Key Features of the LS185B Bobcat
Before diving into the service manual, it’s important to understand the features that define the LS185B skid steer:
- Engine Power: The LS185B is powered by a 56-horsepower, turbocharged diesel engine that provides a balance of power and fuel efficiency. This engine allows the skid steer to operate in tough conditions while minimizing downtime for refueling.
- Hydraulic System: One of the standout features of the LS185B is its advanced hydraulic system. With a maximum auxiliary hydraulic flow of 21.3 gallons per minute (GPM), this skid steer is capable of powering heavy attachments such as augers, breakers, and planers.
- Lifting Capacity: The LS185B has a rated operating capacity of 1,850 pounds, making it highly capable of handling materials, lifting, and digging tasks on construction sites. The vertical lift path provides an extended reach, making it an excellent choice for dumping material into trucks or reaching high work areas.
- Compact Design: With a width of just 68 inches, the LS185B can easily maneuver through narrow spaces and tight job sites. Its compact size combined with high performance gives it a unique advantage in environments where space is limited.
The service manual for the LS185B Bobcat provides operators with essential information on maintaining and troubleshooting the skid steer. Regular maintenance is crucial for ensuring the machine operates at peak performance and extends its lifespan. Below are the key service areas highlighted in the manual:
- Engine Maintenance
- Oil Changes: The engine oil should be changed every 250 hours of operation or once a year, whichever comes first. Using the recommended 10W-30 or 15W-40 oil ensures proper lubrication and extends engine life.
- Air Filters: Check and replace the engine air filter every 500 hours to ensure the engine receives clean air. A clogged air filter can reduce engine efficiency and increase fuel consumption.
- Fuel Filters: Fuel filters should be replaced every 500 hours to ensure the engine gets clean fuel. Contaminated fuel can lead to poor engine performance or even damage to the fuel system.
- Oil Changes: The engine oil should be changed every 250 hours of operation or once a year, whichever comes first. Using the recommended 10W-30 or 15W-40 oil ensures proper lubrication and extends engine life.
- Hydraulic System Maintenance
- Hydraulic Fluid: Change the hydraulic fluid every 1,000 hours or annually. Using the correct fluid is essential to prevent overheating, component wear, and corrosion.
- Hydraulic Hoses and Fittings: Inspect hydraulic hoses for leaks or signs of wear. Hydraulic hoses should be replaced if there are any cracks, bulges, or if they are leaking.
- Auxiliary Hydraulic Connections: Check the auxiliary hydraulic connections and quick-connects regularly for wear or contamination, as issues here can reduce the effectiveness of hydraulic attachments.
- Hydraulic Fluid: Change the hydraulic fluid every 1,000 hours or annually. Using the correct fluid is essential to prevent overheating, component wear, and corrosion.
- Cooling System
- Coolant: Check the coolant level regularly and replace it every two years to prevent engine overheating. Ensure that the radiator is clean and free from debris to maintain optimal cooling efficiency.
- Radiator: Inspect the radiator for any blockages or damage that could impair cooling. A clogged radiator can cause engine overheating, which can lead to severe engine damage.
- Coolant: Check the coolant level regularly and replace it every two years to prevent engine overheating. Ensure that the radiator is clean and free from debris to maintain optimal cooling efficiency.
- Transmission and Drive System
