Repairing New Holland baler snapped crankshafts. Part 1

In this video I start the job of repairing 2 baler crankshafts that have snapped.
Firstly I start by cutting 2 lengths of 75mm bright round bar to use to make new journals. These are then turned down to size in the lathe with a bigger radius to hopefully improve on the original weak point. The shafts are then parceled up and sent off to be hardened and tempered to match the manufactures specifications.
Next up was to start making the Jig that will be used to hold the 2 halves of the crankshaft inline while the new journal is welded in. I cut some 80x80x6 box section to use as the main frame then flame cut some rectangles from 40mm plate to use as the clamps.
The 3 top halves are drilled with 4x 12mm bolt holes and the bottoms are drilled and tapped to M12 to match the top. They’re then bolted together and a 40mm hole is drilled and reamed in the side which will be the starting hole for aligning to weld onto the frame and also to line bore.
The frame is then welded together and the crank is temporarily placed in and clamped down to see where the middle clamp will need to go.
After some over thinking its decided the third clamp can be on the same centre height as the 2 ends. Some more box section is cut and tacked on then then fully welded around.
That’s all for part 1.
Hope you enjoyed the video. Thanks for watching.

I look forward to Sunday morning watching you solve and repair old machinery to help them live on for a little bit longer instead of being sent to the scrapyard to be turned into baked bean cans. without people like you farmers and other small businesses would have to buy new machinery that is not cheap you are helping them stay in business that’s why this country needs people like you. thank you.

I am a machinist and your doing a pretty good impersonation 🤠 I learnt (at machinist school) that shafts with a hole down the middle are actually harder to shear off than solid shafts. If word gets around the other farmers that you can fix these things you may want to consider putting a hole down the middle. The size of the hole doesn’t matter that much as the shear originates from the centre so you remove the starting point. Spiral and Gun taps are better for machine use. You are right to start the straight fluted taps in the machine then wind them through by hand snapping off the chips as you go. Spiral taps the chips come out the top of the hole and gun taps the chips are pushed ahead of the tap so not a lot of good in a blind hole. Generally gun and spiral are called machine taps.

Another thought might be to have them case hardened rather than through hardened and tempered, Another thought, from a complete amateur, might be how is the welding going to effect the hardening, might it actually cause a brittleness in the pin. Another another thought is the design flawed with odd web support causing a bending leading to a fracture.

The best high performance crankshafts are hollow journaled. Doug Kidde, now Arrow precision make and sell these from about £5000 but I don’t think they have bailers listed in their products Arrow one of those quality British engineers, at the heart of a huge industry of motorsport. Like snowball, he started in a shed.

@DavoShed 18 күн бұрын

@@tomtdGreat example. I didn’t know they did that. It would be good to have a close look at the end of the sheared pin to see the pattern. I was thinking of a drive shaft as an example. They are always hollow and it’s not just to reduce the wait. Perhaps Mr Snowball will put a drill through 🤠

I'm too far from him, but this has indeed made a solution for peeps around my brother's farm that operate NH units. Some of them have taken to buy other units to scavenge for parts. Kinda douchey of NH to do this to be honest. They should've owned up to their mistake, this isn't just "wear and tear" this was bad design from the get-go. Nobody in their right mind would expect this to last. NH either screwed the pooch or did this on purpose.

If you have any letter stamps it's a good idea to stamp the ends of all bar stock whenever you receive it. Then re-identify it with its grade as you cut a length off the bar. It takes a few minutes, but the next time you need a specific grade of steel it will be much easier to identify.

Yes, the farmers need a good and economical fix for their machines. At the same time, you need to receive enough compensation to pay for the new toys and make a decent living. Both we and the farmers would not be well served if you end up going belly up. Don't undervalue your work.

Safety flipflops, a coat hanger wire electrode , and you have a repair that looks just like a real repair . Coat of paint, and send it out. In a time before cutting inserts, we spent an entire semester grinding cutting tools, good to know how to do it. The biggest thing I notice precision machinists ALWAYS do is faceoff everything they are going to turn. Regardless of what it is, or is going to be, when a piece of work gets setup in the lathe, it gets faced off.

I think that baler crank is actually called a ”stuffer” . It feeds hay or straw or silage into a chamber and after several packs or slices are gathered up to predetermined pressure the big ram pushes it out into the bale chamber. But don’t quote me on that 😊.

You certainly get some unusual jobs in and this isn't the first time you've had two of the same job come in for the same repair. It seems to be a problem with parts no longer being available for older equipment, so it often means replacing the equipment if parts can't be made or repaired. But as usual, Snowball Engineering to the rescue to save yet another old machine from the scrap heap and get it back in action again.

From my vantage point, some 3000 miles away mind you, it appears like a lack of a proper radius is what might have caused the failures in the first place. For the tapping head Tommy Bar, May I suggest that you make a post that goes into a T slot and sticks up high enough to suite you. that way it can be positioned anywhere. Or even something that bolts to the back of the vise if there are some tapped holed back there to move the jaw to the outside. I like the fixture idea. I will be interested in your thoughts on S-Power and it's build quality. I hear they are inexpensive as far as boring machines go.

@cleggy65 15 күн бұрын

Hey there! Great videos by the way, however, I couldn't help but notice your welding process of using solid wire MIG/MAG for most of your projects. It's great for structural and farm repairs (and cost)! However, for high-quality materials like the round bar in your video, consider switching to a flux-cored or MMAW filler wire/rod and a full penetration weld prep. This could help reduce imperfections in the weld that might lead to failure down the line. Just a thought-I suspect the original failure might have been due to a weld defect like porosity or lack of fusion migrating into the parent material. Hope this helps!

@bobhudson6659 19 күн бұрын

Look for and research what a gun tap is. That sort of tap has a slanted cutting edge on the lower leading edge. The slanted edge forces the material coming off as you are threading it down the hole instead of being caught up in the hole being threaded - but has to be a through hole to allow all the cut material out the bottom of the hole. Although at the same time, if you are careful and pull the tap out a few times on a blind hole, you can blow out the cut material on each retraction. The safest way when you are threading a blind hole is use a spiral machine tap (again research it). With that style of tap the material being cut spirals out back towards the operator. But buy good quality taps. Guhring make excellent taps although they are not cheap. In Australia a Guhring M12 gun tap can set you back $120 - $140 (each). But look after them and use plenty of good quality cutting lube and you'll be right. Look at some KZfaq videos on how to use each style of tap. Retired machinist/mechanic in Land Down Under. Late note. Re reaming textbook says (and backed up by machinists who are a lot more experienced than me), reamers run at half the speed of the same size drill but at twice the down feed. Next note. Run milling cutters in a collet - ER40 collets and holders are great. Using milling cutters in drill chucks is to ask for trouble sooner or later.
