Can it be done, SURE. But, you will be replacing: Shore power cord ATS Wiring from ATS to 120 VAC breaker box 120 VAC breaker box

Diesel Motorhome MPG-- Honest Answers Please
wolfe10 replied to luckydog1949's topic in Type A motorhomes
Ya, and you really have no idea in a lot of stations (and neither do most of the station employees), as many state: "Up To 20% Biodiesel" -
Diesel Motorhome MPG-- Honest Answers Please
wolfe10 replied to luckydog1949's topic in Type A motorhomes
Bill, I run as close to zero bio as I can find. Fewer BTU's in bio, so MPG suffers a little. Shorter shelf life, clogs filters, etc. -
Slowing down a couple of MPH will help MPG.

Diesel Motorhome MPG-- Honest Answers Please
wolfe10 replied to luckydog1949's topic in Type A motorhomes
According to retired Petroleum Engineer I work with, most fuel for all stations comes from the same limited number of refineries. Yes, additive packages can vary to some degree. But, absolutely, #1 diesel has fewer BTU's than #2 diesel. So if a station (any station that received fuel during the really cold months) still has #1 or a blend of #1 and #2 diesel, sure MPG will suffer. BUT, the difference in BTU's is only 2.5%. HOWEVER, the difference in Aerodynamic Drag between 70 Degree F air and 30 degree F air is 12%'. That is why most of us get the same MPG in the summer running the dash air as in the winter without it-- the factors offset each other. The Caterpillar Corp document below is a VERY good read for any DP owner, not just Caterpillar. http://forum.dieselrvclub.org/index.php/topic,6594.0.html -
ObedB, Correct. Lube just as this PacBrake document suggests: http://pacbrake.com/supplemental-brakes/fixed-orifice-exhaust-brakes/maintenance-2/ There were several vendors at the Pomona FMCA Convention with the PacBrake lube in stock-- sold a lot of it.

Yes, here is a link to the Workhorse/Bosch brake recall: http://www.rvbusiness.com/2010/01/workhorse-addresses-recall-for-bosch-brake-defect/ And, it was my understanding that most all the defective calipers had been replaced under warranty.

Walt, A very common issue with the Bosch hydraulic disk brakes (phenolic pistons absorbing moisture and expanding until they seize in the caliper bore)-- resulted in their major recall.

Don, Welcome to the FMCA Forum. Was not aware of a big issue/class action suit with the Bendix brakes. Could you provide us a link?

ktbaillif, Welcome to the FMCA Forum. Check U-joints for play. Check ride height-- that short drive shaft is particularly susceptible to out of spec angles. What suspension do you have-- Velvet ride or air? Check lug nuts-- make sure the wheels are properly torqued.
-
You need to verify that the "not towable" applies to dolly towing, not just to 4 wheels down towing. I would start with the service manager of a Honda dealership-- he is likely to be more knowledgeable than the kids auto manufacturers hire to handle "customer contacts".

Carluv, Welcome to the FMCA Forum. That is a puzzler. Either generator or shore power should provide exactly the same "power" to the battery/batteries (house for sure, perhaps chassis as well) through your converter, charger or inverter charger. Said another way, your charging device only knows that you supplied it with 120 VAC so should be no difference based on shore power vs generator. The first question is: Which battery bank, house or chassis powers the slide motor? The next step is to check voltage at the battery bank that provides power to the slide motor-- both at rest and when the motor is engaged. Something as simple as a loose terminal (metal SHRINKS as it gets colder) could cause too much voltage drop. The last test would be to check voltage at the slide motor terminals both at rest and when someone is engaging the slide motor. AND, a cold battery provides less power than does a warm one. Also, as Ray pointed out, seals are stiffer in cold weather. The combination of "all the above" may have done exactly what Ray suggested-- overload the resettable breaker.

Southwindtrails, Welcome to the FMCA Forum. I guess the best answer is that Caterpillar calls for the first valve adjustment around 30,000 miles in an RV application.

Replacing Wet Cell Batteries with AGM - One or All?
wolfe10 replied to gaylemarlowe's topic in Electrical
When replacing batteries always replace all batteries on a bank with the same (new) kind/technology. OR, that one old battery having one cell go bad can cause your converter or inverter charger to overcharge all the batteries in an attempt to turn that now 10 VDC battery (one dead cell on 12 VDC battery) to 13.2+ VDC. No average life for batteries-- depends on initial quality, how deeply and how often they are discharged, if they are equalized, water level kept up, etc. -
Be sure to put only ONE filter between the tank and lift pump. So fuel tank, primary filter/water separator with course filter (10-30 micron), lift pump, secondary fuel filter (fine element 2-5 micron depending on engine specs) then engine or injector pump.

Good job. Welcome back to the "way less sway" camp. A very easy thing to check visually and also easy to replace. Only tools are a pair of vice grips to keep the end link from turning and a wrench to remove the top and bottom nut. As long as you are on flat ground, no need for jacks, etc. You can lower and raise the sway bar with your little finger as long as the two wheels are on the same level. If the main bushings need to be replaced, be sure to lube them. The marine green, sticky grease works great.
-
Yup, they have been long-gone. So that sway bar is getting a "free ride"/not helping control sway. Replace them with Polyurethane bushings-- you will need all 8 of them.

Kurtden, I would talk with a Cummins tech or Cummins Corp to VERIFY that there is no special bleed procedure when changing coolant. Many engine DO have to have the thermostat housing bled when changing coolant. In fact many engines are set up with a line from thermostat housing to overflow reservoir for just this reason.

Towing A Jetta Sport Wagon
wolfe10 replied to jamestouchstone's topic in Toads-Towed Behind Motorhome
I have heard of vehicle with too little front end CASTER doing that. It was not recommended to tow early-model Subarus because of that. Push a grocery cart backwards at speed and find out what too little/reverse caster does for stability. -
We may be talking about two different things here: After-cooler, aka Inter-cooler, aka Charge Air Cooler (all the same thing) is an air to air heat exchanger that takes intake air from the turbo (up to 300 degrees F) and cools it down to close to ambient temperature before sending it the engine intake manifold. Yes, in marine applications, it can be water cooled. Never seen a water cooled one in an RV application. Many HD diesels have a built in OIL cooler that is cooled by circulating coolant. Wonder if that is what they are talking about??

ObedB, Racor makes a very wide range of size filters. Quite certain they have one that will work great as a primary fuel filter/water separator on your coach.

Dusty, With a DIGITAL VOLTMETER (a real necessity on any RV and they start under $20): With everything off: At the chassis batteries At the house batteries At the starter Fully charged is 12.7 VDC. 50% discharged is 12.2 VDC. If not fully charged, start by fully charging them. Same places with someone trying to start it. Begin at the chassis batteries. If they drop over .7 VDC while cranking have the batteries load tested. If all the above OK, then start checking connections from battery to starter. Don't forget the ground side.
-
As an RV professional will evaluate, an ATS has two "IN" circuits-- one from generator and one from shore power. Only ONE "OUT" which goes to the coach 120 VAC breaker box. You can only have one source of 120 VAC (because it is alternating current) at a time. The job of the ATS is to choose only ONE source and be able to switch between them.
-
Actually, with 6 VDC batteries, the HAVE to be in SERIES, as everything in your coach is 12 VDC. So: House positive to positive terminal of battery #1. Negative of battery #1 to positive of battery #2 and negative of battery #2 to house ground.
