SPRING PERCH BALL NO LONGER MADE INTEGRAL WITH PERCH

The rear spring perch ball A-4024 is no longer forged integral with the rear spring perch.

The ball is assembled to the perch by inserting the shank through the upper end of the perch and the end of the shank is then securely riveted in place (see Fig. 845).

This method of construction makes it possible to service the rear spring perch ball without replacing any other part, as when the old ball becomes badly worn, it can be removed and a new spring perch ball installed as shown in Fig. 845.

If an old axle housing on which the perch and ball were made integral is 0. K. for further use, except that the perch ball is badly worn or broken, a new ball can be installed.

This can be done by sawing off the shank of the old ball and drilling it out of the perch. It will then be necessary to ream the upper end of the perch with a special taper reamer and rivet the new perch ball in place .. as previously described. K. R. Wilson is making a taper reamer for this operation.
