Item     Qty     Part     Specification Description    
Low Ground Pressure (LGP) machines have an inner hub that is wider than the hub on the standard machines. Both machines have the same specifications and the same installation procedure    
1     Each side has four friction discs and three parking brake plates.
Before assembly, dip the parts in the SAE 30 oil.
Thickness of four new friction discs and three new parking brake plates for the brake is 22.90 0.87 mm (0.902 0.034 inch).    
4 170-8714 Friction Disc     Thickness of one new friction disc is
4.00 0.12 mm (0.157 0.005 inch).    
3 3W-5159 Parking Brake Plate     Thickness of one new parking brake plate is
2.30 0.13 mm (0.091 0.005 inch).    
2     2     5F-0585 Bearing Cone     The bearing cone may be frozen in order to aid installation.
Heat the bearing cone to
120°C (248°F) for a maximum of eight hours.
After the assembly has cooled, position and install the bearing cone squarely against the locating shoulder.    
3     2     5F-0589 Bearing Cup     Before installation, lubricate the bearing surfaces with SAE 30 oil.

8     9     6V-3823 Bolt     Procedure for Preloading the Sprocket Bearings:
1. The parts must be clean and free of dirt. Lubricate bearings with SAE 30 oil.
2. Continuously rotate sprocket hub (B) .
3. Seat bearings against plate (C) . Gradually apply an axial load of
120000 10000 N (27000 2250 lb).
4. Tighten three equally spaced bolts (8) with an axial load against plate (C) to
95 10 N m (70 7 lb ft).
5. Remove the axial load from plate (C) .
6. Tighten all bolts (8) to
120 20 N m (88 15 lb ft).    
9     1     2H-6489 Bearing Outer Race     Before installation, lubricate with SAE 30 oil.
The bearing may be frozen in order to aid installation.
Heat the bearing to
120 °C (248 °F) for a maximum of eight hours.
After the assembly has cooled, position and install the bearing squarely against the locating shoulder.    
10     1     6Y-0859 Duo-Cone Seal Gp     All the surfaces that are contacting the rubber toric seals must be clean and dry at assembly. Before assembly, apply a thin film of oil to the contacting surfaces of the
