I do not get your logic ?
You are very keen on using parts to original specs, and found the correct high nut type.
But then you trade off on the bolt type - even after explaining the importance of why they should have the specified non-threated length.

[@CXensation]

@@squatch253 There is always a story behind ...

[@pnwRC.]

@@squatch253 Not to mention that aftermarket bolts wouldn't have the CAT logo on them. Once you explained your reasoning for methodically placing the logo's identical to one another, it makes sense to sacrifice the NON spec threads in order to keep the logo for quick visual reference!

​@@squatch253 great explanation! Beside, having all of the logos facing the same way kinda looks cool!

It's a trade off - you can EITHER have "CAT branded" bolts, or "to original CAT spec" bolts.
But you can't have both.

Silver soldering advice: Use Harris black flux. It withstands higher temp without burning away like the white flux. My favorite solder is Harris Stay-Silv 56. If you need to do separate joints close together, you can use Stay-Silv 45 first, and then 56. The 45 is a slightly higher temp. I also use Stay-Silv 15 because it's cheaper and widely available, but it's a bit stickier. Works better for filling a gap.

[@lwilton]

Tip on silver soldering: it is _impossible_ to silver solder over soft solder. It just doesn't work. You will have to do your darndest to get all the soft solder off of everything before you will successfully silver solder to those parts. Even then you may have some problems, since soft solder tends to bond chemically to the top few layers of atoms in the target metal.
To actually silver solder, you need about three things: clean surfaces, a lot of appropriate flux, and the right amount of heat. Clean the joint, use a paste flux that you can smear over every part of the connection area, and then heat the joint up to a low red heat, no hotter. Just like soft soldering, you don't want the heat directly on the solder rod/wire; you want the metal hot enough to melt the solder. If the joint is clean and well fluxed, to solder should pretty much flash wick into the joint at red heat. Without sufficient flux, or too high a part temp, the solder will ball up and fall off.

[@scottyuhrich]

Couple of points on soldering. First off, even some soft solders now have a percentage of silver to them, especially the lead-free ones. Harris Stay Brite and Stay Brite 8, for example, with 8 having a higher silver content and better bridging capability. What most people refer to as silver soldering is actually brazing with a solder stick that is 15% silver. Then there is cadmium free silver solder that has a 55% silver content and is sold by the troy ounce. Obviously, the higher the silver content the stronger the brazed joint. 55% silver solder is used for high pressure applications and brazing dissimilar metals such as copper to steel. Stay Brite 8 makes a good joint that is capable of withstanding a couple hundred pounds of pressure but can fail from vibration. 15% silver sticks deliver a joint that will stand up to vibration.
Soldering is not a chemical reaction and does not occur on the atomic level. Rather, it is a physical process known as capillary action. When the copper is heated, the pores expand and the solder flows into them and then is securely anchored in the copper when it cools, but the seal between the two pieces consists strictly of the soldering material. This why soft solder requires flux to clean out the pores so the solder can fill them. Flux is not nearly as necessary when brazing with 15% silver sticks because the higher temperature required for the solder to melt and flow, burns aware almost all of the impurities. It will improve the ability of the solder to flow and helps with copper that can't be thoroughly cleaned, but I have made thousands of joints without it. I always use flux when soldering dissimilar metals to insure a good joint.
I have brazed successfully joints that were soft soldered, so it is not impossible. But this was always on joints that were done with lead free solder. True 50/50 solder that is made of 50% lead and 50% tin may act differently, but i have never tried so I do not know.
An oxy/acetylene torch is good for brazing, but I tend to prefer a Turbo Torch connected to a B tank of acetylene as it heats a wider surface area and helps eliminate missed areas in blind spots. As always when soldering, you head the joint, not the solder and make sure you heat the entire socket so the solder flows all the way in.

The thoroughness in all your videos on this crawler is just amazing. As is the fact that there is literally not a bolt from it that's left out. Also it sometimes takes me to watch it twice to realize how well you choose filming angles.

Very good points, particularity on the grip area. We always took that into consideration in architecture school for shear calculations in particular. The threaded parts has a smaller cross section, which of course it can't take as much load.

