DollyDodge Posted April 14, 2013 Report Share Posted April 14, 2013 (edited) Does anyone have a suggestion where to send the windshield wiper motor to be rebuilt? Or if there is a way to check it to see if it needs to be rebuilt? Last time I turned it on before pulling the motor it moved very slowly. Never the less the connecting wire is shot for sure.

Desotodav Posted April 14, 2013 Report Share Posted April 14, 2013 You are talking electric rather than vacuum aren't you DD? I think that your motors over there are a bit different to ours in Oz. Have you tried opening it up to see if it's just the grease that has gone hard - that seems to be a common problem. 1 Quote Link to comment Share on other sites More sharing options...
B1B Keven Posted April 14, 2013 Report Share Posted April 14, 2013 Check your connections, especially the ground. X's 2 on the "opening it up to see if it's just the grease that has gone hard" advice. 1 Quote Link to comment Share on other sites More sharing options...
Solution Jeff Balazs Posted April 14, 2013 Solution Report Share Posted April 14, 2013 I agree and then try bench testing it. If it still seems like it isn't working right Northwest Starter can repair these. Reasonable and very professional service. Jeff Quote Link to comment Share on other sites More sharing options...
MBF Posted April 14, 2013 Report Share Posted April 14, 2013 If you feel confident, take it apart and clean out/replace the old grease that has hardened , and clean up the commutator and check the brushes. I have one on the shelf if you need it. Both my trucks have vacuum, and they're the closest thing to intermittant wipers you can get! I grew up with them, and like the simplicity.

Jeff Balazs Posted April 14, 2013 Report Share Posted April 14, 2013 I forgot to mention this......but it would probably be a good idea to take your switch apart and clean up the contacts. Doing this made a significant difference in how well mine tested out. Have you got your engine back together? I have missed your postings of late.

doctor dirt Posted April 14, 2013 Report Share Posted April 14, 2013 Dolly I'm sneaking in to see if anyone might know what size grommet is needed for the arms on a wiper motor in a 49 Dodge. I will be looking into a vac boost if mine isn't giving me what I want. I'll let you know if the boost is a help towards better performance. Doc.

Jerry Roberts Posted April 14, 2013 Report Share Posted April 14, 2013 The last one of these that I had apart , not only was the grease solidified but the armature shaft was locked up on both ends . I had to tap the armature out of the housing and lube . Quote Link to comment Share on other sites More sharing options...
DollyDodge Posted April 15, 2013 Author Report Share Posted April 15, 2013 Thanks for all the input. I got brave and took it apart today. The grease is not completely hard, but not far from it. What kind of grease do I replace it with? All the input wires and switch wires are shot, so I will re do them. I am a bit nervous to try the brushes. I don't even know where to start. Does someone have directions? Is there a place to get the rubber gasket that goes between the cab and the wiper arm mount? Regarding the engine, it has bee a trial in patience. After 18 months he got it all apart. Now we are working on the crank, you might remember a while back I asked about cranks. He said he found some, turns out they were cracked so he wants to fix mine, spray weld I think he called it, so that is being done. The whole thing has been frustrating. I keep watching other people's engines get completed, and he keeps poking along on mine. Oh well we are getting closer. Quote Link to comment Share on other sites More sharing options...
Desotodav Posted April 15, 2013 Report Share Posted April 15, 2013 We used poly-coat black graphite grease in my wiper motor as it's a good lubricant that never goes hard. The wires should not be too hard to replace. I had the same feelings with the brushes as you so I gave the wiper motor to my mate to refurbish as he is more knowledgeable in that area. I think that our wiper mounting setup is slightly different to yours - the rubber mount under my wiper arm fitting was just a rubber washer. Glad to hear that your engine is progressing. Mine is out of the 52 truck at present, but should go back in within the week. Things we do hey!!! Quote Link to comment Share on other sites More sharing options...
lugnut123 Posted April 15, 2013 Report Share Posted April 15, 2013 make sure to use bigger wire to carry the extra amps of a 6 volt. when you rewire the moter. Quote Link to comment Share on other sites More sharing options...
Jeff Balazs Posted April 15, 2013 Report Share Posted April 15, 2013 Glad you are finally getting the engine sorted out. I hope that all goes well. I sure miss the adventures of DollyDodge. Jeff Quote Link to comment Share on other sites More sharing options...
DollyDodge Posted April 16, 2013 Author Report Share Posted April 16, 2013 I miss the adventures of DD too. Rhode Island wiring has the wiring for the windshield wiper, o I will order it tomorrow. It is kind of expensive, but there work is really nice, and much better than I do. Thanks for the information on the grease Quote Link to comment Share on other sites More sharing options...
DollyDodge Posted April 29, 2013 Author Report Share Posted April 29, 2013 I worked on the wiper motor this weekend. Took it apart and put new grease in. Put it back together and bench tested as outlined in the manual and it ran like a champ. I was so excited, doesn't take much to make me happy. I cleaned and painted it as well. The wires are being made at RI Wiring and follow the gauges size listed in the manual and they have the old wires to duplicate. Quote Link to comment Share on other sites More sharing options...
Desotodav Posted April 29, 2013 Report Share Posted April 29, 2013 Well done DD. Can you post some pictures when you get it all back together with the wires back in as it might be a good reference to others going down that path. I too can relate to getting 'happy' once a small truck project item is completed. I hope things go as well for you with the crank and engine project. I removed my crank yesterday and sent it off for either a polish or machine. I asked the mechanic about metal spraying and he explained the process for me. He said that my crank wouldn't need it and wondered why I asked. I told him that I had been studying up on the forum and learning as I go, Quote Link to comment Share on other sites More sharing options...
DollyDodge Posted April 30, 2013 Author Report Share Posted April 30, 2013 Desotodav, Yes I will post pictures when it is done. I talked to RI wiring this morning. About $18 to make up the wiring, and get this $16 to ship it. The shipping thing just drives me nuts. It only cost a couple bucks to send the old wiring to them. Oh well, they do outstanding work and better than what I can do myself. Good luck on the crank Quote Link to comment Share on other sites More sharing options...
DollyDodge Posted May 10, 2013 Author Report Share Posted May 10, 2013 Here is a picture of the old and new wiper motor switch wiring. The new stuff is gorgeous. Hope to put it all back together this weekend. 1 Quote Link to comment Share on other sites More sharing options...
