How to Replace the Cord and Strain Relief on a Porter Cable Router
This article will teach you to remove and replace the cord and strain relief on your router. This easy repair will help you keep your router running in top condition and help you troubleshoot future r...
Will the 842606 toggle switch listed above fit on my 6902 type 2 router? The nasty dust proof switch it came with died today. I have never liked that type of switch anyway.
Can I use a variable speed control switch on my old 6902 router?? I have some work to do and the speed of the router should be slowed due to the size of the bit.
I have an old Porter-Cable 6902 router which has served me well. It started running very warm along with intermittant vibration so I took it apart thinking the bearings were bad. Not so. I diid a resistance check on the commutator and the readings across all segments was lest than an ohm. All segments to each other read less than an ohm. I don't think this is normal. Can I assume the armature is bad? Thanks.
I am wondering if the fan can be replaced on a 690 router. Something fell down into it and bye-bye went the plastice blades in a hurry. I wonder if the collet chuck threads or pressed of so that the armature can be pull, and a new fan installed?
The chuck is threaded to the bottom of the armature shaft. Removing it is a bit of a challenge because you have little of the armature to hold on to. The easiest way is to use an impact wrench on the chuck. The quick blow from the impact will usually pull the chuck right off. The armature fan is not sold separately from the armature. The armature is part #903660.
I hope this helps with your repair!

Mark,
Thanks for the information. I wondered if the fan was replaceable. In looking at the parts diagram on this website, it does show a replacment fan for the 690, pn 874299 for $10.22. Not sure if this is a the right part, maybe it is a press on item that is pretty dicey...

Hi kredd,
I was just looking at the pictures. I forgot to actually read the words... :rolleyes:
There are many Type numbers and changes to the armature fan but it appears that all of them do change to part #874299. Sorry I tried to steer you in the wrong direction.
Thanks!

Mark, No problem. I did get the collet nut off with an impact wrench and pressed off the broken fan with an arbor press and a split plate to get behind the fan. The new fan is ordered and should be easy to press on. $15 saves an old reliable tool! Necessary in a time of recession....once again, you did help me out, thank you.

Sounds good kredd!
The 690 is the benchmark that all other midsized routers are measured against in my opinion. I have three of them in my wood shop. Not a chance I will ever replace them. I like to keep two of them setup to go with the Leigh dovetail jig. They compliment the Leigh jig beautifully!
Keep us posted on the repair!
Thanks!