[@wilsonlaidlaw]

Squatch, I regret to advise that you may have great difficulty silver soldering on a joint that has been soft soldered, no matter how well you clean the old solder off. I had that problem on a large model of a hot air engine, that had been badly repaired with soft solder. I spend ages cleaning off the lead/tin solder from the oil supply pipes and brass unions but the silver solder just would not flow or take. In the end I succeeded with copper-phosphorous rods (Cu-P 701). They are only slightly higher melting point than silver at 730ºC (1346ºF).

As an aircraft mechanic for 36 years, retired now you always torque nut never bolt head. Maybe it doesn't matter with your application. Just my 2 cents, awesome videos love them all.

Same here, engineering documents specified additional torque by bolt size when torquing the head.

Additional info, in a “loose” hole like these, torquing from either head or nut is correct

[@danielyoder5928]

Once you have cleaned all the old solder off and out of the joints and assembled the manifold. Before you start to silver soldering the oil manifold back together, put a purge on it using nitrogen gas. That will prevent oxidation of the copper inside the manifold. The black oxidation that is formed while silver soldering is hell to remove form the inside of piping. It can break loose and travel through your bearings. If you cannot get nitrogen gas then use argon.
BUT DO NOT USE BRAKE CLEANER TO CLEAN THE PARTS!! IT AND ARGON HEATED TOGETHER FORM PHOSGENE GAS! USE A NON CLORINATED DEGREASER. ALSO DO THE SOLDERING OUTSIDE IF YOU USE ARGON
The purge doesn't need to be a high volume of flow, place a vent hole high on the manifold and feed the purge form the lowest point.
Good luck and practice first

Apart from getting silver solder to stick once a joint has been soft-soldered (every scrap of the soft version has to be removed or the hard will just run off) you also run into the problem of any lead based solder left vaporising at the higher temps needed. Mucho ventilation needed and preferably some protection. Good luck.

Depending on the soft solder used a new silver solder joint might be very difficult. I don't know about the new antimony/tin plumbing solders but the old lead/tin solders had to be completely removed (like nothing but copper or brass visible) before attempting a silver solder joint.
The flux is also important - I use mostly Stay-Silv unless I expect to have to hold the joint in heat at which point I use some of the black flux (can't remember the name but it's commonly use to braze carbides).
Finally - heat is what you need more than temperature. O/A is ok if you have a good rosebud tip but I tend to use a large Goss propane torch to get the whole joint hot at the same time. Once the flux goes glassy and looks like a still pond the silver braze should suck into the joint. If there's gaps of .010" or better look for a gap filling braze.
Just some advice from someone who's been there.

[@KennyKizzleRustyNutzRanch]

It sure looks great with the swampers on it, buddy!! An awesome machine it will be. Once you get that oiling manifold figured out, and the rest of the track work/cab work done on it... She's really going to be a nice machine (not that it isn't already)!

[@kevinknight470]

Couple of things for silver soldering. Practice on something that is expendable until you are totally comfortable with the process. Surfaces must be completely clean and ask some pros about flux. Don't be afraid to put some serious heat on surfaces, as in cherry red. That was the temps I needed to get silver solder to work. Practice, practice, practice. Thanx for sharing, great video.😃

[@mattydare]

Trapped between a rock and hard place?
If it were to be worked it then I would firmly recommend bolts to spec. That shoulder before the threads is designed to stop lateral movement between the grouser plate and track chain.
It's not going to be hammered so stick with the logo bolts.
Maybe go gentle when turning coz those huge plates are going to grip and apply more twisting force. Also hit em with the torque wrench after it has been used.
If no-one has already mentioned it - torque from the nut side. That way you are tightening the nut without potential binding resistance and flexing from the bolt shaft giving a false reading.

I know it may hurt a bit, but you could take the oil manifold to a local HVAC tech. However, get yourself some soft solder and some flux. We use stay brite by Harris. Don’t be afraid to get both sides warm, especially the cast portion. When the flux starts to bubble, you can start dabbing with the solder. It will wick itself in. Just let it cool slowly for maximum strength.
