6.3.2.2. Test in a mode of full braking
| PERFORMANCE ORDER |
| 1. Brake a gear wreath of the stand, include a starter and measure current, pressure and the brake moment which for a starter 35.3708 should be accordingly no more than 550 And, no more than 7,5 In and not less than 13,7 Н·м (1,4 кгс·м). For starter СТ-221 the current should be no more than 500 And, and pressure – no more than 6,5 V.Dlitelnost of starter inclusion should be no more than 5 with. |
| 2. If the brake moment more low, and a current strength above the specified sizes the reason of it can be межвитковое short circuit in a winding статора and anchors or short circuit of windings on weight. |
| 3. If the brake moment and a consumed current strength below specified above sizes oxidation and collector pollution, strong deterioration of brushes or decrease in elasticity of their springs, lag of brushes in щеткодержателях, easing of fastening of conclusions of a winding статора, oxidation or подгорание contact bolts of the traction relay can be the reason. |
| 4. At full braking of a gear wheel the starter anchor should not be turned; if it occurs, is faulty муфта a free wheeling. |
| 5. For elimination of malfunctions disassemble a starter and replace or repair the damaged details. |
