PULL GEAR Disassembly Tips #471 pt 2 tubalcain

hello again it's mr. peek - - - also known as tubal-cain welcome back to the shop and this is tips number 471 as the second part of a disassembly and rebuilding the pull gear speed reducer here now hopefully you've watched the first part which was tips for 70 and this is a continuation and I'm not sure just exactly how many more videos that will be in this series depending on how fast I work or should I say how slowly I work well in the last part the first part I separated this you saw me do that and then I also believe it was off-camera removed this bad bearing I just simply drove it out from the side which was simple enough I still haven't cleaned things up but this bearing is is bad it's just rougher than a cob so that has to be replaced along with two others and I'll use sealed bearings many of you if not all of you have watched my two pleas for help and those are temporary videos people are asking me not to take them off I haven't decided yet but there were an awful lot of responses on the first one like 16,000 people watched it and hundreds of comments many of them are repetitious of one another go through and read those if you're if you like that it's pretty interesting really and I think it was a challenge to many people to help me and I appreciate it very much but now I'm forging ahead and the next thing I'm gonna do is to clean these up of course with thinner but I'll do that off-camera but looking here you can see the planetary gears the reason there's two pairs is that it reverses the rotation so you don't have to run the motor in Reverse I've said that before so the next thing I want to do is to remove this and I had some good suggestions on that so here's how I think I'll approach it the whole idea now is I want to remove this bar but the pin here has been pinned over so people suggested cutting it all writing it off peeling it down to submission so it this will come off and I think I'm just going to file around this so this will pull off and I may very well redesign this when I put it together because someone showed me a picture of one that either had been modified or they changed the design from the factory and in fact made the rod threaded it might have been a larger diameter rod as well and it had a little neural not on there kind of like what you would see on the battery post years ago a small you know six or dry cells like kind of dry cell so it could easily be either adjusted for attention or to disassemble and I don't know the purpose or anything about it other than people sent me a lot of pictures and so appreciative of that but after I get this off that's when I intend to press from this side and see if I can get it apart I only have a small mechanical dick brand arbor press number zero which is only one and a half ton I doubt that it's got the pressure but I'll probably will heat this up anyway but what I'll do now off-camera is just to take a little needle file and file that the head off of this so that this will pull off that's all I'm gonna do it even if I remove a little bit or wood snip it off there might be enough left there to Desalle imagine but that's something they'll worry about later on as I reassemble it you know what that only took 60 seconds of filing I believe it's just gonna come off now and you know that needs to either be reworked or just cleaned up or something but it's rougher than a cop know before I get back to this let me just say that on this you know that Bobo got a hold of this we talked about that before and Bobo is a rough worker but you know he broke this and Jim Bollinger I just got an email this morning from Jim Bulger he said you want me to TIG weld that for you and then he's of course you'll have to machine it well at this time and I think of Jim and I'm talking about Jim of do-right machining you know what a great guy he is he's a big man and you see what a wonderful father is a boy if only we had more fathers like that in this country that spent time and effort with their boys you know we'd have a lot less crime I tell you but and thank you for that Jim at this time I'm not gonna do it you know I just like to get things like this done and at my age I can't Terry so that won't get welded yet at this time now the question here is when I release the vise grip pliers is that going to disappear to where I can't even grab it anymore I think they'll still be a little bit left sticking up wrong she came flying out of this end all right I didn't know that that it would come on I was thinking that was a blind hole even though I looked at the drawing now remember and I'll put the drawing again in this video that's a patent drawing a patent drawing as many people have pointed out is not a working drawing was a concept drawing it is not a dimension drawing many eye parts of it were changed in any patent not just this one so we can't totally go by that but but that's all there is to that little plunger it's a fairly strong spring all right we'll set that aside looking at this now what I'm going to try to do now is to press it out from this side I don't do a lot of press work but this is the time every two years when I need a hydraulic press but I they're cheap enough at Harbor Freight horror Freight where I could get one but they're just in the way that that's the problem it's just in the way 99% of the time I just turned this down in the lathe so it would fit here and I know what's not long enough I got another piece standing side by side but I just want to see if it's a goal or no goal and the question here is am I going to just press out the steel part or the brass part the brass bushing and the other question is should I attempt to press and out of this bearing in other words just support it with a ring around this bearing and something like this like my fingers and push or should