Product Review

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.
This 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.

Simple to use Instructions:
1. Properly remove the old seals, make sure all seal debris is removed from each groove.
2. Lube the grooves, new seals, and tools with trans-gel.
3. Expand the seals for the small end first to the proper ID.
4. Center the new seals in the grooves and gently apply finger pressure to ensure the seals are inserted into the grooves.
5. 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 damage them!!!
6. 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.
7. Repeat the same steps for the large end making sure all grooves, seals and tools are properly lubed with trans-gel before installation.
