Service & Calibration The engine type normally only leads to a part number of the spare part.
With this spare part number (or manufacturer part number) the dimension
of the glow plug is normally not available and the dimensions of the bore
in the cylinder head cannot be judged. Most of the time it is impossible to
judge the bore diameter DB and DC. Depending on the tolerances of the
glow plug bore it could be necessary to define different adapters for each
bore or to ream the bore to a defined value.
For most requests no engine code or part number is given, although AVL has
manufactured more than 500 different types of glow plug adapters. In addition,
it is possible that due to some of the required changes, the cylinder head has
to be changed slightly as well. Based on this the dimension must be checked
even with known engine type information in the data base.
Why is the information of the engine
type, original part number or manufacturer
code not enough?
