## 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
