## Questions & Answers

**Q: Where can i find the tools to install the wear seeve and gascket?**
A: Seal installation tool comes with the kit. Loctite 660 retaining compound will secure the sleeve if it ends up being a non-interference (press) fit. A company with a generic installation video can be found on Youtube...they sell a nice sleeve-installation tool. Can't think of them right now, but they're easy to find. I will machine my own.

**Q: Will this fit a 1997 8.3 Cummins**
A: no ,it won't fit

**Q: Which side does the rubber seal go? I’m guessing outside**
A: Best thing to do is watch a YouTube video over it that’s what I did and the seal goes on the outside if I remember correctly

**Q: Will the part fit a 6.7?**
A: Yes ,it will

## Customer Reviews

### ⭐⭐⭐⭐⭐ Seals
*by S***S on January 25, 2025*

Part fitment is great it comes with a seal installer which makes installation a breeze! Not had any issues with any leaks and this is much cheaper than a part from Cummins.

### ⭐⭐⭐⭐⭐ Great Value
*by D***R on August 5, 2025*

Item as advertised. Installed very easily. Also, of note, you do not need to purchase a separate seal driver with this item. The included driver worked fine.

### ⭐⭐⭐⭐ Direct replacement
*by  ***N on July 7, 2024*

Install was straight forward. They seem to be holding up just fine. I haven't had any leaks. I have 40k miles on it and no complaints. I was a bit skeptical when ordering but no worries they are just as good as oem so far. They fit as well as the oem.
