1.2 Assembly of wheel hub
(1) Fill the chamber of wheel hub with lithium base grease about 100 cc, then fit the
hub on the shaft.
(2) Screw down the adjusting nut with a torque for about 1kg.m and then loosen it for
1/2 turn.
(3) Put the spring balance up on the bolt to measure the hubs’ starting torque. When
the starting torque arrives to the specified value, lock the nuts slowly.
Starting torque：5 to 15 kg.m
(4) Install the lock plates and lock nuts, after that pull the lock plates up to lock the
bolts.
(5) Wheel assembly
Install the inner rim and gasket inside the outer rim and assemble the outer rim and
inner rim. Pay attention to the following points:

(b) Make the tops of the rim mounting bolts face outside.
(c) Don’t stand near the tyre when inflating air.
(d) When the tyre pressure reaches 98KPa (1kgf/cm
2
), knock the tyre lightly to make
the inner tyre and gasket into the rim.
