Wiper Motor Maintenance

[74 Thing]

What is the typical wiper motor maintenance consist of-mine is starting to make some noise. Also what am I suppose to repair if the motor does not return the wipers to the starting position once it is turned off-they stopp a little after.

if the wipers do not park, then there is likely a broken contact. there is a springy metal contact which controls the parking mechanism and they have a tendency to shear off if the motor is old. the only way to fix this is to replace the contact.

as far as the noise, it is probably the motor needing rebuilding, which usually just means taking it apart, cleaning it and re-greasing the interior mechanisms. it is a fiddly job, but not all that difficult if you are into taking things apart.

74 thing, I think the information that Scott has given you is right on the money. In addition to that you might also be sure that the wire to the park position ( 53a) is intact.

53b high- black and yellow
53e green
53a park- black and white
53 low - black
31 ground- brown
Best of luck. Bob Ingman

bob,

yes, indeed, good call. first things first. check continuity on that black and white wire.

Our rebuilt motors cost 135
but if you mail yours to me, I can fix it based on its need and rebuild it also, usually around 50-75, if its not too screwed up or needing parts.
I can arrange a call ticket if youwant to save on shipping also.

thanks,
Mike

What kind of grease do you use when regreasing the mechanisms?
What specific mechanisms?

[Michael Basso]

I use an all purposre grease,
mainly its the gear under the cover with the wiper shaft.
most times, this is not the main problem with wiper motors. although legend has it that it is.....

In the Thing Stuff DIY article archive there are two very good articvles that cover the wiper motor overhaul and $25 repair. They are 50 cents per article for members of the Type 181 World Wide Registry. The articles are in order of mention, Wiper motor overhaul and $25 Wiper motor repair. K-mann
