Wiper arm modification

[RS blu]

The wiper of my 1991 SE  never gone well. When the  its ball is broken I decided to modify it.

First I tried to mount wiper arm from Renault twingo like V8-GT3, but I noticed immediately that it was impossible without changing the support base in the car.

So I used a wiper arm from Toyota aygo -citroen1- peugeot107. This one is longer but the ball is the same. You have to cut it and solder it to the same size like the original arm. You then have to lower the eye, about 4mm, so that it engages well in the screw pin and so you can tighten the bolt that holding the arm. The result is fantastic, you can use a standard wiper blade and it works fine even at high speeds.

I hope I made it to understand (not easy in English for me) anyway I put some photos....I hope it is useful for someone

new arm just shorted , solder and painted

 

 

new arm with original support, you have to lower the arm portion that engages the screw, about 4mm, to tighten the bolt

Interesting.

 

On mine, I made a new ball joint out of aluminum

I had thought about it too, but I could not build it. That's nice! Congratulations

You know... I might want one of those if your willing to make one.

I really want to convert to  modern hook for the wiper. I was in high hopes that someone had done it already.  Anyone consider a modern blade with a non metallic spine?

[Glyn Harper]

I’d love to change my wiper as well if anyone can help out with an adapter or kit or some sort.

Well done,

 

have done this mod to my esprit years ago, also with the 107 arm works great..

i think i got the idea on this forum somewhere many years ago, and copied it.

great minds think alike, (not me but you and  the guy who i copied...!)

You don't need to modify the wiper arm to fit modern flat blades. Some of them are available with a hole to fit a pin. I've been doing so for many years, started with a modified wiper for a Range Rover Sport as proof of concept. Then changed to a PIAA 24" wiper that came with all the necessary adapters.

I think what me and Glyn are after is a bit more. The problem with that pin is the darn wiper likes to cock around many times a second as it slides across the windscreen. The HOOK. which is I think the most popular provides a more stable grip as well as the comfort of knowing the pin isnt just going to fall out. I see your ZIP TIE there. I like it!

I got some audi wipers but I dont have time to fiddle. But if I get some time I will. The audison (Audio processor.) just came in. I finished the carbonfiber dash till I get my led sockets and it still wont be done till summer. I had a bad crazing issue but thats another thread. Also I believe I have to make some stainless hinges. Still have not gotten off my A** and got steel but thats money and another thread.  Actually today I cleaned my room a bit after work. If anyone noticed my photos of my projects arent in the garage :D.

Wifes gonna murder me. :|

 

Either way Yeah anyone wanna chime in. The arm looks great btw. I may do that if nothing else.

I just realized that that is a hook setup... ( FACEPLAM!)

Im retarded...

[cor]

found it!

 

it was this post.

I should also add that pin style wipers are rare as gold in my section of the world... Everyone just replaces the gums..... Yeah... My wiper is held together with hopes and dreams as I needed a gum for that day for inspection.... then it rained and I realized it wasnt falling apart.... Been on there too long... Its almost time to change that gum and lets just say it cant be done twice.

Sorry I am a bit tired I wanted to add: Thank you Cor.

I have also done this same conversion using the same arm.

I've now got a Toyota Yaris wiper arm, so going to see if I can get that to fit with minimal modifications.

[Glyn Harper]

How did you get on Owen? I’d still love to modify my wiper. I don’t have a welder though if I need to cut and shut anything.

Hi  

This winter I made  some  mod for  my Esprit Wiper arm  used  Toyota aygo -citroen1- peugeot107 as some parts. 

Her is the my instruction:

1.   Used C1 wiper and 2 * 5x20mm  and 4 * 5x8mm bolts, 2 * 6mm spacer  and  8mm 5M ball stud bolt

2.   Drilled and puched out 6 nitter from C1   (2 nitter has 6  mm) and later  tap 5 M  secondary  arm and  5M tap the  holes

3.  Made a copy  the mounting plate and (drill 5M hole to fit the ball stud bolt)

4.  Made 2 spacer 6mm x 16mm,  so 5mm bolts fit within  6 mm holes (where  the  wiper blades mounting arm )

5.  Cut the main/secondary  arm  to match  the length (my case around 47cm ) and make 4M  holes each arms  and 5M tap

Need fil down  ball stud bolt to fit the secondary arm 

I hope it will help

[Glyn Harper]

Thanks, that is very useful! So, did you cut down the main arms and then drill new holes to fit them back onto the wiper mechanism part?

Where exactly did you fit the spacers?

[esp88]

See the first picture , When you removed nitte you can see  the  mounting arm has  front 6 mm and back side has 4mm holes, so I used 5mm bolts plus spacer to fit  ( see first /second picture with nitte)

DO not drill to big hole when you removed the nitte  ! 

hope  it will help

 

[Glyn Harper]

Ok, I think I understand, thankyou. What is the word 'nitte' ? I don't know what word. Maybe that is why I do not understand properly.

[esp88]

Sorry I means rivet ( hope it's correct eng.)

[Glyn Harper]

Ah ha! Yes, that makes total sense now!  Thankyou. Rivet is correct.

[esp88]

Remarks:  I also used/made  some mounting plate fo find the right  posion for The Ball stud bolt.

cut the arms set by step  to right position . I used 600mm wiperblads ( I'm not sure org. Size)

[Glyn Harper]

Ok, great. Thankyou. I've started ordering parts, although after my gearbox repair I'm a bit short of funds!

[sailorbob]

There are two types of pantograph wiper arms fitted to the 107 / C1 / Aygo; the main arm of the first generation model (upto 2014) is straight but it's angled on the second generation model (2014 onwards and the 107 was renamed as 108).

[Glyn Harper]

Which version should we buy?

[sailorbob]

The ones Roberto and Yasuo used are the early wiper arms.  The later arms also use aero style wiper blades.

[Glyn Harper]

Right, cheers. The 

Later ones don’t seem to have the circular disc on the pivot mechanism then.

I don''t recall seeing that disc anywhere other than in Yasuo's photos.
