Moin, with the above engine the crankshaft and the engine side cover heats up very strongly. This does not like the V-belts that sit on a disc at the end of the shaft. Was not the case at the beginning either, only now after approx. 30 operating hours the motor eats the V-belts. I have already changed the two bearings in the lid ( crankshaft bearing and balancing shaft bearing) unfortunately without success. The shaft is also completely without load, therefore without V-belt disc, after approx. 5 min. very hot. I think I’m okay with the conrod camp.
