Where do I find my rear end gear ratio?
You can typically find your RPO code on driver side door panel or glove box. General Motors rear end differentials are referred to by the diameter of the ring gear, i.e. 7.5 inch, 8.5 inch, 10.5 inch. Our experts will help you find the correct ring and pinion set for your particular application. Give us a call at 800-216-1632 to get started.
What do you need to know about axle gear ratio?
People who are buying a used vehicle, or shopping for an axle from a junk yard, frequently need to know what the ring and pinion gear ratio is in the axle’s differential, as well as whether or not the axle has some sort of traction control device like a limited slip, locker, or spool.
How to calculate the ratio of drive and drive gears?
Divide the number of teeth on each “driven” gear by the number of teeth on the “drive” gear for each interlocking set of gears to calculate the intermediate gear ratios. In our example, the intermediate gear ratios are 20/7 = 2.9 and 30/20 = 1.5.
How to find your differential gear ratio without stamps?
Often times diff tags are lost or missing. Many times you can call the dealership with a VIN number and still not be able to find out decisively what your ratio is. Well you’re in luck! A gear ratio is a description of how many times your driveshaft rotates to make your wheel/axle/hub rotate ONCE. You can physically count it.
How can I tell what gear ratio I have?
Count the number of teeth on the drive gear. One simple way to find the gear ratio between two interlocking gears is to compare the number of teeth (the little peg-like protrusions at the edge of the wheel) that they both have. Start by determining how many teeth are on the drive gear.
How to tell which gear ratio I have?
Part 3 of 5: Determining an approximation of your car’s gear ratio Place a visible mark on the driveshaft near the differential housing. Use the chalk or paint pen. Spin the driveshaft by hand. While spinning the driveshaft, count the revolutions by watching the markings, as well as counting the revolutions of the tire at the same Continue spinning the driveshaft.
How do you calculate gearing ratio?
A general way to calculate the gearing ratio is to add up all of the company’s debts and divide them by shareholder’s equity. If you do not have any shareholders, then you (the owner) are the only shareholder, and the equity in this equation is yours.
What do gear ratios tell me?
In mechanical engineering, a gear ratio is a direct measure of the ratio of the rotational speeds of two or more interlocking gears .
