Disassemble the phonic wheel by loosening the
fixing screws then extracting it, being careful
not to dirty it or knock it.
10.
Loosen the eight M5x20 screws on the front
flange.
To extract the shaft kit, insert two M6x30 (or
longer) flat bit lockscrews in the extraction
bores of the front flange (indicated by the red
arrows).

INFORMATION:
In the first production batch, the flange was
sealed with Loctite 510 and there are no
extraction bores: the extraction operation may
therefore be difficult.
In this case, contact HSD.
11.
Unthread the old shaft kit and insert the new
one, taking care to align the two pressurisation
air passage bores on the front flange and on
the framework.
NB: Lubricate the seats and the ORs as
described in points 3-5 of the procedure for the
model without encoder.
12.
Tighten the M5x20 screws (of a material with a
resistance class of 12.9) on the front flange,
using a tightening torque of 10 Nm
