Sorting out a worn headstock on a JCB 526-56. Part 2
HTML-код
- Опубликовано: 5 окт 2024
- In this video i carry on with the repair/line boring the front end of a JCB 526 56 loadall.
Both pin holes on the headstock needed line boring along with the tilt ram pin hole in the boom.
A longer boring bar was needed for the lower hole on the headstock so i quickly made one on the Huron milling machine using some 35mm en8 bright round bar.
Once the line boring has complete, all the old bushes were removed and replaced with new, then reassembled with new pins.
Hope you enjoyed the video.
Thanks for watching!
Don's stress Olly, what may be routine and mundane to you is either nostalgic to the Old Timers or fascinating to those of us that don't do what you do! Keep up the awesome content! 🙂🦘
I never get bored watching your videos, and I look forward to all of them. The best part is watching how your mind works.
Would be nice to see the little forklift getting some much deserved love&care. It makes most jobs easier/possible...
Sunday morning breakfast entertainment sorted 😏. As I mentioned at Emley Moor, It's good to relax and watch how other folk tackle work issues. Especially after a week of seized components, parts availability issues, and hydraulics full of "mushroom soup" 👍
I will watch anything you film, every job is different including the trials and tribulations of line boring headstocks or pivot joints like the Matbro. That incidentally was the finest fixing job i have seen in a long time, a wonderful effort, you put your hand to the plough (so to speak) and didn’t turn back.
Great video yet again Ollie, your analytical thinking and practical skills are a really very good, overcoming hurdles with sound thinking makes your work a pleasure to watch and advances your businesses reputation immensely.
Thanks for allowing us to come along!
Yup another brekkie vid . Yes ollie we have all seen you line bore before however its the way you go about getting the job done . Its that damn the bars not long enough ....ill make another . This is why i guess most of us enjoy your videos as most of the time you're thinking out the box on how to do the required job . Great video as always thank young man
Discovered your channel last week, fully addicted n working through the back catalogue!
Good morning Oliver. Watching ye make a tool to make a tool to do a job. Nice with a coffee on a Sunday morning.
Yet another job that on the face of it looks straight forward, but you really had to think outside the box to get it done. As others have said, it’s not mundane for us. How you work through your problems and explain your thought processes is great to see. Well done again Oliver
Yes, first! Every sundaymorning a treat! Thanks for your nice work.
thanks. of genuine, honest videos.. Esko from. Helsinki
Yes another awesomeness instalment. Film all of it please.
Enjoy watching how you work through the job start to finish and nut out how to achieve the end result.
Keep up the great work Oliver.

I'm always impressed by your can do attitude even when you are obviously frustrated by how abused some jobs come in, and your ingenuity to just get it done and done right and often better than original.
Another excellent repair video great job Oliver
Another quality job completed, thanks for sharing this weeks work. Brian from South Yorkshire.
I'm a bit late to the party this morning. Good excuse for a second coffee and a lie in.
Almost 50K subscribers Ollie, not bad at all for a channel like this in about a year. You will be catching CEE up at this rate.
A great video for my Sunday morning, I love to see how you solve the issues that come up as you work. Thanks Olly!
there is something therapeutic about ure work
B.S Free Content .... Priceless and Beautiful to watch...
peace
Another belter of a video olly never a dull moment always learning new things I’ve been a mechanic and engineer for over 25 yrs I worked on hgv cars farm equipment etc your videos have helped me so much I have stage 4 lymphoma and during my chemo journey your videos have given me that little spring in my step high quality work and precision allay happy with your videos mukka god bless keep doing what you do because so many of us love the honesty and hard work you do all the best
Thankya Oliver, been enjoying your content for a bit now, am looking forward to watching this one.
great show' job well done .hope to see you next week'
that made a huge difference. Great job keeping that jcb in service again ;-)
Excellent episode, as usual.
Thanks Oliver 👏👏👏👏🥇
Yey! No. 2.. Brekka and Snowball - Yum!
Another great vid. When you're drilling holes, instead of having a constant downward pressure, just relax the pressure every 5 seconds or so. It'll break the chip and help reduce a Leeming Air Show around your drill. I'm sure that S power has a facility for skipping an arc. Perhaps you can incorporate that feature to not fill the threads up with weld. Or drill it through if there's room and tap it from the other side.
Better than new , nice one 👍
They must be working to 'half a brick' tolerance at JCB these days!! Better than new for sure now Ollie.
Need a tool, make a tool!.... 1st rule of engineering...👍👏👏👏👏👏
Great video I never criticise but I could hear my college lecturer screaming at me when holding the plate in the bench drill 😂😂
I spent a few years driving around the Western Australian desert line boring mining equipment. Just a couple of things I thought might help. That threaded hole, have a look through your instruction manual; there will be a switch or button on the controller that will allow you to stop the welder while the torch keeps rotating, allowing you to ‘skip’ over the hole. Screwing a brass set screw or the threaded end of a brass bolt into the hole just flush with the bore helps protect the threads and is soft to drill out. Bore sizes, I found on most machines I worked on, they were designed with nominal size bores. Your pins were just under 50mm (from memory), that’s to fit a 50mm hole + a bit of negative tolerance. You will find the same for bushed holes, bore a nominal size hole, the crush and clearance is machined into the bush by the manufacturer. Always check as there are exceptions and this is just my experience. I enjoy watching your stuff; keep up the good work and I hope this helps.
I think the best thing you could do about how much footage to show of any long operation would be to show it in fast forward, that way anyone that really wants to watch it can slow down the playback speed.
