In this video we are line boring and bore welding to repair a Front A-frame off a Caterpillar 740 Articulated dump truck. The main pivot position on the A-frame is worn out so we are line boring and bore welding to bring the bore back to size to fit a new spherical bearing. We are using our Sir Meccanica WS2 portable in-line boring and bore welding machine. First is setting up and tack welding on the bearing mounts for positioning the line boring machine. We need to line bore out the material before bore welding to build up new material and then boring out to spec. We also chamfer the bore and drill in the grease port. The job is completed by cryo freeze shrink fitting the new bearing using liquid nitrogen.
In this video we are using:
- Sir Meccanica WS2 Portable line boring machine
- WIA 500i Weldmatic welder

I feel the urge to smash a like button every time Kurtis answers my silent question, like it was with the oil groove :) Tons of respect for the quality of your work. It's very inspirational!

@jimpumphrey7713 2 года назад

It really amazes me how you know that equipment so well that you can set up the speed, feed, volts, amps and anything else that needs setting, and complete a perfect bead in one pass. Great job.

@thepagan5432 2 года назад

Once you have done a job a few times it becomes second nature with feeds, speeds, amps etc. But, I have to admit Kurtis does appear to be silky smooth with his set-ups.

@stevevanvalkenburg5449 2 года назад

Great job, as usual, Kurtis. I've had to repair some bearing holes on large hydraulic cylinders when the owner let it get to the point the bearing broke down, literally in pieces and pounded them into the housing. Needless to say, now the job became a real bastard as hardened bearing chunks were embedded in the housing, couldn't be machined out, couldn't weld over them. Had to cut the part off and make an entirely new end. Entirely needless work. Keep up the good work, love watching a pro work.

@cripplecreeksawmill 2 года назад

KAAAHHHLLLL, at 4:00, when you ask about the single-split-race spherical bearing assembly: 20+ years ago (taking machine night classes) I had the opportunity to take a graveyard-shift tour of a bearing factory near Trenton, NJ (in the USA), they manufactured spherical bearings of all sizes up to around 16". The answer to your question is that they use a hydraulic press to push the inner race into the outer, the whole thing was surrounded by a steel cage/box, and sounds like a bomb going off when the outer race snaps back. The operators got a KICK out of seeing all of us young guys jump! I believe it was an 8" or so bearing. Keep up the good work👍-Andy

@ja-bv3lq 2 года назад

I've helped many friends do many bearings on their vehicles, and many of my own where I've put the new bearing in the freezer before we started working on the car... then, when ready, heated the knuckle / housing with a propane torch before massaging the bearing in. Watching you literally DROP that liquid nitrogen-cooled bearing in place makes me question my worthiness! 😆

Thanks Kurtis, Karen and Homeless, Kurtis have you ever experimented with using shoulder bolts and jam nuts to mount your linear borer to use a longer reach without as much deflection with the increase in shoulder diameter? Just had a pain of a brain fart... oh what a relief it is... Nice RC Copter in the backyard

@94XJ 2 года назад

I think you need a big CNC boring mill. Yes, it would mean a huge concrete footing, shop modifications, a ton of expensive tooling and fixtures but...now hear me out...it would be really cool. 😁 Excellent work as always! Good to see that "goin nowhere" test. The safety officer would certainly approve.

@SeanBZA 2 года назад

They split those bearings with hydraulics, using a mandrel with a wedge forced into it to split the bearing at a score mark with a sharp edge, machined into the surface. For the single side ones you just have the single score mark, and a cage to hold it when it cracks, and then you use the elastic range of the hard tool steel to pop the cryofrozen ball in, there is just enough elastic range to get it in. If it breaks it was going to fail NDT anyway, as there was an inclusion in there somewhere

@zoltannagy1813 2 года назад

Great work (again) Kurtis and excellent close up shots and video editing in general. (Karen deserves a pay rise) Just one question... instead of having to remove the cutting tool to measure the bore, can't you use an inside (spring) caliper to size the bore (without removing the tool) I've seen this done by horizontal boring machine operators where they have hardly any room to move in situations very similar to yours? Cheers.

@CuttingEdgeEngineering 2 года назад

it wasn't measure the bore that was the problem it was advancing the tool in the tool holder

Had a line not moving and found motor drive pulley had sheared drive keyway chewing outinside OD of pulley way out of spec and replacement parts have been on backorder for awhile so had to bore out, press fit oversized shaft then re-bore and broach keyway to size as we dont have any of that snazzy looking line boreing tooling you got. Basic lathe, press and hand welder. Would love to have some of your tooling as would make life alot eaiser. Excellent job as always making it look simple. Always good when things goto plan...
