Biki ebikwata ku bitundu ebisima mu bujjuvu .

Ka twogere mu bufunze ku bikozesebwa mu kuddaabiriza buli lunaku: Amafuta agasiiga yingini, amafuta g’amazzi (agakozesebwa nga gazzaawo n’okukyusa woyiro), giriisi ya ppini ne slewing bearings (general lithium-based grease), coolant ne antifreeze (okusinziira ku kitundu), battery electrolyte, etc.Mu butuufu, ebintu ebiva mu mafuta bisobola okutwalibwa ng’ekika ky’okusobola, naye nga bitono, n’ebirala. Ebintu ebikozesebwa n’ebikozesebwa ebya bulijjo: okusiba gaasi (o-empeta ne gaasikiti ezigatta), ebiyungo bya payipu eby’enjawulo, ensulo za vvaalu, ebintu ebisengejja amafuta (amafuta n’amazzi ebisengejja amafuta), amannyo ga baketi, ebisiba eby’enjawulo, ebisiba crankshaft, swiiki ya turbocharger, ebisengejja empewo, ebiwujjo ebiwunyiriza, payipu za hydriya ez’amaanyi Liners, hydraulic cylinder piston rings, valve seats, radiator cores, travelling gears load-namuziga ezisitula, track plates, emikono eminene n’entono, ne backet pin shafts, n’ebirala Tewali ku bino bya bbeeyi nnyo. Singa okulongoosa okunene kwetaagibwa, ebitundu nga pilot valves, cylinders, multi-away valves (okuddamu okussaawo valve nnyingi-way basically done), crankshafts, valve cores, etc. zijja kuba zirina okukyusibwa.
