1: Kūpono nā lama o ka ʻaila a mākou e hoʻopiha ai (e like me ExxonMobil lāua ʻo Shell) a me ka nui o ka hoʻopiha. Ua hana mākou i ke kaupaona pololei a me ka ʻenehana injection grease (e pale aku i ka injection grease like ʻole a me ka hana wela)
2: Ka mālama wela a me ka hoʻololi ʻana o ka ʻili (ka hoʻoholo ʻana i ke kūpaʻa ʻana o ka ʻaʻahu), ka paʻakikī a me ka hohonu o ka papa paʻakikī
ʻO nā kaʻina hana hoʻomehana (e like me ka martensitic a me ka bainitic quenching) e hōʻoia i ka paʻakikī like (HRC 61-65) a me kahi papa paʻakikī hohonu a maikaʻi. Paʻa Ana No nā kūlana hana wela kiʻekiʻe (e like me nā cylinders maloʻo a me nā motika), ua hana mākou i ka mālama hoʻopaʻa kūikawā. ʻAʻole e loli nui ka nui o nā bearings i nā mahana kiʻekiʻe, e pale ana i ka hopu ʻana.
