Review POLARIS Complete Bottom End Crank Read fits XCR800 2001

The Polaris XC 800 bottom end crank, model number EC79PL012, is a crucial component of the Polaris XC 800 ATV engine. This crankshaft is specifically designed for Polaris XC 800 series all-terrain vehicles produced in the year 2001.

The bottom end crank is the heavy-duty part of the engine, responsible for converting linear reciprocating motion into rotational power. It is machined from high-strength steel to withstand the extreme conditions and heavy loads that off-road riding imposes on an ATV engine. Its precision-balanced design ensures smooth engine operation, reducing vibration and providing a more comfortable riding experience.

The crankshaft consists of a crankpin assembly and connecting rods that connect the crankshaft to the pistons. The crankpin assembly features six journal bearing surfaces, each designed to accommodate a crankshaft journal and one connecting rod bearing. These precision-machined bearing surfaces ensure a close fit between the crankshaft and the bearings, reducing friction and enhancing power transfer efficiency.

Moreover, the crankshaft is designed with a forged steel bearing cap, providing the strength and durability needed to withstand the forces generated by the engine. The bearing cap is also designed to facilitate easy maintenance, with accessible bearing surfaces for simple and efficient replacement.

The Polaris XC 800 bottom end crank's robust design makes it appropriate for various off-road conditions and applications. It is a perfect fit for operators seeking high performance, reliability, and longevity in their Polaris XC 800 ATV. By replacing a worn-out or damaged crankshaft with a polySARIS EC79PL012, you can restore your ATV engine's balance, power, and efficiency. This genuine OEM Polaris part is designed to meet or exceed OEM specifications, ensuring a perfect fit and seamless compatibility with your Polaris XC 800 all-terrain vehicle.

Pros and Cons of Buying a Polaris EC79PL012 2001 XCR800 Bottom End Crank

a. Durability: A bottom end crank is a critical component of a snowmobile engine, and the Polaris EC79PL012 is known for its robustness. It is engineered to handle the extreme conditions of snowmobiling.

b. Replacement Part: A worn-out or damaged bottom end crank can render a snowmobile unusable. By having a replacement on hand, you ensure your snowmobile stays operational.

c. OEM Part: The Polaris EC79PL012 is an original equipment manufacturer (OEM) part, meaning it is specifically designed for the Polaris XCR800 model. This guarantees a perfect fit and optimum performance.

a. Cost: Replacing a bottom end crank can be quite expensive, with the Polaris EC79PL012 likely costing more than other aftermarket alternatives.

b. Labor Costs: If you're not a mechanic, you'll need to hire a professional to install the crankshaft for you, adding additional costs.

c. Time Consuming: Installing a new crankshaft is a complex process that involves disassembling the engine, replacing the old crankshaft, and reassembling the engine. This can take several hours, or even days, depending on your mechanical expertise.

In summary, the Polaris EC79PL012 2001 XCR800 bottom end crank is a vital component for maintaining the functionality and performance of your snowmobile. Its durability and OEM specifications ensure a perfect fit, but the cost and time investment required for replacement may deter some buyers.

If you're an avid snowmobiler who frequently rides in extreme conditions or operates your machine extensively each season, investing in a high-quality replacement bottom end crank, such as the Polaris EC79PL012, is a wise investment. On the other hand, if you're a casual snowmobiler or your budget is limited, you may want to consider investing in routine maintenance and replacing the bottom end crank only when it's absolutely necessary. Always remember, a well-maintained snowmobile is a safer and more enjoyable ride.

Details:

2001 Polaris XCR800 Complete Bottom End Crank. Pricing accordingly. The sled came from a friends relative who passed away and it sat inside barn for the past 10 years without running. When I took the cylinders off there was a very small amount of debris from sitting in bottom end so flushed it with kerosene and marvel mystery oil, after rinsing out brake clean has slight squeak all rod bearings are tight have up down play motor spins over smooth, think its just dry me flushing this is why I m listing as parts or not working because 100% sure what.

Items are being sold AS IS. I got it running enough to see ran but the cylinders were low on compression due stuck piston rings so decided part out. Crank case and crank came from a running sled. The crank even as a core if it happens to be bad with the cases is worth what I m asking.

Comes with stater, flywheel, water pump, oil pump.
