1940 windshield wiper motor questions
Posted by Joe Santana On 2011/5/9 15:16:54
My vacuum wiper motor quit too many years ago to say. I think the crusty one I have is it, but not sure.
Sometime 50 years ago I replaced it with a bigger (better one) and modified the bell crank so it would work, sort of. I had to use spacers and the inlet pipe had to be bent so tight to avoid the air vent mechanism, it's a wonder any air got through. It did. It worked. It would disengage with the knob.
But now everything has to be perfect and as original as possible and practical.
So I'm trying to figure out:
1. If the old crusty one I have (with no bell crank) is the original one.
2. If I have no bell crank, how can I find one, make one? That way I would have the old one rebuilt.
3. If I can't find a NOS one (I'm told these must be rebuilt anyway) or a rebuilt one, I could use an electric one.
4. I have a 1940 electric one with all the assembly drivers and mounts out of a Packard 110, but I don't know if it can be installed in a 160. Are the distances to the mounting holes the same as a 110?
According to the Wiperman, Rob Ficken, his Trico book says there were no vacuum motors made for Super 8s, which I know is incorrect. He has one NOS vacuum motor which he thought was right for my car, but when he checked the book, it didn't list Super 8s.
According to my parts book:
The Packard part number for my wiper motor is 331919 or 325861(older number) which is a vacuum motor.
This is the same motor used on the
1938 body styles: 1172, 1174, 1182, 1184, 1185, 1188, 1189, 1190, 1191, 1192, 1194, 1195, 1197, 1198, 1199
1939 body style: 1270, 1271, 1272,1275,1277, 1279, 1282, 1284, 1285, 1289, 12,90, 1291, 1292, 1295,1297, 1299
1940 body styles: (1803, 1804, 1805 chassis only...NOT 1800 or 1801 which had electric motors) 1332, 1342, 1350, 1351, 1356, 1362, 1370, 1371,1372,1375, 1377 (MY BODY STYLE), 1378, 1379
But of course, Trico numbers aren't given.
I wrote to Max Merritt and to Trico in hopes of getting additional info.
And, Rob told me the same Trico motor cores were used on many cars, but the bell cranks were different.
Attached are photos of the old crusty one that I think is the original. The one I modified, turns out, was out of a 48 Chevy truck.
Also I don't know where to look on the motor and/or bell crank for the number when I do find out what it is.
Any help, much appreciated. I downloaded the electric wiper motor pdf just in case I need to do that. And I'll have another set of mounts to chrome. The vacuum ones are in already.
