MG MGA - Wiper motor mounting position

The wiper motor on my A is bolted to a mounting bracket but is just laying on the bulkhead . None of the mounting holes line up with holes on the bulkhead although the car was LHD, is this the reason why nothing is lined up . Looking at the manual and parts list does not help as it not shown in the manual and its mounting position not shown in the parts list.
Has anybody got a photo that might help? or a drawing.

Thanks Roy

My car was left hand drive. I converted to RHD but the motor stays in the same position.

From the attached photo you will see one forward hole about 3" outboard of the LHD MC/pedal assembly forward mounting bolt. There should be a rivetted angled plate at the back to attach the rear part of the wiper mounting bracket.

And a drawing of the support bracket here: http://mgaguru.com/mgtech/electric/et113d.htm

If anyone has the dimensions for the mounting plate, I would be happy to make a drawing and post that one too.

Steve , thanks for the photos. A few things come to light, it looks like i am missing the bracket that tilts the wiper motor at an angle . Steve your bracket has one bolt to mount to the bulkhead is that correct? and Barneys drawing shows 2 bolts onto the bulkhead. And also i wonder if the steel tube that has been replaced from the wheel box to the motor on my car could be too long and its pushed the motor forwards away from the mounting holes?.

Thanks Roy

Roy (sorry got your name wrong in first post)

The bracket is as shown in Barney's diagrams. The second rear rivetted attachment is just out of view in my photo. The bracket is designed to straddle the bonnet operating rod (photo).

Looks like a winter clean up and paint job for me round there!

Hi Roy here are 2 photos of the wiper mounting on my coupe (after restoration) which should make it fairly clear to you.

Mine looked like that once! Now one for the purists, should the rivetted bracket be body colour?

Steve
Steve Gyles

Steve, it's not riveted, they are the ends of the threaded studs (see Barney's drawing). It's not part of the body and would originally have been black.

I hope you are right Neil. That will make it easier for me to clean up and paint that area. They look like rivets from the engine compartment. Just went and had a look and I have a speaker covering the underside of the bolts/rivets area.

Steve
Steve Gyles

Yes, you were correct Neil. I was using those 2 bolts through the bulkhead to secure my left hand speaker box!

Trouble with these threads is that you try to help someone out with a photograph and then see that during the process you also need to do some renovation work in that area! Currently dismantling the bracket for painting. Anyone want a picture of it whilst it's on the bench?

Hi Steve , yes please if you could post a photo. Roy

Photo attached. Great fun getting it and the wiper motor out. The manual says to remove the wiper top cover, remove a circlip and lift the operating rod out to release the winder inner cable. Barney's site says this is very difficult. Instead, remove wiper arms and pull the entire unit complete with inner cable. The theory is good. However, there appeared to be an end stop on my inner cable and I could only pull it about 2 inches. I resorted to the manual's instructions. Fiddly doing it with head upside down but managed it by the book. It will be interesting getting it all back in!

Incidentally, the slope on the bracket is 12 degrees.

Thanks Steve, Before i make one up dont suppose anybody has a spare bracket from a parts car knocking about.

Steve,

Interesting. Is the top bolt screwed into a tapped hole in the bracket? This was originally a pressed in threaded stud similar to the bottom studs, but larger. Your picture looks like the top stus was broken or cut, then drilled and tapped through the original stud head.

Since you have this disassembled, can you get dimensions for the mounting plate so I can make a drawing?
Barney Gaylord

Barney

Yes, the top hole is tapped. Looking at it closely I would say it is totally original in that it has been tapped crooked! This would tie in perfectly with 1950s British cars that were assembled on Friday afternoons after the workers had spent their wages for the week (normally paid Friday morning) down the pub!

Seriously though,It does kind of look quite neat and original except for the crooked tapping. No distortion from welding; no welding marks etc. Looks like it has been pressed in. A bit of untidy burr from the tapping.

Steve

PS. If it is not original, then the modification was done in California!!!!!




Steve Gyles

Barney

I have had a closer look through a magnifying glass. I would say drilled and tapped through the original stud head. Poorly executed bit of work. Off centre and crooked.

Working on the measurements for the other bracket. Will PDF the drawing to you within the next day.

I can just see you with your magnifying glass Steve - only need a deer-stalker and you will be another Sherlock Holmes!
Cam Cunningham

Very good Cam. However my magnifying glass comes with 240 volts mains supply! I don't wear hats indoors.

Just been bollocked by 'her indoors'. Put my painted brackets in the airing cupboard to dry off more quickly in this damp, misty weather system!
