7. Saliida shaabada ee daadato

Mashiinnada cusub waxay badanaa leeyihiin sababaha soo socda:

1. Meesha furitaanka ee giraanta piston looma soo ururin si waafaqsan shuruudaha, qulqulka giraanta piston waa mid halis ah, cylindricity liner cylinderity waa ka baxsan yahay, godka usheeda dhexe iyo godka xuubka dhuuban waa ka baxsan yahay piston Furitaanka giraanta waxay u socotaa isla jihada sababo kala duwan awgood, arrimahani waxay keenaan qiimaha cadaadiska taban ee crankcase si ay u yaraadaan, waxayna keenaan saliidda saliidda ee saliidda crankshaft. Xalku waa in la beddelo qaybaha aan u qalmin iyada oo loo eegayo dhibaatooyinka dhabta ah oo la isugu keeno si waafaqsan shuruudaha.

2. Crankshaft 50_8.os mm qalafsanaanta joornaalka waa weyn yahay, waxaa la safeeyey karaa crankshaft si ay u xaliyaan.

3. Crankshaft oil seal shirka skew, waqtigan waa in dib loo ururiyaa shaabadda saliidda,

Si aad u bannayso; Mararka qaarkood isku-xidhka shaabadda saliidda ayaa aad u gudaha ah, oo qulqulka saliidda shaabadda saliidda ayaa sababi doonta xannibista qayb ka mid ah daloolka soo celinta saliidda ee daboolka usheeda dhexe. Sidaa darteed, marka la ururinayo, shaabadda saliidda crankshaft waa in sidoo kale loo bandhigaa wejiga dhammaadka daboolka dunta 1.5 ~ 2 mm.

4 tayada shaabadda saliidda crankshaft waa liidata, dibnaha ma siman, ma jilicsan, waa in lagu beddelaa shaabad saliid oo tayo wanaagsan leh. Haddii isha shaabadda saliidda maqan tahay ama qaabka uu khaldan yahay, waa in la beddelaa guga wakhtiga ama shaabadda cusub ee saliidda ee isla moodelka ah waa in la beddelaa.

5. Marka la ururinayo shaabadda saliidda, dibnaha shaabadda saliidda waxa lagu xoqaa cidhifka hore ee dariiqa furaha ee furaha fidsan ee furaha daqliga ah ee ku yaal shaabadda, taas oo sidoo kale sababi doonta daadinta shaabadda saliidda. Sidaa darteed, marka aad rakibayso shaabadda saliidda, waxaad marka hore u rogi kartaa jihada furaha ee duuliyaha duulista ee kor u kaca, ku xoq cidhifka hore ee dariiqa furaha daabkii hore, oo kor u qaad shaabadda saliidda adigoo gacanta ku qaadaya marka saliidda rucubka ayaa lagu dhejiyay, si looga fogaado in bushimaha saliidda la xoqo.

6. Kahor intaadan isku dubaridin shaabadda saliidda, shaambada cirifka sida 50-8.o. Saliida ku jirta joornaalka mm waxay sidoo kale sababi kartaa qulqulka shaabada saliidda. Sidaa darteed, ka hor inta aan la ururin shaabadda saliidda crankshaft, waa in aan hubinno in qadaadiicda 50-8.os mm joornaalka uu yahay mid nadiif ah oo aan saliid lahayn.
