Fasteners should be replaced with the same class. Make sure fastener threads are clean and that you properly start thread engagement.
This will prevent them from failing when tightening. When bolt and nut combination fasteners are used, torque values should be applied to the NUT instead of the bolt head. Tighten toothed or serrated-type lock nuts to the full torque value. Fasteners should be replaced with the same grade.
Reference: JDS—G Inspect the fitting sealing surfaces. They must be free of dirt or defects. Inspect the O-ring. It must be free of damage or defects.
Lubricate O-rings and install into groove using petroleum jelly to hold in place. Push O-ring into the groove with plenty of petroleum jelly so O-ring is not displaced during assembly. Index angle fittings and tighten by hand pressing joint together to insure O-ring remains in place. Tighten fitting or nut to torque value shown on the chart per dash size stamped on the fitting. Do not allow hoses to twist when tightening fittings. Inspect boss O-ring boss seat. It must be free of dirt and defects.
If repeated leaks occur, inspect for defects with a magnifying glass. Some raised defects can be removed with a slip stone. Put hydraulic oil or petroleum jelly on the O-ring.
Place electrical tape over the threads to protect Oring from nicks. Slide O-ring over the tape and into the groove of fitting. Remove tape. For angle fittings, loosen special nut and push special washer against threads so O-ring can be installed into the groove of fitting. Turn fitting into the boss by hand until special washer or washer face straight fitting contacts boss face and O-ring is squeezed into its seat.
To position angle fittings, turn the fitting counterclockwise a maximum of one turn. Tighten straight fittings to torque value shown on chart. For angle fittings, tighten the special nut to value shown in the chart while holding body of fitting with a wrench. To be used if a torque wrench cannot be used. After tightening fitting by hand, put a mark on nut or boss; then tighten special nut or straight fitting the number of flats shown. Keep gasoline stored in a safe, protected area. DO NOT use de-icers to attempt to remove water from gasoline or depend on fuel filters to remove water from gasoline.
Use a water separator installed in the storage tank outlet. When storing unit or gasoline, it is recommended that you add John Deere Gasoline Conditioner and Stabilizer TY or an equivalent to the gasoline. Use the appropriate oil viscosity based on the expected air temperature range during the period between recommended oil changes. Operating outside of these recommended oil air temperature ranges may cause premature engine failure.
Engine rebuild instructions should be followed closely to determine if special requirements are necessary. Operating outside of the recommended grease air temperature range may cause premature gear transmission failure. DO NOT mix any other greases in this transmission. Use the following gear grease based on the air temperature range. This anti-corrosion grease is formulated to provide the best protection against absorbing moisture, which is one of the major causes of corrosion.
This grease is also superior in its resistance to separation and migration. Use the following grease based on the air temperature range. Operating outside of the recommended grease air temperature range may cause premature failures. DO NOT mix any other greases in this application. Consult with your John Deere Dealer, or Sales Branch, to obtain the alternative lubricant recommendations. If alternative lubricants are to be used, it is recommended that the factory fill be thoroughly removed before switching to any alternative lubricant.
Avoid mixing different brands, grades, or types of oil. Oil manufacturers blend additives in their oils to meet certain specifications and performance requirements. Mixing different oils can interfere with the proper functioning of these additives and degrade lubricant performance. Use clean storage containers to handle all lubricants. Store them in an area protected from dust, moisture, and other contamination. Store drums on their sides. Make sure all containers are properly marked as to their contents.
Dispose of all old, used containers and their contents properly. Manufacturers blend additives in their lubricants to meet certain specifications and performance requirements. Mixing different lubricants can interfere with the proper functioning of these additives and lubricant properties which will downgrade their intended specified performance.
