• This tool will help with the installation and re-sizing of the 4L80E & 4L85E Turbine Shaft Seals.
• Works with all input shaft lengths.
• Simple to use and the re-sizer prevents improper installation and damage of the seals.
• Made of steel and will outlast the more common GM Kent-Moore plastic tools.
• 3 piece Tool Kit comes with the Universal Seal Expander for both ends, the Small End Teflon Seal Re-Sizer and the Large End Teflon Seal Re-Sizer.

• Properly remove the old seals, make sure all seal debris is removed from each groove.
• Lube the grooves, new seals, and tools with trans-gel.
• Expand the seals for the small end first to the proper ID
• Center the new seals in the grooves and gently apply finger pressure to ensure the seals are inserted into the grooves.
• Slide the small re-sizer over the seals using the LONG TAPERED END first, this will ensure the seals are gradually seated into the grooves
• NOTE: using the short tapered side first may cause the seals to roll out of the grooves and permanently damaging them!!!
• Let the re-sizer set the seals for at least one minute, then flip the re-sizing tool now using the SHORT TAPERED SIDE to insure both seals are properly sized.
• Repeat the same steps for the large end making sure all grooves, seals and tools are properly lubed with trans-gel before installation.
