wiper motor dead

[V8Bart]

Wipers decided to pack in last week, so I spent 3 days stripping and rebuilding the motor and gears.
Just fitted back in and with the wipers lifted off the screen they work, but just die when on the glass.

Presumably it's a new mechanism needed? Any tips for cheap fix? Seems like the motor is the issue. Lol

Thanks for any advice.

I fitted a 14W unit from these people. http://www.s-v-c.co.uk/category/wiper-systems-and-... Straight swap bar a very slight bend needed in the strap as the body of the motor is slightly smaller.

Doesnt sweep quite as far but not really an issue. The wipers fly across even a dry screen now no problem.

Only other alternative is Adrian@ on here who can rebuild yours with all new parts, not cheap tho.

Have a look at a thread I started 8 March 2014. I've knackered my spindles which are a real pain to replace. I got advice about only trying the wiper on a wet screen with the engine running. You don't want to burn out the electrics or bend anything !

Adrian will be at the Growl. He rebuilt mine and is the only person who can get parts of the original manufacturer.
If you want me to drop you his contact details let me know.

Cheers guys, you have pm Paul. seems 50 quid alternative is also a good option.

I think you will find that your insurance company will pull you on on this. I had a call from a well known broker, when a person recently tried to 'cover' the 'modification' on his policy, as they were 'no longer available'...just saying.
Adrian@

That sounds very far fetched, as the 'modification' affects neither the performance nor the value I wouldn't even declare it (and I've an insurance background).

Is there any obvious test to see if struggling wipers are down to the motor or something else? Mine have barely worked on a dry screen since I bought the car but work OK when the screen is wet, something that has always troubled me but only really at MOT time as I so rarely drive it in the rain. Hence not looking at it too hard to date, this thread has just reminded me that I really ought to do something about it!

The difference in the 14w sweep is less but only fractionally. It sweeps perfectly adequately to clear the screen.

If your that bothered position the wiper arm slightly further over on the spindle when its at rest then there is no difference.

Have you tried replacing the brush set? IIRC it's a Lucas part, originally from an XJ-S. If you can't find an XJ-S one, the brush sets from other Lucas motors are quite often the same. I used one from a Mini wiper motor, which I found through a salvage yard. Cost me five quid! If you've dismantled your own wiper motor already, you can see that the brush set is very easy to swap over.

Cheers for that,
The brushes are in good Nick, I cleaned them and the armature so have come to the conclusion that the motor needs 're winding.

HELP!
Lol, only gets worse because the brass sheath collar has sheared off so it causes the motor to move under load.
Spent hours trying to solve but only made it worse.

Correct me if I'm wrong here....but that does look as if you tried to fit a 14W motor and it does not fit! and forcing the motor into position the outer rack tube has sheared the flaring off the end of the rack tube. (you have said thanks to the person who gave you the good advice)

Hi Adrian,
It is the 14w motor as it made more sense for me to have a new replacement. It fits perfectly as the old one did (just shorter on the end towards the outside so no change to operation), and will be perfect for my needs, but the new loop bracket I got is not as solid as the old one and when I tried on a dry screen the bracket (though tight) twisted and allowed the motor to move hence the break.
It's fine with the old one back on. So the advice was very good. ;-)

So any advice about the rack tube?

Cheers. Ian.

[carsy]

No problem, glad i helped. As i say mine fits and works perfect and with plenty of wumph.

[Adrian@]

Yeah, the advice was VERY good AND for the point of fact, and this thread, it IS why you are where you are now (shouting HELP!!)...and you still have not got, will not have, wipers that wipe the screen properly on your 140 MPH sports car. The reason the flare on outer tube snapped, was because the mounting position of the 14W is an inch or so away from the end of the tube (for the wipers to work the 3 outer tubes are mounted to both the wheel boxes and wiper motor by flared joints... you need make a hole in the heater distribution box to get access to the wheel box to replace the outer tube, (to do the job properly, by removing the the distribution box to get at the assembly BUT THEN you might be lucky and have the TVR shell with access ports behind the dash).
I make the OE tube (as I know the length and supply on the VERY odd occasion) BUT I will not be party to creating an un-safe car (my liability insurance would not allow that) I will, as I did to Carsy offer to help put the OE system back on the car at cost.
Adrian@

And as you might of noticed ..I rarely leave my posts on PH ..but for this special occasion I think I just might.

Cheers for that Adrian, will bare you in mind if can get a mechanic to fit it, it will have to wait for now.

It's all irrelevant as I physically can't manage to access the heater distribution box anyway.
