3.3.7.3. Generator

Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight.
2. Designate and disconnect from the generator a wire. On a part of cars for access to the generator it is necessary to remove an air purifier and a stream measuring instrument.
3. Weaken bolts and remove a belt.
4. Turn on and get adjusting and axial bolts and remove the generator.

Installation

PERFORMANCE ORDER
1. If you decided to replace the generator, be convinced that new (or repaired) the generator in accuracy corresponds to the replaced. Pay attention to conclusions – their number, the sizes and a relative positioning should be same, as on the replaced unit. At last, check marking. Marking should be or is stamped on the case, or printed on a label and pasted on the case. Be convinced that numbers on new and replaced units coincide.
2. On many new (or repaired) generators there are no pulleys therefore it is necessary to rearrange a pulley from the replaced unit.
3. Installation is carried out upside-down. Adjust a belt tension.
