FRONT

The front wiper arms are designed to mechanically transmit the motion from the wiper pivots to the wiper blades. The wiper arm must be properly indexed to the wiper pivot in order to maintain the proper wiper blade travel on the glass. The combination of the drive link, articulating link, wiper arm pivot end, the drone pivot and the wiper module bracket creates a four link system that articulates the wiping action of the right wiper arm to effectively clear a larger area of the windshield glass.

The tapered mounting hole in the left wiper arm pivot end or in the right wiper arm links interlock with the serrations on the tapered outer circumference of the wiper pivot shafts and the drone pivot, allowing positive engagement and finite adjustment of these connections. The mounting nuts lock the wiper arms to the threaded studs of the pivot shafts. The spring-loaded wiper arm hinge controls the down-force applied through the tip of the wiper arm to the wiper blade on the glass. The hook formation on the tip of the wiper arm provides a cradle for securing and latching the wiper blade pivot block to the wiper arm.
