Ob lub qhov square hauv qab bracket thiab lub splined hauv qab bracket tuaj yeem raug tshem tawm thiab rov ua kom zoo li qub uas yuav luag zoo ib yam.Thawj qhov uas yuav tsum tau ua yog tshem tawm cov chainring.Cov hniav nrog ib tug hniav phaj.
Tshem lub crankset kho cov ntsia hlau counterclockwise nrog acrank tshem tawm wrench, ntsia hlau lub tsheb kauj vab crank remover lub cuab tam rau hauv lub crank ntsia hlau qhov, tuav lub crank thaum tig lub kov ntawm lub crank tshem tawm lub cuab tam clockwise (yog hais tias tsis muaj ib tug kov, siv ib tug ciaj ntswj hloov), thiab ces tso cai rau lub tshem tawm cov ncej tig dawb do.Thaum lub crank tau loosened los ntawm nias lub hauv qab bracket, tshem tawm cov chainring los ntawm rub nws downwards.Nyob rau hauv no juncture, koj yuav tsum steer kom meej ntawm cov saw uas yog rub lub pem hauv ntej derailleur.
Ceev faj heev kom tsis txhob ua kom lub crankset puas los yog crank threads thaum koj tshem tawm sab nraud ntawm lub crank.Qhov no tuaj yeem ua tau yooj yim yog tias koj tsis mloog.Thaum tshem tawm British-threaded hauv qab bracket, sab laug thiab txoj cai xov ntawm sab laug thiab sab xis ntawm lub hauv qab bracket yuav tsum tau thim rov qab, thiab cov xov nyob rau sab laug ntawm lub hauv qab bracket yuav tsum yog cov xov pem hauv ntej.Cov xov rau pem hauv ntej ntawm sab laug thiab sab xis ntawm Italian threaded hauv qab bracket yuav tsum tau loosened clockwise, thaum rov qab xov nyob rau sab xis ntawm lub ncej yuav tsum tau loosened counterclockwise.Rov qab xov nyob rau sab xis ntawm lub ncej yuav tsum tau loosened clockwise.
Thaum disassembling, pib los ntawm kev tshem tawm ib qho ntawm sab laug.Thaum koj disassemble nws, ua ntej unscrew nws thiab ces cia nws nyob rau hauv qhov chaw;tsis txhob tshem nws tag nrho.Tig lub ntsia hlau rau ntawm sab xis counterclockwise kom unscrew nws, thiab ces tshem tawm ib txhij ntawm ob sab.Thaum lub installation txheej txheem, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm sab laug thiab sab xis.Feem ntau, sab xis sib haum mus rau lub hauv paus loj dua lub cev, thiab sab xis sib haum mus rau qhov loj dua.Ib sab laug yog qhov me dua ntawm ob.Kev siv cov roj nplua nyeem rau hauv daim duab duab ntawm lub hauv paus ncej yuav ua rau kev ua haujlwm yooj yim dua thiab yuav ua rau nws tsis tshua pom tias cov xov yuav puas.
Thaum txhim kho, pib los ntawm kev muab lub hauv paus ncej nyob rau hauv qhov chaw, ces tig nws counterclockwise kom nruj nws.Tom qab ntawd, muab tso rau sab laug nyob rau hauv qhov chaw, siv lubcrank tshem tawm wrenchtxhawm rau ntsia hlau sab xis mus rau qhov chaw nruab nrab thiab lub dav hlau ntawm lub hauv qab bracket, thiab tom qab ntawd nruj rau sab laug.Tom qab ntawd, muab cov hlua khi rau ntawm txoj hauj lwm ntawm lub hauv qab bracket kom tiv thaiv kom tsis txhob xau, thiab muab cov chainring rov qab rau hauv qab bracket.
Thaum twg raws nraim yuav tsum tau tuav lub qag qhov chaw, ces?Feem ntau, lub hauv paus axis txiav txim siab tias qhov txawv txav tsis zoo ntawm lub suab nrov yog siab heev, thiab vim li ntawd, lub hauv paus axis yuav tsum tau khaws cia.Kev saib xyuas ntawm cov cuab yeej no feem ntau suav nrog ntxiv butter thiab ntxuav cov kabmob sab hauv lossis cov pob uas tuaj yeem muaj.Nyob rau hauv cov kev tshwm sim hais tias cov bearing npas los yog lwm yam dov Cheebtsam tau dhau los thaum hnav thiab tsim kua muag tseem ceeb, koj yuav tsum tau hloov nws.
Ua ntej ua ib qho kev saib xyuas, ua tib zoo tshem tawm cov kabmob ntawm lub hauv paus ncej ntawm lub tsheb kauj vab siv lubtsheb tuam crank puller, thiab tom qab ntawd siv lub ntsej muag ntse kom ua tib zoo nqa cov plua plav npog los ntawm cov kabmob.Saib xyuas kom tsis txhob khawb lossis ua rau cov plua plav npog puas.Nyob rau hauv qhov xwm txheej uas tsuas yog yam uas ploj lawm yog butter, koj muaj kev ywj pheej los koom nrog tam sim ntawd.Nyob rau hauv cov xwm txheej uas pom impurities, xws li roj av lossis roj av tuaj yeem siv los ntxuav nws.Yog tias cov nplhaib sab hauv thiab sab nraud ntawm cov kabmob tau pom tias yog wobbly, qhov no qhia tau hais tias cov kabmob tau mus txog qhov kawg ntawm nws lub neej muaj txiaj ntsig thiab yuav tsum tau hloov.
