The Wiper Room

Let’s start here.

Installing the wiper motor wasn’t a difficult job by any means, but waiting for parts took some time.  They finally arrived, but the rubber standoff that mounts the motor bracket to the bulkhead was unfortunately not available, and mine was pretty well trashed.  I searched some specialty hardware sites such as McMaster-Carr, and found a few possible substitutes, but after reading the 914 forums, it appeared the quickest way forward was fabrication.  No waiting around for parts this time.

.

My solution was a short piece of reinforced rubber fuel line with a larger diameter 8mm threaded rod screwed into the end of the hose, super tight.  To make extra sure it wouldn’t twist out, I dipped it in a little POR-15 before inserting.  It dries rock-hard in 24 hours, is impossible to remove, and yet still remains slightly flexible.

.

Above is a picture of the standoff attached to the wiper motor bracket with a stainless nylock nut.  Once the entire assembly was in place under the cowl, I threaded an 8mm bolt into the other end of the hose from the driver side of the bulkhead, this time using silicon gel.  It’s a long enough bolt that I’m pretty sure it’s not going anywhere.

.

Here’s a happy shot of the wiper motor back in place, with all wire connections restored.  The multitude of photos that I took during the tear-down included closeups of all the wiring, which came in ultra-handy here and everywhere else.  This install is nice and pretty to look at now, but will be completely obscured once the fan housing is mounted.  Yes, I know I said “pretty.”

All the original topside wiper shaft parts were fairly well baked and needed replacement, and there are a surprising number of them. Luckily, Automobile Atlanta’s website has interactive factory parts diagrams which lead you exactly to the needed items.  In this case, the wiper shafts require a different rubber flange and retaining cup washer on both the top and bottom, where they transit the windshield cowling. Then a large chrome ring-nut is tightened down on the upper threads, sandwiching both rubber flanges together for a watertight seal.  That’s a plus when your primary job is removing liquid.

  1. Mr. Brems, your resourcefulness and tenacity never cease to amaze me. I am honored to have you in my life. Thank you.

    • Nice work. Is that just a little shock absorber for the motor so it doesn’t bang around under there?

      I can’t wait to ride around in this bad boy.

      • Yup, basically just a 1.25″ rubber stand-off and vibration damper. If bolted directly to the bulkhead, the sound of the wiper motor would be transmitted through the entire dashboard. The studs on either end are separated by rubber in the middle. The wiper shafts also are isolated from the cowling by rubber seals on top and bottom. Just got my 12v regulated power supply so I can start testing out various electrical components.
