I know it's too late, but when fixing cracks in Al, you need to drill a hole at the end of the crack to stop it from propagating further, then you can weld it/plate it and it will be strong. But welding on an existing crack will just let the crack expand over time.
Plus that’s cast aluminum whole different thing
Also preheat the area before welding.
Shouldn't you preheat the aluminium to prevent tension caused by differential in temperature and the resulting cracking. Don't take my word for it, I have absolutely no experience with this material but it may make sense.
What you do is bring it to someone with a tig set-up. A spool gun is a bad choice for cast aluminum. Very bad.
Anytime you weld aluminum that has been in constant contact with oil you will have problems welding it. Wire wheels smear contamination into the grain structure of the metal. When I am welding cast aluminum with cracks I use carbide rotary file to chamfer the cracks wide and deep. I always tig weld cast aluminum and I slowly run the torch over the crack heating it just enough to slightly melt the surface which seals the surface and reduces contamination.
I worked for 45 yrs in the truck repair business. 25 yrs at Consolidated Freightways and 18 at Holland Motor Express. For used Cat parts check with Midwest Diesel Used Parts, Blaine MN. Never a complaint. CF had thousands of 3406 As, Bs, Cs, and Es. As far as I am concerned the 3406B was the best engine I ever encountered. When CF went out of business in 2002, we had 1987 and 1988 3406B's with 2,200,000 miles to 2,400,000 miles with one overhaul at 1,200,000 miles.Fabulous engine.
It is so nice to find a Technician you can absolutely trust, that knows his stuff and is willing to share his knowledge.

One of life’s greatest little pleasures. Watching the Welker family at work.
Enjoy watching you guys fix your equipment. At 80 I won't be doing any of it but still enjoy watching. You all are very inventive.
Always sounds funny when you call it a motor, when I went for my heavy duty training I was told a motor is electric and an engine was fuel fired. Still seems funny 55 years later I always drill a small hole at each end of the crack to stop it from spreading when heated. The tool that Cummins has is 6 inch lbs, has changed in N T to a different setting method now. Hope you checked the bearings when the pan was off, always something I did. Enjoyed your video, can’t wait till the end result.
I am not a farmer, but my entire extended family were farmers (all dead or retired now). The farmer's motto: well, she ain't pretty, but she'll get the job done.
Watching y'all work on that CAT makes me miss working on them before I joined the Army. They sent that work to civilian contractors and wouldn't let us do it.
Hole drilled at end of cracks plus heating the casting up pre welding. TIG also uses less heat than MIG.
Brian and Scott make a great team when it comes to mechanical work.
I always use a torch , heating the area to straw yellow , the cracks jump out at you. And absolutely drilling the cracks
I can remember when, aluminum welding was considered impossible. It's just incredible to see it being done.
Had a guy try yo weld up a hydraulic oil cooler on our 815 combine. Spent a good part of a day on it doing aluminum welding. ANY kind of contamination in any cracks would just chase. Clean means CLEAN! Not just mostly clean !! They are touchy !
There was an update / Service Bulletin on the bellhousing to block oil seepage in the mid 1990s. The Welch plug at the back of the engine got replaced by a plug with an O-ring and then you needed to grind a slot so any seepage could drain to the oil pan.
dont forget the 5mm flywheel washer to 3mm and the dipstick update with 11 gallons of oil
In the first video I told them about this, also updated bolts for the 1/2 bolt holes. Flywheel also has been updated and depends if you have the old style, and put the new style on. The old bolts are longer, thus the flywheel will not be torqued correctly.
The little F-134 engine I'm rebuilding for my 54 m38a1 jeep willys is like tinker toys compared to pulling this CAT apart. I like watching you guy's build different rigs, it's probably my favorite thing you guy's do on the farm. I struggle to do thing's, but i keep moving to stop the muscle wasting from this MS i have, but at least i love working on machinery, it helps me get through the pain, and the struggle of having no feeling in my left hand, and the weakness that messes up my dexterity. I just thank the Lord for what i have, and his grace and mercy
G-d bless.
Your whole family is an example of not needing school to be educated. You're awesome.
Its not the fact that its aluminum that it cracks its the fact that its cast that makes it crack. Thats why you preheat to avoid the cracks .
