I had a very interesting discussion today with Brian Asbury of Canada.
We compared notes on the Owens-Dyneto electric wiper motors with documentation from TM 9-1825B, Willys MB-NAVY-MZ-2 list of parts, Willys M440 W102 Canadian manual (as listed by Colin Stevens in reply to AM #64 p. 60) and Brian's Auto-Lite master catalog.
Owens-Dyneto electric wiper motor
O-D wiper No. Spec. No. Note Willys Part No.
29150 1693 1942 MB
29180 1695 42-45 MB WO-A-5437
29166 ---- 1942 MB (CAN) WO-A-3351
29182 ---- 42-45 MB (CAN)
The WO-A-5437 has a Assy. No. of WO-A-5093 and install No. of WO-A-3482.
The WO-A-3351 has a Assy. No. of WO-A-5436 and install No. of WO-A-3482
The two known Willys numbers above have the same wiring harness, WO-A-5428.
So, after looking at the Canadian and MZ-2 parts lists they have few parts numbers in common, though the parts are actually very similar.
One theory is the early jeeps did not have the suppression capacitor and had two wires thru the cowl with bullet connectors to the wiper motor. Another is the CAN jeeps had a switch on the dash. I don't see how either can be true with the use of the same wire harness.
Anyone with information, photos or an actual part number off the O-D wiper motor they wish to share?
So, anyone with correct electric wipers?
