Fork Oil Filling Quantities (per side)

In the charts you will find a summary of the fork oil fillings of various models.

All data without guarantee.

Footnotes:

  1. Wet means on an oil change.
  2. Dry means, the fork was completely disassembled, cleaned and dried.
  3. Fork oil level is determined from upper edge of fork tube (Refer to manual for exact procedure)
  4. These models have drain screws. Despite this fact the manual speaks of complete removal and upside down draining of the fork tubes. (Refer to manual for exact procedure)
  5. Fork has no drain screws. Disassemble fork for oil change. (Refer to manual for exact procedure)
  6. The manual does not specify "dry" capacities, but gives the same capacities for oil change and complete fork overhaul.

PanAm Clean-Funnel
PanAm Clean-Funnel
A good funnel is a must have in any workshop when it’s time for an oil change or a refill. The annoying part of these jobs was to stow away the oil dripping funnel into a dark corner where you would find it a few months later contaminated inside-outside with dust, bugs and other debris. The PanAm funnel puts an end to this problem because it features screw-on caps at the top and bottom which can be removed for action and which keep the inside of your funnel perfectly clean during storage. The flexible spout makes it more versatile as it allows to direct the funnel tip in tight spots.

Bel-Ray Fork Oil
Bel-Ray Fork Oil
It's that time again – the fork oil needs to be changed.
But why actually? Because like any oil, deteriorate and loses its properties over many kilometers on your Harley. Fork oil not only lubricates the fork bushings and fork tubes and reduces friction, it also controls the compression and rebound of the suspension.
Our Bel-Ray fork oil demonstrably reduces this friction – thanks to specially developed and relieve fork tube restraint.
The three available viscosity grades allow for practical tuning:
SAE 30W was the standard fill for all models until 1978, and even until 1984 for FL models. This variant provides firm damping, especially for heavier machines., SAE 20W was introduced afterwards as the new standard fill – for a balanced fork characteristic with a good compromise between comfort and control., SAE 15W offers a slightly softer response and is suitable for lighter front ends or a comfort-oriented suspension setup.,
Bel-Ray fork oils are fully mixable, allowing for individual viscosity adjustments.
