Wiper linkage, aftermarket

Wiper linkage is an aftermarket part for the construction machines. The card gives no part number or machine model; match the linkage to the old one by its mounting points and spindle spacing.

A wiper linkage is a system of levers and joints that turns the wiper motor's rotation into the back-and-forth sweep of the wiper arms. The motor turns the linkage crank, the rods carry the motion to the arm spindles, and the blade wipes the glass through a set angle. When the joints wear, the wiper works with play, hits the edge of the glass, knocks or sticks in one position, and a worn or detached rod stops the wiper altogether. On a machine working in rain, mud and dust, a stopped wiper badly reduces visibility. The linkage comes new. If the wiper motor was straining or blowing its fuse, check the motor too before fitting the new linkage: a seized linkage overloads the motor and wears its gearbox. Replace worn blades along with the linkage.

Specifications

Compatibility

The card gives no original part number. Fit is confirmed by the dimensions and machine model. Other parts are in Cab.

Fitting

After fitting, run the wiper at every speed and check that the blades do not reach the edge of the glass and the linkage does not bind.
