Come-a-longs, smoke wrench, gantry would all be helpful too.

Rather than dig a pit and drive the machine over it, I lay 2 8x8 timbers in front of each track and drive the machine up on them. Plenty stable and enough room to crawl under and do maintenance.

I have had hard lines with a fracture braised with good success. If the line is not seriously mangled, a crack is an easy fix.

Good luck!

Assuming your 450b is wired like my 450c, (we all know what assume means), you can use 12 volt batteries, wired in parallel, or 1 battery. The batteries wired in parallel give you more current to help starting in cold weather. On my machine, the batteries are wired with separate grounds from the neg...

Umbrella seal in the injector pump could be leaking.

Well Done!

Down the road, when you get the machine working, you will want to keep the backhoe attachment off unless you actually need it. The machine is very tail heavy with the hoe and it is much easier to maneuver without a 10 foot tail following it around. The front bucket will dig and grade much better too...

Is there a grease fitting under the square head bolt?

I had a small crack develop in the hard line coming from the hydraulic cooler. Had it brazed with good success. No leaks for 5 years since the repair was done.
If it is mechanical damage, not corrosion where the line is paper thin, this might be an option.

One other thought, you probably want to replace the recoil spring (death spring) and it's associated end caps as well given that everything else is pretty much shot. You will need the special high strength spring compressor bolt to install the spring.

Be safe

Hello: I have a 450C track loader with the same back hoe attachment. With the back hoe on the machine is VERY tail heavy. I would think it would be even worse on a 350. You might be better off finding the next size smaller back hoe attachment. "B town" is right about extending the hydraulic line out...

The 450C is a very good machine but I would pass on that one. Keep looking, they are out there but good ones are tough to find. If any two of the big three (engine, transmission, track system) are good and the machine is not otherwise beat, it is a candidate.

I replaced the undercarriage on my 450C much as JWB Contracting suggests except I purchased chains with pads attached and in order to remove the original chains, I collapsed the tensioner using the bucket and pulled the track loop off intact. Beat the master pin in with a sledge hammer. Good luck, b...

Happy to help, good luck, be safe.
