Manual Intend Stiffmaster - 4
Service:
The bearings of Stiffmaster are NOT out of stainless
steel. This is because this kind of axial bearings is not
available in stainless steel from the industry. There is
salt-water resistant grease everywhere inside the
headset to avoid any wear and corrosion ( I use Liqui
Moly Marine Boat-Grease Ship-Grease 25043). After a
certain time of riding in wet and salty conditions, it can
be necessary to disassemble the unit, to clean it and to
regrease it again.
If so, disassemble the unit and a press out the inner shell
with a
22mm
(smaller than 30mm) nut to push out the
inner shell like shown in the picture. You need any underlayment with an inner diameter
of > 32mm to be able to push out the inner shell.
Disassemble all parts, clean it,
grease it again and put it in again.
The next step is to put in the first
axial-washer onto the blue shell
(don’t forget the black 30x1mm o-
ring around the blue shell),
followed by the axial bearing and
the second axial-washer like shown
in the pic.
Then put the O-ring onto the
bearings in the groove. Make
sure that it does not lay
between the bearing washers.
For this it might be necessary
to put some pressure on the
waser with 3 fingers.