Yeah, cast steel has the same problem. That's why it is almost impossible for anyone to repair cast housings or cast parts. I remember the one episode where Kurtis (CEE Australia) attempted to repair a cracked wheel loader transfer case housing with spray-welding, did all the pre-heating, did not over-cook it, worked a few hours on it - and then during cooldown the part simply almost cracked in half with a loud bang. Yepp, cast material ist just nasty to work on... 😕
Awesome your subscribed to CEE also?
@@ilovemydad1416 As am i . Kurtis is the man when it comes to machining and repairing stuff
You guys are next level farm mechanics. Always impressed.
Don’t be discouraged on that oil pan, same thing happened on iur 2WS! And replacing that crank damper is a must! Truck will run smoother and good preventative maintenance
I don't always weld but, when I do, it's JB Weld. Lol.
😂
Real men doing real work!
You go to the end of a crack and then drill a hole to releave the tension in the metal and stop the running. Then plug weld the holes and cracks as needed.
Brings back memories of my 20s. The Cat 3406 was just coming out as a replacement for the 1693. Engine was lighter and more fuel efficient. Simpler as well.
Thanks for another great video Scott and Brian and Bob.
It was very interesting and informative and enjoyable.
Wow. Lots of busy engine work. All of you hang in there.
I agree on putting a new oil pan on. The old one did not weld up good at all.
Aluminum welding is not easy.
Brian is really a good person to have on the team. He did great setting all the valves and such.
Piece by piece and step by step you are getting the motor ready. Good show.
Extremely anxious to know what this engine is going into. Got to be getting close to you all revealing that.
Thanks for everything Welkers. This has been most interesting.
You all take care and be safe.
Waiting to see the motor finished and put into its new home.

i TIG weld alu so i use wirewheel to clean it and then a bit of heat to cook the oils out and then clean with acetone, dont use break clean it has chlorine in it and when heated might release chlorine gas
Man he is a top notch mechanic!!! Great to have someone like him to help out!!! Awsome job guys!!
11:03 Try drilling a small hole ahead of the crack then fill the at the end of the weld BBQ ead.
PLR
Pro tip, stack the clutch on the transmission first. Then stab the trans onto the engine and bolt it up, then bolt the clutch to the flywheel from the inspection cover on the bottom... works mint and you don't gotta fight the Trans getting stabbed
when I did my clutch in my pete, we just slid the clutch onto the trans, bolted the trans up then slid the clutch forward and put the bolts in through the service hole. I was surprised how well it worked.
This old man learned a lot just watching.....Thanks guy's and GOD BLESS y'all

When someone ask a Welker what they do for a living, their response should be…Everything!
I could say the same, but they seem to be on a mix of caffeine cocaine and Adderall, WOW they have a lot of energy, I'm just getting old and can't believe how much I used to get done, I need a nap
In all truth I have a good wife, and it makes all the difference when you have free time
I grew up on my relatives farms and you have to be self sufficient at everything. I was grateful to grow up with that because I have those abilities and fix everything myself now and I am self sufficient in everything I do. Served me way more than any schooling every would. The answer to your question would be "What do you do for a living?" YES. 😂
We were taught to figure it out, not to call someone for help, and we strive to not disappoint our elders, getting yelled at was possibly worse than a arse kicking, and to this day we still can hardly afford the parts to fix things let alone the labor bill, so you figured it out, I'm afraid for the next generation if they can't Google it with a phone, and have mom dress them and feed them they won't be able to succeed in life, pray for America
You should consider putting Brian on the payroll. He seems to be a good addition. Very knowledgeable, and a hard worker.
Brian is an independent mechanic. He isn't working for free.
He’s a joy to watch with all the special tools.
Oh he’s on the payroll.
They couldn't afford him😂 He makes great money being a "independent contractor" I bet
@@brucehobbs1734 LoL 🤣😆
Hi Scott, if you watch Western Truck and Tractor Repair, you can pick up some good tips and info. The guy work's on everything old or new, and does a good job explaining thing's. He work's alone, has his own company, but doesn't have every specialized tool, but can show ways around it. He was a submarine mechanic in the early 90's, and then came out doing heavy equipment. I like that if he makes a mistake, he show's it, he's a good guy who does good work. G-d bless.
