Ukulungiswa kweenjini zeemoto kubandakanya ikakhulu ukutshintshwa kweevalvu, iipiston, ii-cylinder liners, okanye ii-cylinder, ii-grinding shafts, njl. Ngokwemigangatho yeendawo zokugcina i-4S, kufuneka zitshintshwe ngezixhobo ezi-4 ezixhasayo, oko kukuthi, iipiston, iiringi zepiston, iivalvu, izitywino zeoyile zevalvu, izikhokelo zevalvu, ii-crankshaft shingles, ii-connecting rod shingles, ii-timing belts, ii-tensioning wheels.
Ukuba itshaneli imiselwe ixesha, kuyimfuneko ukutshintsha itshaneli yexesha, i-tensioner, ukongeza kwi-machining, isilingi, umngxuma wokugaya, umbhobho woxinzelelo olubandayo, kodwa kufuneka kutshintshwe iphakheji yokulungisa, itywina yeoyile engaphambili egobileyo, itywina yeoyile engasemva egobileyo, itywina yeoyile ye-camshaft, ipompo yeoyile, ivalvu yophando olongezelelekileyo, njl.njl., ngamanye amaxesha kufuneka kutshintshwe izixhobo zangaphandle ezifana ne-clutch disc, njl.njl. Ngamafutshane, kuyimfuneko ukutshintsha iindawo ezingaqinisekanga ukuba ziya kulungisa injini ukuqinisekisa ukusebenza kwenjini.
