The Honda Pioneer 520 side-by-side is a perfect blend of power and maneuverability. It features a 518cc engine and a five-speed automatic transmission, delivering plenty of performance. Besides, its 50-inch width helps it to navigate tight trails that other UTVs can’t.
The versatility of this side-by-side allows you to handle more daily tasks off the beaten path. You can use it for adventurous excursions, farming, hauling garden equipment, or hunting.
However, the Pioneer 520 is not immune to problems. Poor maintenance or improper use may lead to Honda Pioneer 520 problems like hard shifting gears, power loss, clutch overheating, and battery not charging. Sadly, some issues can cause irreversible damage if not addressed on time.
Do you own a problematic Honda Pioneer 520? Herein, I’ll guide you on how to fix this UTV.
Hard to Shift Gears
While the Pioneer 520 is popular for its five-speed automatic transmission, issues may crop up over time and affect the smooth shifting. Problems shifting gears may arise due to poor maintenance or parts wearing out due to excessive use.
The transmission fluid could be to blame if your side-by-side doesn’t shift gears easily. A low transmission fluid level causes lubrication problems within the system. As a result, moving parts get stuck, making it hard to shift gears.
The fluid may become dirty or contaminated and lose its effectiveness. Dirty transmission fluid will also clog the transmission filter and block fluid flow. So, when troubleshooting a gear-shifting problem, start with the transmission fluid.
Ensure the fluid is within the recommended level, or top it off if not. If the fluid looks dark or discolored, it might be contaminated and needs changing. When changing dirty/contaminated fluid, remember to remove a dirty/clogged filter and install a new one.
If fixing the fluid and filter doesn’t resolve the shifting issue, your transmission might have worn or damaged components. In this case, it’s advisable to allow a professional to inspect the clutch and shift linkage for defects. The professional may repair or replace any defective part causing gears not to shift.
Clutch overheating is one of the most reported Honda Pioneer 520 problems. Failure to resolve this issue may cause gear slipping problems, power loss, or complete clutch failure.
Your side-by-side requires the clutch to transmit torque to the transmission. If the clutch overheats and fails, you will experience several performance issues. But what causes the Pioneer 520’s clutch to overheat?
Two reasons explain why your UTV’s clutch overheats. First, overloading your side-by-side puts more strain on the clutch, causing it to overwork. The clutch will work harder to handle the excess weight, thus overheating.
If you’ve exceeded the maximum load limit for your UTV, reducing it can help resolve overheating. Check your side-by-side’s owner’s manual to understand its maximum load limit.
The clutch may also overheat due to low-speed activities. Hauling equipment or driving in harsh terrain means lowering the speed. You’ll also need to press the gas pedal to maintain constant movement.
The low speed and constant force can cause the clutch to overheat. When this happens, put the UTV in neutral or park and give it some time to cool. Alternatively, take your Pioneer 520 to a professional to upgrade the clutch.
Power Loss Problem
Engine losing power while climbing steep hills is another common problem with the Pioneer 520. Its engine is powerful enough to cruise rugged terrains and steep inclines. However, several issues with the fuel system, combustion chamber, and air intake may cause a power reduction problem.
The leading cause of power loss is a clogged or damaged fuel system. Clogs in the system block fuel flow to the combustion chamber. The engine runs too lean due to insufficient fuel and loses power. Damaged or clogged fuel injectors can also cause reduced fuel flow into the combustion chamber.
Cleaning the fuel lines with compressed air and fuel injector cleaner can help fix the issue. Then, replace a clogged fuel filter or damaged fuel injectors.
Another possible cause of the power loss problem is a blocked air filter. This filter restricts airflow to the engine, leading to power loss. Replacing this filter may resolve the problem.
Faulty spark plugs may also cause loss of power in your Pioneer 520. If the plugs fail to supply the required spark in the combustion chamber, the fuel mixture won’t burn to power the vehicle.
Check the plugs, scrub them with sandpaper, and spray some brake cleaner to remove rust. Secure the plugs in the sockets to create a contact if they are loose. If the plugs appear damaged beyond repair, replace them.
Some Honda Pioneer 520 problems may occur over time due to bumpy rides or hitting obstacles. For example, the side-by-side suspension system will act out after tackling rough terrains for an extended period.
The manufacturer designs the UTV’s suspension system to handle rough terrain. However, the suspension may start to wear or sag after a while. The springs, bushings, and shocks are more susceptible to wear or damage.
If you experience abnormally rough rides, inspect these suspension components for signs of damage. Replacing any damaged parts may resolve the problem.
Suspension issues may also occur if you neglect routine maintenance, such as adjusting tire pressure. Adjust the tire pressure to the recommended level.
Ensure you have appropriately adjusted suspension settings based on your driving conditions. If you can’t adjust the settings at home, take the side-by-side to a professional to make the necessary adjustments.
Battery Not Charging
Battery not charging may cause problems such as starting difficulties and electrical components failure. Unfortunately, this is another problem that may occur due to poor maintenance, regular usage, and driving conditions.
Your Pioneer 520 battery may fail to charge due to a faulty alternator. Moreover, the alternator belt may wear out or become loose. You can start by replacing a damaged alternator belt. If the alternator is defective, hire a specialist to repair or replace it.
If the charging issue persists, your battery could be to blame. Check for corrosion on the terminal cables and clean them. A wire brush or hot water will help you clean the terminals. Then, ensure the terminal connections are tight.
If none of these fixes works, you might have a bad battery. You can replace a battery that has lost its ability to hold power.
No Power Steering
One of the downsides of this side-by-side is that it doesn’t have power steering. It’s worth noting that some riders may prefer the manual steering system in this UTV when navigating trails.
Power steering can be handy when riding on challenging terrain. This steering makes your work easier and reduces fatigue, especially when maneuvering tight spaces. Do you prefer power steering over manual steering?
If so, you can improve your riding experience by hiring a professional mechanic to add power steering to the UTV. Luckily, there are many aftermarket power steering kits you can use. Your mechanic will help you find and install the best kit.
Adjust your Pioneer 520’s tire pressure to make the UTV easier to steer. Install a steering damper to absorb vibration and shocks while riding on rugged terrain. The damper will also reduce the effort needed when navigating.
Despite these issues, the Pioneer 520 is a side-by-side anyone will want to keep closer. It’s versatile and reliable around farms, properties, and fields. Unfortunately, poor maintenance, riding conditions, and improper handling may trigger several problems.
If you encounter the above Honda Pioneer 520 problems, determine the cause and fix them. Addressing these problems on time can prevent other issues from cropping up or avoid permanent damage. If you encounter glitches you can’t fix at home, take the side-by-side to a professional mechanic for help.
