The tool to set seal to proper depth!! 5.9 Cummings crank seal install tool
Easy to use, great install tool to get my crank seal installed and to proper depth. Nice tool added to my reusable collection for future repairs.

For 24 v 5.9L Cummins, perfect.
Used this on my cummins, installed the sleve perfectly.

Very functional tools work well
Worked great. I would put washers on the bolts so they don’t bite into the body of the sleeve install tool. Both work for the DIY guy. I would recommend

It’s ok I guess
The wear sleeve installer part of this set works great. The other one, the piece you’re supposed to use to hammer on to drive the seal into the cover, isn’t sized correctly. I ended up making my own seal installer on a lathe. Maybe this tool is sized for another brand of seal. Your experience may vary. Good luck.
