1. Crankshaft hali hehee ole

Ke hehee ka pahu o ka crankshaft, o ka hana a ka enekini ma hope o ka hana ana o ka hewa: e hoopuka ia ka leo kikeke metala ikaika mai ka pahu nui hehee. Inā hoʻoheheʻe ʻia nā bearings a pau, e ʻike ʻia kahi kani "dang, pang". Ke kumu o ka hemahema

(1) ʻAʻole lawa ka ʻaila lubricating, ʻaʻole hiki i ka ʻaila lubricating ke kaomi ma waena o ke kumu a me ka bearing, no laila aia ke kumu a me ka bearing i kahi kūlana semi-maloʻo a maloʻo paha, kahi e piʻi ai ka mahana o ka bearing. a heheʻe ka hui anti-friction.

(2) Hoʻopaʻa ʻia ke ala ʻaila lubricating, ʻohi aila, kānana aila, etc. lepo, a me nā mea ʻē aʻe).

(3) He liʻiliʻi loa ke āpau ma waena o ke kumu a me ka bearing e hana i kahi kiʻi ʻaila; pōkole loa ka bearing a ʻaʻohe mea keakea i ka puka hale bearing, e hoʻohuli i ka bearing i loko o ka puka hale, e ālai ana i ka puka ʻaila ma ka puka hale bearing, a ke hoʻopau i ka hāʻawi ʻana i ka aila lubricating.

(4) ʻAʻole maikaʻi loa ka pōʻai o ka crankshaft journal. I ka wā o ka lubrication, paʻakikī ke hana ʻana i kekahi kiʻi aila no ka mea ʻaʻole i poepoe ka puke pai (he nui ka ʻae ʻana i kekahi manawa a liʻiliʻi kekahi manawa, a he mānoanoa ke kiʻi ʻaila i kekahi manawa a lahilahi kekahi), e hopena i ka lubrication maikaʻi ʻole.

(5) ʻO ka hoʻololi ʻana o ke kino a i ʻole ke kuhi hewa ʻana, a i ʻole ke kulou ʻana o ka crankshaft, a me nā mea ʻē aʻe. mokuʻāina e hoʻoheheʻe i ka bearing.

(6) ʻAʻole lawa ka nui o ka aila ʻaila i loko o ka pā aila a ʻoi aku ka kiʻekiʻe o ka ʻaila ʻaila, a i ʻole e hoʻoheheʻe ʻia ka ʻaila lubricating e ka wai a i ʻole ka ʻaila, a i ʻole ka ʻaila lubricating o ke ʻano haʻahaʻa a i ʻole ka brand inconsistent.

(7) ʻAʻole kūpono ma waena o ke kua o ka bearing a me ka lua noho a i ʻole ka padding keleawe, a me nā mea ʻē aʻe, e hopena i ka hoʻohemo wela.

(8) ʻO ka wikiwiki wikiwiki o ka ʻenekini, e like me ka "wikiwiki" o ka mīkini diesel, ʻo ia kekahi o nā kumu o ke ahi o nā bearings.

Nā hana pale a me ka hoʻoponopono pilikia

(1) Ma mua o ka hoʻokomo ʻana i ka hui ʻenekini, e hoʻolohe i ka hoʻomaʻemaʻe ʻana a me ka nānā ʻana i ke ala ʻaila lubricating (holoi me ka wai kiʻekiʻe a i ʻole ka ea), e hoʻopau i nā ʻōpala e pale ana i ka ʻohi kānana, a hoʻoikaika i ka mālama ʻana i ka kānana koʻikoʻi e pale ai. ʻO ka mea kānana mai ka pipili ʻana a me ka pahu bypass Invalidate.

(2) E nānā ka mea hoʻokele i ka wela o ka ʻenekini a me ke kaomi ʻaila lubricating i kēlā me kēia manawa, a nānā i ka walaʻau ʻino i loko o ka mīkini; e nānā i ka nui a me ka maikaʻi o ka aila lubricating ma mua o ka haʻalele ʻana i ke kaʻa.

