Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / August 2006Windshield washer, Pontiac, 1985, Stationwagon, lining up two halves
I removed the front circuit board with the pump and the pump mechanism. Now when I try to put the repaired piece back over the motor and back plate I've got a real headache. The pinion that fits into the plastic rotation wheel on the front, doesn't line up properly. I made sure I didn't move any of the gearing on either, so what gives? Is there a trick to it? (this is the old style that has the washer pump right on the windshield wiper motor) In article <1156466868.659637.48580@m73g2000cwd.googlegroups.com>, > I removed the front circuit board with the pump and the pump mechanism. > Now when I try to put the repaired piece back over the motor and back [quoted text clipped - 3 lines] > trick to it?

Remove the drill bit when you're done. > In article > <1156466868.659637.48580@m73g2000cwd.googlegroups.com>, [quoted text clipped - 12 lines] > everything in place while you bolt the pump down to the wiper > motor.

Thanks, I'll 'give it a shot' in the morning. > Look at the plastic four lobe cam, one of the lobes will have a > hole in it, there is also a hole in the steel body of the pump > assembly, place a 1/8" drill bit thru both holes to lock > everything in place while you bolt the pump down to the wiper > motor. Remove the drill bit when you're done. Did as you instructed. Worked like a charm.

Remove the drill bit when you're done. Okay, it went back together and the wipers work but an annoying problem that wasn't there before came up. In intermitant mode the wipers don't pause at the bottom of the windshield now, they pause half way across. Could I have still missed the pinion getting put in the cam anyway? Or is this another issue?

Did you have the crank arm off of the drive end of the motor and re-installed 180* off? > Was the wiper motor in the park position when you re-installed > the pump? > Did you have the crank arm off of the drive end of the motor and > re-installed 180* off? Yes. I took the front section (pump, circuit board) off with the wiper motor in the park position and didn't turn on the wipers until I reinstalled it again. No. I didn't take the crank arm off. Is it possible that the pinion is not meshed in the cam in the right spot? The wipers work fine in all modes except intermitent. Intermitent works, but the wipers pause in the wrong place on the winshield. There is a cam activated electrical switch. But I don't know what the switch is for. It could have gotten bent? It's a long piece of thin metal that flexes by a lobe point on the cam. |
