No manual gauge in rear. Talked with Prevo Pass as well as Truck ECM, who rebuilds DDEC IV and both think it could be wiring/connector issue on the 900&901 data line (c1 & c2 output on the IV). Prevo indicated ok to drive, but without know the actual culprit I am hesitant to move from where I am at. This weekend I am going to continue to…

Up in Vermont. Trip here was fine with no issues. Been parked for about a week at current spot and when I went to move the bus, it started fine, will go in gear and drive, but I do not have any reading on the oil pressure, engine temp, boost, tac, or speedometer readings. On the DID oil temp states no data, Batt voltage is normal 14.1,…

Yes, I just add in a little at a time and watch the indicator as well as wait a few min and see the temp at the dash. I set the temp down to 55 and fan on high.

Every summer ( over the last 10 years) I end up adding 1/2 to 1 can and at $10 a can at Walmart, it has been easier to do this than find where the loss is coming from

Question for those living in mountain country. I just purchased property in Vermont and the area where I was planning to put in a pad to temporarily park the bus until I can get a bus barn built is fairly steep. I will have about a 150 ft drive up an approximately 11 degree slope (as indicated on my trucks inclinometer) which is just under a…

I like the idea of getting more margin for my steers given I am pushing the advertised limit. My thought was to possibly switch to 365 on steer and keep 315 on drive and tag, and use my 315 spare if ever needed for the steer to get me off the road. My hesitation at this point is my Marathon has custom fenders and I do not know if I have…

Question for those who have went from 315 to 365. I can understand the benefit of changing the steers because of heavy axel weight (mine currently sits at 18,500), what I am questioning is what is the benefit of changing the tags?

Alex

The last time I ordered you had to check the box that indicated the product would be used by a certified tech.

For those of us keeping our Cruisair systems going, Ability has R22 on sale this week 30lbs $449. No tax and free shipping. I purchased from them before and never had any issues. They even shipped to me in CA.

If you already inspected the rotors and calipers and ruled them out, another thing to check is bearing play. What does the tire wear pattern look like. That would be a tell tail sign of where to also start checking.

Alex

Thanks for the feedback, my intent is to keep moving by them as well. Just checking to see if anyone ever had any issues bypassing them. I figured the highway patrol has their eyes out for more serious things than a well maintained private coach pulling a trailer. Now I just need to find the right trailer. I looked at stackers, but decided…

The units will be marked. It is most likely R22

Question for those who pull enclosed trailers. I am looking to pick up a 20-22’ enclosed car trailer to transport my 69 Camaro from CA to VT. Will likely take the 40 across. What has been your experience with weigh stations. Do you stop or just pass them by

Thanks

Hello Rob,

I am not familiar with that vintage, but Are you sure your docking lights are on the Marathon side and not the Prevost side. On my 2001 H they are on the bus side. Did you check the Prevost web site to see if they still list your bus and associated schematics, and have you reached out to Marathon up in Oregon. They have always…

If you haven’t found a bypass switch yet, you can try dumping the air out of the air tank that feeds the Marathon installed air rams such as the bathroom door, bed lift, step slide, gen air bags (on my Coach) and push the door back. It may bleed off the pressure. I have had to do that in the past. My aux compressor and air tank is in the…

My issue is similar, was removing recent tire install to do brakes, and one inner lug was on so tight that it was binding on the rim snapped when removing it. Thought I was going to have to drill everything out and replace the stud, but with some carful heating up of the remaining lug at the wheel and with an extraction tool, I was able to…

Read more

Eric, did you end up replacing the stud yourself, or take it back to the shop. If you did the job, what did it take to remove and install new stud. I have a damaged stud on my 2001 H3-45 drive axel (with disk brakes) and need to fix it asap as we are getting ready to hit the road.

Thanks

Alex

Hi Art,

I am not a battery guy, so my question is to try to further understand your concern. Isn’t it better to have more capacity than needed for those occasions when you may need the extra available power such as running an ac unit.

Alex

Now that I am going to install TPMS, question goes out to those who have a Prevost installed system. Prevost offers two different internal TPMS. One mounts to the rim with a band, and the other uses BERU sensors. The one that mounts inside with a band is their earlier offering and seems to be a simpler installation than going with the…

The bus handles surprisingly well as long as you remember to NOT hit the brakes and accelerate to maintain control and gradually slow down. It does want to pull some to the side of the blowout, but it is controllable and a lot of vibration until you get slow enough. I am amazed that other than the body panel, there is no other damage with…

So just shy of our CA place, on our way back from the east coast, front steer tire blew. Was doing about 65 at the time. Luckily the interstate wasn’t busy. The Michelin tire is only 1.5 years old and has maybe 15K miles on it. Did not see anything on the road so I don’t think we ran over anything. Felt the rubber let loose, then the air…

I just got off the phone with Prevost Tech. ( Eric is a great source for help and information) and the bottom line is NO on the retrofit

Alex

I have been trying to get to the bottom of why my curb side steer tire continues to wear on the outer edge. In January of 24, I installed new Michelins and had Prevost inspect the entire suspension system and hubs, replaced my upper control arms and did a 3 axel alignment to fix the issue. Worked for the first 8K miles then started to see…

Trying to sort thru fact from fiction relating to 2001 era h3-45 upper control arms. I read on another site that that era upper control arm bushings are susceptible to early wear due to dropping the front low while trying to level out at parked sites. They further indicated that the 2004+ upper control arms are more robust and there is a way…

Looking for some advice on where to start my troubleshooting. Occasionally my speedometer on my 2001 H3-45 will stop working. Everything else remains normal ,with the exception of the cruise control which will not work when the speedo stops working. The bus will continue to drive normally. Sometimes it will happen when I first start up…
