Dewalt Router .... Bearings?

[NOTTNICK]

I've just been routing some oak boards and my DW624 started making a different noise and ran very hot.
After leaving it for a long while to cool, it still spins but is noisy.

I am guessing that it is the bearings that have gone.

I just thought I'd double check here in case someone else had experienced this and found it to be something different.

I just watched a YOutube video showing self replacement. It looks like I might be better off going to a service centre - it seems to be quite a complicated procedure. Again, can anyone comment on this?
Cheers

Sounds like bearings to me and replacing them yourself will be loads cheaper than sending it to a dealer.

I suppose it depends how confident you feel as to whether or not you do it yourself. Here's an exploded diagram of a DW624 Type 2 (don't know what type yours is - it will be on the rating plate).

There are two bearings - one at the top and one at the bottom. Both seem to be reasonably easy to access, although you'll probably need a bearing puller.

I did the bearings in a MOF177 with out a puller, and its a very similar router.

Are you in Nottingham? I could give you a hand doing them.

I see you are from Nottingham!

Turn the shaft by hand and if it is stiff then your bearings are knackered.
Get some from Ebay pop round and I will help you fit them.

Get the bearings out and take them to a bearing supplier. Get the best available, they aren't very expensive. My local bearing guy said Dewalt couldn't have found any cheaper bearings if they tried! Your local service centre will tell you that its cheaper to bin it and buy another one than pay them to fix it. Its a shame because Dewalt used to be the industry standard for lots of tools but especially routers. Nowadays they let the accountants design them.

Router bearings are a consumable. All bearings have a design life and 20,000 rpm gradually uses this up. A good router is quite capable of going through several sets of bearings over it's life so it is a useful skill to learn how to replace them yourself and not very difficult.

As others have said, go to a bearing specialist and buy good quality bearings by NSK, ***, SKF or the other leading manufacturers. Replace both ends as you may as well while it's apart.

Be carefull pulling the small bearing off the top end as the armature / spindle is thinner and they can be damaged by bad technique when removing the bearing. A bearing puller with slim claws is a good investment and will let you do the job safely. The saving you make by doing the job yourself will pay for it the first time out.
