Restoring Headlight Motors
Posted 16 January 2012 - 05:13 PM
Has anyone removed and completely stripped the headlight motor. I have started to dismantle and clean but cannot figure out how to remove the plastic manual lift dial. Can anyone tell me if the plastic 'turner' is screwed onto the commucator or pressed on and how do you remove. Currently have the bushes out of position and it would be very difficult to replace the commutator without remove this simple plastic component?
What chemicals would you use to clean the components if any and what lubricating fluid if any?

The plastic knob on mine (81 Turbo) are held on by a large flat blade setscrew. Undo this and the knob comes off quite easily (for a 30 year old car!).
I'm cleaning them in low odour kerosene and this seems to also be doing a fairly reasonable job of stripping off the rubberised paint coating and dissolving the old rubber grommet where the wires come out.
Grommet is an easy fix, they are for sale 10 a penny, so no worries there.
My biggest worry is that I do not have what you might consider to be a 'matched pair' as the crank arms are different. I huess that explains the differing response rates for each pod...
When you put them back together a bit of grease on the bearings/gears wouldn't go amiss and of course a lick of nice new paint never seems to make them look any worse!

Nice car Rob!
My plastic nobs do not seem to be held on by anything though.....certainly no visible retainer.
I will try and gently lever it off.

When you take it to bits there is a ball bearing on the end of the main worm shaft - don't loose it!
Also reassembly is a pain as the brushes need to be pulled back with something during assembly, I used cotton thread.
Mine was the thrust bearings all rusted up, cleaned it all up, regreased ti all with silicone grease (Waterproof) and away they both went!

Oz owners don't forget to join the Aussie area of the forum (regional groups) and while you're there add your name to the 'Where the hell are ya' Map locator.

I have a much better understanding now.
Thanks for the pictures Simon.
