Krok 1: Potvr\u010fte p\u00f4vodn\u00fd k\u00f3d prevodovky<\/h3>\n

N\u00e1jdite identifika\u010dn\u00fd \u0161t\u00edtok na existuj\u00facej prevodovke. K\u00f3d Comer T-311J by mal by\u0165 vyrazen\u00fd alebo vytla\u010den\u00fd na telese. Ak je \u0161t\u00edtok po\u0161koden\u00fd alebo ne\u010ditate\u013en\u00fd, zmerajte rozmery hriade\u013ea: vstupn\u00fd hriade\u013e X mus\u00ed ma\u0165 1-3\/8 palca so 6 dr\u00e1\u017ekami (profil Z6) a v\u00fdstupn\u00fd hriade\u013e Z mus\u00ed ma\u0165 toleranciu H7 33 mm.

Krok 2: Overenie smeru vo\u013enobehu<\/h3>\n

Vo\u013enobe\u017eka T-311J sa ot\u00e1\u010da iba v jednom smere \u2013 funguje ako akceler\u00e1tor (zvy\u0161ovanie r\u00fdchlosti), ke\u010f sa vstupn\u00fd hriade\u013e ot\u00e1\u010da v ur\u010denom smere, a vo\u013enobe\u017eka sa odpoj\u00ed, ke\u010f sa smer zmen\u00ed. Pred in\u0161tal\u00e1ciou overte, \u010di smer zapojenia vo\u013enobe\u017eky zodpoved\u00e1 ot\u00e1\u010daniu rotora va\u0161ej kosa\u010dky.

Krok 3: Zodpovedaj\u00face po\u017eiadavky na nap\u00e1janie<\/h3>\n

Model T-311J m\u00e1 maxim\u00e1lny vstupn\u00fd v\u00fdkon 50 kon\u00ed (36,8 kW).

Zmerajte rozmiestnenie mont\u00e1\u017enych skrutiek na sedle skrine prevodovky kosa\u010dky.

Ak sa rozmiestnenie skrutiek nezhoduje, prevodovka je ur\u010den\u00e1 pre in\u00fd model kosa\u010dky bez oh\u013eadu na kompatibilitu hriade\u013ea. Skontrolujte tie\u017e h\u013abku skrine prevodovky \u2013 r\u00e1m kosa\u010dky poskytuje \u0161pecifick\u00fa h\u013abku vrecka pre prevodovku a nezodpovedaj\u00faca h\u013abka skrine br\u00e1ni spr\u00e1vnemu usadeniu alebo vytv\u00e1ra probl\u00e9my s v\u00f4\u013eou s hriade\u013eom rotora.<\/p>\n
