SuperC Info and Discussions / Re: 2007 Seneca Duramax: Downpipe to Cat pipe joint repair

I've broken pipe #3 in the diagram and the flange from the front of the catalytic converter not pictured. Now we have broken the long pipe behind the cat. Seems like no matter how we add hangers to the exhaust, it's always under strain and breaks.

SuperC Info and Discussions / Kodiak 5500 cab A/C drain location

Last post by CrazyTed - July 29, 2020, 03:05:56 pm

We've been getting some water condensation dripping inside on the passenger floor with the cab A/C running. I looked outside for the A/C drain line but could not find one. Anybody have a location for the A/c drain under the hood for the 2008 Chevy Kodiak 5500? It's my 2009 Jayco Seneca RV. The pic is from the front of the A/C under the hood. You can see water dripping from the screws on the box.

Depending on where MH was/is stored. Look for rust. Some of the 35GS models had wrong rear springs. Some added air bags. Others added another leaf to rear springs. Beyond that they have fairly solid chassis.

FIrst off welcome...

Only issue I had with our 08 was the radiator. The lower driver's side tank has been known to leak due to a bad crimp on the tank. Look for any residual antifreeze in that area. The other item would be tires. Check the DOT code to see how old they are. Hopefully Ron will jump in since he is very knowledgeable when it comes to the mechanics of the KODIAK..

im new to the group but have been reading the posts for days, as well as new to the large diesel MH game. im looking at purchasing a used jayco 2007 seneca 35gs with 35000 miles on it. what do i need to look for when doing my pre purchase inspection? what are the glaring issues i need to be aware of while performing driving tests and gen tests. what is the proper startup procedure to check all the appliances and electrical equipment? basically want to know what im getting into possibly as well as what to look for onsite. any help will go leaps and bounds at inspection time. im a very well educated shade tree mechanic but not a veteran at this by any means. thanks again everyone.

I have a brand new item 3 in the drawing. I have no need for it.
Your fix looks good.

I have a 2007 Seneca on a 2006 C5500 chassis with a LBZ Duramax. I noticed exhaust smell in the cabin and traced it down to the joint between the turbo downpipe and catalytic converter exhaust pipe:

OEM replacement parts listed for about $500 before shipping

Here's what I did -
Parts purchased:
Walker 41646 flared exhaust pipe ($20 on Amazon)
Squirrelly 3" x 4" stainless flex exhaust pipe ($23 on Amazon)
Grand Rock v-band clamp GRVB-384G ($26 including shipping from xtremediesel.com)
Felpro 61287 catalytic converter gasket ($8 at NAPA)

Assembly:
Cut 1.75" off Walker piece:

Cut 5.5" off cracked end of exhaust pipe:

Weld-r-up and test fit to downpipe:

Reinstall and check clearance:

So, for about $75 in parts and a little of my time, I'm hoping the flex joint with relieve the stress and keep it from cracking. I should be no worse off than if I had implemented the oem parts except that I have extra money in my pocket for other things. I hope this helps someone else like this site has helped me! Your mileage may vary...

My research led me to believe the controller (located on the board inside the cabin on the control panel) needs a firmware upgrade. Supposedly, there is a bulletin #696 that outlines the problem and recommended upgrade. Any Cummins repair facility should be able to do it but the one near me won't take any interest. Until I get mine upgraded, I unplug the generator control panel in the cabin and the problem has stopped.

Use this link and check with JAYCO. We had full body paint so I don't know the answer directly.

SuperC Info and Discussions / 2007 Jayco Seneca 34ss exterior Graphics question

Last post by crhineberger1 - June 09, 2020, 03:55:42 pm

Does anyone know if the graphics all around the Seneca are painted on or are they stickers? I can tell the Seneca logo on the sides and the Jayco birds are stickers but not sure about the long sweeping red and brown graphics if they are painted on or really nice decals...

My white paint is I think the term is oxidizing and have seen some posts on youtube with Optimum Gelcoat Restorer and I think that process will fix the white areas. The sweeping graphics that are red and brown are still shinny and look good.

Any thoughts on what you all have done to revive the paint and stickers would be great!

Thanks!
