DISASSEMBLY/REASSEMBLY
Complete governor assembly - Disassembly
Unscrew the 5 bolts and remove the complete governor assembly (fig. 89-90).
Pay attention to the Oldham union when disassembling and reassembling.
Indeed, when separating the governor and the camshaft supports, it could fall and get lost.
For this reason, when disassembling, we advice you to cover the Oldham union with grease, so that it can act as an adhesive
(fig. 91).
Injection advance variator - Disassembly
Unscrew the fastening bolt of the injection advance variator by using a 14 mm wrench (fig. 92), use puller 981075.421 and rotate
screw B to remove weights (fig. 93-94). While doing this, keep the hexagonal support A locked.
Thermostat - Disassembly
After removing the three M6X25 bolts, disassemble the cover (fig. 86) to reach the thermostatic valve (fig. 87).
To avoid air intake, check the seal ring and replace it if necessary.
The thermostatic valve is to be assembled properly: the bleeding hole should face upwards (fig. 88).
