TCI Automotive Spiral Lock for 745050 and 745000 Two-Piece Pump Drive

This split ring collar allows you to adjust for proper end play in the pump drive after the transmission has been installed on the engine. Simply install the drive hub without the current spiral lock in place and the collar can be secured around the hub and locked into place with the two Allen bolts. This takes all guesswork out of the end play adjustment, and the collar stays secure lap after lap for dependable service. Available as an option for any TCI two-piece drives.
