What Is The Coast Side Of A Ring Gear?

What Is The Coast Side Of A Ring Gear? Coast pattern (concave side of gear) moves lower and toward the toe. (2) Increasing backlash moves the ring gear away from the pinion. Drive pattern moves slightly higher and toward the heel. Coast pattern moves higher and towards the heel.

What is the drive side of a ring gear? The contact pattern on the drive side (convex) of the tooth is mostly towards the toe. The contact pattern on the drive side (convex) of the tooth is mostly towards the heel. The contact pattern on the coast side (concave) of the tooth is mostly towards the heel.

What is the convex side of a ring gear? Technician A says that the convex side of the ring gear is the drive side on most rear axle assemblies.

How are ring gears measured? 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.

What Is The Coast Side Of A Ring Gear? – Related Questions

Can you reuse a pinion crush sleeve?

You can reuse a crush sleeve if you can obtain the desired bearing preload ( inch pounds of drag ) and still maintain a decent torque on the pinion nut.

Why are ring and drive pinion gears lapped?

Lapping typically improves the wear properties of gear teeth, and corrects the minute errors in involute profile, helix angle, tooth spacing and concentricity created in the forming, cutting or in the heat treatment of the gears.

How do I lower my ring gear backlash?

If using shims: Adding shims on the ring-gear’s smooth side of the carrier moves the ring-gear closer to the pinion, causing the teeth to mesh tighter, decreasing the amount the backlash.
Adding shims on the other side moves the ring-gear teeth away from the pinion, increasing backlash.

How do I know my diff size?

Measure the ring gear diameter.
The ring gear is the largest gear inside the differential housing and normally faces the driver’s-side rear wheel.
Using a tape measure or machinist’s ruler, measure the ring gear diameter.
This identifies the differential — a Ford 9-inch or GM 7.
5-inch — for example.

How do I know what Differential I have?

Without an ID tag, differentials are identified by the number of cover bolts, the distinctive shape of the cover, the number of ring gear bolts, and ring gear diameter. They can also be identified by whether the center section is an integral or dropout design.

What’s the difference between 4.10 and 3.73 gears?

4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster.

How do I know what gear ratio I need?

Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio.

How many teeth does a 4.10 ring gear have?

The 4.10 has 41 ring and 10 pinion. Also there are 3.08 and 3.07 ratios for different rearends.

Do I need a new pinion nut?

Do not replace the pinion nut. You need to count the number of turns on the nut when replacing the pinion seal to get your bearing preload back.

How much torque does it take to crush a crush sleeve?

On a crush sleeve design differential it usually takes between 300 and 400 ft-lbs of torque to crush the crush sleeve.
Over the years we have used huge breaker bars and/or very strong air operated impact wrenches to crush the crush sleeve.

What does a pinion crush sleeve do?

The crush sleeve is between the inner and outer pinion bearings. The sleeves job is to keep the pressure outward against the two bearings. The crush sleeve as in its name is to be crushed upon final differential assembly and keeps the bearings pressure consistent in the bearing cups.

How much does it cost to have a ring and pinion install?

$400 for ring and pinion front and rear, another $300 to $400 for master install kits, $400 to $600 for labor.

What do the numbers on the end of a pinion gear mean?

Note the etched number on the face of the pinion gear head (–1, –2, 0, +1, +2, etc.). The numbers represent thousands of an inch deviation from the standard. If the number is negative, add that value to the required thickness of the depth shims.

What happens if pinion depth is wrong?

Again, you’ll need to determine the proper spacing by using a pinion depth setting tool to ensure proper installation. Improper gear spacing will lead to wear and damage to your gear set. If this setting is not correct, it may cause overheating or damage to the gears.

How do you choose a gear?

A pair of gears can mesh correctly only if Module of both gears are same. So select the gear with the same Module (M) to be mesh together with the Different number of teeth according to your Gear ratio requirement.

What is gear tooth contact?

The contact between the gear teeth surfaces is “non-conformal”, i.
e.
, it nominally (under zero load) involves a line or point of contact, generating small-area concentrated contacts.
Under these conditions, elasto-hydrodynamic (EHD) is the predominant lubrication regime.

How can I improve my backlash?

Backlash is most commonly created by cutting the teeth deeper into the gears than the ideal depth. Another way of introducing backlash is by increasing the center distances between the gears. Standard practice is to make allowance for half the backlash in the tooth thickness of each gear.