I support it clearer around the edge here in a manner using this flask this is one of my phone reflashed just happens to be about the right size to press but this is a most awkward piece to set in my little press so I'm still playing around or should I forget the press all together and use one of my bigger pullers that's that's setting on this right now so I got to shore it up a little bit or should I use one of my big pullers and push right here with a polar so I may have to back up and use a polar rather than the press because you know I got one that's pretty darn big and but I prefer a fine thread on it I believe that one has a coarse thread so anyway I'll go out to the press now that's out in the garage and just give this a little yank and see what happens I'm not expecting anything to happen and then the second thing is I'm going to put this in the oven and doggone you know my wife she really annoys me she's got a casserole in there but at least she's preheated it for me alright I'm out in the garage I'm a little ashamed of this rednecks setup here but it since the table that I have this little press on is so wimpy I've got the whole thing chained down to the front axle of my Moline tractor so and I got a cheater bar and I'm ready to press I have very little faith the press has clamped onto that table the drawer has to be open to for clearance for the clamps and notice that I have a jack under there to level about so let's see what happened I don't expect much even with the cheater bar notice also I'm pressing on the steel shaft not the brass bushing cheer bar no confidence nope she's not budging just as I suspected now step two I'm going to put it in the oven and heat it up to 350 so I'll be back in 30 minutes try it again and I still only have 10 percent more confidence and that method but we'll give her a try I need a bigger press with what I need one hour later and it may not look any different but it's 400 degrees see what happens she's given I may be bottom doubt and I'll so I'll have to take a look I'm glad to get it apart I just hope I can remember the right order of putting it back together but the whole look a little bit scuffed up these are good cleaning so I'll get that all cleaned up with solvent I probably should have marked the gears but I did not so let's put together the same way now this is still warm but I have to get those two bearings off so I'll use a pore on those and both of them are really rough just terrible well all three of all three bearings are bad just no doubt about it someone suggested just read lubricating but now you know that's not right when it bearings that rough and needs replacement and bearings this is probably about 50 or 60 bucks worth of bearing I would suppose but I want to get them sealed all the gears look good I hope that the know I do see some marks on these gears and this here hope it's alright next using a pore I'm going to try to get this small bearing off the shelf it's coming off but it isn't easy and more did it make a snapping sound when it first let loose looks like it has to get pulled all the way I thought there would be some relief it appears to be a 17 millimeter all right I got that one off and boy it is nasty now for this one and I'm just going to have to assume that it pulls off right over the gear I think all of you watching know that most all bearings are metric in other words this one that I just took off is a 40 millimeter OD and if you wanted to check this it's 12 millimeters and the inside diameter here is 17 millimeter therefore the shaft is you might call it an odd size but it's not out at all and also this 17 millimeters well why am I telling you that because we know that this has a metric bore I haven't looked up the size and everything but the outside of this gear is basically 25 millimeters so I'm assuming that the ID of the bearing is 25 millimeters and will come off well I know it can't come off in this direction because this shaft here Hollow and all is all one piece so I'm going to pull from this way the same as I did on the previous bird you're savvy well the other port doesn't have the capacity so we'll put the heavy duty window to work here I like this one I don't see a brand on it but they could you pull out the pin which has a little ball there and move it up to whatever length you want or whatever width you want and that quickly without fiddling around with tools or any other frustrating things you know it's set for the job at hand notice that I usually put something here so I won't bug her up the shaft that look bad enough the way it is or you I like to set it up like that all right there's a set up as you saw I had a couple things backwards I'm sure these pins around all the way and I'm ready to pull I find it easier to put this in the vise or okay can we just be done on the bench but usually have to have something in there to counteract to force us alright let's see what happens here boy that won't stay in the vise that those soft jaws it's separating you now the mystery is gone you know and this thing was together I had to plead for help and we were guessing and we were throwing out all kinds of ideas but there we got bearings three bad bearings I'll clean this up but the teeth feel a little rough I think on sharp corners but at least there's none missing and I need to clean these up just well enough that I can read the bearing numbers and there are a bearing numbers from small to medium to large all new departures 3203 305 and 3205 first thing I will do is see if I have a bearing in stock I got a whole can of bearing but that would be a longshot and then I'll get on the internet and order those bearings well in fact I did have a bearing that is the right size that corresponds with this it's a different number it's a NAPA bearing it is brand new but you know I'm not going to use it because