What viscosity is harley transmission oil

Harley fixed some of these issues in their latest iteration, as techs that have already taken them apart say itвЂ™s a great transmission. You shouldn't have to go 90mph in 6th to avoid lugging, but is sure is fun!ДЄftermarket gurus point out that this is improved in the latest bikes by Harley-Davidson's move to a 103-inch engine and a more aggressive 2.87:1 final drive ratio. Given that the 96-inch motor is judged by many to be under-powered when matched to its a relatively-tall 2.79:1 final drive ratio, the bike lugs in 6th yet makes all that gear noise in 5th (helped but not prevented by V-Twin Trans Fluid). ShockProof gear oils can dampen noise and help gear life in the 2007-09 H-DВ® Cruise Drive 6-speed transmissions, for example, but its straight-cut 5th gear is quite noisy. Lugging your bike, especially a newer model, causes both noise and wear in the transmission. However, the oil cannot prevent everything. This is what causes the rough or missed shifts and our V-Twin Trans Oil helps to fight this, big time. See how the middle gear has wear down the center from the shifter forks? When the gear wears, it causes premature wear to the shift forks-they're hurting each other. Here is that same Big Twin with 70,000 miles, a five-speed bike. The early stock V-Twin gearboxes are not exactly famous for their smooth shifting or quiet operation! That shifting clunk at the stoplight is gone after using our V-Twin Transmission oil, verified by the massive, unsolicited comments on the Internet's most popular V-Twin sites. ShockProof gear oils also cling extremely well to metal, surely a big part of its noise dampening ability and wear control. The fluid really isnвЂ™t that 'Heavy,' as it classifies as a 90W gear oil. By the way, it's the same fluid used in the differential of the world's best Top Fuel Dragsters.ДЄcting like liquid grease, this famous pink gear oil contains a suspension of solid microscopic particles as an extreme pressure agent-its unique solid dispersion cushions gear teeth to help prevent tooth wear and allows the use of lower viscosities. The same product is now packaged as V-Twin Transmission Oil. Many Red Line fans started using this product in its automotive packaging, known as Heavy ShockProofВ® Gear Oil. We are very proud of our motor oils, but Red Line's unique product known as 'ShockProof' is truly a game-changer in terms of its effectiveness in a V-Twin transmission.

It is safe to say that the problem with a compromise is that can't do any one job really well. Since transmissions don't have to deal with the byproducts of an internal combustion engine, wouldnвЂ™t you select gear oil with chemistry that is optimized for the conditions? The same goes for the primary case. Why is it wrong to just use motor oil in the transmission? Simply put, motor oils contain additives specific to keeping contaminants in suspension. Much of this can be avoided by using Red Line V-Twin Transmission Oil with ShockProof. Here you see blue - the sign of high heat - on the gear and wear in the center of the teeth-this bike has been running Syn 3. All of the power goes from the engine to the transmission and through to the rear wheel through this gear. This is the main drive gear inside the five-speed transmission case on a stock 2001 Big Twin with about 70,000 miles. Using a higher-quality, fully-synthetic 20W50 motor oil, a proper synthetic gear oil for the transmission, and a specific synthetic primary case gear oil optimized for the clutch and chain makes more sense for most motorcyclists looking to protect their investment and enjoy these bikes to the fullest. Just because the dealership can manage its inventory more easily with one oil type from the factory doesn't make this one product the best choice for your bike. Most experts and educated enthusiasts will tell you not to use a motor oil in all three compartments.

Lubricants are a huge topic of debate in the V-Twin world, often focused on a simple question, 'Is it the best way to follow the dealer and put a motor oil in my engine, transmission, and primary case, when I could get the correct product for each application?' After all, most American V-Twins are unique in that the engine, transmission, and clutch are lubricated through three separate systems. For Sportster and Buell riders, Red Line has found Lightweight Shockproof (not shown) to be highly effective. Three of the most popular Red Line products for V-Twin motorcycles include V-Twin Primary Case Oil, Motorcycle 80W Gear Oil with Shockproof and V-Twin Transmission Oil with Shockproof.
