UTV Drivetrain & Transmission Parts

While the motor generates power, the transmission is responsible for optimizing this power at different speeds and loads. The torque created by an internal combustion engine remains high enough in a relatively narrow range, and the gearbox enables you to keep it running within this very range with maximum possible output and fuel efficiency. As for the drivetrain system, it transfers torque from the gearbox to the wheels, and its type greatly defines off-road performance. Some models have one drive axle, others have two or even more drive axles equipped with a locking differential.

When it comes to all-terrain vehicles, they can be chain- or shaft-driven. Market-leading manufacturers tend to use shafts in most of their models, although some older ATVs along with smaller and less powerful quads for kids are equipped with a chain rotating the rear axle. Any of these systems has its pros and cons and needs proper maintenance. The chain has to always be lubed and tightened well, and it's wise to check it before venturing out. Shaft drive allows for designing reliable and capable AWD systems that require gear oil, and this liquid has to be regularly changed and remain free from dirt and water.

A weak spot of many drive systems is their CV joints, or their rubber boots, to be exact. A quad is hardly ever employed on a paved road, and there are plenty of sharp stones, tree branches, and other things that often remain unnoticed on the ground and tear the boots. It's crucial to notice such damage timely and replace the boot unless you want to replace the whole joint that gets open to dust and water. There are different repair kits including boots, clamps, grease, and even special tools making the replacement process not as complicated. Reputable companies produce their boots from strong and durable sorts of rubber, so they don't crack after just a season of use.

The most popular type of transmission in ATVs, side-by-sides, and snowmobiles is a CVT, or PVT, like Polaris calls this mechanism in its models. With the introduction of the Trail Boss in the mid-1980s, the company actually pioneered the use of this assembly on the ATV market, just a couple of years after such a setup had become popular in sporty sleds by this brand. These days, CVTs are more complex, effective, and durable, but still, they need some maintenance including visual inspection, cleaning, and replacing the belt and some hardware. Besides, there are hydrostatic CVT assemblies that use hydraulic fluid and need it to be changed together with the filter.
