A viewer below pointed out that your snap ring was an internal, not an external. So I went back and looked, and sure enough he was right, it's not even round on the inside. Make sure you replace that when you get a chance, you did an excellent job, wouldn't want to see all the gears get messed up becuase thats not going to hold.
8:57 That gear looks to have been pulled out losing it's snap ring and THEN the R8 was HAMMERED back in with the key misaligned so the gear hub sheared off the top of the key part way down. You didn't mention how you dealt with that. New key? repair of the keyway in the gear hub? You are lucky that thing still works because it was used by a real ape.
hi nice resto video - well done just one thought/comment - the dislocated snap ring - the shape of it looks like a snap ring for bores, not for shafts; are you sure it was not mistakenly installed by the guy before you and slipped off the shaft due to being the wrong one ? snap rings for shafts have the ears facing to the outside, not the inside ... what do you think ?
By chance did you happen to measure the spacers that offset the bearings? I've got the same type of angle head, but found out both spacers were missing. The one on the input shaft I think I can deduce the thickness for it, but the one on the output shaft, I would need to find out what thickness it is for proper meshing with the gears.
A slide hammer would be a better tool for removing the internal R8 shaft rather than hammering the casting off of it. OTC part 8003 is an adapter between 5/8-18 slide hammer threads and the 7/16-20 R8 threads.
I was only able to find one of the 3 bearings on ebay for I think 40 or 50 dollars. I didn't get around to checking with my local bearing supplier to see what all 3 would cost. I'm just glad I was able to save these.
What are the bearing number please? all 3. I am trying to design one and would like to use the same bearings as is in the OEM attachment. Thank you. I cant find them on the internet anywhere.
you can see the bearing no.# on the bearings themselves, Mine were (1) 1207 FF and (2) 6008 2RS, if this helps? I'm having problems with the spacers that hold the bearings in proper place for gear meshing, would you have the spacer dimensions? Actually I just need the thicknesses of them, I can figure out the rest.
I don't have a right angle machine to measure the parts. I am trying to make one and so thought it would be a good idea to use the same bearings as are in the original or knockoff ones. Sorry about that. But thank you for the bearing numbers.
FYI, I researched price through a major bearing supply company in Canada and was looking at a price of $1009.67 CDN per bearing, I almost fell over. They were special order.
My guess would be someone loosened the housing clamp bolts before removing the machine drawbar. When the housing didn't move (evan though there is a bolt between the 2 clamp bolts to open the gap) the person gave the housing a wack , then realised they forgot the machine drawbar.
What happens is people tighten the collar then the drawbar and it pulls hard on the shaft and causes that snap ring to come off. That's why they put the tag on it to tighten the drawbar then tighten the collar
A mi me gusto mucho el video en general , y mas la seccion de momtaje; tu tecnica con la edicion muy buena, y me diverti mucho; Gracias!

Thanks for making this video! Can I ask where you got the mount at to hold your dremel to the tool post?
Its a 3d printed mount, I think I got the file off thingaverse
hi
nice resto video - well done
just one thought/comment - the dislocated snap ring - the shape of it looks like a snap ring for bores, not for shafts; are you sure it was not mistakenly installed by the guy before you and slipped off the shaft due to being the wrong one ? snap rings for shafts have the ears facing to the outside, not the inside ...
what do you think ?
That was not even round on the inside, look at that again, it almost certainly is the wrong type.
By chance did you happen to measure the spacers that offset the bearings? I've got the same type of angle head, but found out both spacers were missing. The one on the input shaft I think I can deduce the thickness for it, but the one on the output shaft, I would need to find out what thickness it is for proper meshing with the gears.
I don't get the measurements, sorry
Excellent job, that grease had done it's job for way to long.
Where did you get the replacement keyway for the R-8 collet?
Great job.
A slide hammer would be a better tool for removing the internal R8 shaft rather than hammering the casting off of it. OTC part 8003 is an adapter between 5/8-18 slide hammer threads and the 7/16-20 R8 threads.
Nice job on the fix. Did you check on replacement bearings? I know they can sometimes be pretty expensive for essentially what is a spindle.
I was only able to find one of the 3 bearings on ebay for I think 40 or 50 dollars. I didn't get around to checking with my local bearing supplier to see what all 3 would cost. I'm just glad I was able to save these.
Could I ask what oil you filled the unit with and how much? Thanks
I just used bearing grease

I don't have them documented. If I pull it apart again I will note them and let you know

Any idea how much of an interference (press fit) there was between bearings and housing? Did you happen to measure when it was disassembled?
-Ben
I don't know the exact measurements, it was fairly tight though.
My guess would be someone loosened the housing clamp bolts before removing the machine drawbar.
When the housing didn't move (evan though there is a bolt between the 2 clamp bolts to open the gap) the person gave the housing a wack , then realised they forgot the machine drawbar.
