Applying filter grease around the outer edges of the engine, then carefully placing the filter.

This enhances the resistance of the filter to block dust or debris. Too much dust or sand can jam up on the engine area by easily penetrating the poor air filter, and that might be true for the 660, but we are not sure if the Rhino 700 has the same problem.

Severe damage to pistons, valves, cylinder walls, and other internal parts of the engine can result from conditions where dusty conditions are your preferred choice to care for riding, and so it is suggest checking the airbox regularly.

Look down the throttle body and pull the filter if you find yourself in such an environment. By taking these precautions you will helping to prevent any future problems.

Problems with the engine

A common problem for the Yamaha Rhino 660 is engine failure. This can happen while the Rhino is in motion, and can be very dangerous. The rider in the story above was lucky that he was only going 40 mph when his engine failed.

If he had been going any faster, he could have crashed. The best way to fix this problem is to take your Rhino to a mechanic. They will be able to diagnose the problem and fix it quickly.

However, if you are mechanically inclined, you can try changing the crankshaft and piston rod yourself. This may fix the problem, but it is not guaranteed. Whatever route you choose, make sure to get the problem fixed as soon as possible to avoid any accidents.

Start-up Issues

Rhinos are supposed to be tough, right? But it seems like Yamaha Rhinos may have a bit of a weakness when it comes to their starting issue. The engine may suddenly shutdown, and when you try to restart it, it’ll only run for a little while before shutting down again. You also won’t be able to go fast than 10mph. This can be a sign of neglecting the battery for a long time.

Luckily, changing the battery usually fixes the problem… but only if you’ve been keeping up with maintenance! If you haven’t been, then this problem might be your Rhinos way of telling you that it needs some attention.

Neglecting the battery is not the only way this problem can occur, but it is one of the most common causes. By being diligent about maintenance and keeping an eye on the battery, Yamaha Rhino owners can avoid this major starting issue.

There is a problem with the 4WD wiring on the Yamaha Rhino 660

Among the many problems that can plague an ATV, few are as frustrating as a 4WD wiring problem. Fortunately, there are a few steps that can be taken to troubleshoot the issue. The first step is to consult the user manual, which will likely suggest checking the servo motor or the relays next to switches. If these prove to be not the issue, then it is time to check the wiring.

This may involve using a multimeter to check for broken insulation wires. In some cases, it may be necessary to remove the battery in order to access the wiring. Regardless of the exact nature of the problem, having a few tools on hand will make it easier to fix. With a little time and effort, most 4WD wiring problems can be resolved without too much difficulty.

The tottering clutch

Despite being a relatively uncommon problem, Yamaha Rhino owners should be aware of the potential for tottering clutch issues. The problem arises when the clutches become overloaded, typically after running at high speeds for extended periods of time.

This can cause one or more of the clutches to tip over, resulting in extra weight inside the system. The solution is simple: clean the clutches and add some grease. This will help to lubricate the system and keep the clutches in place. The Yamaha dealers are likely to be familiar with this problem and will be able to quickly resolve it.

An idle problem

If you’ve ever had your Yamaha Rhino 660 stall on you unexpectedly, you know how frustrating it can be. Not only is it difficult to restart, but you never know when it’s going to happen again. Most of the time, this problem can be traced back to idle issues. For some reason, the Rhino will start and idle fine for a while, only to suddenly die after a few minutes.

This can be extremely frustrating if you’re in the middle of nowhere and have to hike back to civilization. While there’s no guaranteed fix, most of the time the problem can be resolved by cleaning the carburetor or changing the spark plug.

However, if you take it to a dealer, they may just try to upsell you on a new fuel pump without actually solving the problem. Either way, it’s important to be aware of this potential issue so that you can be prepared if your Rhino does decide to stall on you.


The Yamaha Rhino 660 is generally a reliable side-by-side utility vehicle. However, there are a few common problems that owners should be aware of. Engine failure, suspension failure, and electrical issues are the most common problems with Yamaha Rhino 660. If you experience any of these problems with your vehicle, it’s important to get them fixed as soon as possible to avoid further damage and expensive repairs.
