Waa maxay bar kaydka wadaridka
Halkan waxa uu sameeyaa bar kaydka wadaridka ku jira dozer-ka:
Iyada oo la socday qalabka (dozer) bar kaydka wadaridka wuxuu xidhay labada saafid meelaha iyo u oggola in bogie/saafidda yimaado natiijada sarreefaha asagga, kaaga siiya wadarta iyo mid ka mid ah ophanging / articulation.
Wuxuu guud ahaan yahay bar ayaa furin karay siinaysa ("traverse") la dhigay khamir kasta oo yaabba.
Waacidda: ka helaysta saafid frame, kala sharaxaya koronto midig & bidix, ka ilaaliya dhaawacyada tooska aan toosan.
Maxaa yeelay waxaa lagu talagalay korontood weyn iyo isdhexgalka, badanaa loo baahan yahay beddelida ama abuurista custom. 
Waa maxaad fiirsataa markaad beddesho ama iibsan
Haddii aad iibiso bar kaydka cusub (ama beddel) dozer-kaaga, fiiri:
Jira / macaabiilka: Lambar qaata mustaqbalka waa inay muujiyaan shaac iyo mudhul dozer-kaaga. Mid ka mid ah iibiyayaasha ayaa liiska lambar qaata badan oo loogu talagalay mudhul kala duwan (tusaale, Caterpillar mudhul) blog.
Caynabadda iyo xaqiiqsanaanta: Sababtoo ah wajaha la qayb qaata, fulka dhisan oo tayo sare baahimaad. Tusaale ahaan, shirkadda Canton Drop Forge ayaa sheegaya inay abuuraan e-barrooyin cusub ee dhisan ee kala duwan ee mashinka raadkasta.
Xaaladda haddii loo isticmaalo: Qalabka, dhaawaca ama isbedelka muuqda bararka u egowga waxa ay tahay aragti xoog badan. Video wuxuu muujinayaa in la beddelayo meel ka baxsan qalab ku jira dozerka bararka u egowga.
Qalabka saamirka / bushings: Meelaha soo baxa waxay mar walba tuuro maqnaan, sidaa darteed bushings, pinning iyo isku hallaysasho saamirka ay leedahay muhiim addoommada iyo wakhtiga dheer ee isticmaalka.
Qiimaha vs wakhtiga la jebin karo: Sababtoo ah in bararkani la gudbo inay abuurto arrimo weyn ee hoose (isugu dhigista aan saxsan, koronti), waxa uu yar bixinta lacagta si loo helo mid sax ah oo tayo sare.
