Doing a timing belt change (and water pump, and tensioner pulleys). Before removing the old belts, I tried to align all the timing marks. I can get all the marks to line up (on both belts) except the crankshaft sprocket. This sprocket is out (behind) all the other marks by about one tooth.
Two questions?
- Is this normal for a belt of this usage, or was the last installation wrong.
- There are two marks on the crank sprocket, one is a spring roll pin, inserted into the sprocket near the outer edge, this is the one that is one tooth from the fixed timing mark, the other is a small half round notch closer to the center of the sprocket, on a lip, but is about 6 teeth from the fixed timing mark when all the other marks line up. I'm going with the split spring roll pin, unless I hear other wise. No matter how often I tried, I could not get the half round mark to line up with anything else.
The car ran perfectly before the timing belt change. This is just a routine belt change and was only started because the old belt was past due for a change.
Thanks in advance
