- Cement Mixer Restoration Disassembly P3. I restore a cement / concrete mixer from the late 50's/early 60's. This part of the restoration is about the detailed disassembly, the drive rotational parts, gears, shafts and pullies.

The mixer was picked up by my father in the early 60's. The cement / concrete mixer has seen a lot of work and abuse from many members of the family. It is time to get it running again. I will start with the GE Electric Motor then move on to Jack shaft, Brake, Yoke, Drum.
Lots of work to do.

My favourite workbench is the outside one like yours. Lots of light and fresh air
Lot my outside shop. But needs a serious repbuild, maybe this winter if the weather is not to bad. Thanks Mr E.
0:46 That unspoken but wonderful moment when you're cranking on something with a fully extended arm and you _don't_ split your knuckles when it breaks loose.
Oh yes always a good thing. Thanks Atlas.
Well that sure is a big capacity Randy, larger then anything we have used, the mixing drum sure shows a lot of mixing history, was expecting planetary gears in there now see some bearings we love bearings. 9:00 minute in we love that shaft system, lots of great work parts making to do in there if you want to.
Lance & Patrick.
Well these bearing are well broke in. And will be going right back in. Going well just in a rush to get clean and a coat of primer on before winter. Thanks Patrick and Lance.
For as little maintenence that cement mixers seem to get, that old girl does not seem to be in terrible shape. I will be interested to see how you deal with the yoke journals & caps. Nice work on the motor BTW came out well. Cheers
Thanks Warren, so will I.
Nicely done. Glad to see you took the time to save the tags. I wish they still made those out of metal.
Thank you Grip. These are pretty nice etched Brass.
Great progress , i bought some of those brake drums home years ago to make a pot belly stove but the wife stole them for her pot plants ! Cheers .
Thanks Max. My son gave me this one to make a vise stand, nice and heavy.
I've been enjoying this series. You do a very nice job showing how to work on old stuff without destroying it. I was going to suggest that you set up an electrolysis tank for those greasy nasty parts. The lye water saponifies the grease and oils and does a superb job of eating the grease and paint away as it bubbles. And it treats the rust too. You can get a 50 lb bag of CaOH at a pool chemical place for cheap. Anyway, look forward to seeing it all back together.
That would of been a big vat. I am pretty much done with the cleaning phase. The grease what not to bad to remove nice and hard just chipped right off. Thanks for the suggestion.
@@RRINTHESHOP I was just thinking of the smaller bearings and jack shaft bits. Not the bigger stuff. I like using lye instead of solvents for greasy stuff because it essentially just turns it to soap. Much easier to dispose of
Enjoyed...you need a road trip to Ray’s glass beader..LOL!!!
That would of been nice. The hard grease actually chipped off pretty ease then evaporust and wire wheel they came out great. Thanks Chuck.
Surprising how most disassembly;y went pretty easy - if messy! Lots of scope for clean up and restoration.
ID plates were probably the most resistant items... tho lay shaft was quite a mess!
Clean up almost done, lots for work but going well. Thanks Chris.
Looking Good Randy.
Thanks Old Iron.
great job getting those tags off , They can be a bear .. ENJOYED !!
Yep, Now I have to get the steel screws out, fun. Thanks Shawn.
That is a tough cleaning job for sure. You need Mr. Clean to come for the weekend. Of cxourse it will look like a new one when you get done.
Not quite done cleaning yet but getting there. I don't know about new but I am shooting for usable and nice. Thanks Harold.
Hi Randy... All that old grease worked like cosmoline to hermetically seal the parts! I suspect there is a lot of hours on that little hammer, the length and weight look spot on. Really enjoying this series! 😃👍
Yes it did. Actually it chipped off quite easily with a sharp knife. Then everything soaked in Evaporust the wire wheeled, cleaned up great. I made that hammer on a ship one day, had it a long time maybe 30 yrs, that is the large brass hammer. The small brass hammer was from a close friend I lost to cancer, I use it all the time great for center punching. Thanks Scout.
@@RRINTHESHOP I love tools with a story!
@@ScoutCrafter Thanks John. Same here.
A lot of work but it'll be worth it.
Lots and lots. But progressing right along. Thanks Rosa.
Interesting cleanup there Randy! I never thought much about it, but I'm a little surprised by the number of individual parts to clean up and refurbish. But every one of them has an obvious purpose, which is always good. :-)
Lots for clean up, Big parts. Start repairs soon. Thanks I Wilton.
You really know how to mix it up ;)
No mixing yet. Working hard at it before the winter comes. Thanks Don.
Never seen pillow block bearings like that before.
These are quite old. Thanks Ken.
Grate video series.
Thanks Doug.
