Ebitundu ebikulu: ebiseera ebisinga bikolebwa omubiri gwa vvaalu, omusingi gwa vvaalu, ebisiba (nga O-empeta, ebisiba emimwa, ebisiba ebigatta, n’ebirala), ensulo, n’enkola z’okukola (nga emiggo egy’omu ngalo, silinda ezifuga amazzi, n’ebirala).
Enkola y’okusiba: Okukozesa okukyukakyuka okuwanvuwa kw’ekintu ekisiba okunywerera ddala ku kifo ekisiba, oba okukola ekizibiti ky’ekyuma okuyita mu kusenya okutuufu okw’omusingi gwa vvaalu n’entebe ya vvaalu, okuziyiza amazzi okukulukuta okuva mu bbanga. Ebika ebikulu ebya bulldozer seals mulimu ekimu-angule sealing valves (okuziyiza oil backflow), directional sealing valves (okukyusa obulagirizi bwa circuit ya oil), overflow sealing valves (okutuuka ku control system pressure obutasukka kkomo erya waggulu), brake sealing valves (okufuga okuggulawo n’okuggalawo circuit ya buleeki), n’engeri endala ez’ekikugu n’ebifo eby’okulonda. Enkola y’okuzimba: V-Empeta y’okusiba enkula eyongera ku mutindo gwayo ogw’okusiba ng’eyita mu dizayini y’emimwa mingi, ate ekizibiti ky’amafuta g’amagumba kyesigamye ku magumba ag’ekyuma okulongoosa obutebenkevu bw’okuteeka. Ekiziyiza ky’amafuta ekitengejja kyettanira ensengekera y’empeta ey’ebitundu bibiri okusobola okukwatagana n’embeera z’okukuba ennyo.
Okugumira ebbugumu ne puleesa: Ebisiba ebya bulijjo bitera okusaanira ebbugumu eri wakati wa-40℃~120℃. Ku mbeera ya puleesa eya waggulu-, ensengekera y’okusiba ey’enjawulo erina okulondebwa, gamba ng’empeta ekozesebwa ennyo mu ngeri ya U ng’erina empeta ewanirira mu ssilindala z’amazzi ez’ebyuma ebizimba okutumbula okuziyiza kwa puleesa. Kino kirina amakulu mu makolero .
Okulongoosa Ebyuma Obwesigwa: Ebisiba eby’omutindo ogwa waggulu bisobola okukendeeza ku muwendo gwa bulooka obulemeddwa, gamba nga bulooka ezikozesa okutambuza amazzi mu byuma. Oluvannyuma lw’okulongoosa enkola y’okusiba, obulungi bw’okufulumya bulooka busobola okwongerwako ebitundu 50% bw’ogeraageranya n’ebikozesebwa eby’ennono.

Okutumbula okukyusa mu ggwanga: Shantui n’ebitongole ebirala bikendeezezza ku kwesigama ku bitundu ebiyingizibwa mu ggwanga era ne binyweza ekifo kyabyo eky’okukulembera mu katale ka bulooka z’omunda mu ggwanga nga bayita mu kunoonyereza okwetongodde n’okukulaakulanya tekinologiya ow’okusiba. Ebintu byabwe bibadde bibikka ennimiro eziwera nga road rollers ne excavators.
Okutuukagana n’embeera enzibu ey’okukola: Bulooka eno ekola ku mazzi n’omu mazzi yeettanira dizayini ey’enjawulo ey’okusiba wansi w’amazzi, esobozesa emirimu wansi w’amazzi okuyita mu mifulejje gy’empewo n’enkola ezifuga ewala. Okuziyiza okukulukuta n’okuziyiza puleesa y’ebitundu ebisiba bye bikulu eby’ekikugu.
Obulabe bw’okulemererwa okusiba n’okuddaabiriza .
Ebivaako okulemererwa okutera okubaawo, okukulukuta kw’eddagala: Ebirungo ebigattibwa mu mafuta g’amazzi tebikwatagana na kintu ekisiba, ekivaako okuzimba kwa kapiira oba okukaluba. Okugeza, woyiro wa phosphate hydraulic asobola okwonoona ACM okusiba empeta 4.
Ebyambala eby’ebyuma: Okusikagana okw’ekiseera ekiwanvu okw’ebisiba ebikyukakyuka (dynamic seals) kukungaanya obucaafu, oba okukunya omumwa ogusiba nga guteekebwamu, ekivaako okukulukuta.
Okukaddiwa kw’ebbugumu: Ebisiba byanguyira enjatika mu mbeera ez’ebbugumu eringi-. Okugeza, ebisiba okumpi ne yingini birina okukolebwa mu kintu kya fluororubber ekiyinza okugumira ebbugumu erisukka mu 150℃. Enkola z’okuddaabiriza .
Okukebera Okuteeka mu nkola: Okwoza obucaafu mu kisenge ekisiba, teekako amafuta agakola okukendeeza ku kusikagana, era weewale okukunya ekintu ekisiba 4 n’empenda ezisongovu.
Enzirukanya y’okukyusa buli kiseera: Okusinziira ku bbanga ly’omala ng’okola, kirungi okukebera okwambala kw’omumwa ogusiba amafuta g’amagumba buli ssaawa 1000 n’okukyusa enkola ya hydraulic system seal 5 okutwaliza awamu buli ssaawa 2000.
Okukyusa n’okutereeza embeera z’okukola: Teeka ekibikka ku nfuufu mu mbeera erimu enfuufu, era ogezese obuziyiza bwa puleesa y’amazzi obw’ebitundu ebisiba nga tonnaba kukola mirimu gya mazzi.
