Kho thiab hloov cov bushings

xoob bushing qhia tau hais tias muaj qib siab hnav ntawm sab hauv ntawm lub camshaft. Txhawm rau kho qhov sib txawv hauv cov bushingsbearing caj dab yog regrinded, qhov loj ntawm lub tom kawg yuav tsum tau txo los ntawm tsis ntau tshaj 0.75 hli. Cov bushings yog hloov los ntawm nias lawv mus rau hauv ib tug yav tas los ntxuav qhov nyob rau hauv lub tog raj kheej taub hau. Tsis txhob hnov qab tias lub tes tsho xa khoom tau teeb tsa ua ntej qhov no, nws yog tsim los muab qee qhov protrusion ntawm qhov kawg ntawm lub tes tsho.

Camshaft hloov

Lub camshaft tau hloov pauv vim qhov ua yuam kev tseem ceeb hauv kev ua haujlwm ntawm lub axis pusher. Txhawm rau hloov lub camshaft tag nrho, koj yuav tsum tshem tawm tag nrho lub cev muaj zog, radiator thiab pem hauv ntej ntawm lub cav. Kev kho-nws-koj tus kheej MAZ yog ib qho kev ua haujlwm nyuaj, tab sis qhov kev ua haujlwm no yuav luag ua tsis tau ib leeg, yog li nws pom zoo kom hu rau cov koom haum tshwj xeeb.

Kev daws teeb meem kev lag luam

Txhim kho qhov chaw kuaj xyuas yog ib qho ntawm cov haujlwm uas suav nrog kev kho dua tshiab ntawm MAZ thiab ua tiav tshwj xeeb ntawm cov cuab yeej tshwj xeeb. Ua li no, nws yog ib qho tsim nyog yuav tsum tau disassemble lub gearbox kom tiav, txheeb xyuas cov khoom tsis raug thiab qhov chaw thiab ua tiav lawv cov kev kuaj mob (nrog rau kev kho thiab kho dua tshiab) thiab / lossis hloov. Tab sis nws tsim nyog nco ntsoov tias tsuas yog lub crankcase thiab npog yuav raug kho dua tshiab, tag nrho lwm qhov chaw raug hloov nrog cov tshiab.

Crankcase kho

Kev kho dua tshiab ntawm lub crankcase yog ua thaum hnav cov kabmob thiab cov pins thiab yog tias cov xov puas lawm. Thaum kho, bushings raug ntsia. Ua li no, lub qhov yog dhuav mus rau ib txoj kab uas hla ntawm 15.5 cm, thiab lub undercut yog 3 hli loj nyob rau hauv.diam.

Hauv qhov no, yuav tsum tau ua raws li cov xwm txheej hauv qab no:

• depth - 2.5mm;
• bushings raug nias rau hauv cov khoom tiav;
• nro tsis tshaj 0.15mm;
• qhov yog qhov dhuav linearly.

Xov xwm kho dua tshiab tshwm sim hauv qhov kev txiav txim no:

1. Drilling nrog ib txoj kab uas hla ntawm 17.1 hli yog ua thiab threading yog ua.
2. Screwing cov screws nrog kua nplaum.
3. Kev xa tawm.

Kho cov kabmob

Ua rau cov kab nrib pleb, kev puas tsuaj rau qhov kawg thiab hnav lub qhov. Yog tias pom muaj qhov tawg ntawm cov yeeb nkab, qhov deformed seem raug txiav tawm.
