When do you have to replace the gears in a differential?
When do you have to replace the gears in a differential?
If a differential runs low on gear oil for even a short time it results in serious damage so that it is unrepairable; you have to replace the gears. Ring gears convert the engine’s rotation into forward motion, but there is more to selecting a gear set than just what size you think you need.
How are hypoid gears shaped in a differential?
The gears are shaped as a revolved hyperboloid, which means that the pitch surface of the gear itself is a hyperbolic surface. Hypoid gears are centered off-axis, where the pinion gear sits lower than the centerline of the ring gear, allowing the pinion gear to be larger than it would be if it were on-center.
How big is the pinion gear in a Chevy?
The gear measures 8.8 inches, which is noted in the part code: GM8.8-373. To change gear ratios, you need different pinion gear sizes. This pinion gear (left) is a 4.11, and the gear (right) is a 3.08.
Is the gearing of a car the same as the engine?
Shift the transmission into fourth, and the gearing of the transmission is 1:1, so the torque and RPM of the transmission is exactly the same as the engine (minus a little bit for parasitic loss). The first calculation determines the torque needed from the gears, just 1,287 ft-lbs, to move the car.
How do you change gears on a rearend?
The actual amount of change obtained will vary depending upon the gear ratio and gear size. A loose or high backlash (too much), is corrected by shimming the differential and moving it closer to the pinion gear. A low or tight backlash (not enough), is corrected by moving the differential away from the pinion.
What are the advantages of rear end gearing?
The fuel savings or increased acceleration advantages can be quite dramatic with a change in differential gearing. And you can select how much of a change you want with the large variety of sizes available on the market today from such rear end gear manufacturers as Richmond, Motive, and Strange Engineering to name a few.
What is the ratio of gears in the rear end differential?
This is the ratio of gears in the rearend (differential) that you may have heard of in the numerical terms 2.73 to one, 3.23 to one, 3.55 to one, 3.73 to one, and 4.10 to one (commonly written in the following manner 3.23:1 with a colon).
How do you get the gears out of a Mustang?
4. Remove the five lower differential cover bolts and loosen the five upper bolts, allowing you to softly tap the bottom edge of the cover, opening it up “clam shell style”. Empty the lube into a container below. The sway bar must also be removed or lowered, to gain complete access to the gears, as shown in Fig. 1
