Here are the two parts I need a diagram of. I mixed things up and want to make sure I put it back together correctly.

First the part that the cable runs to fron inside the cab:

 

Secoond diagram needed is this valve middle line come in from left is from manifold top lines runs to the two speed switch in previous picture bottom lines runs to the booster ? atleast this is what I believe to be correct if I am wrong let me know. Thanks Kevin

 

Kevin, yours is a little different than mine but it looks correct as is. On my truck the line from the two speed switch enters the check valve from the top instead of from the front, but it looks right. Don't forget about the vacuum line on the back of the two speed switch that runs to the speedometer. if you do not use it be sure and cap it or you will have a leak there. If you have the two speed speedometer head there is a rubber diapgrahm in it that if dryrotted will leak also.

 

I am trying to put the diaphram back toether. I have it off the truck because it was stuck so I soaked it and now need to put it back together! So I need the diagram of all parts and pcs and how to put back together. I know I am challenged

 

Good news I have an exploded veiw diagram here in my book, Bad news I have no idea how to stick it on this thread or E-mail it to you. If no one has helped you by tommorow I will get my cousin to help me he is a computer prodigy.

 

Thanks F6guy

 

Kevin, are those pictures of your COE? Here's a picture I took at a junk yard. I think it's the stock conventional cab six cyl engine arrangement.



You will find the angle bracket which supports the two speed control valve is bent at an odd angle. It doesn't need to be straightened because it screws to a curved section of the firewall. The tee/checkvalve has a big 5/8 or so stud on the back that extends through the firewall and secures with a big thin nut. There's an 1/8 in. pipe connection in the middle of the big stud. I think that's where the vacuum wiper line connects.

Here's a cutaway picture of the two speed control valve.

Thanks that is what I needed. I will put it back together tomorrow.
