I have a new timing-belt and tensioner installed in a K7m engine(renault/nissan).
Part of the process is to rotate the engine manually from the crank bolt, to ensure the markings still align as before.
I noticed there is a change in position of the tensioner-tooth i.e. just as I was aboit to put back the covers followed by the crank-pulley.
Is this a sign I have done something wrong?
(I have left the spark-plugs in, for this job)
If you've followed the directions as listed in this pdf, you should have no issues. There is nothing there which states the alignment tabs on the tensioner have anything to do with the timing and is not something you need to check.
- Fit the tension gauge (mot. 1715)
- Turn the tensioner pulley anti-clockwise
- Use the special tool (mot. 1135-01)
- The tension is set when the tension gauge indicates a value of: (160 ± 10 Hz)
- Tighten the tensioner pulley nut (50 Nm)
- Turn the engine 2 rotations by hand
- Check that the locking pin can be inserted and removed (mot. 1489)
- Fit the tensioning tool (mot. 1501)
- Use a torque wrench to adjust the timing belt tension (10 Nm)
- Remove the tensioning tool
- Check the tension with a tension gauge (mot. 1715)
- The tension is set when the tension gauge indicates a value of: (160 ± 10 Hz)
- Repeat the procedure if required
