Service Manual 6-5
Inspection
• Check all threaded components for damaged or
stripped threads. Repair light damage with thread
chasers. Replace parts found to be unserviceable.
• Clean all parts of dirt and debris.
• Inspect parts for wear or damage. Replace as
needed.
Installation
See Figure 6-6.
Installation is the reverse of the removal procedure.
Figure 6-6: Alignment Pin
• Verify proper alignment. Locate alignment pin (13)
with hole (14) in frame while installing upper plate
(15).
FRONT END ALIGNMENT
Proper front end alignment is essential to tractor
performance and longevity. Proper alignment ensures
efficient steering and maximum tire life. Check the
alignment at routine intervals or after any heavy impact to
the front axle.
Preparation
• Properly adjust front end bearings. (See “FRONT
WHEEL BEARINGS” on page 6-8.)
• Check to ensure that the steering tie rod, drag link
ends, and king pins are not loose.
• Check the tires for proper inflation pressure and that
the rim-to-floor are the same at each wheel. (See
“TIRE PRESSURE” on page 2-11.)
• Check the wheel installation.
Checking and Correcting Toe
See Figure 6-7.
Figure 6-7: Toe (viewed from above)
Toe-in is when the distance between the front wheels is
less at the front of the axle than it is at the rear. Toe-in
can cause excessive tire wear and unstable steering.
Checking the Toe
NOTE
A work bay is needed for this procedure.
1. Slowly drive the truck into the bay.
2. Park and prepare tractor for service. (See “Park
Tractor Safely” on page 1-3.)
3. Apply marks approximately 127 mm (5 in) up on the
front side of both tires. Be sure the mark is parallel to
the center tread rib.
4. Apply marks approximately 127 mm (5 in) up on the
