New Haven Metal Planer Restoration - Part 14: Disassembling a Gear Reduction Countershaft

[Music] hello Keith Rutger mini-14 org guys today we're back working on the metal planer restoration and next onto my next drive shaft that's up underneath the bottom of the frame of the machine and basically this is what gears down the the spinning motion from the the flat belt pulleys to drive it slows it down to drive the big bull gear and we got a couple of gear reducing gears here so this is the gear that drives the bull gear this one is taking power off of another one and we've also got this whole mechanism down here on the other side which we'll be going into a bit more this basically adjust how much of a feed over the cutter moves each each stroke of the machine so there's some fairly complicated mechanism I say it's complicated I haven't been into it yet but we're gonna get in there and look at it at make sure everything's good so job for the day is get this taken apart get things cleaned up start giving you things painted I don't know if I'm gonna have to do any repair work or anything on this whole mechanism until we get in there we'll play it as we go so let's get going I start by taking the bearing off here I was just looking at these make sure they go back on the same same way and so forth so I'm think I'm gonna put a couple of witness marks on here so that I make sure that everything matches up let me grab a punch so I'm just going to put a matching punch there one mark one mark the other side over here I put two marks on this one and I'm also going to put a single dimple down here on the ends just so I know that the one goes on this side and that'll pretty much only place Evelyn can go be there so the bearings they feel pretty good we'll know better once we get into these but go ahead and pull these bearing caps off [Music] that bearing looks good thing look I don't think we're gonna have to do anything to those so and just put these back together like such so I know what goes with what go ahead and take this one off same thing and that baron looks like well there's a little bit of scoring in this one that one may have to get report we'll we'll evaluate that later on but once they get it cleaned up but that doesn't look all that great all right so this bolts up under the bottom of the frame there's a hand wheel here that is froze up but that adjusts on this worm gear and that is just a dog this is just a trip dog that basically adjusts how much this thing ratchets each time and that is directly proportional to the amount of movement in the cutter as it's uh going the machine so I don't see any bolts taking that on that's just free spinning on the shaft so let's work on this in see what we got to do here now I got this big nut on the end and I had to take a little break here and go round up something to take that out that's two and three-quarter inches across my biggest suggestible wrench fell way short but made a couple of phone calls I got a friend that had a two and three-quarter inch socket it's one inch drive but had a do search of 3/4 inch drive so see if we can get this apart I may have to go put it as a big vise to hold it yeah all right let me move this to a new place and we'll try that I took this over to my vice it was gonna be kind of hard to get the camera set up in there it was just such a tight fit with the gantry crane that I just broke it loose and then brought it back over here to the table and there we go no problem at all looks like there's a key way in here holding that on take my lead hammer it's got it comes out all right let me block this thing up and we'll get a brass drift and drive that on out I've got a brass punch on here now and we'll just continue driving that on out the brass just protects doesn't mushroom that shaft or anything like that the brass is softer than the steel [Music] there it comes move this out of the way right now I believe this whole assembly just comes right off I've been sitting here looking at this shaft and you can definitely tell where it's worn from running in those bearings and where's just turning in there it looks like it's between 10 and 15 thousandths undersized depending on where you're at we've got some pretty nasty and it's not terrible but it's it's pretty bad still right in here some scoring on the shaft and I'm sitting here just trying to decide what I want to do on this shaft I got a couple options option number one is I just make a new shaft and honestly that's where I'm kind of leaning towards but option number two is I've got a spray welding rig over there where I could build this up basically turn it down a little bit spray weld on here build it back up I'm gonna have to think about that price some material - let's see this this is a inch and an eighth roughly right here that the gears are on and then it turns down to inch and excuse me to an eighth and then this comes down to inch and 3/4 and then this comes down to about an inch and 5/8 down here but I'm thinking probably just gonna make a new shaft right now so I need to get my gears off we got a couple of keys in here that are wedged in place I've already gettin measured where they are so I can make sure that I get them back in the same spot when I put it back together so let me get a hammer and a punch see if I can knock those keys out that's gonna be tough oh that's good swatting in there to that so that's just a tapered key wedges in there let's see if we can get lucky on this other side - there we go all right what nearly as bad as I thought it was going to be and now I'd say it's over the arbor press to see if I can press these press these off before I do I'm going to get in there just clean these shafts up real good and make sure there's nothing on there for it to catch home I've got the gears removed now off of the shaft and guys I took this out to the museum to use the big press out there this big gear or a small gear here it was a little bit too large to fit through the gap in my arbor press that I have here in the shop so I went out using the hydraulic press out of the museum and I took a little quick video of it while I was out there the big year actually both the gears came out very easily I put the big year on first and it just took a couple of pumps and the shaft just literally fell out I flipped it over put the small gear on there and I didn't have to press it I was just able to I'm really almost the weight of the shaft was enough to pull it out I had to persuade it just a little bit by hand that came out without having to press at all so these are off now and now that I've got my shaft completely out I I pretty much decided I think I'm just going to make a new shaft there's just some stuff in here I'm just not crazy about and the biggest thing is right here there's some pitting in here I mean that's that's an eighth inch deep in places and yeah I could probably spray weld it and be okay but I'm gonna feel better just replacing the shaft I think so I get some material ordered and that'll be a job we do on the lathe probably turning between centers and get that done so anyway we're done with this part let's get over now and work on the other two pieces that we still need to get completely apart all right so this again is just basically what indexes the the feed the cross feed or whatever there's some little dog places in here and by adjusting the crank on the piece behind that you can adjust how far it moves on each stroke there's a also some adjustment and there's a little piece that goes across here that depending on where you put it out it adjusts the whole stroke so this piece just kind of I think pivots back and forth I want to take it apart though I'm not sure what's on the inside that there well let's just take it apart and see I think I know but let's let's take it apart go ahead and take this a little oil cup or grease cup rather it's missing the top should have a little thing that you turn and it pushes grease down in there let me get that out yeah so this is just a it's got a little friction clutch disc in here feels like a leather maybe I'm not sure what that is we'll figure it out and it's full of grease we will have to get all that cleaned out yeah there's another friction piece behind it and looks like we got bronze bushings on either side and those are fairly scored up I'll probably just end up turning new and press those out and replace those okay I'm just gonna for right now we'll just kind of put this back together that's gonna take a good cleaning so this piece here is a worm gear worm and a worm gear and basically what this does is adjust this little dog this is a stop and that little clutch piece we took apart in a minute has a piece on the back when it comes around that kind of stops it from going past a certain point and it is really really really tight so basically this whole piece is turning inside of a sleeve over here and I think what I'm going to do is turn it so that the worm is not engaging the gear and then hopefully I can get all of it taken apart now I think we can turn it now okay so now this should just come off yeah I think what we're going to have to do here is there's a pin holding this handle in place should just be a tapered pin see if I can knock that out this looks like the small side bigger draw a pin okay now this out your PIN holding this in place or does it just screw off yeah there is a drop pin in there huh that's unusual that pin doesn't go all the way through there's a little key way cut in there that pin fits on let me see if I can get some vice grips or something and pull that out yeah came right out no problem now that comes out all right we can get all this stuff cleaned up there we go there's the sum of all the parts everything is taken completely apart and next step is to get all of this cleaned up go spend some quality time over there at the parts washer getting all this grease and gunk off of it parts are going to be repainted and we're gonna have to make a new shaft and then of course reassemble everything so that's kind of the game plan going forward on this I won't bore you guys with the cleaning up and the painting part but we will bring you in there and let's just see us making that new shaft I got to get some material ordered I don't have a material on hand to make that out of so I have to get that ordered you know but that should be it shouldn't be too terribly bad of a job a little bit of lathe work and then the millwork for a couple of key ways and we should have that knocked out easy enough and be able to get the next shaft countershaft back up underneath the bottom of the the plainer metal planer and with that that'll be a wrap guys as always thanks for watching the videos please subscribe the channel if you haven't already comments are appreciated and leave me a thumbs up if you like what you see and we'll catch you on the next video I'm gonna get this planer knocked out one more bite out of the elephant gonna take her one bite at a time thanks [Music] you
