Well done, very professional presentation.
I'd be very keen to buy one from you. Hubby's Koelos has the same issue. Have been told the replacement motor runs at $1500 and would need to come up from Melbourne as the Renault parts warehouses in Brisbane and Sydney have both gone under with the floods. Getting pretty desperate as it's a little wet here at the moment and I'm having to Uber him everywhere as his wipers don't work! Couldn't find the listing on eBay nor did I see the link in the comments of the youtube video - would you mind posting the link? Thanks!Thanks schlitzaugen, yeah ill keep you up to date with how it goes.
Regarding the difficulty to change the gear, i made a little youtube video to show people how i did it because it does seem a bit daunting. The link is in the ebay item description too
Yeah i understand your predicament about machining new gears each time, it does make it hard to make it worthwhile.
I went with a high strength nylon with a sls machine, its pretty much the best 3D print you can get in australia so if it doesnt do the job im not sure what will.
Maybe after a year of having the gear in service ill pull it out, take some photos of it and post here. Im keen to see how it wears, when i looked after 6 months it looked fine.
My 3d printed one (that I made) ended up failing and I went with this. This has been a solid replacement.I found the gear on AliExpress that is very much an OEM and is exactly the same as the one in my wiper motor, I've used this site before and it's quite safe: https://www.aliexpress.com/item/1005003931952490.html
