Hello My Friends in Queensland.... .I would love to see a real short segment on cameras, lighting if any, and edit software you use Karen.... .I really admire your technique.... .you are a natural at make very informative video that is understandable.. now if you can only get George and the Train to cooperate., and maybe help Kurtis from getting his tongue wrapped around his eyetooth so he can see what he is saying.....the outakes are always fun to watch... .I know when I am on camera, it sounds if I just drank Tea Martunnies or a Bubble Durban......... .thanks so much.... .best wishes from the other 'Sunshine State' Paulie Brown

[@raderallen1]

I'm a machinist for a large CAT dealer here in the US and we flame spray almost every single part that comes in for repair. It's cool seeing someone with a large viewership doing the same thing. I would like to point out some things I do differently you can try out for next time. There is no real advantage to putting a thread into the under cut area. I've found that just running a fast feed rate like ~0.015"/rev while undercutting provides a very consistent but still textured surface for uniform adhesion of the spray. With a part like that with a 4" OD I'd run at around 150rpm with 0.006" feed rate when turning back to size with ceramic insert, it sounds slow but that spray is almost like sandpaper and turning too fast will literally melt your carbide cutter, like what happened to you. A seal area like that probably has a +-0.002" tolerance from CAT so I turn it to the top end of spec and then lightly polish with 240 grit paper. Going with a finer grit just exposes graininess in the spray.

[@g7majoh125]

It’s unfortunate that he probably didn’t see this comment

[@basketofdeplorables4253]

he didn't even get the engine right, it's from a C9, and a repair sleeve with green retaining compound would be better than new for this part.

[@raderallen1]

@basketofdeplorables4253 an OD steel sleeve would work here, but flame spray has a higher abrasion resistance than typical mild steel and probably is a better fix in this application.

[@basketofdeplorables4253]

@@raderallen1 repair sleeves are not made from mild steel. they are made from material much better than the cast iron the pulley is originally made from. it would be a permanent repair, or worst case have to be replaced when the engine is overhauled again.

[@raderallen1]

@basketofdeplorables4253 most steel sleeves used to repair CAT components are from mild steel, rhe exact material is dependent on recommendations in the cat literature but unless it's a very specific use case it's not going to be wear or abrasion resistant. In fact, we actually use more cast iron sleeves to repair wear components than we do steel.

[@everestyeti]

Really cool that you've kept all the paperwork, must admit it's something I do as well. I think it's really good that you can use something that is 50 year old technology, not only is it a testimony to those that designed the equipment but to you for keeping it alive. 👍

pretty rainbow, love the addition of the shots of the area you live in. 50 yr old technology still has relevance

[@wayne6512]

I do exactly the same thing as Kurtis does, and I've also done an extremely lot of powder welding onto many different base metals. If you can master the art, powder spraying is really a game changer for many repair jobs.

[@waynecarr98]

Awesome to see you do something you haven't shown on the channel before.

[@Banerled]

*_Wow, I just wanted to say a big thank you for the amazing KZbin video! Seeing the process of repairing the worn seal surface on that crank pulley was truly fascinating. Dealing with a Caterpillar 3306 Engine from a CAT 637G Scraper tractor and the worn groove on the seal surface must have been quite a challenge. Your detailed step-by-step guide to metal spray welding using the Castolin Eutectic Rototec setup was incredibly informative. Starting with the prep work like machining down the worn area and applying the masking compound, followed by the metal spray gun pre-heating - it's obvious you know your stuff. And then, watching the part cool down and machining it again to specifications using emery cloth was a great way to show your dedication to precision. Thanks for sharing your expertise and the whole repair process with us. Looking forward to more engaging content on your channel!_*

One of the most beautiful processes to watch! And I’ll bet it’s exciting to perform as well 🙂

[@CuttingEdgeEngineering]

definitely a lot of fun and good to do something different

[@dougiebrown9318]

We used to use metal spray on both our 4.236 / 6.354 Crankshafts ( Perkins ) pilot bores & rope seal surfaces back in the 70’s.. By the 90’s we’d stopped using this method & reverted to inserting sleeves & we’d stopped machining rope seal cranks by then anyway. Back then some companies used to metal spray crankshaft journals although these were unsuccessful in the high revving engines..

[@battleaxefabandmachine]

I just cut cylinder counter bores for shims in 1 of those engines about a month ago. It was in a 50 year old bulldozer. Spray weld is pretty cool. I have never seen it done other than on videos.

[@austenmoore9782]

Being a farmer, with a lathe, it's so good to see things repaired instead of being tossed. Good job.

I grew up on a small farm ... I remember repairing items on the farm, because it was not worth the TIME going to town to find a new part (even if it was free, t was still cheaper to fix what you have! :) )

[@Jim-nm1en]

I used to do a lot of metal spraying in the UK up until 2005. We only used machinable coatings for bearing fitting diameters plus, we used ceramic inserts in the turning tools to machine at higher speeds for smoother and more accurate finishes. For seal areas we used a stainless steel wire spay gun process and ground it to finished size. Also , we had powder guns to spray ceramic and fused coatings which also had to be ground back to required dimensions. Very surprised you didn't have any dust extraction as a lot of that stuff can be carcinogenic. By the way, the company that I worked for at the time, which is a major UK company, had and still does have nuclear power generation accreditation so the various coatings had to be as near perfect as possible. I have used Eutectic coatings in the past but they were for fairly basic purposes. The company , because of its size and prominence, could afford the higher end processes and tooling. Even in basic form though, metal spraying is a great money saving process.

[@rayleblanc7209]

I had no idea you could do that, and the tech has been around since I was a teenager.

[@goatsinker347]

Abom79 uses a misting attachment (at times) where a coolant is “misted” by an atomizer onto the insert. It’s a much smaller amount of coolant that is administered, keeping from messing up the area, while still providing some cooling action.

[@mashrien]

Right-o Kurtis, the hardness really surprised me (hah), I didn't think the sprayed material would be anywhere near that difficult to sand down.. I wish you had tested the hardness of it, because even tool steel and chrome seems to sand/rough easier than that stuff did. Awesome video and thrilled to see something different from the norm.

[@normcameron2316]

A long time ago I tried this same process in the same/similar applications. Didn't work that well. Spoke with the sales rep and the Tech guy, and they really didn't want to talk about it, like they had given up on the product. Anyway, since then I go with a sleeve, splash of loctite on the inside for sealing. If it leaks there is a pretty good chance the sleeve was distorted during installation. Or, just buy an aftermarket part.

[@anthonybernstein9698]

With your skill at repairing and upgrading design faults, handling all manufacturing problems, and all types of breakdowns you have a wealth of knowledge regarding CAT machinery, you might consider turning from poacher to gamekeeper. Instead of fixing a lot of obvious problems you could advise on preventing the problems. Every new model needs testing, and it seems that the customer after a few years finds the faults that you so capably fix.
