The weight of the AR34102 engine according to the catalog is 185 kg. The engine number AR34102 is located at the junction of the block and the gearbox. The most common problems here are caused by air leaks through cracks in the hoses, which not only result in fluctuating RPMs but also lead to overheating of the power unit. Weak points of the engine also include valve guides and belt tensioner. The use of cheap oils reduces the lifespan of the turbine and crankshaft bearings. Additionally, there are many issues related to regular oil and coolant leaks.
