Repair notes

 

Full repair description and observations

 

1

On examining the fault there was tw things which could been wrong. The belts are loose or the idler clutch was jammed / blocked

 

 

2

First I changed the belts (which to my opinion they weren’t much loose) but still the new ones were more ‘tight’. This solved the problem, but I don’t excluded that with maniuvring the clutch got freed back to normal. I have this opinion because as I said the original  belts where not that much in a bad shape.