Looks like you need to make a road trip out to Brian Blocks place. :)
Yep that would be nice. But for the cost I could just buy a new machine. Thanks Tom.
I was about to say the same thing.
@@metalworksmachineshop It is a bit far for me.
Will you use Evaporust? Electrolysis? Something else?
BTW, there is a way you could bore that on your lathe. Like Keith Fenner does for bushings for shafting occasionally. He fixtures the part over the compound, runs a shaft on the lathe with a toolbit in it and bores out the casting and/or sleeves it. I'm sure you've seen him do that. Albeit, you would need some odd fixture to hold the casting, but you only need to keep it stable and on the center line so you can bore. The casting looks offset enough that it might give you enough room to get it on center line...🤔
Thought about it, still thinking on it.
Morning Randy! Looking good,
Morning Craig. Is the coffee hot? Thanks.
Randy Richard In The Shop : Yep, the wife knows how I like it.
@@CraigLYoung I make the coffee every morning for the wife.
Randy Richard In The Shop : So do I on Saturdays and Sundays. My wife gets up and makes coffee for work and when I get home.
@@CraigLYoung What a good women.
Crusty is for sure the state of that shaft, it will look good once you peel the rind off it.
Was not to bad John, chipped right off, the evaporust and wire wheel, looks new. Thanks John.
hey Randy, on the journals of the drum cradle: there seems to be what looks like a hole for a drift pin. maybe stick a drift pin punch in there and give a few whacks and see if something moves. my guess would be that those journals are probably a press fit stub into the yoke assembly
I will look at that. If I could remove them it would be grand. You may have just made my day. Thanks Mike.
@@RRINTHESHOP it could also be a grub screw. so it might be a good idea to clean that hole out good to see what's in there. hard to say at this point.
in the worst case a guy could zip those journals off with a grinder and redo them with a press fit stub
Well the holes are grease fitting holes. And they look to be part of the casting after close inspection.
I will look at the cutting off Idea. Thanks Mike.
Given your tooling I think I would mount that thing sideways on your mill table lay the head over 90deg and swing the boring bar around those journals in reverse to get them trued up. That is how I worked big swing parts on the Cincinnati before I got the G&L.
I am looking at that. I don't think my table is long enough and the yoke is big and heavy. Thanks Brian.
@@RRINTHESHOP I have in the past used a rolling cart and wood blocks to shim and support items too big for the table. :-) It would make a great get er done video! lol
@@bcbloc02 Cart is good idea, I have that. I need to get the large ring gear off, It is keyed, set screw, & cast Iron. Maybe a little heat and it might come off easy. Any ideas?
Randy Richard In The Shop send me some good pics of it in an email so I can get a good look at it
I kind of thought as you were taking it all apart that the thin sleeve over the key was what had been keeping the preload on those tapered bearings... (and apparently not too well, at that). Maybe that is not an original part but a makeshift replacement for the real keeper... and maybe a more effective one could be made from stouter stock. Best analysis I can do from 1800 - 2000 miles away!
Yep I think it was a retrofit to fit the v-belt pulley. I think it was chain drive before. So it needs a redesign
so the end play can be adjusted. Good job on the long distance analysis. Thanks Wes.
Messy but fun -jim
Well I have made it through the messy part and on to repairs. Thanks Jim.
Bring me the bigger hammer!
Where do I deliver it. Thanks Youchol.
I don’t claim to know what I’m talking about, but couldn’t the drum arms be out of round intentionally to cause the drum to return to a neutral position so that it remains in place while spinning or bringing back up after tipping?
Good point Daniel. I did look at that or was it worn from sitting and being hauled around in the drum down position. I really have not come up with a good reason as of yet. I will look a this some more. Thanks for the great comment Daniel.
Better old, dried grease than rust...
Yes the hard grease actually chipped off pretty easy. The paint is being the most work. Thanks Joe.
I guess I must have missed the reason for this restoration. Are you planning to do a huge masonry project when this is finished.
Well I want to make some new steps and rebuild our deck. The motor just hummed. So why not the whole thing needs work. Been int he family for a long time, see description. Thanks Jim.
@@RRINTHESHOP Thanks Randy sorry I missed your original explanation. Looking forward to the next episode of this project.
@@jimpritz4169 Not a problem Jim. Thanks for watching. It is coming along.
Keeping it interesting. Please don't hammer on that drum again when the mic is on. LOL Getting 'er done.
Thanks Vernon.
A mixture of crust and hardened grease.... Beuark...!!! Not the most interesting part of a restoration fro sure...
Just like Harold says, "Keep on keeping on...) 😎👍
Yep to far into this now KOKO. Thanks Pierre.
Looks crusty, it appears to be a big machining project
I am still cleaning. I hope to get to repair stage soon. Thanks Jim.
