Thanks Dave, sounds like MAPP gas is not hot enough for silver solder if that's what my lines have? It was sort of gold-colored which suggested brazed to me (although I don't know the technical difference between them other than the fill material?). I used electrical solder so maybe that was my mistake. I do have some silver solder so I could try that if the newly attached ferrules leak. I obviously don't know what the heck I'm doing : )

Cheers,

many plumbers over here use mapp gas torches. you have to get the right torch though to have a hot enough flame. there is also many different grades of silver solder. from very high melt to lower temp. also there is non silver plumbing solder which has more tin in it so it has a lower melt point.

you can also get mini oxy sets that use disposable bottle of mapp gas and oxygen intended for hobyists, plumber and jewellers. if its gold in colour thats more likely to be brazing which mapp torches really wont do.

Yes, that's what I figured on the color. I do have an oxy set but used my MAPP because it's more convenient and I thought I was dealing with solder. No worries, I glued another ferrule on and so long as it doesn't leak, I'm good.

Cheers,

Silver Solder does have a gold/ bronze color when it is applied. Brazing these lines would not be practical on a production line.

Meanwhile back at the Ranch. The water pump is bolted on and the belt is tight. Waiting for 3 more gaskets from the Great Yellow Pussy Cat before I can fill it with antifreeze. The better oil cooer lines have been installed. The other's I did a temporary fix so I could get it out of where it was and home. A pile of replaced parts.

Got the Diesel running again. I installed a new gauge and she has excellent oil pressure. I went to move it and found the clutch brake was not working. The stud/ bolt had broken off in the housing. Had a time getting the old piece out. I had to drill it out and remove it in pieces. Looked like it had been ready to break for a long time. I V- ground the stud end and sacrificed an old plow bolt we had in the bin that was 3/4-10 and welded it back together. I had a die here to run over the threads and clean them up. Never Seize is my friend. Photo of it back together. Yesterday I put new bellows seals in the Power Steering unit. It sure needed them. Getting a box of new parts is almost like Christmas if it was not for the $$$. They say you can't take it with you. May just as well spend it on an old Cat. I've had a glass bead cabinet for about 30 plus years. One of the best investments I ever made as it sure makes cleaning up old rusty threads a lot easier. The left steering clutch lever was loose and the bushing was beat right out of it. Had to put it in the shop press to get it apart. I re-bushed it. Enjoy the photos. Dandy Dave!

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

Started it yesterday and ran back and forth for a while. It starts easy and runs well. No smoke and it runs clean. The power steering has come alive and works like a dream. I can hold back both levers with one hand. Photo of the oil pressure after running for an hour or so. Also, A new shifter boot installed.

Floor plates are in. Tapped out all the holes. Had to burn out an old broken tap that someone broke off in one of the holes and remove several other broken off bolts. All the holes have new bolts. I've worked on my share of these old cats in the past. Never seem to see one that has all it's floor bolts. Usually some are broken off or the holes are rusted and the bolts won't go all the way down. How many have you seen with all it's floor bolts?
