4.INSTALL GENERATOR COIL ASSEMBLY
Temporarily install the generator coil assembly to the generator drive end frame with the 4 through bolts.
Because the generator coil assembly must be installed with a press after the through bolts have first been temporarily tightened, do not attempt to install the generator coil assembly by tightening the through bolts only.
| *a | 21 mm Deep Socket Wrench |
Using a 21 mm deep socket wrench and press, slowly press in the generator coil assembly.
Tighten the 4 through bolts.
