Dusha gudaha ee xadhkaha dhululubada waxaa si toos ah u saameeya heerkulka sare iyo gaasta cadaadiska sare, oo had iyo jeer waxay leedahay xawli-xawaaraha sareeyo ee isku jiid jiid leh giraanta piston iyo marada piston.Dusha sare waxay la xiriirtaa biyaha qaboojinta, taasoo keentay cadaadis kulayl daran oo ka hooseeya kala duwanaansho heerkul weyn, oo ay daxaloobaan biyaha qaboojinta.Dareenka dhinaca ee piston-ka ee xadhkaha dhululubada kaliya maaha inay kordhiso khilaafka dusha sare ee gudaha, laakiin sidoo kale waxay keentaa in ay soo laabato.Bisitoonku waxa kale oo uu ku dhuftaa xadhkaha dhululubada marka dhinacu is beddelo.Intaa waxaa dheer, waxay ku xiran tahay horudhac weyn oo rakibid ah.
Cadaadiska gaasku wuxuu soo saaraa diiqad jilicsan oo jilicsan iyo cadaadis cadaadis shucaac ah oo ku yimaada gidaarka dhululubada, waana kan ugu weyn oogada gudaha, kuwaas oo dhamaantood ah cadaadis garaaca oo sarreeya.
Sababo la xiriira cadaadiska kulaylka weyn ee ka dhashay farqiga heerkulka u dhexeeya gudaha iyo dibadda ee gidaarka dhululubada, cadaadis cadaadis ah ayaa ka dhaca dusha gudaha iyo culayska cadaadiska ayaa ka jira dusha qaboojinta ee heerkulka caadiga ah.Si kastaba ha ahaatee, heerkulka aadka u sarreeya, birta u dhow dusha gudaha waxay yeelan doontaa qallafsanaan balaastiig ah, ka dib qaboojinta, culeyska xajinta ayaa ka dhalan doona dusha gudaha.Cadaadiskan yar ee soo noqnoqda ee uu keeno isbeddelada bilawga iyo joojinta waxay keeni doontaa daal alaabta.
Xadhkaha dhululubada waa inuu lahaadaa xoog ku filan, adkeysi iyo iska caabin kulaylka, iyo sidoo kale caabbinta xirashada wanaagsan.Waa in ay jiraan saliidayn iyo qaboojin wanaagsan inta lagu jiro shaqada.
Xadhkaha dhululubo guud ahaan waxa uu ka samaysan yahay bir bir ah oo aan xidhnayn oo ay ku jiraan fosfooraska ama boron, sida HT25-47, HP-CuCrMo, iwm chrome ku dhejinta meelaha saliidda lagu kaydiyo), nitriding ama fosfitinta si loo hagaajiyo caabbinta xirashada.Engegnaanta dusha sare ee xadhkaha dhululubada ayaa inta badan looga baahan yahay in uu ka weyn yahay HB200, oo waxa uu si fiican ula siman yahay engegnaanta giraanta piston.Dusha sare ee gudaha waa inay sidoo kale lahaataa qallafsanaan ku habboon, si ay u yeelato awood kaydin saliid gaar ah iyo waxqabadka socodsiinta.Dusha sare ee gudaha waa inay lahaataa wareeg ku filan iyo saxnaanta cylindricity, iyo taageerada kor u qaadida ee u jeedda xarunta daloolka gudaha waa inay lahaataa saxsanaan sare.
