After several searches and reading through several threads I open a new topic. Here it is as described above about the timing belt change ! Since I have already pumped enough into the repair of the head and also would like to trust myself to change the timing belt I have read a bit about it. For those who are wondering about timing belts changing head overhaul !? Yes the timing belt came just before 30Tkm new ! BUT ! I have the inner drive shaft cuff ! The fat came unfortunately also to the ZR … the teeth therefore look quite worn out. Since I don’t want to risk anything and fear that the belt will skip or slide through the fat at some point in time, I prefer to take the 200€ for the tooth strap into my hand. The real question is the difficulty of changing and the difference between fixed and adjustable camshaft wheel on the output side. Furthermore, I do not have any fixing possibilities. cjkeit seen egsp. By bolts to secure the gears before twisting. First of all thank you !
