How Much Oil Goes in a Harley Primary?


If you’re wondering how much oil goes into a Harley primary, don’t worry! It’s actually quite easy to determine the proper amount by checking the manual. Harley Davidson actually formulates its own primary oil, which meets the highest standards for transmissions and primary chain cases. The oil is a heavy synthetic formula designed specifically for frequent two-up riding and extreme temperatures. You can use the same oil in your bike, or choose another type.

In order to properly service your motorcycle, you must use the right type of oil. For Harley-Davidsons, synthetic oil is recommended. It doesn’t expand and can keep your bike running well for a long time. You can see the amount of oil in the dipstick by half-a-degree intervals between the full and add marks. Using the wrong type of oil can damage your engine, and it will also cost you money in repairs and replacement. The first thing you must do is check the oil level. After checking the oil level, you can add more if necessary.

The recommended amount of oil for a Harley shovelhead is four quarts of SAE 50 or 60 engine oil. In addition, you should use 1.5 pints of HD transmission lubricant. Some people use 75w90 gear oil mixed three-to-one with Lucas oil. Shovelheads are also made with two different types of fork oil. The types of fork oil are HD Hydra-Glide for models from 1966 to 1969 and HD Type B for 1976-75. You should use a quart of brake fluid in your Harley if you plan on braking.

There are two general rules to follow when filling the primary of your bike. First, you want to make sure the oil level is between twenty-four and twenty-eight ounces. You should also keep in mind that the manual will recommend filling the primary to a certain point. You can either fill it to the level that is indicated on the manual or until the clutch diaphragm spring is pressed into place. In either case, you don’t want to fill the primary to the point where it’s too full. Secondly, too much oil is going to drag the plates and cause your shifting to be a bit harder.

The best motorcycle oil to use for your Harley’s primary is Mobil 1 Racing 4T 10W-40. This motorcycle oil is recommended for all four-stroke engines and is a preferred choice by many of the world’s largest motorcycle rallies. Its high quality and low cost also make it a smart choice for Harley owners. A good motorcycle oil can help keep your motorcycle running smoothly and keeps repair costs to a minimum.

If you are wondering, “How much oil goes in a Harley primary?”, you’re not alone. There are a few different types of motorcycle oil and it is best to check with your manufacturer for specific recommendations. Harley Davidson recommends Mobil 1 Racing 4T 10W-40 oil for their motorcycles. This oil is formulated for the primary drive of a Harley Davidson motorbike. It is designed to protect your bike’s engine, reduce wear, and heat, and keep the motorcycle clean and free of corrosion during storage.

While many motorcycles use a shared sump, Harley-Davidson uses separate sumps for their transmission, primary chaincase, and engine oil. This ensures maximum protection and flows better when the engine is cold. It is expensive and hard to find, and you’ll need the right tools to properly lubricate all three components. However, if you’re unsure about what oil is right for your bike, you can always use a product specially formulated for this purpose.

Amsoil SYN 3

AMSOIL SYN 3 is a synthetic motorcycle oil approved by Harley-Davidson for all stages of engine life, including break-in. It will not negatively affect the warranty of your bike and will not interfere with the engine’s break-in cycle. Unlike other synthetic motorcycle oils, AMSOIL SYN 3 does not require flushing during servicing. This oil will run cooler, quieter, and shift more easily. It is also compatible with the primary chain-case and transmission, which makes it an ideal choice for all three components of your bike.

While motor oil and gear oil are measured differently, gear oil is largely similar to 10w-40 motor oil. If your primary is not friction modulating, you can use 75W-140 gear oil. For motorcycles, AMSOIL V-Twin Synthetic Transmission Oil is SAE 110. It is manufactured for Harley-Davidson motorcycles, and is formulated to meet the needs of motorcycles running in hot climates.

AMSOIL Synthetic 20W-50

The AMSOIL Synthetic 20W-50 Motorcycle Oil is a highly recommended fluid for Harley-Davidson transmissions and primary chain-cases. This motorcycle oil is compatible with both conventional and synthetic motor oils. However, mixing different oils can shorten their life and reduce their performance benefits. Also, you should avoid mixing AMSOIL Synthetic 20W-50 with other aftermarket oil additives. The recommended drain interval for Big Twin Harley-Davidson transmissions is 20,000 miles. The AMSOIL Synthetic 20W-50 is compatible with standard transmission oil drain intervals.

AMSOIL Synthetic 20W-50 Motorcycle Oil is an advanced multi-functional lubricant formulated to meet the needs of domestic and foreign motorcycles. It outperforms conventional motorcycle oils in most areas. AMSOIL, the first synthetic lubricant manufacturer, is the leader in motorcycle oil technology. In 1972, it produced the world’s first API-qualified synthetic motor oil. Since then, AMSOIL has been “The First in Synthetics”TM and continues to set the standard.
