Degreasing
W A R N I N G Cleaning solvents can be toxic and volatile. Use only in
well ventilated areas. Avoid physical contact with sol-
vent and do not inhale vapors. Keep solvent containers
covered when not in use.
C A U T I O N Before stripping parts, remove all fittings, O-rings,
nuts, bolts, washers, pistons, bearing cups, etc.
1 Clean all metal parts by immersing in a clean degreasing
solution. An alkaline based solution is recommended
for aluminium and magnesium parts.
2 Hardened dirt or grease may be removed with soft bris-
tle brush, or by soaking in cleaning solution.
3 Where necessary clean bearing cones carefully in a
separate container of clean solvent.
C A U T I O N Do not spin bearing cones with compressed air.
4 After cleaning, thoroughly dry all metal parts with fil-
tered, dry compressed air.
5 It is recommended that all O-rings, backup rings, and
wipers be replaced at each overhaul. However, if neces-
sary, O-rings may be reused, but should be put back into
position from which removed.
6 Wipe down O-rings, backup rings, wipers, or other rubber
parts with a clean dry cloth. Lubricate with a suitable O-
ring lubricant prior to installation.
