A. Pulling Rear Hub Using New Removal and Installation Tool

When pulling the rear hub from the double-row tapered wheel bearings, the pulling effort needed for removal may become excessive. This may result from tolerance variations or corrosion between the tapered wheel bearings and rear hub. In this event, the previously used removal and installation tools (part nos. 140 589 00 51 00 and 201 589 00 61 00), will be ineffective. A new, reinforced removal and installation tool (part no. 140 589 03 61 00) is now available.








Support is provided by 6 bolts (010b, Figure 1) outside the rear hub on a support plate (010d). The removal and reinstallation procedure, in principle, has remained the same and wider applications for the tool are now possible (Figures 1 and 2).

Procedure

1. Remove backing plate and parking brake assembly (see SMS, Job No. 42-0530).

2. Two support plates (010d, Figure 2) are available for:

^ Models 124, 129, 201 and 202.
^ Model 140

3. Pull rear hub from the inner bearing race, making sure that support pins (101b, Figure 2) are properly seated in the centering holes of the support plate (010d).

4. In the event the hub cannot be pulled using the Special Tools, remove the rear knuckle. Press out the hub using a hydraulic press while leaving the removal and installer tool installed. (Hydraulic pressure exceeding 2 tons may occur, Figure 2.)
