Title: 160 tooth flywheel?
Post by: priceless on December 31, 2015, 12:48:26 PM

What flywheel came with 160 teeth? I have done a search and only see flywheels with 157 teeth or 164 teeth.
Any help appreciated,
Rich

A google search reveals; early K codes and Fairlanes came with 160 teeth ring gears.  Further early V8'S used that gear and some automatic's used a 160 ring gear.  Interestingly it seems the same starter motor would inter change with the manual 160 or 157 tooth gear.  Brian

This one is also a C3OE-6380-B. The date on this one is 3k13(Oct 13,'63). Must be for an early K code is what I'm figuring. Do these flywheels bring much? I have one in my possession that I'm wanting to sale. Just need to know value so I can price it accordingly.
Any help appreciated,
Rich

Older flywheels tend to have micro fractures, they are old. They need to be inspected. The problem is the  fractures show up after a resurfacing. Just a heads up.

I have seen C3OE-6380-B flywheels with the original 160 tooth ring gear dated as late as mid-66.

Standard flywheels also have a C3OE-6380-B casting number. HiPo flywheels have a different imbalance, 30.4 oz HiPo / 28.2 oz standard, plus also have a Brinnel hardness test mark (image arrow) and an orange paint daub.

So that everyone will understand the 157 to 160 tooth controversy better I will try to explain it here. First of all the 164 tooth flywheel is not involved here as it is a larger diameter flywheel although it began life as a 168 tooth flywheel. The early smaller flywheels up until around 1968 had 160 teeth. Then Ford decided that a 157 tooth ring gear would be less damaged by the starter drive gear. After that the 160 tooth ring gear was replaced by Ford with the 157 tooth ring gear in flywheel, flex plate and replacement ring gears. I had to explain this to a lot of my customers back in the day when I was still a Ford parts manager.
