3. Remove plug allowing oil to drain into drain pans.
4. After oil is drained, apply thread locking
compound on drain plug threads and reinstall
in axle.
5. Fill axle with lubricant; refer to Check Rear Axle.
Checking Steering Cylinder
Bolt Torque (Models 30627 &
30631 only)
Check the steering cylinder mounting bolt torque every
200 hours of operation.
1. Position the machine on a level surface.
2. Check the torque on the steering cylinder mounting
bolts. Torque should be 48–60 ft-lb. (65-81 N-m).

1. Position the machine on a level surface.
2. Clean area around check plug on bidirectional clutch.
3. Rotate clutch so check plug is positioned downward
(Figure 56).
1. Bidirectional clutch
4. Remove check plug allowing all lubricant to flow
into drain pan.
5. Rotate clutch so check plug is positioned at 4
O'clock.
6. Add Mobil Fluid 424 until lubricant level is up to
hole in clutch. Clutch should be approximately 1/3
full.
7. Install check plug.
Note: Do not use engine oil (i.e. 10W30) in
bidirectional clutch. Anti–wear and extreme pressure
additives will cause undesirable clutch performance.
