*Effective immediately after 3-1-24, Powersportsnation will no longer be installing the one-way bearing on centrifugal clutches for Arctic Cat H1 or H2 engines. This will cover the H1 550, 650 and 700 builds as well as the H2 1000 Prowler, Thundercat and Wildcat builds. We continue to see failures on this bearing. Arctic Cat oem removed them from the assemblies in 2014-2015 between both the atv and the utv product lines. We will be using a clutch pack carrier and clutch drum that will accept the one way bearing. It is your choice to go back into the engine and install one. This bearing essentially acts as engine braking and customers who ride in the mountains may want this bearing installed. Due to the high wear of this product and the defects we see involved, we will not warranty failures on this product if you install one and they fail.
Freshly rebuilt Arctic Cat ATV 550 powerplant.
Powersportsnation is now paying $200 for your core. If it has a hole in it, if it has been disassembled or is locked up you will get 50% of this core value. We provide a return label to bring back the core free of charge to you. Please call for the return label.
This engine ships for free but must go FREIGHT. To ship it freight you must have a Commercial Business address to ship it to. The Commercial Business address must have a loading dock or a way to unload the package.
PowerSportsNation Rebuilt Engines.
Our process:
-Engines are completely disassembled. Cases are hot tanked or pressure washed.
-All rebuilt engines include new piston(s) and rings, new gaskets and seals, new timing chain (where applicable), water pump seal kit (if water pump is part of assembly), new oil filter, and new spark plug(s).
-Heads are refreshed or rebuilt (on a Rottler Head Machine SG7MTS) with the valves adjusted. All heads are checked for trueness and surfaced or planed if necessary. All valves, guides and seats are checked and replaced if needed.
-Cylinders are always overbored to the next size or sent off and replated.
-Crankshafts are inspected. If they are not in excellent or near new condition, they are rebuilt or replaced. If automotive style crank and rods are used in the application, all bearings are replaced. Crankshaft roller bearings are replaced where needed.
-Transmissions (where applicable). All parts are visibly inspected or measured for wear. All bearings, shift forks and gears are replaced where needed. Any other worn internals will be replaced where needed.
-Oil pumps are a crucial component in the build. They are all torn down and inspected. If they don’t appear to be near new, they will be rebuilt or replaced.
-Assembly begins after all parts are inspected and the replacement parts are on hand. Each engine is hand built with quality workmanship to insure the longevity of your powerplant. All bolts are torqued to appropriate specs for each engine type.
-The final step in the process here at PSN is to test run your engine. Because of the vast inventory of used parts from our salvage operation we have been able to build test cradles or test rollers. We run 9 out of 10 engines that leave our facility. And are continuing to build towards 100% testing. This helps us catch any issues before they make it to the customer.
-Our warranty, in the event that you have an issue. All Sport quads (Ex: YFZ450 or scrambler) or sport side by sides (Ex: RZR) engines carry a 90-day warranty. All Utility ATV and UTV engines carry a 180-day warranty. The first 90 days of warranty covers parts or exchange and labor (max labor coverage-$500, if installed by a professional shop in the industry). The second 90 days covers parts or exchange only. (Excludes sport quads and sport side by sides)
