Tony B Posted June 16, 2014 Share Posted June 16, 2014 Does anyone have an illustration of the vacum set up for Dodge wipers? I can't find any in the manual. I want to check my system put properly. Quote Link to comment Share on other sites More sharing options...
Gordon_M Posted June 17, 2014 Share Posted June 17, 2014 There's only about five bits in that setup Tony? line comes from manifold to screen via swivel joint, splitter to take tube to each motor I was lucky enough to find NOS motors at Chris Muys in Belgium - they make a big difference though still not up to the sort of duty you would expect from a modern system. I think the most effective WW2 wipers were on the Weasel, but Weasel motors really to big to fit on a Dodge, open or closed cab. Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 17, 2014 Author Share Posted June 17, 2014 Thanks Gordon. The fliexble rubber pipes going to the motors, eh, snapped! :red: Otherwise they work OK just a bit disconcerting when they stop as your pulling up a hill. Quote Link to comment Share on other sites More sharing options...
Gordon_M Posted June 17, 2014 Share Posted June 17, 2014 .... and normally in the heavy rain too. One worthwhile mod here is a fuel pump, with a vacuum pump on the top of it, plumbed to a small vacuum tank hidden under the cab, then to the existing wipers. The tank volume keeps the motors working flat out when you have your foot hard down - when normally that causes them to slow to a crawl. I have seen this setup working and it worked really well, but no idea where to get the bits. I think the one I saw came off an old '40s bus, but no idea where you would find a bus driver to ask .....:-X Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted June 17, 2014 Share Posted June 17, 2014 You can get those combined pumps from Chevsofthe40s.com and other classic car parts suppliers. These fuel pumps all look the same but I don't know if the operating arms are different for different engines. Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted June 17, 2014 Share Posted June 17, 2014 You should be able to get one from the vintage power wagons website (don't have the link). Quote Link to comment Share on other sites More sharing options...
paul_bish Posted June 17, 2014 Share Posted June 17, 2014 mine are very erratic, work best when you change gear...you get a high speed burst then Quote Link to comment Share on other sites More sharing options...
Enigma Posted June 17, 2014 Share Posted June 17, 2014 Ours work well, after a while they seem to speed up quite a bit. Offcourse no hills where we live. Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 17, 2014 Author Share Posted June 17, 2014 Gordon, the latest bus wipers are computer operated! ***ing usless but computer operated! They have at least uprated the wiper arms. The old ones were held together by pop rivets and had a habit of shearing and banging on the roof of the car in front. The idea of a vacum resovoir appeals, though possibly 6 volt electric would be the real answer. Trouble is everything else is dates to at least the 1952 rebuild, and it all works! Though I do know some sad souls who restore buses (!) so I'll ask them. Got to think ahead now the Grandaughter could be heading for D-Day 100!

Gordon_M Posted June 18, 2014 Share Posted June 18, 2014 Just keep an eye out for a small vacuum tank then Tony, the one I saw was only about a pint in volume but it appeared to work very well. It was hidden under the passengers side of the firewall and was just bolt on. No idea if this would work just off manifold vacuum - you would certainly need a check / non-return valve between the manifold and the tank though. Computers - hah Quote Link to comment Share on other sites More sharing options...
