Well armed with advice from FOG experts, I embarked on rebuilding my router spindle. I had acquired it used and it ran very hot and had a tinny sound. Suspecting that bearings are shot, I decided to replace them. For starters this is what the?spindle looks like and the first job is to remove the spanner nut holding the bottom bearing assembly. It is the brass colored thing in the pic below.
I am sure one can buy a proper socket but most I saw online were for a specific task. Not only were they expensive,?they also?did?not provide the?detailed dimensions of features. I was not sure if I would find one that met all specifications so I decided to just make one. 1-5/16" 12 point socket was the best candidate. Be aware that you may only find sockets that take a 3/4" wrench in this?size. It took about an hour to?make it, which included final?grinding of pin?sides and pin thickness for proper?fit, so not too bad.
Following is the process I used. I scribed a line from the socket?end 9mm down around the circumference - depth of pins. Then I cut painters tape in 5mm width and placed it in line of the inside hollow of one of the 12 point, then up and over the end to the outside. This created the shape of the pin I needed. Then repeated the same thing 3 more times skipping 2 hollows. The 12 point socket made it really easy to locate the pins at 90 deg to each other. Using grinder with cuttoff?wheel, I cut on each side of the blue tape to the scribe line and then along the scribe line between pins. The cutoff wheel was too large to complete this cut without cutting into the pins so I finished with dremel. Finally, I needed to grind the inside high spots between 12 points as shown in pic above (red lines).
Various attempts failed to secure the spindle in my vise (6" long jaws), where it would not turn while attempting to remove the?spanner nut. I even wrapped an old bike tube around the two collars. I was told that I needed proper jaws instead of my homemade wood liners but in the end the method my neighbor came up with worked like a charm. He cut steel bar that would fit in the slots of the lower collar but was wider than the slot depth. Vise just clamped onto these steel bars and that worked. Here are a few pics of my failed attempts?and a facsimile?of how it was successfully held - just imagine the right pic upside down. Also the 8" long jaws of neighbor's vice allowed for the spindle to be held vertically on one end of the vice jaws without interfering with the vice itself. We had to use an impact wrench?to get the?spanner nut loose.
Next step was to loosen?the top nut. I could not find a spanner wrench specifically for 44mm - McMaster offerings skip 43-44mm but does offer one for 1 3/4" with a pin, not hook. So I purchased the set shown below and the smallest wrench is for 38-42mm. I first tried a dead blow hammer but no luck. My neighbor had a pipe that went over the wrench and with all my might it came loose.
If you did not know, the bearings on the router spindle reside in a casing. It was recommended that I get bearings with C3 clearance because, I think, the concern is that the shaper spindle casting clamps on the outside of the bearing - presumably resulting in reduced clearance. While this is true for the 30mm and 1.25" spindles it is not for the router spindle. I did get mine with C3 clearance (SKF Explorer 6006-2Z/C3GJN) and I can actually feel the movement in the bearings, so I hope they will be okay. The bearing I purchased is shielded - 2Z, on the bearing PN, signifies this. I did this because they are widely available and the shield can be removed easily with a pick tool. However, there can be other?issues buying a shielded bearing, more on this later.
This bearing has a limiting speed rating of 17K RPM and reference speed rating of 28K RPM - this was confirmed by calling SKF as I found conflicting data on their own websites.?I noted after purchasing the bearing that it has polyurea grease and contacted SKF to determine if it is compatible with the lithium complex EP (Shell Gadus S3 V220C 2) grease I currently use. It is not, so my choice was to clean it out completely or continue to service with polyurea grease. I chose to stay with polyurea as it is supposedly a newer grease that is widely being accepted for certain applications. I learned a lot with this exercise. Although I tried to be thorough, the grease was something I never thought about. This bearing is for motor application. It is shielded and I believe that is the reason it came with that specific grease.
Anyhow, old bearings came off very easily with a puller. So easy that I saw them move while snugging?up the puller, so I did not need to secure the spindle in the vice. Oh, bought a 3 pc puller set from harbor freight for $25 and used the?6" puller.? ?Here are pics of a bare spindle, new bearing with one shield removed, bearing case halves and the puller in place to remove the top bearing.?
I cleaned the bearing surfaces on the shaft with maroon scotch brite and then polished with gray ultra fine. There were a couple of marks on the upper bearing surface that came off easily.
I had several options to install the bearings but I chose to place the shaft in the freezer (0F vs 18F outside) overnight. I progressively increased the bearing temp to 200F in the oven. Enlisted my wife to hold the spindle upside down and I installed the bottom bearing. It seated with aplomb - no drama,?quite a satisfying?experience. I had placed both bearings in the oven and was concerned about leaving the 2nd bearing in for too long (likely unfounded concern), so I tried placing the top bearing after the spindle was in the freezer for 45 mins. I noted that the bearing inner race was touching the threads on the spindle as I lowered it. Well it went in a little and got stuck. Earlier, I had asked my friend to drop his bearing press as a backup, so I proceeded to remove the bearing with the puller and then installed it using the press. It went super easy and after this experience, I would use the press versus messing with hot/cold, unless the application called for it. I guess I will never know if the top bearing would have gone in had I cooled the spindle thoroughly. Below are?pics showing the bearing being pressed. BTW, the shaper spacer rings work well for pressing on top of the bearing - grease zerks not yet installed to provide clearance for the spacer rings. Pic of spindle with bearings installed. Finally, a close up of the assembled bearing case showing that there is about 3/16" space for the grease to escape.
I decided to replace the top and bottom locknuts. Top locknut was damaged due to my exuberant hammering (I think still usable). Bottom one was okay but was under $5 so might as well. Felder only had the bottom one in stock so will be a month before I see it. If there is any significant learning or update I will add to this thread. I hope anyone needing to do this in future will find this info useful. Should more info be desired, I have added links to FOG threads where I asked for advice on this process.

