2.4 / 2.7 Crankshaft specs
 
Can someone provide the main and rod journal measurements and tolerances for a 2.4 / 2.7 crankshaft, or let me know where I can find them?

Thanks

Kevin,

From the factory manual:

Connecting Rod, 51.971 to 51.990mm, 2.0461" to 2.0468"

#8 Main, 30.980 to 30.993mm, 1.2197" to 1.2202"

For undersize,
Subtract .25mm or .0098", .50mm or .0197", .75mm or .0295"

Check out the January 1972 Panorama article in UpFixen- John Lutejen posted a scan of the original pages but I can't seem to locate it in the archives.
