assembly.

3. Using either a mallet (or copper hammer) or a press, install

the needle roller bearing into the yoke so that the snap ring

can be installed in its groove.

The needle roller bearing cannot be installed smoothly if it
is set at an incorrect angle with the flange and excessive
hammering will damage the needle roller bearing.
