Ukuguqulwa kokugoba kwe-Crankshaft: Iphutha lokuphuma kwe-radial akufanele lidlule u-0.04~0.06mm. Ijenali ye-Crankshaft: Iphutha eliyindilinga nesilinda ngokuvamile alidluli u-0.01~0.0125mm.

(1) Khetha imakromitha yangaphandle enobubanzi obufanele ngokuya ngejenali ye-crankshaft

(2) Kala inani lokuguga kujenali eyinhloko ye-crankshaft kanye nejenali yenduku yokuxhuma nge-micrometer yangaphandle ngokomthetho wokuguga, futhi ubale amaphutha ayindilinga kanye nesilinda. Qala ngokukala kuzo zombili izinhlangothi zembobo kawoyela yejenali, bese ukhetha u-90° ukuze ukale futhi. Izigaba ezimbili zikhethwa kujenali ngayinye, futhi isigaba ngasinye sikhethwa cishe ku-1/3 wobude bejenali.

(3) Imifantu ephambanayo ayivunyelwe phezu kwejenali ye-crankshaft. Ngokuqhekeka okuphambene, uma ukujula kungaphakathi kosayizi wokulungisa ijenali, kungenziwa phansi ngokugaya, ngaphandle kwalokho kufanele kuchithwe.

(4) Uma iphutha eliyindilinga nesilinda lika-crankshaft wenjini lingaphezu kuka-0.025mm, kufanele igaywe futhi ilungiswe ngokosayizi wokukhanda. 3. Ukulungiswa kwejenali ye-crankshaft yezinjini zezimoto ze-Santana kanye ne-Jetta kuhlukaniswe ngamaleveli amathathu osayizi wokukhanda, ngezinga elilodwa ngo-0.25mm.

(5) Impahla ye-crankshaft ihlukile, futhi izidingo zokusebenza zihlukile ngesikhathi sokulungiswa komshini obandayo. Qaphela ukuvimbela i-crankshaft ukuthi ingaqhekeki noma imifantu emisha.

(6) Naka ukuhlukanisa ubudlelwano phakathi kwephutha le-radial circle runout yejenali, iphutha lokuqondisa kwe-axis ye-crankshaft, kanye nokugoba.

(7) Lapho ukala usayizi wejenali ye-crankshaft, amaphutha ayindilinga kanye nesilinda, kufanele inyakaziswe ngembobo kawoyela.
