4.1 bush/bearing Removal (Fig.5)

4.1.1 Select a sleeve that will sit square on the bearing/bush

housing and will allow the bush/bearing to be

extracted without interference. Ensure that only the

force end of the sleeve with the U-shape inspection

slot is used to sit on the bush/bearing housing. The

stepped end of the sleeve should be used to locate in

the end plate.

4.1.2 Select a second sleeve that will sit square on the outer

ring of the bearing/bush and will pass through the

bearing/bush housing without interference. Ensure

that only the force end of the sleeve with the U-shape

inspection slot is used to sit on the outer ring of the

bush/bearing. The stepped end of the sleeve should

be used to locate in the end plate.

4.1.3 Remove the nuts and thrust washers and pass the

force screw half way through the bush/bearing centre

hole. Lubricate the force screw before use.

Note! Always use the largest diameter force screw available

that will fit through the centre of the bush/bearing.

4.1.4 Fit the end plates to the stepped ends of the selected

sleeves. Ensure that side-A is only used for 'A' sleeves

and side-B is only used for 'B' sleeves.

4.1.5 Slide the assembled end plates and sleeves over the

force screw and fit the thrust washers and nuts.

Progressively tighten the nuts whilst locating the

sleeves squarely on the bush/bearing housing and the

bush/bearing outer ring. Once the sleeves are square

on the housing and outer ring, tighten the nuts and

check that the thrust washers are centralised in the

end plates.

4.1.6 Using the appropriate size ring spanners for the force

screw nuts, gradually tighten the force screw nuts to

drive the bush/bearing from the housing.

DO NOT use

air tools to operate the force screw nuts.

DO NOT

apply more than 150Nm torque to the force screw

nuts.

4.1.7 Once the bush/bearing has been successfully

removed, clean the components used and return

them to the carry case.

4.2 bush/bearing Installation (Fig.5)

4.2.1 Select the appropriate sized sleeves for the housing

and bush/bearing as described in Section 4.1.

4.2.2 Prior to installing the bush/bearing clean the inside of

the housing with abrasive cloth to ensure that it is free

from debris and corrosion.

4.2.3 Lightly oil the outer ring of the bush/bearing to be

installed and using a hammer, gently tap around the

outer ring of the bush/bearing to locate it into the

housing. Care should be taken to ensure that the

bush/bearing is square to the housing when installing.

Note! Always use the largest diameter force screw available

that will fit through the centre of the bush/bearing.

4.2.4 Lubricate the force screw and assemble the kit as

described in Section 4.1 and as shown in Fig.5. Once

the sleeves are square on the housing and outer ring,

tighten the nuts and check that the thrust washers are

centralised in the end plates.
