Can any of you kind people help with the following, (for a 1963 Comet S22); I need - * A blow up view of the rear 1/2 axle * Type of gasket used to mount axle hub to drum - rubber or cork type * Spark plug gap * Torque for head * Correct compression And any link for other such specifications for this car. Restoration is under way! :bananaman Thank you so very much in advance.
You have a 7.5" rear axle - you can get a picture of the assembly from a six cylinder 65-66 Mustang. Plug gap os factory - .034" I had better performance and longer life using .028" - .030". Head bolt torque is 70 - 75 foot lbs. If you use clean threads and antiseize on the threads and under the head of the bolts use the 70 foot lbs as maximum. Ford doesn't publish compression pressures but I would expect to see 150 psi when cranked six times on each plug, carb held wide open while cranking with a fully charged battery, engine at operating temperature,all plugs removed before beginning. The most important aspect of a compression test is that no cylinder should be less than 90% of the highest. (10% variation max). 150 - 135 would be considered OK by Ford.
What size engine? Ford used 3 different 6 cylinder rear ends in '63. 144 used either a 6.75" one window case or the two window case, 170 used the 7.25" two window case. http://1bad6t.com/images/diffcase.jpg Use the paper type gasket on the axle tube/bearing retainer. Ford says +/- 20 pounds variation between cylinders is satisfactory but recommends all cylinders should be uniform within 10 pounds Here is the shop manual...use the 60-62 if you have a 6 cyl or the '63 supplement if a V8 http://falconfaq.dyndns.org/
