Need to fix a PC 7518
Posted: Sun Mar 14, 2021 12:36 pm
I followed the "cry once" philosophy and dropped some hefty change on a PC 7518 router for my home shop. I make a raised panels doors for cabinets and various other projects, but I am not a production shop. Sometimes the router takes a break for months, then gets back to work for a few hours over the course of a week. Overall, it's pretty light use for this workhorse. All my research at that time seemed to point to the PC7518; I figured that I'd have it for the rest of my life. I have other routers for handheld work, this one is just for my table with a Woodpecker lift.
5 years ago the speed control crapped out. I was a little surprised and then quite annoyed that the replacement part was so expensive.
This weekend, the speed control died again. Just like last time; it was fine when I used it a few weeks ago, as soon as I turned on the router yesterday it was hunting all over and couldn't decide on a speed.
This time, it appears that the replacement part is no longer available. From some sites, it seems that the router might even be discontinued. !!!
I've been reading about replacing the capacitors for the speed control. Sounds simple enough. I've replaced capacitor and other components to fix TV and other items.
But the other places I've read about this, I've seen that I'll need a couple of 22uF capacitors, originally rated at 25V but some recommend upgrading to 35V.
Um, that's not what I'm finding. The speed control in my PC7518 has 2 radial capacitors. One is 47uF/50V and the other is 4.7uF/63V. I have found these through suppliers online. (can't find anywhere local since Fry's closed and Radioshack is rare).
Just checking: has anyone here done this? Does it sound like I'm looking at the right capacitors?
Any help is appreciated. It would be really stupid for this 7518 to become a paperweight. The other option, if I can't get the speed control fixed, is to bypass it altogether and use an external speed control. I'm wary about losing the load-compensating 'smarts' of the original controls. Definitely open to suggestions.
