Adjusting the Front WheelAlignmentService Interval: Every 100 hours/Yearly (whichevercomes first)—Check the front wheelcamber and toe-in.Preparing to Adjust Camber orToe-in1. Check the tire pressure to ensure that the fronttires are inflated to 82 kPa (12 psi).2. Either add weight to the driver's seat equal tothe average operator who will run the machine,or have an operator sit on the seat. The weightor operator must remain on the seat for theduration of the adjustment procedure.3. On a level surface, roll the machine straight back2 to 3 m (6 to 10 ft) and then straight forwardto the original starting position. This allows thesuspension to settle into the operating position.Adjusting the CamberOwner provided tools: spanner wrench, Toro PartNo. 132-5069; refer to your Authorized ServiceDealer.Important: Make the camber adjustments onlyif you are using a front attachment or if there isuneven tire wear.1. Check the camber alignment at each wheel; thealignment should be as close to neutral (zero)as possible.Note: The tires should be aligned with the treadevenly on the ground to reduce uneven wear.2. If the wheel camber is out of alignment, use thespanner wrench to rotate the collar on the shockabsorber to align the wheel (Figure 58).g033218Figure 581. Shock-absorber spring 3. Spring length2. CollarAdjusting the Front Wheel Toe-inImportant: Before adjusting toe-in, ensure thatthe camber adjustment is as close to neutral aspossible; refer to Adjusting the Camber (page 47).1. Measure the distance between both of the fronttires at the axle height at both the front and rearof the front tires (Figure 59).g009235Figure 591. Tire center line—back 3. Axle center line2. Tire center line—front2. If the measurement does not fall within 0 to6 mm (0 to 1/4 inch), loosen the jam nuts at theouter end of the tie rods (Figure 60).g033219Figure 601. Tie rod 2. Jam nut3. Rotate both tie rods to move the front of the tireinward or outward.4. Tighten the tie rod jam nuts when the adjustmentis correct.5. Ensure that there is full travel of the steeringwheel in both directions.47
