Is there a trick to getting he motor shaft into the drive part of the motor? I separated the two parts of the motor easily, but getting them back together just isn't happening. The parts hang up on the shaft/drive gear about 1/4 inch short of the two parts being fully together. Do I need to turn the outer portion of the drive gear (the part that meshes with the regulator)?

It's listed for some Mercedes sedans from the '90's, but it looks nearly identical to the Porsche motor, including the right number of teeth on the gear. And it's only $65.
Upon closer inspection, the castings are not identical. The mounting holes in the gear case (attaching the assembly to the window regulator) are taller in the replacement motor, and the male plug is on the wrong side of the motor. So I merely switched the actual motor from the newer unit to the old stock gearcase. Perfect fit, and the pinion gear turns smoothly.
The irony fixing the slow, struggling window occurs because the replacement motor is not as fast as the stock unit. Now I'm not even sure that this replacement motor is a genuine Bosch product versus a Chinese knock-off. But it's running smoothly, and at a third the cost of the real deal, I can live with a slightly slower but healthy and smoothly functional power window. I was satisfied enough with the passenger window motor fix that I bought another motor to prophylactically replace the driver's side as well. |
