Kana chero kukanganisa kunowanikwa, shandura zvikamu izvi nezvitsva.

Isa iyo hydraulic booster mune reverse order yekubvisa. Pamberi pekusangana, iyo yekukwesha nzvimbo yecoil, girazi neminwe; zora netsvina yerubricant uye ita shuwa kuti coil nekapu zvinofamba zvakasununguka mudzimba dzavo, pasina kukanganisa.

Rongedza chibvumirano chejoinhi yebhora sezvatsanangurwa pamusoro apa.

Mushure megungano, zora mabhengi ebhora negirizi kuburikidza neoiri 18.

Isa iyo hydraulic booster pamotokari mune reverse order yekubvisa.

Paunenge uchiisa iyo hydraulic booster, simbisa nzungu uchichengetedza mapini zvakasimba uye nekuapukuta nekungwarira.

Kugadziriswa kwe hydraulic booster MAZ

Munguva yekushanda kwemotokari, nyatso tarisa kusungirirwa kwe hydraulic booster kune bracket yemotokari yemotokari, kusungirirwa kwe hydraulic booster pump pulley, nguva nenguva simbisa nzungu dzemugovera bhora.

Tarisa tension yepombi drive bhandi pakugadzirisa kwese. Kushungurudzika kwebhandi kunogadziriswa ne screw 15 (Fig. 96, b). Nekunetseka kwakarurama, kutsauka pakati pebhanhire pasi pesimba re 4 kg kunofanira kunge kuri mukati me10-15 mm. Mushure mekugadzirisa, kiya sikururu ne nut 16.

Nguva nenguva, panguva yakaratidzwa muchati yekuzora, tarisa mwero wemafuta muhydraulic booster pump reservoir, shandura oiri muhydraulic booster system, uye geza sefa reservoir.

Zuva nezuva tarisa kusimba kwekubatana uye zvisimbiso zve hydraulic booster, pombi, pombi uye hoses yehurongwa.

Kune iyo magetsi ekufambisa system, shandisa chete yakachena, yakasefa mafuta sekutsanangurwa kwazvino pachati yekuzora. Dururira mafuta mumudziyo wepombi 10-15 mm pazasi pemucheto wepamusoro wedhishi kuburikidza nefunnel ine mesh yakanaka kaviri. Paunenge uchidira mafuta, usazunza kana kukwizidzira mumudziyo.

Kushandiswa kwemafuta akasvibiswa kunotungamira kukurumidza kupera kwesimba rekutungamira silinda, muparadzi uye zvikamu zvepombi.

Paunenge uchitarisa huwandu hwemafuta mumudziyo wepombi pane imwe neimwe yekugadzirisa (TO-1), mavhiri epamberi emotokari anofanira kuiswa akatwasuka.

Pane imwe neimwe TO-2, bvisa sefa kubva mutangi uye sukurudza. Kana iyo sefa yakavharwa zvakanyanya nemadhipoziti akaomeswa, igeze nependi yemotokari yakatetepa. Usati wabvisa sefa, nyatsochenesa chivharo chetangi remarara.

Paunenge uchichinja mafuta, anoitwa kaviri pagore (nekuchengetedza mwaka), simudza axle yepamberi yemotokari kuitira kuti mavhiri arege kubata pasi.

Kubvisa mafuta kubva muhurongwa:

• bvisa tangi uye, wabvisa chifukidzo, bvisa mafuta;
• bvisa mhuno kubva pakubuda uye kudhonza mapaipi emugovera uye kudhonza mafuta kubva papombi kuburikidza navo;
• zvishoma nezvishoma kushandura flywheel kuruboshwe uye kurudyi kusvikira yamira, bvisa mafuta kubva kune cylinder yesimba.

Mushure mekupedza mafuta, bvisa dhiraivha remagetsi:

• bvisa sefa kubva mutangi, geza sezvatsanangurwa pamusoro;
• nyatsochenesa tangi kubva mukati, kubvisa zvinyorwa zvemafuta akasvibiswa;
• isa sefa yakashambwa mutangi;
• dururira mafuta matsva mutangi kuburikidza nefunnel ine mesh yakapetwa kaviri uye mirira kusvikira ichinyura kuburikidza nemanozzles.

Paunenge uchizadza mafuta matsva, iva nechokwadi chekubvisa zvachose mweya kubva muhurongwa. Nokuda kweizvi, unoda:

• wedzera mafuta kune tangi kune yaunoda nhanho uye usabata sisitimu kwemaminetsi maviri;
• tanga injini uye uite kuti imhanye nekumhanya kwakadzika kwemaminetsi maviri;
• zvishoma nezvishoma shandura chidhiraivho kaviri uchienda kurudyi nekuruboshwe kusvikira maturu emhepo ari mudura amira. Kana zvichidikanwa, wedzera mafuta kusvika pamwero wakaratidzwa pamusoro; dzorera chivharo chetangi uye zvisungo zvayo;
• shandura mavhiri kurudyi nekuruboshwe, uchitarisa kuti haureruki here uye kana mafuta ari kubuda.

Tarisa kucheneswa kwemapini ebhora neinjini ichimhanya pane yega yega TO-1, ichinyatso kutenderedza chidhiraivho chakanangana newachi uye newachi.

Hapafanire kunge paine yekutamba pajoini retsvimbo. Muhinge yechibatiso chine injini yakamira, mutambo haufanire kudarika 4 mm, uye neinjini inomhanya - kusvika 2 mm.
