SPECIAL ATTENTION:
The front ball bearing is fixed with a reverse thread ring. Be careful when you disassemble it. Once the ring has been unscrewed, some heat is necessary to remove the bearing.
The rear ball bearing is fixed to the crankshaft with a threaded ring with normal thread. To remove the crankshaft it is necessary to heat the crankcase (120º approx.) until the crankshaft-bearing assembly slides out without forcing the crankshaft.
The rear bearing fixing nut is threaded and fixed with Loctite 270 or similar fastener. Before disassembling the ring, heat the crankshaft to 50 - 90 ºC to facilitate unscrewing.
The rotary valve has 4 holes for connecting to the crankshaft. Pay attention to which hole you mount it. When the piston begins the ascent, the rotay valve should start to open.
