On my 03 chassis doing service at Prevost Mira Loma CA they had to replace the fan clutch. Mechanic said the fan was most of the way inside the shroud and was too close to the radiator, He replaced the 3 drive belts with shorter ones and said the fan should be about half inside and half outside the shroud. Hope this helps….

Thank you Brant, I checked them out and going to order 3 for the coach. For the engine, genny and inside. They are exactly what I was looking for…..

I installed it on my last (SOB) coach with a Detroit 60 with a 2003 chassis. It made a big difference from a start. Before install it acted like I was dragging the world, after install it would jump off the line. Did not notice if the oil stayed cleaner but got about 3/4 to 1 MPG better. I lived where I needed an dyno emission test every year so I ordered the extension for easier install and removal for test. I forgot one year to remove it and the test was STILL super clean. So I left it in from then on..

You can’t truly zero out a coach, that would be call a new coach. However, you can repair/replace the critical components. Air bags are likely the first step along with all the leaking air connections and valves. Belts, oil, filters, radiator fluid, generator belts and fluids, mini air bags if they are used for ebgine belt tightening and generator sound isolation. The brakes, shocks, bushings, tie rods, and much more, all need to be inspected and a determination made about replacement or time to replacement. We have a level 3 service done at Prevost annually when possible and they check around the underside to see what else might be an issue. My next visit will include having the engine air compressor replaced and at least a couple of Norgren valves.

The Lifeline manual lists the following charge voltages:

• Absorption: 14.3VDC @ 77F. Double the voltage for a 24 volt system.
• Float: 13.3 @ 77F. Double the voltage for a 24 volt system.

Yes do as Don says,I did the same, the filler cap the rubber is most likely shot

On my coleman you can only go 4 degrees at a time. If you try to go more than the 4 degrees it tries to turn on the gas heat. I don’t have gas heat so when it is cold I just move the setting by the 4 degrees.

Everyones has a plan til they get punched in the mouth by a bureaucrat.

Ahh. I see. I am just not familiar with how Liberty did theirs. Mine is all automatic with two auto-transfer switches handling Shore-Generator-Inverter.

This switch is in your cabin, so there has to be a contactor/solenoid handling the high amperage somewhere. The one for your generator is weak and opening or you have a bad connection on the low voltage side. That would be my guess.

I also need to plug the oil lubrication line, will do that tomorrow.

[Dave]

looking at drawings it looks like the oil comes from that fabric hose from top of motor to tee at rear of compressor then from tee at compressor to stainless braided line to rear of 50DN oils rear then small brass solid tubing to front of 50DN oils front bearing, then 1 inch oil line at the bottom of 50DN then oil returns to oil pan, then vents at the top of 50DN to front of gear box next to auto tenisioner.

OK here is what happened: I was unsure about powering the field wire unfused so i put an inline 3 amp fuse in between the battery and th field terminal on the alternator. As soon as I touched the +12VDC the fuse blew. Was I wrong to be safe and fuse it? What happens inside the alternator to cause this?

Update: It looks like the field stud is shorted to ground, What would cause this?

[Dave]

Tom, excuse my immediate reaction being a problem with semantics, or a seller that is clueless.

If the coach has OTR (over the road air) as you look at the engine from the rear you are going to see low and to the right a large belt driven compressor. No compressor, no OTR.

When we discuss driver’s air it is often in the context of it being the only Prevost installed A/C and it is powered by a smaller compressor usually located on the LH side of the engine bay. But my OTR system does have driver’s air which has a separate temp control from the whole coach OTR temperature control.

As to house A/C systems different converters used a wide variety of systems including roof airs which are whole system units (evaporator and condenser combined) roof mounted. They are the type used on conventional motor homes. Other A/C units are Cruisairs and they are split units with the condensers in the bays or behind a bumper or both. Vantare also used a large A/C unit, located in a bay which had output equal to 2 roof or Cruisair units. Coleman was a manufacturer of those units which are like a miniature version of house units you see outside the home sitting on a slab.

Vantare did make coaches with OTR, but they also made coaches without the OTR systems. If there is no OTR it will have driver’s air, engine driven, plus other types of house A/C units which will be powered by shore power, generator or inverters.

I have seen open pavers installed in commercial areas then grass is allowed to grow over it. This provides a solid base for parking hidden under the grass.
