I have had my novak ss5800 brushless system for over 8 months now and i am wondering if i should change the bearings?
I have never really been into the motor so i don't know how many bearings there are, I have been looking everywhere but all that i could find was the endbell bearing and endbell, is that all that i need to replace?

There are two bearings. I haven't replaced my bearings in my original 5800 motor since I got a velociti rotor (which was probably a year and a half or so ago?). The rear bearing is the original (the entire motor is probably 3 or 4 years old over all I think; it came with the original Super Sport ESC).

if you do replace bearings, might as well go for ceramic, I bought my bearings for $7 from rc4less.com

The thing is though, i don't know if you can remove the bearing in the front endbell. You could get a ceramic rear bearing, but novak's replacement includes an endbell with a bearing already in it, which makes me think that the front endbell bearing is not removeable.

You can remove the bearing from the front endbell but you need a bearing press (proper or improvised) to do it. The bearing is glued in so it is not just a matter of pressing it out.

Put the endbell in a vise with some insulation between it and the vise jaws. I have a pair of popsicle sticks I keep around for that purpose. Install the bearing press and put some load on the bearing. You can't really press it out as is because of the glue. Now take a heat gun and heat up the endbell (and bearing). Aluminum expands with heat more than steel. So the aluminum endbell will expand away from the bearing. Plus the heat softens the glue. When it gets warm enough, you will hear a "pop" as the preload from the bearing press loosens the bearing. Use the press to remove it the rest of the way and install the new one with blue locktite.

Yes I used a press to remove and insert my bearings. Carpet fibers are killers.

where can you get these presses?

I got both of mine from eBay. One was Japanese manufacture with Japanese instructions and is made of carbon steel. The other was in a Trinity package (could also be foreign made) but is made of non-magnetic stainless steel and easier to use because the can magnets don't muck with it.

Before I got a proper bearing press I used an old slot car aluminum wheel, a really long 4-40 screw and a 4-40 nut. That worked fine. It is just the proper tool is a little easier to work with.

I managed to get the original front bearing out of my SS5800 without a bearing press or a vice...I think my weapon of choice was a ballpoint pen actually. :D However, it did take considerable effort to get the bearing out, and I bent one of the shields in the process. :roll2: Wasn't the best way to go about it.

you can pop out the bearings with a philips screw driver and hammer,

but i used a 5/8" aluminum rod from the hobby shop to press in

I guess you can use two washers, a 6/32 bolt and a hex nut to press in the
bearing

in this order, place washer, bearing, motor endbell, washer then nut onto bolt.

using a cresent wrench and nutdriver tighten the bolt till the bearing presses in, make sure that you align the bearing into hole.
