Lan-mechanisms windscreen wiper mechanism renewal

[deQuincey]

hi, some time ago i did a partial renewal of this system, only the motor, bit not the rest, so now my concern has been the mechanism

surprised to see the axis in this condition, no rust at all, amazing



i have seen these ones in terrible corroded condition



sand blast, primer and finishing



o

all bits cleaned and greased



sand blasted, anti rust primer, and finishing in satin black



motor does not need anything but wipe with a cloth, new rubber piece

 

[deQuincey]

assembly,

do the nuts



i use three types of grease, vaseline, moly, and red rubber grease from castrol



do not forget the wave washer,



and the sealing ring



this is interesting, here you can see the pieces that form the upper section, the top is an strange ally of dull metal, then a ultrathin washer and the bushing, this one is original from 1971, and is yellow metal, but i have seen onther in plastic, that usually are broken



mock up the pieces carefully, use moly grease for the sliding surfaces



then go to your vise and push



until flush



done, BTW have always a spare, you never know

now to the car

it would bave been nice to assembly everything including motor, but with the old type hose nozzle does not allow to

see the sequence



BTW, i am using a hand made rubber sealing, the one that LuisA proposed is not valid for the e9, the original rubber ring that he found is too big and does not slip into the hole

the nylon washer goes below the outer surface





and done

Sometimes my wipers don't go to the fully down position when turned off...speeds work fine just doesn't go back to stop position...any thoughts?

Try cleaning and retensioning the electrical contacts inside the gearbox so that they make consistent contact with the rotating plate.

@deQuincey ; is the above thread perhaps also a good contender for the diy section?

A pity the pictures are not so nice with the photo bucket thing happening, but they still serve their purpose.
Would you be able to add originals? Or I can add some additional pics with similar meaning of my own restoration.
