Seals And Gaskets

O-rings, Seals, Gaskets and Oil

• Always replace the O-rings, gaskets and seals.
• After removing gaskets and seals, examine the contact surface on housing or shaft for burrs resulting from removal or for other signs of damage.
• Coat the O-rings with ATF before inserting to prevent the rings from being crushed during assembly.
• Only use ATF. Other lubricants cause malfunctions in the hydraulic transmission control.
• Lightly coat the seals with ATF along the outer circumference and on the sealing lip -arrow-.
