Postby brianJ » Sun Apr 27, 2008 12:07 am

Hi All
Would anyone have torque specs for a Super A? The neighbor was asking today and I told him I would post the question here.

Brian:

You might want to have a look on the server.. not a lot, but some stuff for the Super A, AV, but might be enough.

I found this on farmallcub.info from the Blue Ribbon specs manual

Image

It states 80 ft/lb for head torque. Why would the I & T spec 65 ft/lb and the blue ribbon says 80 ft/ lbs. Which is correct? What would you fellas suggest?

I may depend on the material of the head gasket. The old ones were asbestos and you had to crush them to seal it. The newer ones are coated steel. May not take as much torque. Check what the head gasket says.
