 More of a cleanup than a rebuild. It's been used with water after reading several threads on here I think I'll convert it to oil. I'm also going to make a new vise and get the weight driven auto feed going. My issue now is I need to remove the arbor so that I can sandblast the inside of the oil reservoir. There is a roll pin on the inside shaft that I need to remove. Then I can remove the split ring on the outside and slide the whole shaft and bearing out. I banged on the pin a little bit and it seems pretty stuck. I'm soaking it overnight with dark thread cutting oil. That's absolutely the best penetrating oil I found for breaking loose rusty joints. I'm going to bang on it a little more in the morning but I'm not holding out much hope. I don't want to beat on it too much as I'm afraid of messing something up. Anybody have any good tricks for removing these pins?  |

W/O a bigger pic. showing the space better, it looks like the shaft might come out toward the inside instead of going to the outside. Likely a snap ring under the gunk, same as on the outside.

 You can't see much more of these pictures, but I can't see much more looking at the actual thing! I actually got the roll pin out pretty easily after soaking it overnight. The piece that the roll pin was through seems to be stuck on the shaft. And even after I removed the split ring the shaft will not move either direction. What I thought was grease packed into the bearing is some sort of fabric washer type thing that I assume holds a lubricant. The whole thing had a piece of rubber hose and hose clamp around it originally to keep coolant out. Does anybody know exactly what this fabric that was packed in theirs for? I guess my best option is to dig that stuff out clean everything out and see if there's a ring on the inside. I'm just a little concerned that once I rip that stuff out of there that I still won't be able to get it apart and I won't be able to put it back together properly. Anyone work on one like this before? Any advice before I screw something up? Also wondering about the possibility of this having been pressed into place. |

There just about has to be a split ring on the inside since the shaft won't move either directions.

I'm guessing that was a felt washer to keep stuff from hitting the bearing. Seems like waterpump bearings were popular to use on smaller trim saws, lots of those are press fit. Did you remove the SNAP ring already? It could press in/out either direction like Larry said, (wo seeing the bigger picture.) Might be the shaft has to be pressed into the bearings and they will come out of the saw together. See if you can read the numbers/manufacturer on the seal (england 1591?) might get a hint if you can find that bearing.
Were they noisy? seems like a lot of work just for a clean up? 2c.

Not noisy at all. It runs smooth. I just thought I'd get too much crap in it trying to clean and coat the tank. I was thinking I had gone too far already but maybe it's not too late to try to clean things up with it in place. I haven't removed the inside snap ring. I haven't even seen it yet. It would be very difficult to get to. I don't think I can get snap ring pliers on it unless I got the flange with the roll pin off the shaft. I can't get the straight attachment for the pliers in there and I don't think the tips on the 90 degree head will reach the ring. I appreciate the 2c and any other comments or advice!
