2. Mount the anchor on the prisms and measure the runout of the collector.
- The maximum allowable radial runout of the collector is 0.05 mm
If the runout exceeds the specified value, then machine the manifold on a lathe.
3. Using a caliper, measure the manifold diameter.
Nominal manifold diameter:
- starter 0.8 kW - 30 mm
- starters 1.2 and 1.4 kW - 30 mm
- starter 2.2 kW - 35 mm
Minimum allowable collector diameter:
- starter 0.8 kW - 29 mm
- starters 1.2 and 1.4 kW - 29 mm
- starter 2.2 kW - 34 mm
If the collector diameter is less than the minimum allowable, then replace the starter armature.
4. Check that the grooves between the collector lamellas are free of dirt and foreign particles.
Nominal protrusion of collector lamellas:
- starters 0.8, 1.2 and 1.4 kW - 0.6 mm
- starter 2.2 kW - 0.7 mm
The minimum allowable protrusion of the lamellas is 0.2 mm
