I guess this has been somewhat of a blessing. Close inspection of the fan hub shows wobble, and the bearings are noisy. I got the hub off and pushed the bearings out. Will replace them.
Also the fan drive belt has cracks in it.  I'll get this stuff ordered tomorrow.
I found a few other leaks in clamps in the system too. Will get all this buttoned up.
She may run like a scalded dog after this stuff is done. 😇😇

Cliff, let me know if I can get your manifold. I need to get this back together quickly. Have a thanksgiving trip planned. I have two numbers for you ending in 309 and 162.
Or call me. I think you have my number. Ends in 729.

 David.

Well, after checking fuses and connections, it started, although honestly, I don't think it was anything I did.

We made it to a rest area near Wichita and would not be able to make it to the RV park in Enid, OK before dark, so stopped at a rest area.

I shut down and immediately started back up, so thought all is good and shut down again.  Then 10 minutes later I wanted to move to a different spot in the rest area and no go.

I'm wondering if there is something going on with the starting sequence that takes place when the main switch is turned on, since once it starts all is good.

Any ideas, we need to get started tomorrow and go just 2 hours to our home for the winter.

Thanks

This manifold was replaced in 2006. It was a takeoff that I bought from a boneyard in Harlingen Texas.

I had a feeling the exhaust leak was an issue because I would get the smell of it in the coach while driving sometimes. My wife noticed it, also.

If the manifold has blown a section out it is not always just the gasket the manifolds with age  gets thin and blows out  I have the manifold if you need it.soak the nuts good some of the studs go into the water jacket you don't want those come out. When reinstalling the manifold sets on a ledge if not resting on the ledge they will break when you tighten the nuts lol BTDT with some of my help   

You were right, Clifford. I actually got all four nuts off without using heat. I pulled the manifold off and there was still a piece sticking on there. It is in the picture. How much do you want for your manifold?

Hello all,

Looking for suggestions on what to do here.

When we left SD on Monday, when I turned on the main power, ddec display and wait lights did not come up.  I turned the main off and tried again and it did come up, so we headed here to NE.  Now I can't get it to come up at all.  We are heading for OK today.

Looking for suggestions as to what could be going on.

Thanks

David

I found the leak. I have a blown gasket on the exhaust on the radiator side that is blowing like crazy when I pressure up the system. I'm gonna have to take the radiator out to get to this. Ugh.

Here are my home made air stops to pressure the system.

I am back home now. I set up a test system to air charge the turbo charger. When I put air to it I only got it up to about 10 pounds on the gauge. I can feel air coming out of the tailpipe which means it is bypassing through the turbo fan out the exhaust.  Is it supposed to be that way? Am I testing this correctly to try to find any leaks on the induction side?
