MAINTENANCE
Spindle Housing Bolts -
These bolts fasten the spindle housing to the deck. The bolts should be checked for tightness each morning before the unit is started. They should be torqued to 400 ft./lbs.
Motor Bolts
Examine the bolts that fasten the hydraulic motor onto the spindle housing. Tighten to 85 ft./lbs.of Torque. If these bolts become loose the motor could shift back and forth on the spindle housing breaking the motor flange.
Speed Changer Bolts
The bolts that fasten the mount plate to the tractor and the bolts that fasten the speed changer to the adapter plate are part of this maintenance. These bolts can become loose through vibration and should be checked. If left loose, misalignment of the speed changer and tractor PTO could result which could damage the speed changer. The speed changer bolts should be torqued to 100 ft./lbs. The mount plate bolts should be torqued in
accordance with the following bolt sizes: 1/2" - 100 ft./lbs.; 5/8" - 160 ft./lbs.; | 7/8" - 400 ft./lbs. |
Pump Bolts
The bolts that fasten the pump to the speed changer should be checked, as these could become loose through vibration. They should be torqued to 100 ft./lbs.
Axle Arm Bolts
Inspect the axle arm bolts for proper tightness. The nut should not be loose. DO NOT over tighten these bolts. Tighten the nut on the bolt until it contacts both ears. Then tighten it 1/2 revolution more. The axle arm must be free to move up and down. If one of these bolts slipped out, the suspension system would fail.
Winch Stand Bolts
These bolts fasten the winch stand to the deck. These bolts should be checked each morning before the machine is started. If the winch stand has any play, forward or backward, these bolts need to be tightened. Extreme forces are transmitted thru the winch stand when the wings are raised. If the bolts are loose the winch stand could twist or break.
Drawbar Bolt
Inspect the drawbar bolt for fit. The nut should be pulled up on the bolt such that the clevis is held straight on the drawbar. Use the washers provided to shim any difference between the clevis opening and the drawbar thickness. This will assure proper action of the tongue and clevis. If the tongue clevis sags down, the nut should be tightened.
Blade Carrier Retaining Nut
Check that the cotter pin is present and not damaged. If the nut is missing, retorque as described in Blade Carrier Installation.
