Abstract
A method of setting a distance between a first body and a second body in a fuel injector is disclosed. The method includes providing an intermediate body having a first end, a second end and a longitudinal axis, the first end being fixedly connected to the first body and the second end being fixedly connected to the second body. The intermediate body is compressed toward the longitudinal axis. The compression axially elongates the intermediate body, such that the first body is separated from the second body. An apparatus used to set the distance is also disclosed.

A method of setting armature/needle lift in a fuel injector comprising:
- providing a non-magnetic shell having a first end, a second end and a longitudinal axis;
- fixedly connecting the first end with a first subassembly;
- inserting an second subassembly into the second end, the second subassembly engaging the first subassembly;
- fixedly connecting the second subassembly to the non-magnetic shell;
- and
- compressing the non-magnetic shell toward the longitudinal axis and axially elongating the non-magnetic shell, the first subassembly being separated from the second subassembly.