(3) E hoʻomaikaʻi i ka maikaʻi o ka mālama ʻana i ka ʻenekini a hoʻoikaika i ka nānā mua ʻana i nā ʻāpana kumu.

(4) ʻO ka ʻoki ʻana o ka pahu crankshaft e hana i ke kikowaena o kēlā me kēia puka hale lawe nui i concentric. I ka hihia o ka liʻiliʻi liʻiliʻi a me ka makemake e hoʻoponopono, hiki ke hoʻohana ʻia ke ʻano ʻōpala o ka hoʻoponopono mua ʻana i ka laina ākea. Pili ka hana ʻoki ʻana i ke koʻokoʻo pili. Ua like like.

2. ʻO ke kumu o ka crankshaft ka halulu

ʻO ka hana o ka ʻenekini ma hope o ka walaʻau ʻana mai ka pahu crankshaft ma muli o ka hopena o ka crankshaft main journal a me ka bearing. Ke heheʻe a hāʻule paha ka pahu nui, e haʻalulu nui ka ʻenekini i ka wā e hoʻohaʻahaʻa nui ʻia ai ka pedal accelerator. Hoʻohana ʻia ka ʻaoʻao nui, a ʻoi aku ka nui o ka radial clearance, a e loaʻa ke kani kaumaha a me ke kani ʻana. ʻO ke kiʻekiʻe o ka wikiwiki o ka mīkini, ʻoi aku ka nui o ke kani, a piʻi ke kani me ka piʻi ʻana o ka ukana. Ke kumu o ka hemahema

(1) Hoʻohana nui ʻia nā bearings a me nā puke pai; ʻAʻole paʻa paʻa a wehe ʻia nā kī paʻa o ka uhi hali, ʻo ia ka mea e ʻoi aku ka nui o ka ʻae like ʻana ma waena o ka crankshaft a me ka bearing, a kani nā mea ʻelua i ka wā e hui ai.

(2) E hehee a hāʻule paha ka mea hao hao; lōʻihi loa ka bearing a nui loa ke keʻakeʻa ʻana, e haki ai ka bearing, a pōkole paha ka bearing e hoʻonoho maikaʻi ʻole ʻia a wehe ʻia i loko o ka lua o ka bearing house, e hui pū ai lāua.

Nā hana pale a me ka hoʻoponopono pilikia

(1) E hoʻomaikaʻi i ka maikaʻi o ka mālama ʻana i ka mīkini. Pono e hoʻopaʻa ʻia nā bolts paʻa o ka uhi hali a paʻa. ʻAʻole pono e lōʻihi a pōkole paha ka bearing e hōʻoia i ka nui o ke keakea.

(2) Pono ka papa o ka lubricant i hoʻohana ʻia, ʻaʻole pono e hoʻohana i ka lubricant haʻahaʻa, a pono e mālama ʻia ka mahana lubricant kūpono a me ke kaomi.

(3) E mālama i kahi kūlana hana maikaʻi o ka ʻōnaehana lubrication, e hoʻololi i ka ʻaila lubricating i ka manawa kūpono, a mālama pinepine i ka kānana aila lubricating.

(4) I ka wā e hoʻokele ai, pono e hoʻolohe ka mea hoʻokele i ka hoʻololi ʻana o ke kaomi ʻaila, a e nānā koke inā loaʻa ka pane kūlohelohe. I ka wā e leo nui ʻia ai ka ʻae ʻana, pono e hoʻoponopono ʻia ka ʻae ʻana. Inā ʻaʻole hiki ke hoʻoponopono ʻia, hiki ke hoʻololi ʻia ka bearing a ʻoki ʻia. Ke ʻoi aku ka nui o ka cylindricity o ka puke pai crankshaft i ka palena lawelawe, pono e poni ʻia ka crankshaft journal a koho hou ʻia ka bearing.
