Additionally, investigate unusual noises or vibrations, which may indicate loose parts or worn components. Refer to the manual for specific diagnostic steps and safety precautions before attempting repairs.
Engine Problems
Common engine issues include failure to start, loss of power, or excessive smoking. Check the fuel supply, ensuring the fuel filter isn’t clogged. A faulty spark plug or ignition coil can prevent starting. Low oil levels trigger safety shutdowns – verify the oil level is correct.
If the engine overheats, inspect the coolant level and radiator for obstructions. A dirty air filter restricts airflow, reducing performance. Consult the manual for detailed troubleshooting steps and safety guidelines.
Deck and Blade Issues
Uneven cutting often stems from dull or damaged blades. Sharpen or replace blades, ensuring they are balanced to prevent vibration. Check for debris buildup under the deck, hindering performance. A loose or damaged deck belt causes slippage and poor cutting quality.
Inspect the blade spindles for wear and proper operation. Ensure all hardware is tightened securely. Regularly cleaning the underside of the deck prevents rust and maintains optimal cutting efficiency. Always disconnect the spark plug before working on the deck!
Fluid Specifications
For optimal engine performance, use SAE 30 oil with an API service classification of SJ or higher. The LT155 requires approximately 1.7 quarts with a filter change. Regarding coolant, a 50/50 mix of ethylene glycol antifreeze and distilled water is recommended.
The cooling system capacity is roughly 1 gallon. Always refer to the John Deere specifications for the most accurate fluid types and capacities. Using incorrect fluids can cause engine damage and void your warranty. Regularly check fluid levels!
Oil Type and Capacity
John Deere recommends utilizing SAE 30 oil, meeting API service classification SJ or higher, for your LT155’s engine. For temperatures below 32°F (0°C), consider a 10W-30 oil for easier cold-weather starting. The engine oil capacity is approximately 1.7 US quarts when changing the oil and filter simultaneously.
Always verify the oil level using the dipstick, ensuring it falls within the designated “full” range. Regular oil changes, using the correct type and amount, are crucial for extending engine life and maintaining peak performance.
Coolant Type and Capacity
The John Deere LT155 requires a high-quality ethylene glycol antifreeze/coolant. It’s vital to use a coolant that meets or exceeds John Deere’s specifications to prevent corrosion and ensure optimal cooling system performance. A 50/50 mix of coolant and distilled water is generally recommended for all-weather protection.
The cooling system capacity is approximately 1.25 US gallons. Regularly check the coolant level and inspect for leaks. Maintaining the correct coolant mixture is essential for preventing overheating and engine damage, especially during warmer months.
Belt Replacement
Replacing belts on your John Deere LT155 is a crucial maintenance task. Worn or damaged belts can significantly impact the tractor’s performance. Always disconnect the spark plug wire before beginning any belt replacement procedure for safety. Proper tensioning is vital after installation; too loose, and it will slip, too tight, and it will damage bearings.
Refer to the parts diagrams to identify the correct belt for your specific application – deck or drive. Carefully note the belt routing before removal to ensure correct reinstallation. Regular inspection prevents unexpected breakdowns.
Deck Belt Replacement
Replacing the deck belt on your LT155 requires careful attention. First, disconnect the spark plug wire! Remove the mower deck, then locate the belt routing diagram – often found on the deck itself or in the owner’s manual. Release tension on the idler pulleys to remove the old belt.
Install the new belt, ensuring it’s correctly seated in all grooves and around the pulleys. Re-engage the idler tension and double-check the routing before reinstalling the deck. Proper belt alignment is critical for efficient cutting.
Drive Belt Replacement
Replacing the drive belt on your LT155 involves several steps for proper function. Disconnect the spark plug wire for safety! Access the belt by removing the fender deck and any associated covers. Carefully release the tension on the belt tensioner to remove the worn belt;
Install the new belt, ensuring correct routing around the transmission pulley and engine pulley. Re-engage the tensioner and verify the belt is seated correctly. Reinstall the fender deck and covers, then test the drive system.
Blade Sharpening and Balancing
Maintaining sharp blades is crucial for a quality cut. Remove the blades and securely mount them to a balancing device. Grind each blade to restore the original cutting edge, ensuring equal length on both sides. An unbalanced blade causes excessive vibration and damage;
After sharpening, check for balance; if one side is heavier, grind material from the heavier side until balanced. Reinstall the blades with the cutting edges facing upwards, tightening to the specified torque.
Filter Replacement
Regular filter changes are vital for engine health. The oil filter (AM125424 or GY20577) should be replaced with each oil change, ensuring clean lubrication. The in-line fuel filter (AM107314) prevents debris from reaching the carburetor.
The air filter kit (GY20574) protects the engine from dust and dirt. Inspect filters frequently and replace when dirty. Proper filtration extends engine life and maintains optimal performance. Always dispose of old filters responsibly.
Oil Filter Replacement
Begin by warming the engine slightly for easier oil flow. Locate the oil filter (AM125424 or GY20577) and position a drain pan beneath it. Using an oil filter wrench, carefully loosen and remove the old filter, being mindful of residual oil.
Lightly lubricate the gasket of the new filter with fresh oil before hand-tightening it into place. Ensure a secure fit, but avoid over-tightening. Properly dispose of the used filter and refill the engine with the correct oil type and capacity.
Air Filter Replacement
To maintain optimal engine performance, regularly replace the air filter (GY20574 air filter kit). Locate the air filter housing, typically on the side of the engine. Release any retaining clips or screws and carefully open the housing. Remove the old air filter, noting its orientation for correct installation of the new one.
Ensure the new filter is properly seated and the housing is securely closed. A clean air filter prevents debris from entering the engine, prolonging its life and efficiency. Inspect the housing for any damage during replacement.
Electrical System Overview
