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 …

SHOCK ABSORBER NEEDLE VALVE SHORTENED

To lessen any possibility of the needle valve protruding too far from the wing shaft and rubbing against the brake rods when turning a sharp corner, the shock absorber needle cable assembly A-18037-A has been shortened approximately 1/16” (See Fig. 1169). The new valve can be installed in old shock absorbers.

Shock Absorber

Figure 1096 shows the working action of the shock absorber when the lever arm is moving on an upward stroke. When driving over a rough road, the recoil of the car springs is instantly softened by the resistance set up in the shock absorber in forcing the fluid in the shock absorber through small by-passes. …

Disassembling Shock Absorbers

Remove shock absorber from car. Place instrument in clamp and tighten the wing nut. (See Fig 1101). Remove filler plug. With the reservoir lock ring wrench, turn the cover lock ring 1⁄4 turn to the left, to relieve ring tension. (See Fig. 1102). To remove reservoir cover, place the reservoir cover wrench in the position …

CHANGE IN SHOCK ABSORBER NEEDLE VALVE

Shock absorber needle valve stem A-18037-A (above the thread) has been increased 1/16” in diameter and the head of the valve stem changed from a square to a hex head. Increasing the thickness of the stem, strengthens needle valve and lessens any possibility of twisting.

NEW SHOCK ABSORBER FLUID

We are purchasing a quantity of shock absorber fluid which will be known as M-564 Ford hydraulic shock absorber fluid. This will be available for dealers in the near future. As soon as this fluid is available, it should be used in all Ford shock absorbers instead of the glycerine and alcohol mixture. Under no …

Correction

Due to a typographical error it was stated on page 302 in the December Bulletin that the Front Shock Absorber adjustment for cold weather was made by screwing the needle valve in until it seats, then backing the valve off 3/8 of a turn. This should have read 5/8 of a turn. From letters received …

Adjusting Shock Absorbers

((573)) The pointer on the shock absorber needle valve has been removed and the end of the valve slotted so that it can be easily turned with a screw driver. (See Fig 573) The numerals which were stamped on the shock absorber arm have also been removed as they are no longer required. Slotting the …

Shock Absorbers

Ford hydraulic double acting shock absorb­ers operate entirely on the principle of hydraulic resistance. Glycerine is forced from one cham­ber to another by the movement of the lever arm. The working chamber is automatically kept full by the glycerine in the reservoir. As the shock absorbers are accurately ad­justed at the factory, it should not …
