Fan for 5hp Columbo

[brian]

I just noticed today that when my spindle router sets up a certain resonance(due to direction of cut and RPM)that the cooling fan comes to a stop.As soon as the cut changes to a different direction the fan startes up again.I don't have a lot of hours on this spindle,I'd say less than 100.
Has anyone noticed this happening.Is my cooling fan burning out?

Brian,

This is a serious problem that you need to take care of. Fan problems can result in overheating and shortened spindle life. Contact PDS or Shopbot support.

Yes. Absolutely!!! Stop running the spindle IMMEDIATELY!!!

This is a problem with PDS using a sleeve bearing fan instead of a ball bearing fan. The fan is easily replaced and it's not too expensive. A search on this forum will give you the model number you need and the fans can be ordered from Mouser Electronics. If you can't find it, let me know and I will get it for you.

Thanks for the quick answers.The bushing must be crapping out.
I stopped the fan with the end of a pencil and the spindle router was quiet again(I only ran the router for 1 min.).I hope the next unit lasts a little longer than this one did.
I will contact PDS and see how many arms & legs they want for this unit.

Thanks Brian
