Centre steering lever
— Use a universal puller to remove centre lever A together with
bearing B.
— Still using a universal puller (see fig. 15) remove bearing C and
disk B along with O-ring A.
— Make sure the centre lever is not warped or damaged, other-
wise replace.
— Carefully examine the bearings turning them slowly, if the
bearing is sound no vibrations, noise nor slight jam-ups shall
be felt.
— Fix centre lever A in a vice if required, and using a light-alloy
hammer and punch remove tapered bearing outside races B,
located in the centre hole (Fig. 14), taking care to remove first
the upper race having smaller diameter by tapping from inside
outward.
— Re-install the centre lever operating in reversed removing
order and accordingly with the following procedure:
- Before assembly carefully lubricate the tapered-roller bear-
ings and related races.
- Before mounting the lower bearing in the axle fit a new disk
and a new O-ring.
- When installing the castellated nut keep to the following
instructions:
• Tighten the nut fully to bed the bearings properly.
• Loosen the nut and tighten again until all plays have
been taken up, then fit a new check pin.
If the hole in the pin is not in the same line as the cut in
the nut, tighten the nut furtherly as long as a new check
pin can be inserted.
- When the reassembly is completed perform pin and bearing
lubrication with the specified grease type just operating the
lubricating nipples placed on the lever.
