What does the weight of gear oil mean?
What does the weight of gear oil mean?
The SAE grading system indicates oil viscosity in simple numbers ranging from the thin oil (10) to the very thick oil (140 or above). Heavier weight, or higher grade oil is more viscous and therefore thicker as it flows between the gears.
Why do I need to change the oil in my gearbox?
Changing the oil often is a proven method of avoiding corrosion. Wear of the gear teeth is something that is both inevitable and unavoidable. However, ensuring the gears have lots of clean and suitable lubricating oil can greatly decrease the rate of surface wear.
Why are the bearings in a gearbox so important?
One of the fundamental functions of the bearings in a transmission is to maintain the correct clearance between pairs of gears. If the bearings begin to wear and loosen, the gears can start to mesh improperly and become damaged from the crooked tooth contact.
How is the viscosity of gear oil determined?
Though there are several different measurements for viscosity, the one standard with gear and other automotive oil is the Society of Automotive Engineers (SAE) weight classification. The larger the SAE grade number the more viscous the oil. Viscosity is affected by temperature.

What kind of oil does a manual gearbox use?
The new oil I use is EP 80W-90 Hypoid Light Gear Oil, the label on the back says it’s suitable for manual gearboxes. The new gearbox oil now needs to go in to the filling awkward hole. Fortunately, the bottles the oil comes in have a pull-out spout.
Why does the oil leak out of the gearbox?
The gearbox oil also lubricates the rear axle, so when you have the brakes completely apart, e.g. when replacing a rear backplate, the oil will leak out and need replacing. The gearbox is just in front of the engine.

Which is thicker gear oil or engine oil?
For starters, gear oil can come in much higher viscosity ratings. In other words, a 80w-90 gear oil is much “thicker” than a 5w-30 engine oil. But viscosity is only part of the equation. Here’s why: Manual transmissions are often made up of different metals.
What kind of oil do you put in gear oil?
So you may see gear oil listed as “75W-90” which gives you both the winter and hot weights of the oil. Instead of switching out the oil during the year to compensate for the changing temperatures, most equipment will allow a multi-grade oil to be used year-round (check your manufacturer’s specifications to be sure).
Which is best American lubrication or tank package?
For 100 years, American Lubrication Equipment Corporation has provided the best solutions for dispensing lubricants. Our pre-assembled tank packages are the most cost-effective way to dispense bulk lubricant in today’s marketplace. Tank packages eliminate the expense associated with lubrication equipment installations.
How to measure the amount of oil in a tank?
1 Remove your oil fill cap and insert the stick into the tank until it reaches the bottom. 2 Remove the stick and take note of the amount of oil in inches that is showing on the stick. 3 Compare the number of inches on your stick with your fuel oil tank size on the chart to determine an estimated amount of gallons.

When to change gear oil in a car?
Keep in mind that most modern manual transmissions have gear oil service intervals well north of 50,000 miles, with many being “lifetime” oils. Driving enthusiasts, however, change gear oil to deliver improved transmission performance—like smoother shifting or added durability in extreme conditions.