We are very fortunate to receive little bits and pieces of your world. Wholesome comes to mind and to close every episode with “God Bless” truly touches us! Thank you for sharing your world!
Brian reminds me of dad, he was originally trained as a diesel mechanic when he was in the Army. I helped him rebuild a few motors when I was a youngster
It's "The Right Stuff!" Best leak fixer ever!
On the Cummins top stop injectors the t-handle torque wrench is 5 inch pounds.
are you certain pretty sure its 7
I thought it was 8 inch pounds
Welding anything cast. The best advice I ever had was plan a max of 1” per hour or it will keep cracking. Don’t let it get hotter than you can hold your hand on. I am not a welder.
A little too late, but word of advice from a welder:
1. Always drill out the ends of the crack.
2. Always grind a bevel in the crack.
Especially on aluminum, or the crack most likely will expand without you even noticing it. Also, aluminum mig usually lays best with a near 90° angle of the gun. A ever so slight angle towards the direction you're going is fine
The tool for Cummins is 5 inch pounds not foot pounds (5 foot lbs would open the valves and it wouldn't even run) and yes I use it for valves as well as the top-stop injectors, Cummins is the easiest engine I have done an overhead adjustment on yet.
2nd truck I drove had a C-12. Was running a lot with my old timer buddies one had a Juiced up B model. Other one had a N-14 that would make his turbo glow. My poor C-12 played hell trying to keep up. Good motor but running heavy in the mountains I’m glad I have a 16 liter now.
Scotts learning some next level mechanic stuff from that guy !! Team work makes the dream work !!!
Aluminum welding is amazing but it can be a bear when I used to weld alot I had separate wire brushes and carbide bits and all just for for Aluminum
You should get a tig welder
When I was teenager I sent a rod through a mercury outblard block. I borrowed my neighbors tig and welded it up piece by piece (like a jigsaw puzzle). Never forget look in the parts guys face when I bought 1 piston and 1 rod for the 6 cylinder..
You need to get a tig.
Brother 23:10 Scott the only possible way you could have stopped the cracks would be to bake the pan to red hot and then weld it quickly before cooling below red. Forgetaboutit 😏 you did well replacing it Bro 😎 no trouble down the
Line. 😏🖖🏼🇺🇸
Tony Fast is an excellent aluminum welder.
3406 Cat pans were notorious for cracking under engine vibration which is probably why your dealer had one in stock. It's such a large casting that it was difficult to control the cooling. I think I saw something about them having to modify the alloy they used and slow down the cooling process.
Always push your welds when possible. Prep work on metal is crucial.
You turned the engine backwards when finding TDC, also you do not adjust the valves unless you have the Jacobs Brake mounted. Went to a Jacobs Brake factory school in the 80's and that what we was told. Also you could update the Brake and make it from a 3 point stand to a four point stand, change the adjustment screws and make it a 346B + Brake and get 25 HP more braking power.
Did the top set on our N14 in our versatile this spring. Had a injector go bad so we were already in there. Then new injector only lasted 5 hours 😢. Had to put another in. All good now.
As a welder I know your challenges. Sometime new parts are necessary. ❤
Crack tip opening displacement - did you account for that? A drill hole through the crack at each extremity of the crack would relieve the tension before welding. If not the tension might continue, hopefully the strength of the weld will prevaile. Good luck.
So cool you let us see the master show you thanks so much for filming that
Its great to watch a master of his craft
great video . Thank you guys
When I find TDC on those 3406 and c15 cats I put a paint pen mark on the damper in line with the fan belts, easier to do a top set in the future
Has that new damper rubber or silicone filled. I worked with dampers for over 20 years with
Simpson Industries in Litchfield Michigan.
More people should pay attention to dampers.
They do wear out.
Good job Scott !!!!
Excited for a new project!!!
