Wheel Alignment

When the unit is new, both axles are preset at the factory with .3175 - .635 cm (1/8" – 1/4") tow-in and should not require
any initial adjustment. Adjustment may be required if steering components have been damaged or replaced. Toe in
adjustments should be made by qualified personnel.

Trailing adjustment

Through normal use or after unit has been repaired some maintenance with respect to the tracking alignment may be
required.
If the rear axle begins to track excessively left or right of the front axle (dog track), then corrective adjustment is made by
lengthening or shortening the tie rod at the rear of the wagon, between the rear axle plate assembly, and the right steering
spindle.
Loosen jam nuts at the left and right of the rear tie rod to allow free rotation of the tie rod.
Rotate the tie rod to lengthen or shorten as required (see diagram below).
When adjustment is complete, tighten the jam nuts to secure the setting.
Test drive the wagon and check for front to rear trailing, repeat adjustment as required.
When the wagon is being trailed empty, it should track slightly left. When the wagon is loaded it may track slightly to the
right. The weight causes normal distortion to the steering geometry which affects the tracking when loaded.
