Class C 5x9 ;BT2-8735 BB --- Installation Methods 

What does the operator of a machine do when the operator’s machine, located in a remote area away from any sophisticated tools,  needs a bearing replaced? Timken suggests using the following  procedures for installing AP bearings when sophisticated tools  are not available. These methods for installing AP bearings are  valuable ways of saving time and money. Unlike other tapered roller bearing installations where the individual components are installed separately, the complete AP bearing  assembly should be installed at the same time.

Hydraulic RAM Method 

One method of installation utilizes a pressure piston pump and ram  in an arrangement as shown at right. The 445 kilonewton (50 ton) capacity centerhole hydraulic ram is  used for the Class D (5 1⁄2 x 10) bearing

Threaded Rod and Nut Method 

One of the least expensive tooling arrangements for installing our  AP bearing utilizes the tools shown in Fig. 27. The push tube is counterbored to accommodate our T127 thrust  bearing to eliminate much of the friction between the nut face and  the push tube.
