Timmyb Posted April 23, 2014 Share Posted April 23, 2014 Just throwing a few ideas around regarding converting an R model over to electric wipers. We have a 1990 model valueliner which came from the factory with electric wipers. Same set up as air except an electric motor instead of air one. But when I talked to my local mack bloke I was told it was different and I'd have to buy the complete system. Over $1000! Found some kits on eBay to convert older cars to electric. Wonder if you could use such a kit on an R model. This one is for a Chevy or GMC truck. $130 roughly. If the swipe/arc of the wiper blade isn't right perhaps redrilling the crank on the spline of the motor will fix that?Any ideas on if this will work or not will be great. Am I missing something?

keg1 Posted April 23, 2014 Share Posted April 23, 2014 I bought a kit from Watts I think it was 750 - 800. It's for my Superliner but I haven't got it on yet. I bought a used motor off Ebay for 50 and then got new arms and blades from Mack for my R . I think I had around 400 in everything. They work great.

Timmyb Posted April 23, 2014 Author Share Posted April 23, 2014 Thanks for that keg1, so that's all you changed? The bloke I spoke to is trying to sell me the linkage arms that go under the dash also. Not sure exactly what the watts kit consists of?

keg1 Posted April 24, 2014 Share Posted April 24, 2014 Yes I had to change linkage also. The kit comes with everything. I was told at my local Mack dealer that the kits aren't available anymore but I'm not sure. They still have everything separately.

2 STICK PUPPY Posted May 18, 2014 Share Posted May 18, 2014 Would a late model R, U or DM electric wiper set up work in my 69 R -685T? Quote Link to comment https://www.bigmacktrucks.com/topic/35498-electric-wipers-on-r-model/#findComment-245922 Share on other sites More sharing options...
2 STICK PUPPY Posted May 25, 2014 Share Posted May 25, 2014 Anyone? Quote Link to comment https://www.bigmacktrucks.com/topic/35498-electric-wipers-on-r-model/#findComment-246780 Share on other sites More sharing options...
j hancock Posted May 25, 2014 Share Posted May 25, 2014 It may require some work because of having the steel dash??? Never tried so can't say one way or the other.
