What weight is Harley Davidson Fork Oil?
Standard type E fork oil is supposedly around 7 to 10 weight, regular SE approximately 20 weight, and the heavy duty racing SE is around 30 weight.
Can I change fork seals without removing forks?
Yes. Pull the bolt out that secures the cartridge to the lower fork leg and the forks will come apart. Put a seal in with a split type fork seal driver. Then you pull the cap and separate from cartridge to pull the spring to set the fork oil level.
What happens if you run out of fork oil?
The longer your fork seals leak, the more oil that drips onto your front wheel below. The fork oil will also begin leaking onto your front brake pads and calipers. When your brakes become too lubricated, their ability to stop your front wheel when you clamp down on your brakes is practically non-existent.
What happens if you don’t change fork oil?
Premixer112. You will loose oil in the forks and they will contiually leak worse. The more oil you loose, the worse your forks will peroform. Not to mention that all of the bushings and internal parts will be wearing at an extremely increased rate.
Why should we change fork oil?
The oil serves a couple of purposes in your forks. It provides lubrication for the sliding parts, keeping them from wearing metal to metal. The oil also provides your damping. The viscosity of the oil will break down over time and produce less damping action and needs to be replaced because of this.
What is the point of fork oil?
To answer that question with clarity, it helps to understand what oil does in your mountain bike’s suspension system. Fork oil has two functions: lubrication and damper compression.
How often should you change fork oil on a Harley?
How often should you change your fork oil? That is a very good question. It’s been quoted as every year, every two years, every 30,000 miles, every 50,000 miles and more. The best thing is to check around or ask Mike the Harley Mechanic expert.
Does fork oil brand matter?
Some will claim that fork oil is just fork oil, and any brand will offer the same performance. Consider this before buying another brand: There isn’t a standard viscosity index similar to engine oil. Brands that offer similar characteristics at 40ºC will feel comparable in performance.
Does fork oil weight matter?
Fork oil viscosity matters The fluid’s viscosity (often thought of as its thickness) influences how fast or slow the oil flows through the shock valves. If you prefer quick rebounds, use a lighter fluid. If you like slower rebounds, use a heavier fluid.
How much fork oil do I need Harley Davidson?
Measure 11.2 fluid ounces, which is 300 milliliters, of Harley Davidson fork oil or the equivalent into a measuring cup. Pour the fork oil into the top of a dry FLH fork from which you have removed both the fork cap bolt and the fork tube plug but not the fork spring.
Can you mix different weight fork oil?
yes oil can be mixed, BUT : only the same brand and type of oil, preferably purchased at the same time to make sure the batches are close in composition too. Also this oil works for single viscosity oil (such as 10W), not engine oil such as 10W40 mixed with 15W50.
