What is SAE 90 hypoid gear oil?
What is SAE 90 hypoid gear oil?
GEAR OIL HYPOID SAE 80W/90 is a high-pressure gear oil that can be used wherever very high levels of stress occur, such as in cardan joints, hypoid gears etc. GEAR OIL HYPOID SAE 80W/90 is used in motorbikes for which GL-5 gear oil is specified by the manufacturer.
Is hypoid gear oil the same as GL-5?
The main difference between GL-4 and GL-5 gear oils is the amount of EP additives. GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
What does GL-5 mean in gear oil?
A GL-5 grade oil has a very high rating for EP (Extreme Pressure) protection. EP gear oils contain additives that prevent metal surfaces from cold welding under the extreme pressure conditions found in situations where boundary lubrication prevails. This is normal and acceptable in all steel gears.
What is SAE 90 grade oil?
Petromin SAE 90 Gear Oil Gear Oil (1 L, Pack of 1) Petromin Gearbox Oil Series are high-quality gear lubricants blended from solvent-refined mineral base oils and select chemical additives. They also provide protection against foaming of oil, and wear and rusting of gears. Formulated for automotive high-speed gears.
What is the difference between hypoid oil and gear oil?
The term “hypoid” has more to do with the construction of engine gears than it does with oil. Due to the higher pressure on gears as a result, the lubrication needed has to include ingredients to provide more protection for the gears. This special gear oil is designed not to deconstruct under higher pressure.
What is the GL rating on gear oil?
Gearbox oils are classified by the American Petroleum Institute using GL ratings. The higher an oil’s GL-rating, the more pressure can be sustained without any metal-to-metal contact taking place between transmission components.
What is the difference between hypoid and regular gear oil?
What is a hypoid gear set?
A hypoid gear is a style of spiral bevel gear whose main variance is that the mating gears’ axes do not intersect. The hypoid gear is offset from the gear center, allowing unique configurations and a large diameter shaft. The teeth on a hypoid gear are helical, and the pitch surface is best described as a hyperboloid.
Is Lucas gear oil hypoid?
Yes. Any gear oil meeting a GL-4 spec or higher is a hypoid gear oil. Information on the Lucas website says that this product exceeds all GL ratings.
What is 90 weight gear oil used for?
The 75W-90 gear oil is used under extreme pressure conditions and is recommended for limited-slip differentials and for use in colder climates. Used in heavy duty manual transmissions, final drives and axles, high temperatures will not effect the heavy film left by this oil.
Is 90 gear oil good for motorcycle chain?
It’s perfectly fine to use gear oil for lubing motorcycle’s chain, I’m myself using it for years. Use 90 grade gear oil if you lube every 500–700km while the thicker 140 grade oil lasts for 800–1000 km. Also, there’s no need to clean the chain every 500km. Clean the chain when it’s visibly dirty & mucky.
Can I use hypoid gear oil?
Yes, as long as it meets the specification in the owner’s manual. However, for the best protection, it is best to use a gear oil specifically formulated for marine lower unit applications.
What is API GL-6 gear oil?
The designation API GL-6 denotes lubricants intended for gears designed with a very high pinion offset. Such designs typically require protection from gear scoring in excess of that provided by API GL-5 gear oils.
What is API GL-5?
The designation API GL-5 denotes lubricants intended for gears, particularly hypoid gears, in axles operating under various combinations of high-speed/shock load and low-speed/high-torque conditions. The performance specifications for API GL-5 are defined in the most recent version of ASTM D7450.
What are the recommended lubricant quality recommendations?
The manufacturer’s specific lubricant quality recommendations should be followed. GL-5. Active. The designation API GL-5 denotes lubricants intended for gears, particularly hypoid (see note) gears, in axles operating under various combinations of high-speed/shock load and low-speed/high-torque conditions.
What is the difference between GL-5 and GL-6 lubricants?
The designation API GL-5 denotes lubricants intended for gears, particularly hypoid (see note) gears, in axles operating under various combinations of high-speed/shock load and low-speed/high-torque conditions. The designation API GL-6 denotes lubricants intended for gears designed with a very high pinion offset.
