Lubrication Service Standards - Wagon

Initial Lubrication

When a new vehicle is placed in service or an engine is overhauled, the engine oil should be changed after the first 500 miles [800 km.} of operation and again after an additional 1500 miles [2.400 km.]. The oil filter should be cleaned and the element replaced after the first 2000 miles [3.200 km.] of operation. As much as 4000 miles (6.400 km.) of operation may be required to properly seat the rings and decrease oil consumption to normal. Under no conditions should an oil heavier than SAE 20W be used during the summer or SAE 10W during the winter for the first 500 miles [800 km.] when an engine is new or has been rebuilt.

Engine Crankcase

The oil in the crankcase should be changed after each 2000 miles (3.200 km.) of normal service. The oil bath air cleaner thoroughly removes all dust from the air before it enters the carburetor. For efficient operation, the cleaner must be serviced at regular intervals. Care of the air cleaner is extremely vital to the life of the engine. Pay particular attention to the amount of dust and dirt in the air taken into the engine through the air cleaner. When dirt is not noticeable in the air, service the air cleaner each 2000 miles [3.200 km.]. Whenever the air is notice­ably dusty (for example when the vehicle is driven on secondary roads or through fields) then service the air cleaner more frequently. Under extreme continually dusty and dirty conditions where the vehicle operates in clouds of dust and dirt, service the air cleaner daily.

To service the air cleaner, unscrew the eye bolt on the oil cup clamp and remove the oil cup. Scrape all dirt from inside the oil cup and clean the inside surface with cleaning solution. Refill with new oil of the same viscosity as is recommended for the engine crankcase to the oil level bead and install the cup securely to the cleaner body with the attaching clamp. Air cleaner body (less oil cup) should be removed from the vehicle and cleaned at weekly intervals or oftener. To do this, loosen hose clamp, and remove hose from the cleaner. Detach breather hose from the fitting on the cleaner. Remove the two wing screws and lift cleaner from vehicle. Agitate the cleaner body thoroughly in cleaning solution to clean the filtering element. Dry element with air hose but do not re-oil.

Speedometer Cable

Remove the speedometer cable from the tube every 12,000 miles [19.200 km.]. Clean it thoroughly and coat it with a good quality light graphite grease.

Hand Brake Control

Lubricate all bearings and clevis pins of the hand brake control each 1000 miles [1.600 km.]. Lubricate the brake cables inside the conduits each 12,000 miles [19.200 km.].

Choke Control

Lubricate the exterior surfaces of the flexible conduit with penetrating oil every 1000 miles [1.600 km.].

Brake Master Cylinder

Check the fluid level in the brake master cylinder every 1000 miles [1.600 km.]. Wipe clean the top of the filler cap and also the housing area around it. Replenish the brake fluid to a level 1/2" [1,3 cm.] below the top of the fill hole. Use only heavy-duty brake fluid conforming to specification SAE-70-R1. Be sure to handle the brake fluid in clean dispensers and containers that will not introduce even the slightest amount of other liquids. Replace and tighten the filler cap.

Clutch Linkage

Lubricate all friction points of the clutch linkage every 1000 miles [1.600 km.]. Use the same grade of engine oil as used for the engine. Failure to lubricate these points will result in premature wear; the links will wear and the holes in the mating parts will become elongated.
