REPAIR REV: 05/99 Assemble outboard pistons
13.Coat new fluid seal with brake fluid. Ease seal
into groove in bore using only fingers, ensuring it
is properly seated. Fluid seal and groove are not
same in section, so when seal is seated it feels
raised to touch at edge furthest away from
mouth of bore.
14.Coat appropriate piston with brake fluid. Insert it
squarely into bore by hand only. Do not tilt piston
during insertion, leave approximately 8mm
projecting from bore.
15.Coat new wiper seal with brake fluid and fit to
new seal retainer. Slide assembly, seal first, over
protruding piston and into bore recess. Use
piston clamp to press home seal retainer and
piston.
