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.
