## Questions & Answers

**Q: How long is the shaft? 1-3/8" or 1-7/8"?**
A: I can see why MegaDepot thought 24mm was the answer, however it is not - the confused the diameter with the length.  The L on this stands for long shaft, typical shafts are 30mm in length.  In this pump the L = 45mm shaft length.  The diameter of the shaft is 24mm.

**Q: Your listing says it is a 1450 rpm pump, but the same pump on the ar website is listed as a 1750 rpm pump. is the 1450 correct?**
A: should be 1750

**Q: Would this work on Honda Gx390 pressure washer?**
A: You will have to contact info@arnorthamerica.com and please provide specifics on your pressure washer.  PSI, HP......  Thank you.

**Q: Does anyone know the length between the bolt holes**
A: Length 5” w3”3/4
