John deere repair manual la110

Do not inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel. When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available. Check wheels for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.

Direct exposure to hazardous chemicals can cause serious injury. Potentially hazardous chemicals used with John Deere equipment include such items as lubricants, coolants, paints, and adhesives. A Material Safety Data Sheet MSDS provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques.

Check the MSDS before you start any job using a hazardous chemical. That way you will know exactly what the risks are and how to do the job safely. Then follow procedures and recommended equipment.

Keep hands and feet away while machine is running. Shut off power to service, lubricate or remove mower blades, augers or PTO shafts.

Improperly disposing of waste can threaten the environment and ecology. Potentially harmful waste used with John Deere equipment include such items as oil, fuel, coolant, brake fluid, filters, and batteries. Use leakproof containers when draining fluids.

Do not use food or beverage containers that may mislead someone into drinking from them. Do not pour waste onto the ground, down a drain, or into any water source. Inquire on the proper way to recycle or dispose of waste from your local environmental or recycling center, or from your John Deere dealer.

Explosive release of fluids from pressurized cooling system can cause serious burns. Shut off machine. Only remove filler cap when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely. Before returning machine to customer, make sure machine is functioning properly, especially the safety systems. Install all guards and shields.

Fastener Torques DO NOT use these hand torque values if a different torque value or tightening procedure is given for a specific application. Check tightness of fasteners periodically. DO NOT use air powered wrenches. Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical grade. 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. Reference: JDS - G Fasteners should be replaced with the same grade. Keep all dirt, scale, water or other foreign material out of gasoline. 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 machine 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.

After the break-in period, use the John Deere oil that is recommended for this engine. John Deere Dealers: You may want to cross-reference the following publications to recommend the proper oil for your customers:.

ONLY use a quality break-in oil in rebuilt or remanufactured engines for the first 5 hours maximum of operation. Engine rebuild instructions should be followed closely to determine if special requirements are necessary. Consult with your John Deere Dealer, or Sales Branch, to obtain the alternative lubricant recommendations. Use of alternative lubricants could cause reduced life of the component.

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. Lubricant Storage All machines operate at top efficiency only when clean lubricants are used.

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. Mixing Of Lubricants In general, avoid mixing different brands or types of lubricants.

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. Hydrostatic Transmission Oil Chassis Grease Use the following grease based on the air temperature range.

Operating outside of the recommended grease air temperature range may cause premature failures. These machines are equipped with a internal wet disc brake transmission.

Momentarily place a jumper wire from solenoid terminal to battery positive terminal. NOTE: If battery voltage drops below 9 volts when cranking engine or while engine is running, the solenoid will not function.

Move throttle lever to FAST idle position detent. Hole in governor control lever must align with hole A in governor control plate. Loosen throttle cable clamp B. Slide the throttle cable left or right to align holes. Tighten throttle cable clamp B. If solenoid now clicks, the solenoid is working properly. To test proper operation of fuel shutoff solenoid.

When servicing engine when the engine is running , it is important to remove hood to avoid damage from muffler exhaust heat source. Remove hood assembly. Move throttle lever to FAST idle position. Do not bend governor link or distort governor lever. While holding throttle in fast position use a flat blade screwdriver to turn governor shaft clockwise until it stops.

Hold lever and shaft in position and tighten governor lever bolt and nut to specification. Reason: To verify the engine speed settings are within limits. Bend the upper governor spring anchor A to adjust the top no load engine rpm to specification. Bend the anchor up to lengthen the spring to increase the rpm, or down to shorten the spring to reduce the engine rpm. In order to obtain correct operation of the carburetor, the adjustment procedure must be performed in the sequence shown.

Hold throttle shaft A in closed position with finger, adjust idle speed screw B to rpm. Release throttle. Move throttle to idle position. Starting with a cold engine, remove valve cover. Turn idle speed screw A to obtain rpm minimum. Remove the limiter cap from the idle mixture screw B. Then turn idle mixture screw B slowly clockwise until engine just begins to slow. Note position of slot on screw. Now turn idle mixture screw B in counterclockwise direction until engine just begins to slow.

Turn screw to midpoint between speed changes. Insert a screwdriver through the spark plug opening A until it touches the top of the piston. Continue to turn the crankshaft clockwise until the piston has moved down 6.

Move throttle control from idle to high speed position. Engine should accelerate smoothly. There should be no afterfire. Specification: Carburetor Slow Idle Speed. Valve Clearance Adjustment NOTE: Correct position of crankshaft is necessary to eliminate interference by the compression release mechanism on the cam gear when adjusting valve clearance.

Check valve clearance with a feeler gauge between valve stem and rocker arm. Valve clearance should be 0. If not, adjust as necessary using a 13 mm open end wrench and a 5 mm hex wrench. Tighten lock nut to 6. Recheck clearance and make adjustments if necessary. Install valve cover. Lock nut. Valve Clearance Intake. Specifications: Armature Air Gap. Armature Mounting Screws.
