I have a 1983 244 turbo that I need to change the timing belt on. I was looking in my Bently manual and I found somethings that make me wonder if I can actually do the job or not. It looks like I need to have Volvo Special tool 5284. Is this something that I can buy at my dealor for a hopefully reasonable price or just find anywhere? Also, "if the old belt has broken,m or if the camshaft sproket must be rotated more than a few degrees to align the timing marks, first turn the crankshaft slightly away from TDC in either direction. This is to guard against piston to valve contact. Sounds a little scarry. Bently also cautioned that" The hole in the crankshaft pulley must engage the guide pin on the crankshaft. If the pulley is installed misaligned, severe engine and accessory damage may occur." This makes me feel like I'm playing with fire. Do you have any advice. I would like to do this and learn, but I don't want to ruin the engine in my car either. I was thinking that this would be a fairly risk free project, but Bently makes it sound like a life and death situation. Please excuse my ignorance and happy bricking!
