CAT 627 Push Plate

[@repalmore]

For the mismatched profile, I would ask the customer to push on it with a dozer or something like that. I've done that with a blade skin that was bent more than it should. Welded the heck of top edge than had the dozer push on a ripper of another. had to move a few times to get it all pretty but turned out really well. Customer was happy because he got his dozer back that day instead of waiting another day or two to get the skin rebent.

You could wrap a high strength chain around the unit and place a hydraulic jack under the chain to press the profile down better.

Hey Paul, at the 7 min mark, you spoke about removing the remaining weld. I have recently been a convert to using flat carbons. I run a Pro Arc torch and they have an accessory button that replaces the original. I’d imagine that red arc have the same. It’s a game changer, try it, you’ll like it.

[@blueweld75]

Dude thats a great idea to fill that gap. I dont see anything wrong with it. Its just a consumable wear plate. Now I with that I went and helped inspected a blast room built to AWS D1.1 specs. We caught them slugging some double bevel flare groove welds with rebar. We made them cut it out. But for this I see no problem but I also dont have the experience like you to make the judgment call. Rad stuff as usual. Also the video of the one handed overhead weld. Thats like a beer poster right there dude.😅🤣🤣🤣🥲

They make them 3/8 thick so they’re have to be replaced often at 500 bucks a pop ! If they made things that lasted forever they would make any money selling replacement parts And I bet those price of those plates have gone way up now hell I’m paying almost $500 for a 4 x 8 sheet of quarter inch mild steel Here in New York Question have you ever tried the flat carbons they’re perfect for Knocking off those old welds you could even get a nice bevel on a piece of plate if you had to with those I use them all the time And another great video

[@Kc12v140]

What if instead of a solid plate, you ran horizontal strips about 4” wide. Then you wouldn’t need to template or get anything bent. I would think it would wear just fine, a bit more welding but a lot of time saved in fit up. Might be worth a shot on the next one

[@carloskawasaki656]

Ya just gotta love jet arc! I know I do. I describe it to people as being like plasma cutting but being able to control the depth. I have never gouged with a plasma unit, and I'm really not too interested, Anyway, great video. Looks like it was hard to find that perfect position when doing that overhead. Looked like it was just the right amount of too high to be comfortable.LOL Be safe!

[@rickbray7100]

Always think back to what my buddy the welder said. He worked at a trailer/ dump box manufacturer up here in BC Canada. The air arc or as they affectionately called it the unwelder. When ever the crew heard it every helmet in the place lifted to see who screwed up

[@SteveCoffman-x6s]

Nice job young man.

[@roydawson4882]

Should have sprayed a bulls eye on the back ,nice clean job.stay safe.

[@Bigmike3406E]

Awesome ! I myself also use 3/4 but I put on corner plates also especially on 51s 57s because sometimes they get pushed around a sweeping corner in the cut and with 9L and 10N even with cushion push dozers they can tear the corners up fast on a stinger especially pushing with a ripper cat with a conventional dozer blade. You have to hook it in the corner to keep from popping the tire with a corner bit.

[@nicklambing9268]

I would guess the thinner and smaller dimension replacement wear plates were like that due to the problem of matching the face profile. By using the smaller, thinner plates you could do something exactly like Robert Palmore indicates to shape the material, as needed, in the field. Every impact area will be different depending upon the shape of the surface that contacts it, causing it to wear attempting to replicate the shape contacting it. The smaller, thinner material can be shaped on sight, whereas, the thicker, larger dimension material needs to be back filled like you are doing, leaving open space between the parent material and the new wear surface. As the plate gets thinner there is a point at which it will begin to flex, due to the open space between the two surfaces, resulting in cracking and possible earlier failure. Just a thought, regarding reasons behind Cat selling the thinner and smaller dimensioned material.

[@OFW]

That is a good point but even those 3/8” plates are very difficult to manipulate into shape and will still have a gap under them. Either way it’s a pain.

[@nicklambing9268]

@@OFW I wouldn't have thought of that until I saw Robert Palmor's post, where he indicates he has done something similar when applying blade skin. Right off it seems logical to apply a thicker wear material, lasts longer, should be stronger, etc.. I began to consider the thinner smaller size may be a factor when faced with application in field conditions. Considering at a very small instant in time while the dozer blades and the wear facing are in contact, nearly all of the force can be applied to an extremely small area, thus unthought of stress my be applied in ways we do not anticipate and metal oil canning might occur. This extreme stress might be applied time and time again throughout a work shift. I didn't mean to suggest your approach is wrong, but after Robert's post I began to consider why the heck would a company like Caterpillar sell the smaller, thinner replacements. Repairs such as this are often best done by old timers that have found things out via the school of hard knocks over many years that defy a persons thinking. I am 80 years old and have discovered ways of accomplishing things I probably would have never considered at age 30 or even 60. You do good work and I enjoy viewing your content immensely. My proposal was submitted for you to consider as a possible explanation as to why Cat might be selling the plates they are. Nick

[@johndoe43]

Hard to get that curve to match just right. Like plating a dozer blade. I did one once with 9 inch wide plates run horizontal. Pre curving like you did is the way to go. I used one half inch on the dozer. It was pushing single engine allis Chalmers scrapers. They were cool old units

[@jimsvideos7201]

Also if you were that company's full-time welder you could have welded the top and most of the sides and let a few days' running massage the bottom into shape then weld it. Either way it isn't going to fall off, and even if it does it isn't safety-critical.

Why do you suppose Cat put a layer of grease under the wear plates? Nice camera angles in this video. I especially liked the 1st person view as you welded up the left side of the plate. Would be fun to get an angle from beneath a plate when you’re using the plasma cutter. 27:28 strike a pose! 😂

The grease gets there from cracks on the original wear plate. They put grease on the outside to help with wear.

[@curtisharlan9230]

Hello you do good work

[@Blakes123]

I have a guess that they use 3/8 plates because it’s easier to bend to get the right radius. Also you talk about porosity is that when you get air pockets in your weld. If so how does it get there.

[@OFW]

Porosity is air pockets or contaminants in the weld. Used caused by dirty materials or bad gas/flux coverage.

[@JoeBribem]

The ejector plate pushes the material out of the can? Seems like a simple question

Yes.
