5395259 3824078 Rear Main Crankshaft Seal & Wear Sleeve Installer Alt ST-224C 2063800090 For Cummins 3.9L 5.9L 6.7L 8.3L & 9.0L For Paccar PX-6 PX-8

Worked effortlessly. 2001 Dodge 2500 5.9 cummins.

Very good quality, I placed seal a little crooked on the crank shaft. Installer corrected slight misalignment and set seal squarely to correct depth. Comes with 4 sets of studs when two would do. Remember to use liquid soap on outside edge of seal. Rear crankcase seal cannot be installed properly without tool, despite what video you may see.

Used on my 93 Dodge with a 12 valve Cummins. I put some anti-seize on the threads to prevent galling, but it worked great. I used the Cummins seal and wear sleeve kit. Tool did not have any problem installing the wear sleeve with seal at a straight and proper depth, for the price it saves you a lot of headache

Definitely need to upgrade the hardware, the threaded studs and nuts are cheap garbage. Do yourself a favor and buy some quality grade A bolts and washers so you don't run into problems.

I used it off the engine and on a bench and it worked perfectly. Idk about doing it on the truck

Excellent tool. Made short work of my rear main seal installation.

Works like it should. Just take your time and let the tool do the work

Item showed up with no hardware. From what I hear thats ok, because the hardware they typically supply is of the poorest quality and doesn't even work. I will have to source my own and I guess thats ok as I was going to have to anyhow. There is a small ding on one of the machined edges I will have to blend out so it doesn't damage my $170 Cummins rear main seal. I am not very satisfied with this purchase due to these quality issues. Not even sure who to place blame upon.
