Lubrication Information
1000 Miles or 30 Days
Chassis Lubrication
Chassis lubrication is important for long service life and quiet
operation. Factory recommendation was every 1000 miles or 30 days of
operation.
Want to be sure you lube all the fittings ? Use this list as your road
map.
Front Wheel Upper Control Arms
6 fittings, 3 on each side. One for the control arm pin, 1 for front and
1 for rear control arm pivot bar bushing.
Steering Knuckle King Pins
4 fittings, 2 on each side. 1 for upper bushing, 1 for lower bushing.
Lower Control Arms
6 fittings, 3 on each side. 1 for control arm pin, 1 for front and 1 for
rear control arm pivot bar bushings.
Tie Rods
4 fittings, 1 for each ball joint rod end.
Clutch and Brake Pedals
2 fittings, 1 for clutch bushing and 1 for brake bushing.
Clutch Torque Shaft
1 fitting at center of torque shaft.
Gearshift Control Bellcrank
1 fitting.
Total Fittings: 24
Optional Fittings
Water Pump
One fitting, water pump grease only. (Later model replacement pump may
have sealed shafts.)
Propeller Shaft Spline
1 fitting, found front end of rear propeller shaft ( 7 Passenger Only)
Steering Gear Box
Don’t forget to check the steering gear box. Use SAE 90 Gear Lube. If
the seal has failed on the kingman and your lubricant runs out, try
chassis lube until you can replace the seal. It's better then letting
the steering gears run dry.
Crankcase Vent System.
See Techtips article
Air Cleaner
Approximately 1 Quart Motor Oil. ( SAE 50 for 32 degrees and above, SAE
20 for below 32 degrees.)
3 Speed Transmission
Check fluid level.
5,000 mi.
Oil change and new oil filter
10,000 mi. or 1 year
Lubrication Of Rear Wheel Outer Bearings
(Before you perform this maintenance step check our Tech
Tip.)
One lubrication point commonly overlooked is the outer bearings on the
rear axle. Because no zerk fitting is mounted this maintenance step is
usually missed. Behind the brake backing plate is a small bolt tapped
into the side of the axle. Remove this bolt and using your grease gun
shoot approximately 1/2 ounces into the hole. DO NOT over lubricate as
it may force grease past seal on the brake backing plate. Then
re-install the bolt. If re-assembling axle and bearing you may need to
add additional grease before reinstalling bearing.
3 Speed Transmission: Drain and refill,
SAE 90 above average -10 Degrees, SAE 80 for average below -10 degrees.
Generator: 5 to 10 drops in oil cup at
front.
Distributor: 5 to 10 drops in oil cup, 2 -3
drop in oil wick under rotor.
Starter: Oil cup, if used.
Front Wheel Bearing: Inspect, repack and/
or replenish as needed with short fiber wheel bearing grease.
Speedometer: 2 to 3 drops #10 weight engine
oil applied to oil hole on cable.
Windshield Wiper Pivots: Inject a few drops
of light oil
15,000 mi. or 2 years
Rear Axle Differential
Drain and refill, SAE 90 above average -10 Degrees, SAE 80 for
average below -10 degrees.
20,000 mi. or 2 years
Universal Joints
Disassemble, clean and repack with heavy fiber Joint Grease.
Speedometer Cable, re lube.
