5. FAQ

Q: Is the bushing main function to seal in oil?

A:  Let me give you a professional answer. Its core function: It's not for sealing, but for support. It has high hardness, and its main functions are:

• Bearing lateral forces: Preventing the piston rod or piston of the hydraulic cylinder from bending or directly rubbing against the inner wall of the cylinder during movement due to force.
• Maintaining concentricity: Ensuring the piston or piston rod moves centered within the cylinder, avoiding uneven wear.
• Wear resistance: Providing wear-resistant surfaces for relatively moving metal parts (such as piston and cylinder), protecting the metal components.

Q: In which position is the gasket used?

A:  In transmissions, these gaskets are primarily used for:

• the mating surfaces between the transmission housing and the valve body;
• sealing between the oil pan and the bottom of the transmission;
• sealing various side covers and end covers.

Q: What is the function of this brass rings in the transmission seal kit ?

A:  The primary function of the brass rings (specifically synchronizer rings or blocker rings) in a grader's transmission is to synchronize the   rotational speed of the gear you are shifting into with the rotational speed of the shaft it needs to engage.  This ensures a smooth, quiet, and non-   destructive gear shift.
