As you may know, engines for Soviet tanks was basically from tractors. There is a true story about t-55/62 tanks that was taken by Israelis after Yom Kippur war(1973).In mid-70’s Israel asked Romania to sell Soviet tractors K-700/750.Romanians was very happy to get hard currency and sold few hundred of them. Soviets started to analyze the situation and tried to figure out why Israelis needed their tractors. When conclusion was reached it was too late. There was a need for engines/parts for T models and they are the same.
Not an unusual concept. The GMC 6 cylinder diesel engines used in the M4A2 were truck engines. To get sufficient horse power, two GMC engines were mounted side by side in the engine compartment. It was possible to drive the M4A2 with one engine, but you could not reach much speed that way.
