Windshield wiper motor install - Some questions for the all-knowing 67-72 board - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hopefully the captions are clear enough in these images. Just a few questions in prep to reinstall this or like unit. Thanks for any input.

BTW, I just realized there's a spot in these cowls for a third transmission/wiper? It's on the RH side of the truck.

Per a little research:

1. The rubber mounting pads (I called them washers) are just part of the unit. One of mine has a small crack. It would probably last another 20 years or so, though perhaps I can find something to fit.

2. The fiber element is a gasket (page 57 in assm. manual). That answers the question about the glue as well. On a side note, the assm. manual doesn't seem to show the grommet on the cowl side. It's not much of a grommet, and may be more a spacer. The hole cut into the cowl for these are large and sloppy. At least on mine it is. I'll bet a dealer or two can send me into the right direction for a gasket, and even the "grommet".

3. The rubber seal, which if I recall is very pliable (packed away at the moment). Heck I don't know, maybe there's a replacement. I don't see this in the manual either. All the book mentions is one cemented gasket. I suppose I could just clean it, though it appears to use an adhesive of some sort.

5. For lack of a better term, that's called an transmission arm bracket.

I'm replacing all elect. components on this truck, but the wiper motor and pump were great when I removed them. That said, if anyone knows of great OER replacements, may as well replace those too.

That's for the right hand drive version of these trucks ,everything is 180 of left hand drive

Thanks for the information Grumpy. Thought it might be for RH drive. The two spots on the RH side are close so it threw me off.

Edit: #5 is the crank arm. The end is a clevis pin.
