I-Jumbo Mold Shaft iyi-shaft yomhlahlandlela eqondanisa ubakaki wesikhunta neplate yenethiwekhi yemishini yezitini iJumbo MK2, Jumbo MK3 neHyperstat. Kuyinto ebucayi ukuqinisekisa ukuthi isitampu singena ebhokisini lesikhunta, uma selilinganisiwe. Amantongomane amabili shaft ngenhla aqiniswa komunye nomunye ukwakha indlela yokumisa ezocacisa ukuphakama komkhiqizo wezitini owenziwayo. Maphakathi nomugqa kushaft kunentambo evumela ukuthi ipuleti lenkampani yenethiwekhi likhiyele ngokusebenzisa i-cap screw.  QAPHELA:  Uma lesi sikulufo cap sikhululekile, sizoguga imbobo futhi singathembeki sokuphakamisa isitampu ngokufanayo ezinhlangothini zombili - njalo hlola lesi sikulufa ngezikhathi ezithile. 
 
 Ukuwohloka kudabuka ngokuhamba ngomkhono ongezansi; kepha futhi ngezikulufo zamapuleti ezithwala okuxekethile. Amakhefu abucayi avela ezingeni eliphakathi nokusetshenziswa komshini lapho ukudlidlizela kungaphezulu kakhulu kwezidingo ezinconyiwe zokuthola ukuminyana okwanele kwezitini.
 
 Insimbi ye-shaft iwukuyekethisa kokugqokwa okungahambi kahle (kusuka emikhonweni) namandla okuqina (kwezokudlidliza namandla we-torque) kepha yingxenye enamandla kakhulu ebangeni lomshini wokwakha izitini weJumbo.
 
 Faka i-LM grease ukunciphisa amandla okushayisana futhi wandise isikhathi sempilo sale ngxenye.
