lucas wiper motor crossreferences
Hi all y'all. As I complete more things on my car I have arrived at the windshield wipers. The wiper motor and assembly was already installed and working on the car when I got it and appears to be a Lucas DR3 or DR3A of mid 60's vintage.
Problem is it only sweeps about 100 or so degrees, or differently said, from park position on the lower windsheild rubber to just past vertical at its farthest travel. I have checked all my Lucas reference books, but they just give part numbers for the gear wheel referenced to car and year (example : MGB 64-67 , gear p/n 54707145) but no mention of degrees of sweep. Does anyone know what the correct gear wheel p/n or car/year that would give me the "correct" sweep on my Cobra - I'm guessing 150 to 160 degrees of sweep from park to farthest travel. Any info would be appreciated. Greg |
Greg,
I could be wrong, but I don't think the gear controls the sweep of the arms, only the speed. The number of degrees of sweep is controlled by the length of the moment arm, or in other words, the distance of the linkage pivot from the center of the gear. If that distance is adjustable, move the pivot point away from the center of the gear and you increase the travel. Steve |
