(1) Hubi oo hagaajiso nadiifinta dhidibka
Markaad hubinayso nadiifinta axial ee mishiinka u adeegsata flange riixista ee meelaynta axial, geli cabirka dareenka inta u dhaxaysa wejiga dhamaadka hore ee joornaalka ugu horreeya ee kamarad kaamarada ama inta u dhaxaysa wejiga dhamaadka xarunta qalabka wakhtiga iyo garabka riixida. Dhumucda cabbirka dareemaha ayaa ah nadiifinta dhidibka ee kamarad-camsha. Guud ahaan waa 0.10mm, oo leh xadka ugu badan ee 0.25mm. Haddii nadiifintu aysan buuxin shuruudaha, waxaa lagu hagaajin karaa iyadoo la kordhinayo ama la dhimayo dhumucda garabka riixida.

(2)Kormeerka iyo hagaajinta qaloocinta camshaft
Qallooca qalooca ee kamaradda cambarka waxaa lagu cabbiraa qaladka radial runout ee joornaalka dhexe ee camshaft ilaa joornaalada labada daraf. Habka kormeerka ayaa lagu muujiyay shaxanka. Ku rid camshaft-ka birta-qaababka V, iyo birta-qaabka leh ee V-qaabeeya iyo tilmaame garaaca saxanka fidsan, si xidhiidhka tusaha garaaca uu xidhiidh toos ah la yeesho joornaalka dhexe ee camshaft. U rog camshaft-ka oo u fiirso kala duwanaanshaha lulida ee cirbadda tusaha garaaca, taas oo ah heerka foorarsiga ee shafka. Ka dib kormeerka la dhammeeyo, barbar dhig natiijooyinka baadhista iyo qiimaha caadiga ah si loo go'aamiyo in la dayactirayo ama la bedelayo.

(3) Alaabta kale ee dayactirka camshaft
1) Kormeerka joornaalka shaft journal keyway: Diyaarada summeerka ee joornaalka marshada shaft keyway waa in guud ahaan la jaan qaada diyaarada summeedka ee wiishka ugu badan ee qaadashada dhululubada kowaad iyo kamaradaha qiiqa. Xiritaankeedu wuxuu bedeli doonaa wakhtiga waalka. Haddii dariiqa furaha la xidho, waxa dib loo furi karaa alxanka korkiisa ama waxa lagu furi karaa meel cusub.
2) Xirashada ugu badan ee bamka batroolka wadista giraangiraha eccentric: Xirashada ugu badan ee shaagagga korantada ee bamka shidaalka guud ahaan waa 1mm. Haddii ay dhaafto xadkan, camshaft-ka waa in la beddelaa.

Qiimaha qulqulka dhexroorka: heerka - 0.01 ~ 0.03 mm, xadka - 0.05 ~ 0.10 mm.
3) Kormeerka iyo hagaajinta xidhashada kamarada
Marka qiimaha dhimista ugu badan ee kamaradu ka weyn tahay 0.40mm ama xidhashada wadarta ee dusha kamaradu ka badato 0.80mm, kamarad waa in la bedelaa; marka xidhashada isugeynta ee dusha kamaradu ay ka yar tahay 0.80mm, kamaradku waxa lagu dul dhigi karaa furimaha kaamerada.
Si kastaba ha ahaatee, kamaradaha mashiinka gawaarida casriga ah ee kamaradaha gawaarida waa dhammaan noocyada toosan ee la isku daray. Sababo la xiriira saxnaanta hab-socodka aadka u sarreeya iyo qiimaha dayactirka ee sarreeya, hadda aad bay u yar tahay in la dayactiro, iyo shafka-cambaarta guud ahaan waa la beddelay.

4) Kormeerka iyo dayactirka joornaalada camshaft iyo biraha
① Kormeerka joornaalka camshaft iyo xajinta: Isticmaal mikrometer si aad u cabbirto khaladka wareega iyo khaladka cylindriality ee joornaalka camshaft. Khaladka wareega ee joornaalka camshaft waa inuusan ka weynaan 0.015mm, iyo qaladka coaxial ee joornaal kasta waa inuusan dhaafin 0.05mm. Haddii kale, waa in la hagaajiyo sida uu qabo taliyaha.
② Kormeerka xajinta kamarada: Marka nadiifinta u dhigma ee xajinta kamaradadu ay dhaafto xadka isticmaalka, waa in la beddelo sidh cusub.
