It comes as one assembled part, with the crankshaft, flywheel webs and connecting rod together, as shown in the product photos. Easy Life Markets sells it for chainsaw owners and small engine repair shops rebuilding the bottom end of this two-stroke saw.\u003c\/p\u003e\n\n\u003cp\u003eA \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Chainsaw\" target=\"_blank\" rel=\"noopener\"\u003echainsaw\u003c\/a\u003e engine works hard at high revs, and the crankshaft and connecting rod carry all of that load. If a saw has seized, run lean, or been run with too little oil in the fuel, the connecting rod bearings or crankshaft can be damaged.

Pressure and vacuum test the crankcase after assembly to check for air leaks, which can cause a new engine to run lean.\u003c\/p\u003e\n\n\u003ch2\u003ePreventing Another Failure\u003c\/h2\u003e\n\u003cp\u003eMost chainsaw bottom-end failures come from running lean or low on oil. Always mix fuel and two-stroke oil at the ratio your saw's manufacturer specifies, use fresh fuel, keep the air filter clean, and have the carburetor adjusted correctly after the rebuild. Letting the saw warm up before cutting also helps.\u003c\/p\u003e\n\n\u003ch2\u003eA Note on Supplier Specifications\u003c\/h2\u003e\n\u003cp\u003eThe supplier's listing also mentions a power rating and \"aluminum alloy\" material. These figures do not match what is normally expected for this model or for a steel crankshaft, so we have not included them in the specifications above.
