1. Starting Troubles
This concern often surfaces after the Rhino has been in use for approximately a year or has traversed several thousand miles. The issue emerges as an abrupt shutdown of the vehicle, catching the operator off guard. It is also one of the most common problems that many 2006 Yamaha Rhino 660 owners face during their hauls.
Fix The Problem: Frequently, this hitch results from the battery’s age or inadequate upkeep. As the battery’s maintenance is neglected, its capacity to retain a charge diminishes gradually, leading to an eventual inability to fuel the engine. Ultimately, the battery depletes entirely, potentially rendering the vehicle non-operational. If you encounter starting difficulties with your Rhino 660, it is advisable to initially assess the battery’s condition. If the battery is defective then the logical step is to substitute it with a fresh unit. This course of action guarantees optimal battery performance, ensuring the provision of essential power for engine ignition.
2. Dust Build-Up Problem
Among the common problems of this amazing UTV, is the issue of dust buildup significantly troubling Yamaha Rhino 660 users. The presence of a windshield and a rear cab enclosure reduces the chances of this problem by inducing a vacuum-like effect within the cabin, intensifying the accumulation of dirt. This accumulation subsequently obstructs the vehicle’s air filter, impeding the engine’s respiratory capacity. As a result, the vehicle’s capability to exceed the off-road thresholds it was engineered for becomes compromised.
Moreover, the accumulation of dirt can also damage the pistons, shafts, and other crucial engine elements. All of this can easily lead the Rhino 660’s engine to break down as well.
Fix The Problem: To avert the intake of dust, the most effective course of action is to revamp the exhaust system of your Rhino 660. Collaborating with a muffler workshop facilitates the modification of the exhaust system to discharge directly outward (costing approximately $50.00). This will reduce the volume of dust within the cabin and the airborne particulates for trailing vehicles. This solution outweighs the effectiveness of any novelty windshields equipped with vents and similar features.
3. Peculiar Idling
An aggravating concern arises when the engine unexpectedly halts after idling for a brief duration. Typically observed following a few minutes of vehicle operation and the subsequent reduction of speed to an idle state, this issue doesn’t manifest when the engine is cold or during higher-speed offroading. This problem underscores the necessity of promptly diagnosing its underlying cause and rectifying it.
Fix The Problem: Below are some effective solutions to solve this issue immediately!
- Inspecting or Replacing Spark Plugs: A fundamental solution involves examining and, if necessary, replacing the spark plugs. This straightforward process often resolves the issue.
- Carburetor Inspection and Cleaning: Thoroughly check and clean the carburetor, as accumulated dust and debris can lead to complications. Also, examine the vacuum system and fuel filter, both of which could contribute to the issue. Swiftly addressing these measures can alleviate the idling challenge and reinstate optimal engine performance.
4. Full Engine Failures
When a UTV is pushed beyond its intended limits, certain components within the engine can get damaged and become worn, ultimately leading to engine failures.
This is a prevalent issue encountered in numerous 4WD vehicles, including the Yamaha Rhino 660. It’s crucial to comprehend the root causes behind such breakdowns.
The primary concern frequently reported by users is mechanical breakdowns stemming from the gradual erosion of engine components. The prime suspects in such scenarios are typically the crankshaft and pistons, which can suffer damage due to prolonged and strenuous usage.
Fix The Problem: Solving the engine breakdown in a Yamaha Rhino 660 necessitates a thorough inspection of the operating pistons and crankshafts. If wear is detected in the pistons or crankshafts, prompt replacement is paramount to prevent further engine harm. In instances where pistons and crankshafts remain in sound condition, a temporary solution might involve swapping them out to facilitate a temporary engine revival. While this is not a permanent solution, it serves to sustain engine functionality until professional servicing can be arranged.
5. Faulty 4WD Wiring
A frequent issue arises with the malfunction of the vehicle’s servo motor, consequently affecting the integrity of the electrical wiring for the vehicle’s components. If this stems from faulty relays or defective fuses, the resolution can be relatively straightforward. However, if this is the problem, rectification might demand a more comprehensive approach than initially apparent, warranting prompt engagement with an authorized dealership.
Fix The Problem: It is better to adhere to the following 4-step process to inspect for this issue. You should also know that you cannot experiment further with your beast which means you should seek immediate professional assistance to prevent the chances of further damage. For now, take a look at the steps below to fix faulty 4WD wiring!
- Servo Motor Examination: Initiate the process by inspecting the functionality of the servo motor.
- Relay Inspection: Proceed to assess the relays for any signs of malfunction.
- Switch Evaluation: Continue by scrutinizing the switches to ascertain their operational status.
- Wiring Assessment: Conclude the diagnosis by examining the wiring for any issues.
Final Verdict
We cannot argue that the Yamaha Rhino 660 has been an exceptional offroading ride for enthusiasts.
Due to this reason, it has gained much appreciation in terms of its performance as well.
However, with time, it can bother you with its shortcomings too. Therefore, to save you time, we have discussed these shortcomings in detail in this post!