it's just shielded and it's only shielded on one side but it is the right size but these bearings are so cheap on the internet that I'm just going to go ahead and and order them all and from what I did and I've already been on the Internet in fact I've already ordered them and they'll be here in about a week or so but they're pretty much all new numbers so I don't know if this is just an old numbering system or what but there are new numbers and they have a rubber shield on both sides and you know rubber seal I mean not a shield that is a shield sealed bearings are also permanently lubricated also they tend to retain the heat but I don't think that's going to be such a problem here so the bearings are ordered and before I conclude this video let me talk a little bit more about the parts and then the next video will be the reassembly okay now for an examination and evaluation of all the various parts and I've cleaned them up they've been through the parts washer through a solvent and you know I'm just thinking with those bearings I've got a huge box and then a coffee can folders full of bearings brand-new in boxes like I just showed you but they're never the right ones I might as well just throw them out because in the end I buy new bearings well that's just my thoughts on that so here are the four planetary gears and they are all in pretty good shape and they all are identical they do have a number on them which might be just a purse number or what it is I don't know but this company polgár probably purchased all the years I would be guessing so those are in good shape with the brass bushings in them set those aside they're all cleaned up nice I cleaned up the pins these are hardened so appeared to be just fine looking at this now cleaned up remember I have to drill and tap a new hole here later on that's no good that's where I had to remove them that was in the first video remove the set screw by drilling it out you can see there is considerable wear but not a thing I can do about that that's been ground that's ground this is just a rough turn and it didn't matter so this is good enough to reuse I have no choice anyway I don't know why I'm even saying that upon cleaning this it's even much much worse than what I thought just been beat up by my buff so badly and I just think it would be a total waste to have Jim weld these up but I am gonna have to try to dress these down because some of these corners are so that they will damage the belt and even right here look at that very rough now I as I told you I'm gonna drill no that's the other piece okay there's the access hole for that you know it's so easy to understand this all now that it's been disassembled but it was such a mystery in its original assembled form that of course is Bubba when he originally started working on this looking at this piece now I almost like to fill that with something I wish I had some maybe I'll put some jb weld or something in there and then just address that off a little bit because that's just so awful looking you think that would throw it out of balance but I'm gonna drill a new hole probably on the opposite side for that that's stem that rod that has to go in here to keep it from spinning this brass bushing looks good and here of course are the two Oilers and this hole in this hole is where the oil dripped in there these holes here are not in good shape there's a lot of galling that went on also quite a bit of electrolysis I believe that's electrolysis that took its toll unless this was a casting and there were defects in the casting so I'm not real sure but I'm going to dress this up try to get some of that galling off that's on the surface so there is where here but not a whole lot that can be done about that but this looks pretty good here and I'll clean out these holes I should knock the Oilers out but I guess there's no need I'll just blow some there and solve it maybe some brake cleaner there and get that cleaned up and i think when i reassemble i'm just gonna use a good grade of gear lube on the gears and then from time to time of course it would be lubricated through here but I don't think that's adequate unless a person was putting some kind of gear lubricant in there and I don't know what it called for and the original instructions there probably was original instructions I think somebody sent me some of that but I think to put this on the lathe and break that corner which is kind of roughing and if I would fill this maybe even take a late cut it's like they hold it true enough in the lathe oh it didn't wobble but this isn't going to be a complete restoration as some of you might take the time to do but you know I'm so busy making videos and in general I do not like restorations and I spent way way more time on that Lyall drill grinder that I intended to it that's not something I typically do but I did carry that through except for the severe beating that I took from some of you were saying that I should have changed the bearings but of course you saw me use it or you will see me use it and grind drill drills with it and it works just fine so I'm going to conclude this video this part because the disassembly is done and there'll be a delay here anyway as the bearings are are shipped and I hope they come in a timely manner so then I can start the reassembly but I'll do some of the other work that I just described here before that commas and you know this is this is just so horrible that it probably should hold this in the big three jaw with reverse draws that take a leg cut and face this just so it doesn't look too ugly but I probably would have to take off so much that that and this is the bearing that the bearing would be exposed a little bit alright thanks for watching part 2 of the pull gear project here and I'll see you in the next part it's a tubal-cain saying so long for now you
