I just bought my first router: a used Porter Cable 690 kit that included a 6931 base. The plunge rod is slightly bent about 3 inches from the top. Can these be replaced, and if so how do I remove it and find a new one?

I would really appreciate any help I can get, Thanks!

Hi Christopher, welcome to the forum.
Looks like both those can be replaced. I haven't a clue how but you can study the parts explode and probably figure it out. You need to know if it is a type 1 or type 2 base. Should be indicated on the serial number plate. The part numbers for the shafts are different on the two styles.
Here is the link, select the type # and it will give you the parts explode and numbers. :D

Thanks John, I really appreciate it. I still can't figure out weather it's a Type 1 or 2. The serial number plate doesn’t specify anything about type, although on the bottom underneath the sub-base imprinted into the metal it says: 699394 2.
I wonder if that 2 at the end is referring to the type or not. I believe it's a 1997 or '98.

Take it back to store you got it from and I'm sure they just replace,or stop by the one of the many PC service center and they will give you a new one..:)

Now that's a good deal,,I think I would still take it by the service center the rods are not that much and have them give it a once over the rods don't get bent on they own,,,it may have been dropped on the rod and you may have other damage that you don't know about...the service center will know what to look for if it's has been dropped on it's head,,,like a crack(s) in the base,motor frame ,etc.

Well, I took your advice and called Porter Cable. He told me how to get it out, the only problem is that the way it's bent, the spring isn't releasing fully and the pin in the screw is stuck. I'm going to give it another try, but if I can't get it I think I'll just take it ACE. Thanks for all your help, I'll let you know what happens.

If the problem is with the part that I think it is, after you get the new part, take a Dremel or hacksaw and cut the rod so it is easier to get out. As for Ace, based solely on my own experience, they may be nice people, but I would not trust them for a router repair.

Well, I ordered the parts on e-ReplacementParts.com and everything fits, but I cleaned out the spring and up into the shaft to remove all of the sawdust and old grease. So now all I need to know is what type of grease should I put back in there? I have, wheel bearing grease, Lithium, and marine grease, but should I use some type of special tool grease?

Hi

You don't want to use the norm grease/oil on the router parts,the grease will act like a dust magnet ,use the Teflon lube type,most are water base and then teflon sticks to the parts to keep the parts lubed up..without building up the dust junk..

DuPont sells a small bottle for about 6.oo bucks ...from just about any hardware outlet...:)
