12 - 8 FRONT SUSPENSION
NOTE: The pivot pin key seal is lead and is used with the
key that holds the steering arm to the steering spindle. This
key also holds the pivot pin and the lead seal prevents
lubricant being forced down the outside of the pivot pin into
the key way and then outside to cause loss of lubricant.

STEERING PIVOT PIN WEAR
Adjust the front wheel bearings before starting any check
for wear in the pivot pin or bushings. Place one hand on top
of the tire and the other hand on the bottom of the tire and
pull with one hand while pushing with the other to determine
the amount of play between the pivot p in and bushing.
If there is an appreciable amount of movement due to
excessive wear, the bushings should be replaced.
Wear at the spindle pivots is seldom confined to one side.
It is therefore advisable to renew the parts on both sides.
FIGURE 14
This is to relieve excessive grease pressure (500 to 600 lbs.
per square inch) that may be applied at the grease fitting at
the top of the plug. This prevents grease from leaking out
around the expansion plug and any possibility of the grease
pressure blowing it out.
When lubricating spindle pivot pins, always continue
supplying grease until it comes out of the valve.
INSTALLATION:
RELIEF VALVE
1. Assemble relief valve in the expansion plug.
2. Coat edges of expansion plug with white lead.
3. Using a short piece of tubing or hollow pipe that will clear