Well got the top and bottom locknuts from Felder. Tried the spindle and bearings don’t seem to be getting hot but I have an issue with the belt. In another thread where the issues with the spindle were discussed, it was shared that the bottom rib sheared off of the new belt I got from Felder. Well same thing happened with the new belt which was a D&D belt I bought online. I am no longer sure if the first belt was damaged due to bad install. The belt is tight but the flex seems comparable to the std. shaper spindle. Here are 2 short videos showing how much belt flexes under ~equal pressure. Should I reduce tension on the belts. I will also call felder tomorrow. How can I determine if there is miss alignment between spindle and motor pulley? As I write this, maybe a measurement comparison of the shaper spindle with router spindle can give me an idea. BTW, the damaged 8 rib belts appear to run okay if I position the missing rib on top. Not sure, what would be wrong if I just use these belts. Imran

??I raised router spindle with shims on bench to align its bearing with shaper spindle and the belt location looks good. Just a visual check.
Called Felder. No known similar issues per the tech. Since, the belt runs fine flipped he suggested I use it that way for a short while and see what happens. It is interesting that it does not chew bottom rib flipped. Maybe I installed it wrong again.
Anyhow, spindle runs fine. I am happy to have a working router spindle. Updated the document in the files section. Just added couple of pics of assembled spindle, so no need to recheck it.
Thanks again to all the help from FOG members.

Well same thing happened with the new belt which was a D&D belt I bought online. I am no longer sure if the first belt was damaged due to bad install. The belt is tight but the flex seems comparable to the std. shaper spindle. Here are 2 short videos showing how much belt flexes under ~equal pressure. Should I reduce tension on the belts. I will also call felder tomorrow. How can I determine if there is miss alignment between spindle and motor pulley? As I write this, maybe a measurement comparison of the shaper spindle with router spindle can give me an idea. BTW, the damaged 8 rib belts appear to run okay if I position the missing rib on top. Not sure, what would be wrong if I just use these belts. Imran
