After disassembly and completely dry:
426 ±2 mL (14.4 ±0.07 US oz.)
If necessary, measure the oil level as follows.
Hold the inner tube vertically in a vise.
Pump the inner tube several times to expel air bubbles.
Using the piston rod puller [A], move the piston rod [B] up
and down more than ten times in order to expel all the air

Special Tool - Fork Piston Rod Puller, M12 × 1.25: 57001
Remove the piston rod puller.
Wait until the oil level settles.
With the fork fully compressed and the piston rod fully
