Bedah mesin diesel MWM tbd440-8k-1030kw

pada dasarnya mesin bensin/diesel baik kapasitas besar/kecil memakai matrial dan komponen nyaris sama.yang dimaksud bedah mesin adalah pengenalan:data teknis,data komponen/parts,data ukur,data torsi bolt,data clearances.yang berguna untuk menentukan laik masing2 komponen
sebagai contoh kita buka data mwm 440.....
