Beta wiper motor

[pimms]

I am using a Beta wiper motor, an have constructed a mounting plate. I have to make the rod between the wiper motor arm and the wiper arm at the right length to get the right angle for the wiper blade. Picture attached!
What is the angle that the wiper blade makes on the original Strato's?
What is the length of the wiper arm and the length of the wiper blade?

Regards, Pim

I think it's a 90 degree sweep that you need Pim but I stand to be corrected. The arm is 18 inches and the blade 22 inches.

The length of the arm on the wiper motor itself is critical to get the correct sweep on the wiper blade. The formula for determining the length was shown in one of the early newsletters but i can't recall which.

It was newsletter nr 5, a fact sheet by S. Richards.
He mentioned 95 degrees aybe thats the original. I use the Beta motor arm of 43mm. and a 59,8mm arm on the wiper axle. Changing the lenght between those two also changes the sweep angle of the wiper blade. I tried it out with a cardboard template.

Thanks!

My wiper motor works, but no self park yet. I read John Rutters explanation in one of the earlier newsletters. He had also used a Beta wiper motor and figured out the self park system.
Except his Beta motor seems to have 6 wires as mine has only 5?
Any one else have experience?

Pimm,

Bit late now maybe, but I found the Alfa 164 wiper motor to be a far nicer bit of kit. It's pretty much self contained, including a delay wipe function and it's physically smaller and more powerful than the old Beta item.

I'm using a Beta wiper switch with it and the hook up was straightforward.

Only fiddle is having to lock the wiper retract mechanism. When the motor parks, it rotates backwards, which lengthens the operating arm slightly, meaning the blades travel below the line of the bonnet on the 164

I have Mr Richards original drawings and calculations, all included when I bought his kit. All that work and I used a Rover motor that doesn't really work that well, bit too much sweep.

Interesting note on the 164 motor, must be fitted to many other types of cars. I wonder which?
