HL 850 E Has 100,000 LFT NEED'S ARMATURE BEARING

[counterfix]

This hl 850 e has preformed great over the years but it has finally seized its armature bearing and rather then send it all the way to Indiana i will replace it in a few short steps.

first i want to remove the two screws on the brush plate then the two that's holding the bearing flange

know i can remove the plugin brackets by lifting them up with pliers and brushes have two screws

then lift the brushes up and out like this

now i can remove the cover for the tooth belt and take it off there are four screws holding the bearing flange to the planer housing
remove them and now separate the bearing flange from the housing like this

you can know unscrew the tooth disk from the armature clockwise then the armature is free like this

the tooth disk is the small gear on the armature. use a bearing puller to remove the bad bearing then press on the new one

now just reverse the steps to reassemble the nice thing about festool is the bearing ring is rubber when the bearing freezes it
won't destroy the housing ;D after your finished run the tool for a few minutes to seat the brushes know i can do another 100.000 LFT.

Great post [thumbs up]

I love seeing picture essays of near taboo subjects.

showing the inner workings of a  is like showing an ankle in Victorian England

showing disassembly and repair is "Hard Core"  [scared]

I am guessing no one is posting on it because they are afraid of tool prudes saying you will "void the warrenty" or you can "ruin the tool" and let a certified repair specialest "resolve the problem"  Never mind the tool has worked more wood than a ---- ---- .

Once again  Great post

It's always great to see someone document their work!  I may do the same if mine was out of warranty.  I bet he had the skills and couldn't deal with not having his tool, obviously it does alot of work for him.  Good information!

I have found that here in this `disposable` world, many guys will cut the cord (helps limit liability) and toss the power tool in the dumpster. For the cost of the default (read: DeWalt) tool, it generally will have paid for itself before a broken one could complete the repair cycle. Of course I am not talking about Festools.

IMHO the average tradesperson is more than capable of replacing nearly any part in any tool of their kit (assuming no special tools are required). In many ways they understand their tools better than the manufacturer. Maintaining/repairing a power tool should never be a `warranty voider` assuming the repair was done properly with direct replacement(OEM) parts.

Thanks Craig this thread was for infomation bearings are the one thing most likely to fail on any tool
so anyone can do the replacement and doesn't necessarily void the warranty. how ever if its assembled wrong and then ran and causes damage to the tool that most certainly can void any warranty. [jawdrop]
its not wrong to work on the mechanics of a tool but i would be Leary of doing anything to the electronics.
