Hi all,
Fitting a new timing belt kit (INA/Bearmach sprocket, tensioner, idler + Dayco belt).
Previous owner had fitted the modified parts (crank sprocket with belt guides, idler with no guides) but they hadn't modified the case.
According to landrover the case should be modified too - where the idler stud screws into casing a 2mm x 45 Degree chamfer is required.
I am buying a 45 degree countersink and will drill it 2mm deep - but why is this mod required?
Is it for the waist of the new stud to nestle into nicely?
Many thanks from a confused enthusiast
