Windscreen wiper renewal

[karlosantana]

Hello all,
Im doing a lot of work on my car so keep an eye on the tutorials, this is my first.
In this we will be renewing the windscreen motor, this can be because the wipers wont return to centre or stop radomly.
What you will need

In the photo Is

• 16mm Spanner
  "" Socket
  10mm Spanner
  "" Socket
  Ratchet (obviously)
  Ball joint seperator
  Heat (in this case a plow tourch and a jet tourch)
  Windscreen wiper motor and links etc

First of all take the nuts off the two threads on either wiper arm, then push the wiper arms so they're at a positon like the one below


Now heat the thread up until it goes misty, this will make the thread expand then dramatically shrink breaking any corrosion, it's still going to be difficult but it'll make it a bit easier. Next you want to position the boll joint seprator like below so its a bit tight, heat up the thread again and gently tab the top of the ball joint seperator. I would like to say it's easy, it's not, I spent a good 10 minutes doing this occasionally doing the tool up a bit more and twisting, persistance is the trick.

When thats done pull the wiper arms off put them to one side, now silly plastic bits. They're not a headache just awkward, the bit below just unclips tug a bit and it'll go. Later on in the tutorial you'll see the pic for them. On the end of the plastic bits is a tab caught between two peices of metal, unclip the left one first the right one has to "twist" out.

More plastic bits, now they have tabs at the end picture below. I got a spanner and gently prized them off, be carefull they will break if they're abused, you only need to remove the left plastic bit.

Then..... no turning back now!


Now you'll see the wiper motor in question. There's 3 nuts to undo and a bolt


Then Remove and replace! I'm not going to lie, It's a pain to get it back in! just fiddle there is a nack to it, tried to picture it


After it's replaced (I dont think you need a photo of that though , it all need to go back together. It's esier to put together however there are two bit that may cause problems. The meshy plastic bits have clips on that have to be pushed on the bottom on the windscreen. The right handside meshy bit is a REAL pain, I had to "peal" it on so put the tab on first then ease all the clips on. Everything else is in reverse order.
I hope this helps people, is it possible this could be added to the knowlege articles? I have a few more coming to.
Cheers
Kyle

Nicely done I've copied it into the old KB. Just one thing, what did you use to heat the threads up? Fag lighter, blow torch or oxyacetylene cutter?

Edit: Ok, I've seen it now. What's a jet torch?

[karlosantana]

It burns the fuel in a barrel with a constant spark, very efficient hot and you get a nasty shock if you hold the shocker . It hates the cold though, its a geeky equivalent to a blow torch.
Thanks again
