Im overhauling my Lucas wiper motor, and on removal of the large spur gear I found a contact sitting in the bottom of the motor case.... Its broken off the switch block assy. Would this switch block be common to anything else? Is it available? Does anyone have a switch block they want to sell?

Im still working on the motor, but the brushes are in top nick, Ive polished up the commutator. I dare say your slow motor could be due to a seizing rotor, the grease inside mine had mostly dried out and gone hard. I highly doubt brushes are available for these anymore.

Ive overhauled my wiper switch also, perhaps you have high resistance in the circut? Check the condition of the wiper motor plug and wiper switch plug and contacts. Whats the condition of the actual wiper rack? Is it stiff?

wiper rack is all cleaned and greased, did it when I put the wiper motor on.

Had a problem with the switch a few weeks ago, had to pull it apart to clean the contacts.
Will pull it apart again cause last time I was in a hurry needed the wipers going to use the car for work.

All plugs and contacts are clean and tight

Well its all finished. Works a treat. The park contact switch is all good. Would someone be able to advise what the sticker should look like that was fitted to the LH Lucas wiper motors, as mine is long gone?

some one else was asking the same thing here only a little while ago.

I think a pic was put up of the sticker and some one had stickers or knew where to get them.

Fixed mine by the way, it was the contact that earths the switch from the internal contacts to the body of the switch.

Only contacted I didnt notice in my hurried first fix.

Brad I was always under the assumption it was HR as well

There are sets of decal sets on ebay for under the bonnet, they're in their ebay shop and they differ from the Rares ones, they are to suit either LH or LX so they do differ, might pay to have a look on there

Oh really?? That's a shame. A forum of any type needs members. Without them it becomes a waste of internet space. These places can become a wealth of knowledge provided people give there input.

even on the fastest speed they are still slow and even seem worse when you jump out of a newer car and in to and older one, same with the head lights, better off sticking a dolphin torch out the window

Well still no luck on the silly little HR sticker for my wiper motor..... You can still see the mark left behind by the original HR sticker. This one that seems readily available is to long..... Why so hard????

I purchased my decals off Graffix Unlimited, and just spoke to Dave overnight (http://www.grafixunlimited.com.au/).
He is going to make up just the basic HR decal as my wiper motor should of had. Brilliant.

Hi Shaun,
I found that the pivot assemblies were seizing up also and making it all too slow. Take them out, lube them and see how you go.
Also check the link arm bushes as they can flog out and you get the dreaded clunk...clunk.....clunk.....clunk...clunk.....clunk.....clunk...clunk.....clunk.....clunk...clunk.....clunk.....clunk!

Hanra,
Rares do a replacement rubber mounting bush.
