Understanding the common problems that can plague these ATVs can help owners diagnose issues quickly, perform preventative maintenance effectively, and ultimately keep their machines running smoothly for years to come. Let's dive into the specifics of these common gremlins and how to address them.
So, What Are the Most Common Arctic Cat 700 Issues?
While the Arctic Cat 700 boasts a reputation for ruggedness, several recurring problems tend to surface more frequently than others. These issues range from relatively minor annoyances to more serious mechanical failures that can leave you stranded on the trail. Let's break down some of the usual suspects:
Starting Problems: One of the most frustrating issues reported by Arctic Cat 700 owners is difficulty starting, especially in cold weather. This can stem from a variety of factors, including:
- Weak Battery: This is a common culprit. Cold temperatures significantly reduce battery performance. A load test can determine if your battery is holding a sufficient charge.
- Faulty Starter Solenoid: The solenoid relays power from the battery to the starter. A click when you turn the key, but no cranking, often indicates a bad solenoid.
- Clogged Fuel Injector: Over time, fuel injectors can become clogged with debris, restricting fuel flow and making starting difficult. Fuel injector cleaner can sometimes resolve this, but replacement may be necessary.
- Low Compression: Worn piston rings or valve issues can lead to low compression, making it hard for the engine to ignite the fuel-air mixture. A compression test can confirm this.
Electrical Issues: ATVs, with their exposure to the elements and rough terrain, are prone to electrical problems. Arctic Cat 700s are no exception:
- Faulty Voltage Regulator: The voltage regulator maintains a consistent voltage to the battery and electrical components. A failing regulator can overcharge or undercharge the battery, damaging it and other electrical systems. Signs include dimming lights, a constantly dead battery, or burnt-out bulbs.
- Stator Problems: The stator generates the electrical power used by the ATV. A failing stator can cause a dead battery, poor engine performance, and starting issues.
- Wiring Harness Issues: Vibration and exposure to the elements can cause wires to chafe, corrode, or break, leading to a variety of electrical problems. Inspecting the wiring harness for damage is crucial.
- Faulty Speed Sensor: This often triggers the ECU and can cause the speedo/odometer to malfunction, the unit to run poorly or not at all and can cause other electrical system issues.
Fuel System Problems: A properly functioning fuel system is essential for optimal engine performance. Issues here can lead to poor running, stalling, and starting difficulties:
- Fuel Pump Failure: The fuel pump delivers fuel from the tank to the engine. A failing pump may not provide enough fuel, causing the engine to stumble or stall, especially under load.
- Clogged Fuel Filter: A clogged fuel filter restricts fuel flow, leading to similar symptoms as a failing fuel pump. Regular replacement is key.
- Dirty Carburetor (Older Models): Some older Arctic Cat 700 models used carburetors. These can become clogged with debris, requiring cleaning or rebuilding.
- Faulty Throttle Position Sensor (TPS): The TPS tells the ECU the position of the throttle. A faulty TPS can cause erratic engine behavior.
Cooling System Issues: Overheating can cause serious engine damage. Keeping the cooling system in top condition is vital:
- Radiator Clogs: Mud, debris, and even insects can clog the radiator fins, reducing its ability to dissipate heat. Regular cleaning is essential.
- Faulty Thermostat: The thermostat regulates engine temperature. A stuck-closed thermostat can cause overheating, while a stuck-open thermostat can prevent the engine from reaching its optimal operating temperature.
- Water Pump Failure: The water pump circulates coolant through the engine. A failing pump can lead to overheating.
- Leaking Hoses or Radiator: Leaks in the cooling system can reduce coolant levels, leading to overheating. Regular inspection and replacement of damaged hoses are important.
Suspension and Steering Problems: A properly functioning suspension and steering system is crucial for handling and safety:
- Worn Ball Joints: Ball joints connect the suspension components. Worn ball joints can cause loose steering and clunking noises.
- Worn Tie Rod Ends: Tie rod ends connect the steering rack to the wheels. Worn tie rod ends can lead to sloppy steering.
- Damaged Shocks: Shocks absorb bumps and provide a smooth ride. Damaged shocks can result in a bouncy or uncomfortable ride.
- A-Arm Bushing Wear: A-arm bushings stabilize the suspension components. Wear can cause loose handling.
Other Common Issues:
- CV Joint Failure: CV joints transfer power to the wheels. They are prone to damage from water, mud, and debris. Clicking noises when turning often indicate a failing CV joint.
- Brake Problems: Worn brake pads, leaking brake lines, or a faulty master cylinder can compromise braking performance.
- Transmission Issues: Slipping gears, difficulty shifting, or unusual noises can indicate transmission problems.
Digging Deeper: Troubleshooting and Solutions
Now that we've identified the common problems, let's look at some troubleshooting steps and potential solutions:
