Touch Control hydraulic pump o ring questions

Thanks John, so is it something that I can do with a propane torch with the proper solder, or will it require more than that?

robably more if Brash recommended going to a HVAC person.......

Hmmmm. Well perhaps it will be easier to find a used one.

Anyone know what a used one might run me, or have one to sell me?

Thanks!

HVAC = Heating, Ventilating, Air Conditioning in Ohio.

That is what it always was to me too. acronymfinder.com lists it as most common along with the other and also with "High Voltage Alternating Current" A few more are even more obscure ones are in acronymattic.com.

It will require more concentrated heat than you can get from a propane torch.

If you buy a replacement... send me the bad one. I have one that some nitwit tried to braze. Cleaning the brass off so it can be properly silver soldered will be difficult. This came with a "Cub in a box".

As I continue with this project a friend suggested getting MAPP gas with Oxygen at the hardware store. I guess it comes in cylinders similar to propane, but you need both. A set costs somewhere around $50.

Apparently this generates the proper high heat to silver solder this correctly.

Then I started thinking about a much more cost effective solution. JB Weld.

Anyone have any opinions as to why or why not to use it?

I do understand the premise of doing it right the first time, but right now money is very tight in our household. I could spend the 50 bucks, but spending 5 right now is very appealing!

Here's a picture of the offending manifold tube and previous "fix":



Well, I can't figure out how to get the pic to load, if you have any hints, feel free to let me know. I tried several different things several times.

Jeremy, you need to go one step further on your picture to get it to post. If you click on the picture at your bottom link, it will open up. You need to copy and paste that address between the image brackets. One thing to remember is that for an image tag to work, the address between the tags must end with a file extension such as jpg or gif.




As far as using JB weld - I don't think it will hold up in this application. If money is tight, I'd suggest taking the line assembly to someone local who does heating and ventilation work. Odds are they will silver solder it for you for less than what a tube of JB weld costs.

Jeremy:

I apologize for using the acronym, HVAC---should have spelled out Heating, Ventilation, and Air Conditioning.

I had previously posted a hydraulic fluid leak (my '49 Cub) on the forum and responses were to check to see if one of the tubes going into the manifold had come undone. If so, have it silver soldered.

I substitute teach at a nearby Technical Center and one of the vocations taught is HVAC. So, I asked one of the instructors if he would silver solder the tube/manifold for me. He used an acetylene torch for the heat source and silver solder. When hot, the joint "sucks" the solder into the joint not unlike when a plumber uses solder for joints on copper tubing.

The procedure took less than five minutes. Hope this helps.

Looks like it may have been brazed already, tho I have seen some silver solder alloys that have a golden color.

I doubt the JB would hold long, if at all.

You could probably take it by a air conditioning/refrigeration repair shop, or even a radiator repair shop. Either should have the proper equipment to fix it right. Anybody that works on air conditoners or refrigeration equipment, would more than likely have the proper equipment. And they probably wouldn't charge much to do so either. A few welding shops will occasional silver solder. Just some ideas to try.

Well, I guess I will take a drive tomorrow and see who I can find to help me out. I will check out the yellow pages tonight and hopefully have good news to post tomorrow.

Thanks guys!

Bigdog, that's just the explaination I needed. Just to prove I understand, here's a picture from 2 weeks ago. My daughter is pointing at the cub thinking something along the lines of "here we go again"

She loves driving the tractor! Almost as much as I love working on it!

Jeremy, Hope you get the tube silver soldered it will fix it. Mine had a crack in the same place and a neighbor that has a machine shop fixed it for free, took about 45 seconds!

BigDog I think we need a Kid's and Cub's album in the phto page to post all these great photos....Lildog there might be a contest lurking in there somewhere Something to ponder.

[Bigdog]

Kodiak - I created a Kids & Cubs album on the photo host site. It is in the City and Rural Life section. Now we need to start filling it up!

[Kodiak]

Thanks BigDog,
I know I have some and so does Cowboy as well as Jeremy!
Ok guys let's get those pictures in that album
