How to get under Bus without air?

oldmansax · January 11, 2018, 04:42:39 PM

Scott I am so glad to hear it!!!! I've been thinking about you all day..

I'll make one more suggestion: If you are going to set around until Monday before you move again, I would pump the brakes to release as much pressure as I could on that tank. No need of it being under pressure unless you need it. That said, I have an air compressor tank that has a crack in the bottom. I JB welded it 2 years ago and it's just starting to leak a little now. That patch on your tank may last until you sell the bus or it may blow off before I finish typing.

Help it all you can!!!

Thanks guys. Yeah bleeding off all the air is a good idea. Loooking forward to getting the new tank in and all of this behind us. Baby arrives in 3 weeks so we need our ducks lined up.

Good news! Just like I thought, it was leaking for a long time and just opened up more with the cold. Don't forget to thank JB Weld. Do you remember the episode on Seinfeld when Kramer was out test driving a car with a salesman, and the car was low on gas but they decided to keep on going? They ran out of gas eventually, but they had fun up until that point. I suspect that tank repair will get you further than Kramer.

That is indeed great news I have been following this thread with interest but didn't want to share my story. I patched the intercooler on my coach with JB Weld (it was a vertical crack in the tank about 12" long) and it blew out at the top of my driveway. Maximum boost on our rig (C10 Cat) is about 25 lbs. I figured it was a good chance of holding I've done lots of other stop gap repairs with JB Weld and had good luck. Ended up replacing the whole intercooler. The right thing to do.

Also glad to hear it, been following it. Crazy a small crack caused all that.

All the best!

So if it is a boy .... Tank R. Bennett?

When they install the new tank, make sure it seats properly at mounting tabs to body. Shim them if necessary, so you don't have a repeat failure.

Yeah, there's something dicey about that mounting arrangement -- something out of line, bent, etc. to put that kind of bending stress on the mounting bracket. That bracket and its weld should be hanging there when the rest of the tank has rusted away and has fallen on the garage floor as orange powder.

Is the tank hanging by the two mounting tabs or is there another mount somewhere else on the tank?

If it's just mounted by the top two tabs, then wouldn't there be a tendency for road vibrations, etc. to put stress on the welds between the tabs and the tanks? If there is no additional mounting, then maybe one could be fabricated to help in the form of a strap or something?

Reason I mention this is a similar thing happened to my Yanmar Diesel running my tractor when the fuel filter case cracked where it mounted. Yanmar had re-purposed the engine from a skid steer application to the tractor application and it was running at a different RPM in the tractor. This caused a different frequency for vibrations, and they discovered that another mounting point had to be added to this and a few other accessory mounts. When the dealer sent me the replacement it had a third mounting hole which was not on the original.

Scott & Heather · January 14, 2018, 09:07:53 AM

Well, after spending some time cleaning the hole and patching it using a mirror to view it, I realized that this was a rusted hole. Not a stress hole. Somehow it rusted at that point maybe moist mud was building up on there over the years and it corroded a hole right there. So I don't have to worry about it being a stress crack. The new tank just arrived so tomorrow morning she goes into the shop and the tank gets swapped out for a brand new one. I'll inspect and take photos of the old one.
