Porter-Cable Router Bearings

Hi,

I have a dead porter-cable 6912 router, the bearings are shot.
Delta is charging almost the cost of a new router to install new bearings...

Has anyone been able to change the bearings themselves?
Does the job require a press or special mechanical tools?
Does one need to purchase replacement bearings from delta?
What would be the part number?

Thanks for any opinion on the subject!

Agreed!
Look for a bearing supplier if the factory parts are too expensive.
One note of caution here. Routers turn _fast_. If you buy bearings
locally
you will need to get ones rated for the RPMs of the router. The
difference is
primarily in the lubrication used. I had to replace the bearing in a die
grinder (24k RPM) and used a standard greased bearing, the bearing got
so hot
it turned blue!. Tried a bearing lubricated with only a light oil and
all is happy.

Look for a Motion Industries, Applied Industrial Tech. or any number
of independent bearing distributors.

Not necessarily true - most try to design around standard bearings but
some applications may require special internal clearance, special
lubricants etc (but rarely non standard dimensions). Take the bearing
with you to one of the distributors and tell them what it was used on
and they can provide the proper bearing.

Be careful taking only the number to the distributor. Most bearing
races are stamped with the basic part number which does not reference
seals, shields, internal clearance etc. If you get the number from the
shield it will only reference one shield (or seal) as this is usually
the part number for the seal or shield only. In other words, the
bearing may be stamped 6200 and the shield stamped 6200Z but if there
is a shield on both sides, the designation will be 6200ZZ (possibly
followed by C/3 and maybe some other numbers). It's safest to take the
bearing with you to the distributor so they can give you the proper
replacement.

That is about all they should cost.
Find an industrial bearing supplier take the old one with you and they will
match them up.
There is no such thing as propriotory bearings
Tool Manufacturers design their tools around the bearing Industry

I replaced the bearing in one of my older routers. The bearing was
$10.00 and I was able to save this one.

I was lucky to find locally a store that specializes in bearings, yes
bearings !

Yes, Virginia, "Special" dimension bearings DO exist in power tools!
And God forbid if it is special AND metric, or simply rather unusual -
DAMHIKT. This is one reason I tend to buy Delta stuff, rather than
Ryobi and such. In addition to *having* a replacement parts division,
I have yet to see a special bearing in any Delta/PC product I own.
Every bearing I have looked at in my jointer, planer, drill press,
table saw, bandsaw, etc. is a commonly available, generic bearing. I
don't know about the bottom feeder stuff, but the middle and top line
stuff is quite generic. Ryobi and apparently Ridged as well, have no
intention of providing service parts. They consider it disposable.
JMHO,

Should not be a big problem to change the bearings. The part numbers will
be stamped on the bearings and a local supplier should be able to get new
ones for you if the factory ones are too high. Expect around $7.50 each.
Also, on a router or other high speed tool, it is very important to use
bearing mount, a liquid like thread locker, in the housing when
reassembling the tool. If the bearings have went bad there is a really
good chance that they have spun in the housing and the new bearings will
not fit tight enough. You will know this is the case if you put the
machine back together and it is noisy and has a wa-wa-wa uneven sound to
it.

Not on a router, but I changed the arbor bearings on an old Delta TS. There
is a bearing number on the side of one of the races. Take that number to
any local industrial supply that carries bearings and you should be able to
get replacements. The only thing you may need is a bearing puller if the
bearing is press fitted on the shaft. If it is, you can even take it to a
local auto repair shop and likely get the bearings removed cheaply. Mine
were mounted into recesses on the arbor bracket, so I was able to "pound"
them out.