Ollie as usual good work, Somerset mike.
Good stuff. Thanks for making this video
Well done tricky job went well .
Love ya Work. from Australia.
good repair.
cheers
ben
Brilliant as always 👍🏻👍🏻👍🏻🇬🇧
You have some amazing skills, keep it coming 👌👌
Great video 👍I think the drilled hole had some Austenitic piece's better to punch off or use a die grinder get those super hard bits off.Done a proper job 😊
A very simple way to plug a hole when you don’t want to damage it while welding ! Install a brass screw . They are readily available at any electrical supply shop.
looks like another long job for you. Line boring takes awhile and that was a bunch. thks
Regarding the line boring, while we have seen the cutting before each and every other job's set up is different with its own little snag/ arrangement to overcome, so carry on.
If you film it we will watch it. No matter how long it is.
As long as you don't remove the standoff bolts that you've welded to the workpiece, you should be able to remove the bearing blocks and mounting brackts to get access to both sides of the boreholes. As for not having space for the welding head, you should be able to cut some 25mm spacers to bolt between the bearing blocks and the mounting brackets to give you extra clearance.
🙂a bit of aluminiun in the treded hole.. easy to drill out.. your dooing good work sad the new parts had bad tollerances..
Sehr gut gemacht! 🙂
Mornin Ollie from Florida USA!
Jolly good show, ol' boy.
Maybe braze those threads in rather than the plug?
See you next Sun mornin dark n early
I did wonder about why you were using genuine JCB parts. For those wear items like bushes, pins and links, Vicary replacement parts have always (in my experience) been as good (if not better) than JCB ones. Good job.
MM77 Approved 👍🏻 👍🏻
Great vid. Regarding the speed of the bore welding surely setting the bore to a larger diameter rather than the smallest would slow down the rpm? Bigger the bore the slower it would have to travel
@8:53 You said can't go any slower due to bore size (40mm). If the controller calculates the weld speed by bore diameter, it would rotate slower with a bigger bore diameter. If you want to go slower with the 40mm bore welder, you could try to set the controller to a bigger diameter, say 80 mm, then the weld speed would be half of the speed you did have....🤷♂️
What does that motor weigh Oliver as the bar bends a bit when it goes on? Nice work as we see all the time well done. You could make a copper bung to cover the thread holes. Use a copper piece a lot when filling in holes.
grat video again
JCB: make it loose, make it wear out and make more money 💰
Bored watching you line boring, never. Your always doing different equipment, think its as interesting watching you work out the problem as it is watching you go through the process, I could see you thinking about improving those wobbly holes on the new parts. Are you going to do any work on those left over parts?, only if you did you might have spares for when the next one comes in. 👍
I am surprised you can’t slow the SPower down anymore considering the rig was built for bore welding as well as line boring. Have you talked to the company about it? Maybe there is some setting that can be changed.
Bon Boulo😆😆👍👍
👍👍👍👍👍
32:56 possibly a piece of copper threaded the size you need would be better but I’m only guessing.
I’m commenting before you do it so I’m hoping your method is good.🤞👍
Or maybe some carbon rod?
Copper was my first my thoughts as well, I just waited until after watching before commenting. It's good when used as a weld backer as the steel doesn't fuse. Also if it was left proud would be able to see the colour after line boring
@@guyliversidge2676that would burn, and could also cause a hard spot
@@guyliversidge2676 yes carbon rod but it’s a product he may not have to hand, copper the same.
That’s possibly why he use steel.
The main thing is the job turned out good.👍
@@Paul-FrancisB yes copper is the perfect way to go it’s soft so less chance of the drill wandering also.
I’m sure Ollie will know but he may not have copper to hand, but our comments will help others also.
Better than Kurtis
The threaded hole in the bore, when I first saw it, I thought why not put a hex drive set screw in it... Then I saw the link with a bolt broken off and thought, why not just drill them out and use a through bolt like the rest of the pins? I know that access restricts that, but a threaded hole in a bore is pain.
How do you find the quality of your new line boaring gear, seams like good value.
Does increasing the bore diameter setting on the borewelder maker it go slower? To me it makes sense that a larger bore would take longer to do a full rotation. So setting the value higher would reduce the RPM, is this not the case?
I was thinking the same, that the controller would try to keep the SFPM constant, so larger diameter would be lower RPM
It could be a durr moment 😂😂🤔. The theory is sound, this is why us men never read instructions, engineers even less so until really stuck
Hi Oliver, great vid as usual. Just wondering why you use some sort of lube when you're drilling or milling but nothing when you're line boring! Just curious!👍
Could have used a grub screw for the threaded hole
Centering Cones!!!!!!!!!!!
For the number of JCB machines you do, not sure how long lasting they are for the money.
Need to consider how many are in use compared to how many need repair…
Aftermarket head stock assembly with very low quality compared to the JCB tight pin fits.,
Kurt could not have done a better job that that was magnificent, yes I enjoyed that great thanks bud
You could have made that threaded plug out of copper. Weld will not stick to it.
Wouldn't be worried by another line boring video, you gotta make videos that fit with your work, not work to fit videos.
Dickere Bolzen statt aufschweissen oder ne Buchse rein. Das Aufschweissen macht die Sache nur unnötig teuer. Und die Bolzen sind ja sowieso verschlissen und müssen neu.
🇦🇺🦘👍
Is it me, there appears.to be no sound with this video
Must be you
Mines OK as well.
