Hi all.
The passenger side window motor has decided to play up. The plastic gear wheel in the motor gear box is slipping so I assume I need a new motor. I did pull it apart a few weeks ago and cleaned it out and re greased the gears. I put it all black together and adjusted the window stops and it was working fine. Tried it yesterday and the gear is slipping. Can anybody point me in the right direction either new or SH. 1991 pre facelift convertible.
cheers Rob.

 

I believe all right side XJS window regulators 1985-1996 will interchange, with only slight modification.
The motor cases on pre-facelift are round where the later are somewhat 'flattened'.
All the geometry and fastenings are identical, to the best of my feeble memory.
The only modification needed is the different power plug.

 

JLM11003 is the part number I need looks like it’s not available. Anyone know of an alternative which will fit.
Rob.

 

You should be able to use any right side XJS regulator.
Only functional difference is power connector.

 

Both left and right motors seem to be unavailable.

The motor is fine it seems to be the plastic gear which is driven by the worm that’s failed. Don’t suppose anyone has an old unit they would like to sell. I’m sure I could rebuild with a decent plastic gear.
Rob.

 

Can you post a photo of it? The earlier ones were standard GM motors I believe, so are common in North America.

 

I have one from an '88 convertible that I recently parted.

I have shipped to europe but it's not cheap. I'll sell the motor for $35 USD plus shipping via US Postal Service (cheapest).
Paypal payment. Happy to help if i can.

 

This is the passenger door motor.

 

I have striped the motor gear box.



this is the gear as you can see the teeth have striped.



don’t suppose anybody has a scrap motor. I only need the plastic gear as everything else is fine.
cheers Rob.

 

That's different from the GM motor I have, otherwise I could send you a gear. Have you tried Eurojag in Darlington?

 

No I haven’t tried them will give them a call in the morning. As I have nothing to lose I thought I would try turning the gear over and fettle it so it fits and see if that will work as the worn teeth are on one side of the gear. I will post some pictures if this works out ok.
Rob.

 

Hi Brad.
Is the motor you have the same as I have pictured. This is a Delco part.
Cheers Rob.

 

Hello,
Sorry for the delayed reply.
Yes, it is identical. It has the flat side the same as your picture.
I have removed it from the door now. I did not open up the motor but it is separated from the actuator arm (3 screws). All I would have to do is wipe it off and box it up.

 

Cheers Brad.
can you let me know the total cost including post to the UK.
Rob.

 

Hi Rob,

I'll need an address. Once I get that I can get a shipping quote.
I have found the cheapest way is by the U.S. Postal Service. (FedEx and UPS are much more expensive).
The motor fits into a a USPS 'If it fits it ships' box for $5.60. Not sure if that applies to overseas but we'll see.

I take payment by PayPal sent to my e-mail address.

 

Hi Brad .
I have sent a PM with my address.
Rob.

 

Just a quick update. Turning the gear didn’t work so in the end I got a reconditioned motor from Simply Performance.

 

Going through the same pain. Unable to obtain a replacement nylon gear or a replacement motor at a reasonable price.
My '89 Coupe LH passenger side motor is identical to the one in the previous post.

This is what I believe caused the stripped Nylon gear teeth.


Firstly I checked against a round case motor but it had more teeth of a different pitch although it will bolt to the alternative holes in the plate.


I dismantled the gear box by grinding off the end of the peened over shaft to remove the drive gear and found this off set wear pattern on the stripped teeth.


So I removed this protrusion to shift the gear across.


This gave me a 1mm shoulder for a spacer washer.


I fitted a 1mm copper washer and reassembled using locktite on the splined shaft.


Here is the new engagement.


This will hopefully give the window a new lease on life.
