Hello,
Having a little trouble loosening the timing chain on my Mazda 2 from 2012… Contrary to title it doesn't have to be totally removed, only loosened.... Sorry about that.
Reason is I need to change the valve buckets. I have the help from an experienced technician, but we still can’t figure it out….The Mazda workshop manual states the following steps:
1)
Remove the drive belt (so two service holes are easy accessible)
2)
Remove the two blind plugs from the service holes
3)
Insert M6 bolt (45-80mm) into the right-side service hole. Leave +- 2mm space from where it contacts the tensioner arm.
4)
Release tension on the timing chain by turning the crankshaft pulley counter clockwise. The M6 bolt should be pressed in.
Problem is nothing really happens with the timing chain when I turn the crankshaft pulley counter clockwise. The timing belt doesn’t seem to loosen at all and the plug doesn’t get pressed in.
Next, the manual also states in a separate note section that I have to insert a precision flat head screwdriver into the left service hole. Then I have to rotate the crankshaft pulley (again???) counterclockwise with the plunger lock released.
The manual is kind of confusing and doesn’t clearly tell me in what order I have to do things. Can someone explain what to do in which order?
Thanks!
