O-Rings, Seals and Gaskets

O-RINGS, SEALS, GASKETS

- Always replace O-rings, seals and gaskets.

- After removing gaskets, examine the contact surface on the housing or shaft for burrs or signs of damage related to disassembly.

- Apply a thin coat of petroleum jelly to O-rings before inserting in order to avoid the rings being squeezed when being installed.

- Apply a thin coat of petroleum jelly to the outer circumference and to the sealing lip of sealing rings for installing.

- Always use only a small quantity of petroleum jelly. Other greases cause operational problems to the hydraulic transmission control.

- The open side of the seals faces toward the sealing fluid.

- After installing, check level of gear oil or ATF and adjust to correct level, if necessary.
