What do the numbers on the ring gear mean?

What do the numbers on the ring gear mean?

The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.

How do I know what size ring gear my Ford has?

The ring gear diameter is measured across the face of the gear. To obtain the ring gear diameter, simply place a tape measurer across the gear. This can be tricky if the ring gear & carrier are still in the housing. In some cases, a differential can be identified by the number of cover bolts is has.

How do I tell what gear ratio my ring gear is?

Count the number of teeth on the pinion gear and count the number of teeth on the ring gear. Divide the ring gear teeth number by the number of teeth on the pinion. The result is your gear ratio.

Is the gear ratio stamped on ring?

If you are not sure about your results when using the wheel rotation method, the number of teeth is stamped on the ring gear. The large number is the ring-gear tooth count. To find the gear ratio, divide the big number by the little number.

How can I tell if my Ford is 8-inch or 9-inch?

There’s an easy way to tell an 8-inch apart from a 9-inch. All of the 8-inch case nuts can be accessed with a socket. In contrast, on the 9-inch, two nuts on the bottom at about the 6 and 7 o’clock positions cannot be accessed with a socket and require a wrench.

When did Ford add axle ratio to the rear axle tag?

These tags were not that informativeon the early units, so from 1957 to 1962 the tag just referenced axle ratio. In 1963, Ford included more information. This is a typical axle tag that has been removed from the third member. The code, 4L11, tells us that it is a 4.11:1 ratio with a limited-slip or Traction-Lok differential.
