Royal Purple final drive gear lube?
« on: April 07, 2015, 06:06:06 pm »
$15.54/qt

I want to have everything ready to do my first oil change, along with a flush/fill for the final drive, this synthetic seems to be priced right with Amazon Prime shipping, what's everyone's thoughts or what are you using?

Rick,
I just use regular Bel Ray 80-90. I will be changing it frequently enough that synthetic doesn't make sense. 10.00 will get you at least a half-dozen changes.

What's HYPOID?


UPDATE:

Nevermind...the power of GOOGLE:

What Is Hypoid Gear Oil?

If you work with motorcycles or perform your own transmission fluid changes, you will have been introduced to gear oil and specifically hypoid oil at some point in your mechanical learning. That said, most people have no idea what hypoid oil is, much less what it is used for. Have a question? Get an answer from a mechanic now!

    What is Hypoid?

        The term "hypoid" has more to do with the construction of engine gears than it does with oil. Early automotive engineering involved gears that meshed with each other straight on. When you think of gears, this flat face-to-face gear teeth approach is what we learned as kids in cartoons and marketing images of big machinery. However, automotive design soon figured out this gear approach was inefficient and also very loud when running. Thus, the "hypoid" design was invented which basically has two gears shaped like Christmas trees mesh with each other at 90 degree angles or similar.
        The hypoid approach reduced gear-meshing noise and it allowed greater torque pressure for stronger drive. The design was so successful every car and vehicle today uses it as a standard transmission design. 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.

Direct quote from the manual:

Final Gear Case Oil
Grade: API GL-5 hypoid gear oil
Viscosity: When above 5°C (41°F) SAE90
           When below 5°C (41°F) SAE80
Oil level: Filler opening top
Amount: about 160 mL (5.41 US oz.)


I've been using regular marine lower unit gear lube for years, which is also GL-5 rated.  My Mercury outboard uses more than the bike.  And since it gets to operate underwater, it gets changed every year (and sometimes more than once).

Hi,
       I don't think it matters what you use as long as you do change it!!!

 I was quite surprised by how dirty my final drive oil was after only 4,000 miles! ;D

 It WILL be changed with the engine oil, everytime!!! :great:

15 bucks is a little steep, but for how often you actually have to change the pumpkin, what the heck?  I use Amsoil Gear lube, which was closer to $12/qt.  I noticed a change in how long it can coast since changing to this. That means better fuel mileage. :))

Go straight to the Amsoil website, and for a very small fee you can become a dealer, or go to a store that carries it.
