Dial Indicator Placement
Radial Ring Inspection If a worn radial ring is suspected to be the cause of play in the drive unit, perform the following steps to determine if the rings should be replaced.
Use extreme care when the lift truck is jacked up. Never block the lift truck between the operator platform and the floor; this presents a tipping hazard. Keep hands and feet clear while jacking the lift truck. After the lift truck is jacked, place solid blocks or jack stands beneath it to support it. Do not rely on the jack alone to support the lift truck. See “Jacking Safety” on page 2-9. 1. Jack the rear of the truck up until the drive tire clears the floor. 2. Place a magnetic base dial indicator on the tractor bumper. Place the indicator pin on top of the ring gear. See Figure 7-36. NOTE: When positioning the indicator, try to align it with a feature on the truck (such as a grease fitting). This helps maintain consistent results between trucks. 3. Zero the indicator and lower the truck to the floor. Observe the new indicator reading. 4. If the reading exceeds 0.090 in. (2.3 mm), replace the radial rings.
Axle Seal and Bearing Removal 1. Remove the drive wheel. 2. Reconnect the battery connector and turn the key switch ON. Turn the steering tiller completely clockwise (to the right). The drive unit cover plate now faces the tractor bumper. Turn the key switch OFF and disconnect the battery connector. 3. Place a drain pan under the drive unit. Remove the drain plug and drain the drive unit. Drive unit capacity is 7.1 quarts (6.75 liters). 4. Apply gasket sealant (P/N 990-520) to the drain plug and reinstall drain plug. 5. Remove the cover plate from the drive unit housing.
