Warning | Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | |
| Remove | ||
1 | Remove flywheel (2). | ||
| Disassemble | ||
2 | Underlay flywheel (2) | ||
3 | Quickly heat up ring gear (1) with a welding torch and press it off the flywheel (2) with a suitable drift. | ||
| Measure | ||
4 | Measure the inside diameter of the ring gear and flywheel diameter for mounting the ring gear (B) on the flywheel (2) and calculate overlap between ring gear (1) and flywheel (2). | Flywheel dia. | |
Ring gear inner dia. | |||
Overlap between starter ring gear and flywheel | |||
If the largest permissible deviation is exceeded, | |||
| |||
replace flywheel (2). | |||
5 | Rework diameter of the flywheel (2) for mounting the ring gear (1) to the next deviation and select new ring gear (1) with the corresponding deviation. | Flywheel dia. | |
| Assemble | ||
6 | Heat up new ring gear (1). | Measure tightening temperature with a commercially available temperature measuring instrument. | |
Ring gear inner dia. | |||
7 | Lay ring gear (1) onto flywheel (2) up to contact surface. | Allow ring gear (1) to cool for at least 2 min. and then readjust ring gear (1) with brass drift. | |
8 | Attach centerings to the ring gear (1) through the bore diameter (A). | Use a drill bit with a diameter of 11.0 mm. | |
9 | Pre-drill core hole bores for the thread in the ring gear (1). | Use a drill bit with a diameter of 4.5 mm. | |
10 | Drill core hole bores for the thread in the ring gear (1) on the gauge block. | Use a drill bit with a diameter of 8.5 mm. | |
11 | Turn flywheel (2) and chamfer core hole bores in the ring gear (1). | ||
12 | Cut a thread in all core hole bores in the ring gear (1). | Use a thread cutter M10x1.5. | |
| Install | ||
13 | Install flywheel (2). |
