Left light motor repair

Postby C3LOS » Sat 03.06.2017, 20:24

With the MOT due, I thought it best to get round to repairing the left light motor.
After getting the kit from Wayne (Elan M100), and watching there YouTube video (very very helpful), I finally got it sorted.
Sadly the quote "1-2 hours" was slightly wrong! Actually took me 4! The wheel arch liner bolts were so corroded, I ended up folding it out slightly to give me and arm size envelope to get my hand in. Obviously I got bruised and scratched all up my arm, but eventually got it out and then back in.
The 3 nylon gear bushes had disintegrated and looked like grated cheese, so got on and followed Tony's video greasing everything on reassembly.
Having got it all back together and reinstalling it into the car....(and 4 hours later) I tried the light switch............
They popped up in tandem, I thought excellent! Whoopee!
I then turned the lamps off but to my dismay, the left hand one stayed up! After many explitives, I found I hadn't tightened the 10mm bolt to the linkage...after tightening it, all was good.
If anyone needs help in changing these damn bushes, let me know and I can try to help!

My RH headlamp needs doing, and I've bought the kit. I'm trying to gee myself into action, knowing that if will be tricky.

Did you need to replace the gear wheel? My kit from SJ Sportscars didn't include one.

You won't need the gear wheel, just watch "the video" it will be all become clear after that. :D

Agree, the video is very clear and concise.
Personally the hardest thing is getting the wheel arch liner off (though I couldn't so took me a lot longer!)
Good luck everyone!

Thanks for your replies.

The wheel arch liner should come off easily - I replaced the fixings a couple of years' ago.

Good news...and the right one is easier than the left due to the worm gear position in the motor.
Check out you tube (https://youtu.be/OTjPoKfafSY).... good luck

You'd be better off doing both at the same time. After all, both sets of bushes will be about 25 years old and you know what happens if you only do one side !!

Yeah Sod's law, my right hand lamp was done last year by Pal Matty as part of a big list of jobs that needed doing including the head skim....shame they didn't do the left one too...
All done now though!

Haha so right. Left hand side replaced (quicker to do the repair on the motor than the liner removal - but thats done now with new fixings installed...) first test, left hand side perfect, right hand side ....whirr click, droop. *ugger. Still at least I know what I have to do now!

Thanks! All sorted now, rising & falling in perfect synchronism.

Not a great fan of those low profile bolts on the wheel arch liner (which had corroded into low profile blobs of rust) or the self-tapper at the bottom rear of the liner. Think mine had been manufactured with some spare components from the race team, a unique combination of ultra-hard and highly corrodable screwed directly into fibreglass. Two hacksaw blades later....

Motors worked fine, if they play up again any time soon, might look further into using linear actuators although the control board would need to be replaced too.

Thanks for all the tips & pointers....

Great news! As I said the hardest part are theliners, though I did find a way so as not to take them off...slightly painful in the forearm though!

As long as the screws don't mess you about it's really not that bad :)

The best area is just front of the highest point of the wheel arch, though you need a long ratchet conedction and a bendy too. It’s a bit of a bugger but easier than having to drill your wheel arch bolts off. However if they do come off easily, that’s a better way than what I had to do.
Good luck...when done it’s quite a satisfying feeling!

I did my RH headlamp motor about 2 or 3 months ago, which went very well. It did take quite a lot of hours, though. I hoped that I could get away with leaving the LH motor, but to no avail. With an MOT booked for last week, the LH headlamp stopped popping up reliably, so I decided that I had to do that one too. I finally completed the task at 1am the night before the test!

I wish that I had watched the video first because everything that I had previously read indicated that you have to withdraw the rotor from the stator in order to allow the plastic pinion gear to be removed from the worm. The instructions warned that it is tricky to get the rotor back in past the brushes. I didn't have any trouble with the paperclip method for doing that, but as the instructions say, the bolts holding the motor together always shear off, and you just have to drill them out. Well, what a nightmare it was to drill them out. If only I had known that separating the motor was unnecessary.
