Center Support: Assembly

NOTE: The piston return spring, snap ring or snap ring retainer from the low/reverse clutch side of the center support are not interchangeable with the forward clutch side of the center support. When assembling the center support, be careful not to mix the components from the low/reverse clutch side with the forward clutch side of the center support. Failure to assemble the center support with the components in the correct side will result in damage to the center support, low/reverse or forward clutch.

Clean and inspect the center support for damage. Install a new center support if necessary.

NOTE: The forward clutch piston in the center support is the side of the center support with the short legs.
