new timing belts

Post by cjeffers9 » Thu Dec 14, 2017 3:56 pm



All right here what I got. 1981 naked wing. Replaced the water pump and finally talked owner in to belts. He open it up and kept saying they look fine. So I bought the belts. Well he took the old ones off. So the question how to get everything lined back up. Read on here someplace that turning the motor with belts off can damage the valves. So how do I do this ?

That's a tough one. If he lined it up at TDC like you're supposed to before he took the belts off, you could just continue on from that point.

If he didn't do that, it's anyone's guess what position the engine is now in, and where the cams are in relation to that. You'll have to pull the valve covers, back the valves off so that they are not being actuated by the cams, set the engine to TDC and reset the cams, then install the belts and then reset the valves.

And don't let him "help" with any other projects.

You can always rotate the engine by hand, if you meet some resistance, then you need to stop and find out why, but rotating by hand will not damage anything, unless after you feel some resistance you go and force the rotation, then you might bend things. As stated you have to realign the crank and camshafts so you will have to rotate them, just do it manually and you should be fine, don’t force it.

Remove the valve covers and loosen the valves as suggested, then you can rotate the engine to get the cams properly timed with the crank. Once you bend a valve it's too late....
