MAINTENANCE
Swing Around Cart Lubrication
There are 10 grease fittings that must be lubricated
with a good grade of lithium based grease after every
5 passes. See Figure 76-1.
• There are 8 grease fittings on the bearing tube
assembly.
• There are 2 grease fittings on the swivel yoke.
Tire and Wheel
Wheel Lug Nut Torque
Wheel lug nuts should be torqued to 125 lb-ft (169.47
N·m). See Figure 76-2.
Check the wheel lug nut torque annually, preseason;
at spring start-up.
Tire Pressures
Proper tire pressure is important! Operating with low
tire pressure will damage the tires and the drive train.
Check tire pressure several times a year:
• Pre-season: At spring start-up.
• During-season: Check tire pressure monthly.
• Post-season: When performing fall winterization.
For the correct tire pressure refer to the decal on the
rim or the tire pressure chart. See Figure 76-3.
!
• TIRES ARE SHIPPED AT A PRESSURE OF 30
TO 35 PSI (206 TO 241 KPA).
• BE SURE THE TIRES HAVE BEEN DEFLATED
TO THE CORRECT PRESSURE (SHOWN ON
DECAL) BEFORE THE TIRE IS USED.
NOTE
• When replacing tires be sure the ply rating of
the new tire is equal to or greater than the ply
rating of the old tire.