You put 3/8 bolt in hole on right side of rear housing pinning engine either its on 1 or 6 doesn't matter. There is one on left side too but with starter and in truck impossible to get at. If on #1 do intakes 1,2,4 and exh 1,3,5 roll engine 360 degrees and do other half of overhead. Jake brakes if on #1 was 1,3,5 rolled engine 360 degs and set other half. Intakes 0.015 and exh 0.030 jakes lash setting on tag on jake housing. We only pin engine once because we paint mark damper inline with fan belt so you don't have to have help pinning engine again. They do make auto pin its spring loaded but I broke mine bent the pin. ALso see many who leave pinning bolt in and then start the engine. Oh thats fun getting that bolt out after end bent over
Save the oil pan for emergency use. 8:05
Preheat the metal before welding.
That'll be one heck of a repower on that manlift you've got it with. Get you up and down way faster. Probably gonna have to bulge the engine cover a bit.
Americas favorite diesel mechanic is back.
You're teaching us all Brian and LegArms! That old Cat is gonna' have some Grunt!
Aluminum is tricky to weld no matter how good you are. You got it, blame Nick :D lol. You have to treat aluminum like you do with cast iron, preheat the entire pan. I really hope you went ahead and installed a new front seal, hate to see you in a few months, having to replace it while in the middle of harvest. Most important thing to think about, you're there already, change it, money ahead later down the road per say.
It's cool that Brian let's you film him while working on your equipment.
Preheating the work prior to welding will help with the cracking
PDI Diesel out of St. George UT. the best place to get parts for your Diesel equipment
PDI is top notch stuff, they redid a 3406B and it went from 400HP to 450+ HP the trucks they have over there that the owner shows off at truck shows is sweetness!
I’m surprised PDI doesn’t have a oil pan
They are great. We feel embarrassed with our work compared to theirs! I'm sure they had a pan but we didn't know we needed one until after we had ordered parts.
I literally just today adjusted valve lash/clearance on the truck. If I only heard this advice 32:06 before, it would be much easier. Haha, had a good laugh 😂
The problem with the sump is that its cast aluminum, therefore to weld it with no issues you need a big gas head to heat the whole sump up to close to weld temp. Then you can weld it quite easily.
Aluminum oxidises so rapidly you cant even see it, thats why you need to get it very clean. The oxidised surface is extremely hard and makes it so hard to weld.
you all work together as a family
Great job guys..... can't wait to see where you put that engine.
Thank you Brian
It is also way more precise and convenient if you pull the engine and ship it to him to run the rack.
Great video guys.
Maybe I missed it or maybe you're going to do it another episode but I can't believe you tore that all the way down and didn't put rods and mains in it. And if you did I'm sorry for the derogatory comment. Still digging you guys channel!
Also good to sweat the aluminum, it also holds moisture ..
That's all i used to use for aligning clutches during install on semis. You can whack them with a hammer if you have to.
For the oil pan cracks; I heard *Flex Tape* works if you can seal a screen door and make a boat with it the oil pan shouldn't be a problem
You can use different cold weld products on oil pans. We've done it many times.
The 9370 is going to love having a heart transplant
A heart of gold?
Watching and looking pretty is a great way to learn
You guys are my favorite TH-camrs ❤
It's going to be sweet, to hear that motor in the side by side!
As with any cast metal, you have to heat the whole part, weld, and put back in oven and turn the heat down slowly. Or, just go online and find one! 😆
Can't wait to hear it running...
YES the KEY . it is a MUST...
Next engine get a proper engine stand for it. And a separate cradle for the test running it in. 25:01
Let it go LG. New pan
Great video as usual. Love that you all reuse and refurbish.
I love when you work on projects
You scored big with Brian.
oTrue I don't know THE truck this is going into but I DO know that ya'll were blurring one out in some earlier videos...I would guess it is going into THAT one. I would also guess that THIS video was recorded earlier this spring (March?)...give away was the moving of kitchen cabinets. Also the Big Bud you were working on earlier this spring is clearly apart in the background...plus you have the pro-mechanic now working on this one. Hey I like mechanical mysteries!
At 2142 behind MR. WELKER is a beast waiting on that engine,me thinks!
I see a new oil pan in your future
Enjoy this video have one just like it been thinking about updating could you please elaborate on the turbo and injector upgrades?
That is tuition that will pay a dividend, unlike most of college tuition.
I feel so much smarter now after watching this
Master Mechanic work by Brian
Now that was educational. Great job
