Oil Grooves in Main Bearings
After rebabbitting a cylinder block be sure to form oil grooves in the main bearings. (See Fig. 1226.) K. R. Wilson furnishes a tool for this purpose.
Lubrication
LUBRICATING SHOCK ABSORBERS
When lubricating shock absorber connecting links, the pressure gun should be held on the lubricator fitting until lubricant escapes from both the top and bottom of the link. (See Fig. 1183.) Some mechanics are failing to do this, as a result the upper ball joint does not receive lubrication and results in premature wear and …
NEW LUBRICANT FOR FRONT WHEEL BEARINGS
A new short fiber sodium soap grease having a high melting point is now being used in production in all front wheel bearings. This front wheel bearing lubricant has been carefully checked and tested under severe operating conditions and has proved unusually efficient. Under no circumstances should it be removed from new cars and other …
LOWERED OIL CONSUMPTION
Several improvements have recently been made in Model A engines which tends to still further lessen oil consumption. A shield is now provided which fits around the oil pump and insures a more uniform distribution of oil to all cylinders. The oil pan tray has also been lowered 1⁄8”· This has been accomplished by correspondingly …
ADDITIONAL LUBRICATOR FITTINGS
Until recently we were using oilless bushings in a percentage of our water pump cover assemblies. We are now using a plain bushing and a roller bearing in all water pump covers. The adoption of the plain bushing and roller bearings for 100% production, necessitated placing lubricator fittings in all water pump cover assemblies (see …
ADDITIONAL LUBRICATOR FITTING PLACED ON TRUCK TORQUE TUBE
To insure truck universal joints receiving ample lubrication, an extra boss has been placed in the torque tube to accommodate an additional lubricator fitting which is installed just back of the universal joint ball cap. This fitting permits the lubricant to flow directly to the joint without first passing through the bearing. Any stock of …

NEW BREATHER PIPE
To lessen any possibility of oil working past the breather pipe, breather pipe A-6763 has been adopted (see Fig. 896). The baffles in the new pipe point down- ward and towards the center of the pipe. This directs the oil away from the edge of the pipe and lessens any possibility of oil working past …
BEARING CAP OIL PIPE CHANGED
The size of the crankshaft rear bearing cap oil pipe has been changed from 5/16”to 3⁄8” (see Fig. 864). Increasing the size of the oil pipe allows the oil to drain more quickly from the main bearing into the oil pan tray especially in cold weather.
LONGER LUBRICATOR FITTING
A longer lubricator fitting AA-24408 is now used in the truck clutch release bearing (see Fig. 848). The new fitting replaces the A-24405 fitting which was a trifle too short to conveniently use with the standard grease gun furnished in the tool kit.
OIL PUMP SPRING
Before installing an oil pan or clean out plate in one of the earlier Model A cars or AA trucks, be sure to replace the oil pump retaining spring. This is very important. If the spring’ were omitted, it would allow the oil pump to drop down far enough to become disconnected from the oil …
If Starting Motor, Windshield Wiper or Horn Fails to Operate or Generator Fails to Charge
In cold weather lubricating oil sometimes congeals and hardens on the commutators in the above parts, causing a coating of insulation between the commutator bars and the brushes. Under these conditions the 6-volt current supply is of too low tension to force current through this coating of ‘insulation and consequently the part fails to operate. …
LUBRICATOR FITTING ON STEERING GEAR CHANGED TO A PLUG
To eliminate the possibility of mechanics putting grease instead of gear lubricant in the steering gear, the Zerk fitting has been replaced with a pipe plug (see Fig. 776). Never put grease in the steering gear. Complaints of hard steering can invariably be traced to that source. Use gear lubricant only in the steering gear-the …
