Technical Support / Re: C13 motor

Fred,

Yes, it is a federal violation of The Clean Air Act (likely a state violation too) to remove or disable any pollution control device on your Cat engine.

The non-regen ACERT used a catalytic muffler (DOC), so technically, replacing the muffler with a non-catalytic muffler would be a violation. California owners are experiencing this with their new inspection regulations.

Here’s an old Caterpillar YouTube video ‘showcasing’ the pre-regen ACERT technology (there are other videos out there).

Keith,

What’s going on with your C13? What kind of head work are they having to do?

Just curious… is it illegal to delete the emissions stuff off the C13?

Fred
We have the 07 C13.  It is currently in at CAT for head work.  Ours is not the regen going by the serial number.  I do thing ours is a left over 2006.  Still the CAT guy took one look and knew. I understand from talking to the mechanic here that there is now a fix.

Sirs:
  I have the same concerns as the OP.  I have looked several times over the last couple years for Shell's Gadus U1000-2 or S2 non-melting clay based grease.  Everything I've read says it's been discontinued unless you want a 39 lb. pail.  Checked out the Meritor product mentioned above, but was concerned about the " formulated for drum brakes" while our's are discs and it's specifically for the calipers.  Is the Meritor grease OK?

Phillips 66 has a bentonite based high temp grease called Bentone #2.  Wurth has their SIG 3000 super impact clay based Synthetic good for temps as high as 545 degrees F.  Which is higher than the Shell Gadus.  And you can buy these in a 14 oz. tube.  None of the greases I've looked at mentioned the 0-616A or 0-645 standards.

Has anyone tried any of these? 

A few years ago I took my "new to me" coach to the truck shop here in town and they wanted to use the standard red grease.  I told them not to bother.

Would like to hear what others with these older coaches w/ Meritor disc brakes have been using.

Thanks so much,
Mike Sulley

Update:  Fixed Propane leak.  Threads on main brass connection to the storage bottle needed some cleaning up to allow full make-up on face seal.  Now have propane to the stove top.

Technical Support / Propane sensor and propane leak

« Last post by Mike Sulley on July 13, 2025, 08:14:38 PM »

Does anyone with an older ( 2000 ish) coach remember how they changed over from a 4 wire propane detector to a 2 wire?  From what I have read, the requirement for the 4 wire w/ shut-off solenoid was no longer required in the early 2000's and has become hard to find.  My 2017 dated detector died recently and I could not access propane.  So I replaced the solenoid with a 3" brass nipple and attempted to wire in a 2 wire detector which are widely available.

My 2001 Marquis had a red, a black, and an orange wire (with 12 volts).  The original 4 wire detector had a red, a black, and 2 white wires.  One of the white wires on the original detector was connected to the two red wires. The two black wires were paired.  And the orange wire (w/ 12 volts). would have been paired with the other white wire on the original 4 wire detector.  Wish I had taken a picture before I disconnected, but I didn't-lesson learned.  Don't know if the two white wires on the original detector are the same.

So I wired the 2 wire detector ( w/ only a red and a black wire) as follows:  red to red and the orange( w/ 12v) to the black wire.

When I originally connected the 2 wire detector the green light was blinking.  When I pressed the TEST button, the red lights and alarm came on.  Now the green light is solid green and no longer flashing.  Is this how it should be?
 
New problem:  I just turned on the propane bottle in order to light the stove and I have a significant leak in either one of the two pressure regulators or between the two regulators.  Not sure which yet.  I have a small regulator stacked above a larger one.  I believe it's a higher pressure regulator dropping pressure to the larger lower pressure regulator.  Are these two regulators made as a unit or are they made individually?  I did notice that the connection between the two was loose and attempted to tighten it.  I will investigate further.  As a former pipe fitter in a commercial gas field, I tape and dope all threads, and bury the threads when making it up.  So I know it wasn't my connections.  I would not think that a diaphragm would suddenly tear but who knows, they are 24 years old.

Any suggestions on where to purchase a new propane regulator set would be appreciated.  Also any suggestions on my wiring issue would be welcomed.

Thank you for your help.
Respectfully,
MIke Sulley

On our 2002 Marquis the dash A/C was bad.  The drier went bad and blew desicant beads throughout the system.  The high pressure valve was blocked completely.  We took a chance on the hoses and got lucky with no leaks as the shop would have had to replace both lines.  It’s just not cost effective to find a leak along the rails somewhere.  The high pressure valve was located near the base of the windshield behind the front cap and someone very skinny has to wiggle up in there.
Good luck

My 2002 Marquis has a slow leak in the lines that can be remedied by recharging the AC every three years or so.

Hello Carl, I was afraid I would get an answer like that. I’m going to check in the basement area to see if I can find them , but accessing the whole length probably going to be impossible. Thanks for your reply.
