Ebitundu by'abasima .

Ebitundu ebikulu eby'ekyuma ekisima mulimu yingini, torque converter, transmission, ne axles za drive mu maaso n'emabega, zonna awamu ezimanyiddwa nga "ebitundu bina ebikulu".

1. Yingini ya Excavator .

Waliwo ppampu ssatu ku torque converter ya excavator: ppampu ekola (supplying pressure oil for lifting and tipping bucket), pampu ya siteeringi (supplying pressure oil for steering), ne ppampu ya sipiidi ekyukakyuka, era emanyiddwa nga travelling pump (supplying pressure oil for the torque converter and gearbox). Ebika ebimu era birina ppampu ya pilot essiddwa ku ppampu ya siteeringi (okugabira woyiro wa puleesa eri omugoba wa vvaalu efugira).

Working hydraulic oil circuit, ttanka ya woyiro ow’amazzi, ppampu ekola, multi-Valiva y’oluguudo, ssiringi esitula ne ssiringi etikkula

3. Circuit ya woyiro etambula: Oil pan ya transmission, ppampu etambula, feed emu ku torque converter ate emu feed ku gear shift valve, transmission clutch

4. Ebikozesebwa mu kuvuga: drive shaft, differential enkulu, nnamuziga-okukendeeza ku ludda.
