiler on the distributor should be lubricated every 1000 miles with several drops of engine oil, Fig. 7, No. 6. Also place one drop of light
engine oil on the wick, No. 2 located in the top of the shaft, which is accessible by removing the rotor arm and sparingly apply soft grease on
the breaker arm cam No. 4, and a drop of oil on the breaker arm pivot, No. 3. See PROPOER MAINTENANCE for Fig. 7.
SPEEDOMETER AND DRIVE.
Some of the speedometers supplied are equipped with a wick type oiler located on the drive shaft boss directly above the tube and shaft
connection to the speedometer head. Lubricate this oiler with a few drops of light oil twice each year. Remove the drive shaft from the tube
once each year, clean it thoroughly and lubricate with a good quality light graphite grease.
UNIVERSAL JOINTS (PROPELLER SHAFT).
Every 1000 miles lubricate the propeller shaft universal joints and the slip joints with a good quality lubricant. Lubricate daily for field work.
UNIVERSAL JOINTS (FRONT AXLE SHAFT).
The front axle universal joints are enclosed in the steering knuckle housings, which are filled with lubricant so require no attention other than
checking each 1000 miles to be sure the housings are filled to plug level. Once each year or every 300 hours of field work the axle shafts and
universal joint assemblies should be removed, thoroughly cleaned and the housings filled with new lubricant.
WHEEL BEARINGS.
Front wheel bearings should be removed, thoroughly cleaned, checked and replaced twice yearly or every 6000 miles. The rear wheel
bearings are equipped with hydraulic lubricators. Lubricate them sparingly to guard against surplus oil saturating the brake lining. An oil
relief hole at the top of housing, Fig. 32, No. 1, indicates when the bearing is filled with oil.
TRANMISSION AND TRANSFER CASE.
Drilled passages are provided between the transmission and transfer case housings for circulation of the lubricating oil to provide unit
lubrication of the two assemblies. The oil level should be checked each 1000 miles or at each lubrication. Drain and refill at each 6000 miles
or 300 hours of field work.
Note: The requirements of these housings are small for economy, therefore, it is very important that the lubrication be changed
every 300 hours when the vehicle is used for dusty field work.
FRONT AND REAR DIFFERENTIALS.
The differential gears require extreme pressure lubricant, which is suitable for hypoid gear type axles. The level of the lubricant in these units
should be checked every 1000 miles. Do not mix different types of hypoid lubricants. Drain and refill the housings each 6000 miles or twice
yearly. Use a light engine or flushing oil to clean out the housings.
Note: Do not use water, steam, kerosene, or gasoline for flushing. If the oil is decomposed, dismantling is necessary.
GOVERNOR.
At each lubrication, check the oil level in the governor housing. Use oil of the same grade used in the engine to maintain the lubricant at filler
plug level. Drain and refill the housing at each 300 hours of operation.
POWER TAKE-OFF SHAFT AND PULLEY DRIVE HOUSINGS.
Check the lubricant level at each lubrication job, maintaining the lubricant at filler plug level. Should the power take-off be used frequently,
change the lubricant each 300 hours.
