CMP windshield throwout arm assemblies

[Tony Smith]

Note that many US WW2 and post-war vehicles also used the Trico S Series, but there are detail differences with the models used on Canadian vehicles, particularly the mounting dimensions. Jeeps and Dodges used the S 583. The Canadian applications seem to have a simpler design assist lever than the US versions.

While it relates to the physical dimensions of a post-war S Series unit fitted to a CJ2A Jeep, there is a good re-build write up of these units here: https://www.thecj2apage.com/forums/u...uide_rev_1.pdf

Hi Tony,

Here is the bracket attached to the wiper motor on a Cab 13 Ford. This bracket is then attached to the bracket on the window frame.

Note the arm on the shaft to enable "manual override" when accelerating or under load when the vacuum drops off. (Or any other time when needed)

I have two different length shafts of the same type bracket. This is the shorter one and I am using the longer version on my cab 13.

Thought this might be of some interest.

Cheers,

Lynn, Tony and Jacques,
Thank you for all your information.
I have a clearer understanding now of the motor and various model setups.
All I need now are some dimensions to finish the drawing.
I've attached a rough sketch to show the dimensions in question, from which I should be able to scale the rest.
Any help would be greatly appreciated and drawing posted when complete.
I presume (which is always dangerous!) that the main dimensions will be similar throughout the different models, with only details like mountings and spindles varying depending on model.
