The GMC CCKW

hello can anyone provide me with a picture of a type 3 hydrovac because I would like to know which one is fitted on my cckw.

thanks
tom

No Pic but...
I can give you a brief description of the spotting features.
Type 1 Dual diaphram with triangular plates on each end w/rods ( to hold assembly together)
Type 2 Dual diaphram with cast type " J " hooks instead of triangular plates ( same purpose as above )
Type 3 Single diaphram with J hooks/rods
The type 3 are avail new thru many parts outlets ( at least stateside )

Hope this helps
John

Not sure if it is this will help, but here are pictures of 2 hydrovacs I rebuilt :

typeI:


typeIII:


Thierry.

thanks for the responses I think it is the type III thats fitted on my truck . Does a "french" hydrovac looks like a typeIII or is it completely different? My truck is ex french army that why I would like to know it .
does anyone know the partnumber(bendix-gm?) of a revision set for a type III hydrovac?
thanks
greetings

The "typeIII" on my second picture is made in France and is typical on many trucks that have been rebuild here in France. Mine is marked EB6 BENDIX E2 9/16 one one side and BENDIX MADE IN FRANCE on the other side, but I found no part or serial number


Thierry.

but are there differences between an original american typeIII hydrovac and the french type III hydrovac. because I've been told that you can't find parts anymore for the "french"hydrovac.

greetings
tom

I believe the parts should be the same but I'm not sure...Parts are hard to find for all type of hydrovac...

I'm missing cups for all types of hydrovacs so if anybody know of a source I would appreciate...


Thierry.

If by "cups" you mean the rubber piston seals, thay are I believe 3/4" and available. I bought mine from Rex Ward:

but they were French origin.

Many thanks Karoshi,

Yes, I need the rubber piston seals. I just E-mailed Rex...
