Cummins (onan Generators)

<h3>The Legacy of Cummins Onan Generators</h3> <p>Founded by David W. Onan in 1920, the Onan Corporation built its reputation as a pioneer in portable power generation, initially serving rural America with small electric generating sets. Cummins acquired full ownership of Onan Corporation in 1992, combining Onan's generator expertise with Cummins' engine technology to create a powerhouse in mobile and RV power generation. Today, Cummins Power Generation designs and manufactures power generation products under the trusted Onan brand name, maintaining over a century of innovation in reliable portable power.</p> <p>The Cummins Onan name has become synonymous with dependable off-grid power for recreational vehicles, marine applications, and commercial mobile equipment. These generators are engineered to deliver consistent performance in demanding environments, from remote wilderness camping to mobile work sites. The brand's commitment to quality and durability has made Onan generators the preferred choice for RV enthusiasts and professionals who need fail-safe power solutions away from the electrical grid.</p> <h3>Essential Maintenance Components</h3> <p>Keeping your Cummins Onan generator running at peak performance requires attention to critical fuel system components. High-quality <a href="/7305-cummins-onan-generators-carburetor-repair-kit-5964">carburetor repair kits</a> are essential for maintaining proper fuel mixture and engine efficiency, particularly in generators that may sit idle between uses. Regular carburetor maintenance prevents starting difficulties and ensures smooth operation when you need power most.</p> <p>Climate control is crucial for mobile applications, which is why reliable <a href="/7305-cummins-onan-generators-hvac-cut-off-switch-4209">HVAC cut-off switches</a> play a vital role in generator system protection. These switches prevent compressor damage by monitoring system pressures and temperatures, extending the life of climate control components in RVs and mobile units.</p> <p>The exhaust system deserves equal attention for both performance and noise reduction. Premium <a href="/7305-cummins-onan-generators-exhaust-resonator-5880">exhaust resonators</a> help minimize generator noise while maintaining optimal exhaust flow, addressing one of the key concerns for RV owners who value quiet operation in campground settings. Proper exhaust components also ensure compliance with emissions standards and protect against dangerous exhaust leaks.</p> <h3>Engine Protection and Lubrication</h3> <p>Engine longevity depends on using the correct fluids and maintaining clean filtration systems. Manufacturer-specified <a href="/7305-cummins-onan-generators-engine-oil-12138">engine oil</a> ensures proper lubrication under the unique operating conditions generators face, including extended idle periods, varying load demands, and temperature extremes. Using the right oil formulation protects internal components from wear and prevents sludge buildup that can compromise performance.</p> <p>Equally important are properly functioning <a href="/7305-cummins-onan-generators-engine-oil-filter-cover-5561">engine oil filter covers</a> that seal the filtration system and prevent contamination. These covers must maintain integrity under vibration and thermal cycling common in generator applications. Regular inspection and replacement of filter housing components prevents oil leaks and ensures the filtration system operates as designed, keeping harmful particles from circulating through the engine.</p> <h3>Why Choose Genuine Cummins Onan Parts</h3> <p>Cummins Onan generators are supported by the largest worldwide certified distributor and dealer network in the industry, making it easier to get genuine parts and quality service. Genuine components are engineered specifically for Onan generators, ensuring proper fit, reliable performance, and compatibility with your generator's design specifications. When your power source is critical to your comfort or livelihood, using quality replacement parts maintains the dependability that made Cummins Onan generators an industry standard for over 100 years.</p>

good experience overall. decent website. good price for item purchased. would give 5 stars but I havent yet experienced the shipping and handling time.

Low price, quick shipping & confirmation of order.<br>

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.

website on my computer was tough to navigate

Easy to find parts and order. Great prices. Wide selection of parts for all my cars and trucks!
