Am Multigraphics plate cylinder clamp

Dear Fellow Printers
I've installed an old Am Multigraphics. Can't get the spring loaded plate cylinder clamp to work, after replacing some parts inside the cylinder.
It's the kind that has teeth that attaches to the plate
Is there a manual showing these parts

 

Is it a pinbar clamp on lead and tail end? Or the old style that uses the teeth to hold tail of the plate in? If old style there's just 2 springs that tension it. Lift the tail of the clamp and put it in the holes in tail of plate. The lead edge can either sit on the pins or clamp mouth opens to put the plate inside. Printers Parts in Florida USA does sell a copy of the old manuals. Paper or PDF. Think they have the parts too. I have a 1650 manual and will look to see if that style clamp is in there.

 

What is the model Sir?

 

It's Am 2675S model. I've a problem with the spring that is installed on the cam at the side of the cylinder. Can't manage to find one that works

 

Sir:
See if this attachements, can help you.

 

Yes Mr. CHOCK thats the one.

 

Thank you.
