Wiper assembly

[Vinman1]

In need of a complete wiper assembly for my 1979 RHD Seven. I believe they came from the Mini, just not sure of cutoff years. Moss has parts from 1969 on. Would be happy with a decent used on that came off a Seven.

Looks like it would be an on/off toggle, no self-park, not intermittent, and one speed. The gear stroke is probably less than a 115deg sweep.

I'd work backwards from the appropriate wiper arm to determine the wheel boxes with the right pin type. Newer, more common motors with more functions could be used with just a toggle but the stroke could be critical with a fixed windscreen frame to wiper box distance.

A three position toggle could provide two speeds. Self park just means operating it to allow it to park before installing the arms. Intermittent is a bit more complicated.

I found in an early owners manual the motor described as "DR2" and having a self parking feature. This would be the single speed motor sourced from the pre-69 mini among other applications:

I think all the cats with a washer switch have an intermittent wipe relay box and two speeds.

I believe you will find the wiper motor is the same one used in all the British sports cars. Moss has them. The wipers are moved through a cable inside a tube and that is different for different cars. In the late 60s the motor changed to two speeds and the earlier one I believe has been discontinued. Here is some information that might help. I downloaded this off the web and there are some duplicates. I did not want to use the Lucus switch that is made to work with the wiper motor. I used the wiring diagram marked Factory Five. That worked for me. Lucas windscreen wiper motor 75704.docx

I am constantly amazed by the depth of knowledge and the willingness to share it on this forum.

Thanks guys for the reply and great info. Since I do not have a core, I am leaning towards getting part # 60027020A from Caterham. They have informed me that the wheel box spacing will not be correct, but I believe the spacing can be modified by trimming the tubes.

If the wheel box location on your car is not closer to the windscreen vertical frame, the arms and blades are not longer, and the blades do not mount at a different angle on the arm, then the s3 gear should work. The gear determines the stroke from how far the link pin is off center, how far the spring moves back and forth in the tube, and ultimately how far the arm will swing back and forth.

Hopefully the difference in spacing they were referring to is between the wheel boxes. It would help to know how many degrees the system is so you could make a template for minimum wheel box distance to the vertical frame.

From what they said, I believe it is. I ordered it, and will post how it worked out. The car so far...

To follow up. Part # 60027020A from Caterham was made to work with relative ease. Had to shorten and re-flare the tubes between the motor and left wheelbox and the tube between the wheelboxes, and make / flare a longer tube after the right wheelbox. No big deal at all. With shipping, still worked out better than getting just the motor (with no core return)  this side of the pond

FYI on the pic of the wiper motor set up. I slid tygon tubing over the wiper metal tubes and zip tied them, just for added protection between them and wiring
