Dewalt DW618 router operating at continious high speed

While doing a project at my router table, 1/2 round at speed 4, the router suddenly began operating at full speed and it cannot be adjusted to lower speeds with the dial. I fear safety would be a concern. How can I fix this and what is the cause.

I would go to Dewltservicenet.com and in the middle of the page at the bottom type in your model number and you can go to either a breakdown or the instruction manual. On page 6 and 7 it talks about th fine height adjuster. Hope this helps

How do I replace the magnetic ring on DW618?


take out 4 screws on top of router. i used a large flat head but they are not flat head (some kind of combo with star type center). remove top could be a little stuck. you will see bearing in center. the magnetic ring sits underneath the bearing. you need a small bearing/gear puller to get bearing out. once out the magnetic ring goes flat side down over center shaft and then the bearing gets replaced over it. i just tapped the bearing down softly with a small hammer being careful not to break new magnetic ring.

Where do i buy an arbour for dw744 table saw


If you have a type number of 4, an assembly will have to be replaced, not just the shaft. THIS COULD BE DIFFERENT IF YOU HAVE A DIFFERENT TYPE NUMBER. It can be purchased online through DeWalt, but verify your type number before ordering.

Need to replace broken dewalt 618 magnet ring.


you have to take four screws out from top of router. i used a large flat head screwdriver but actually the screw has a weird head like a cross between flat head and star. anyway once you remove cover you should see the bearing in the center. you need to use a bearing/gear puller to remove it. the magnetic ring lays just beneath the bearing. if its still there. mine was in pieces. clean out the mess and then the magnetic ring slides on flat side down. then LIGHTLY tap the bearing back into place. i used a small hammer. there didn't seem to be any lubrication in there so i didn't add any.

I cross threaded the threads on the shaft the arbor fits on and have had no luck repairing the threads - is there an alternative to replacing the motor? The Dewalt shop quotes a $125 fee to fix my...


I would get a needle file, pair of magnifying glasses, recut those threads as best I can, buy a new collet, and get her going. Or, buy the die for the threads, should be about 1/2 28? I know it is a fine thread, the die will be expensive, or take it to a machine shop and ask them to do it. But get the collet first so they can try it. The new armature is expensive, I replaced one once. I bent the armature.

Router will not power up


I wrote a long response to your question, which apparantly has been lost in the web somewhere.
Try to make sure the detachable power cord is properly connected, and twisted 1/4 turn clockwise to lock in place.
Make sure the toggle switch is working freely.
Make sure the collet lock or spindle lock is not engaged.
If that doesn't help, please write back and I'll try to re write a troubleshooting guide for you.
I can't believe it didn't post properly.
Anyway, good luck!

How to open the case in order to replace the bearings


This is a serious disassembly and re-assembly.

Not only do you need to remove the yellow plastic cover end, but also disassemble the collet end. Depending on which version 618 you have it may have screws on the collet end or just a large nut. Sometimes you can't see the screws because they are plugged or covered with wood dust. The bearing is press-fit on the shaft on at least one end and requires an arbor press and special pressing sleeve. So you can only get so far on one of the 618 models then you have to use the arbor press to finish disassembly. The outside of the bearing sits in a very very close fit bore in the aluminum housing, which often becomes very difficult to disassemble without heating the aluminum housing. One bearing (top) must be pressed off the shaft and the replacement bearing precisely positioned where the old one was, so you need to measure with an inside snap gage, a dial caliper tail or depth micrometer to assure proper re-positioning. If you don't get it right then the motor shroud will rub the housing and the shaft won't sit right in the lower bearing.

You also need to replace the brushes while you have it apart. Between the labor, brushes and bearings cost you are better off taking it to a DeWalt service center - but even so, the cost to replace the router would usually be less than the service cost if it is out of warranty! Be very careful to make sure if you or anyone does do this job that the replacement bearings are properly rated for high speed - otherwise you'll be doing the job again in a few months of use.
