Good comeback.
Not often anyone can catch Jeff asleep, but this time you got him. Watch your six.

They do need bigger rims. The biggest advantage is the weight capacity at a lesser air pressure than the 315.
There is a slight disadvantage in that you need to put them on the tag axel as well so that if you have a tire problem you can use one of the 365 up front. Also they are not always available every where.
I have heard some say that Prevost had these tires made specifically for them.

The lawyers on here may wish to offer some insight, but it appears to me if the pit does not fail structurally (that’s a whole different can of worms) there is no more or less exposure because whether the work is over a pit or on a flat concrete floor the potential hasn’t changed.
Where someone’s potential for a liability ramps up significantly is if a personal injury is involved especially if it was caused by a lack of observing good safe practices (always uses supports for example) or deviating from the procedures and specifications available in the Prevost service and operator’s manuals.

I had a hole in my muffler on my 8V92 and it grew slow enough to where I did not notice the noise right away. When I did realize something was making noise and I found the hole and replaced the muffler it was like a new coach.
The noise may sound cool for a while, but when it went away I realized how annoying it was to me. I can only imagine how loud it sounded outside.

Gonna see what my 2 stroke sounds like straight when muffler goes. Ought to wake up some folks with jakes kicked in.

MemberJuly 4, 2014 at 9:50 am in reply to: vibration upon acceleration in 1987 prevost mirageA smart phone can sometimes be used to track down vibrations. Download one of the vibration analyzer apps, I use “FFT Vibration Analyzer” on my Android. This tool will give you a graph of vibration frequencies versus amplitude. Our tires rotate at approximately 500 rotations per minute at 60 mph, or 8 Hz. Assuming a sixth gear ratio of 0.639 and a final drive of 4.56, we can calculate the following approximate fundamental frequecies for tire, driveshaft, and engine vibrations at 60 mph:
Tire: 8 Hz
Drive Shaft: 8 (tire Hz) * 4.56 (final drive ratio) = 36 Hz
S60 Engine: 1450 (engine rpm) / 60 / 2 * 6 (number of cylinders) = 72 Hz
8V Engine: 1450 (engine rpm) / 60 * 8 (number of cylinders) = 190 Hz
Of course it’s not as simple as it sounds because each of the vibration sources will generate harmonics at multiples of their fundamental frequencies; however, the fundamental is the highest amplitude.
Jon, with his 1980’s rotary phone may be challenged in this area! LOL 🙂

Some manufacturers use delrin, nylatron, and even steel in place of the big soft rubber donuts used to isolate our shocks from their mounting perches. You might recall the current trend of frequency, displacement, and acceleration sensitive shocks. We all know that shocks are velocity sensitive. These other techniques are aimed at softening the shocks over some road inputs and stiffening them over other inputs. For instance, you might want a soft ride over cobblestone surfaces but a firmer ride over long duration disturbances, wavy asphalt, lane change manuevers, etc. I’ve always felt that the way to get both in a cheap shock is by using large and very compliant rubber donuts to attach the shocks. The large donuts deflect over the choppy low amplitude stuff softening the ride, but over large amplitude displacements the donuts quickly compress allowing the shock to provide most of the damping. Voila, a poor man’s frequency sensitive shock! 🙂

What Andre says is true.
On more than one occasion the selector switch for front or rear start is the issue. My concern is that it won’t start on either front or rear position so it might be something else is going on.
For what it is worth I’ll bet I have had half a dozen tell me their new batteries were wired correctly when their bus would not start after changing them. In fact the batteries were not wired correctly. But if your bus was starting and running and everything was normal after the battery change you can rule that out.
Did you check the ignition relay (solenoid) in the rear electric box?

Peter didnt hear back did find anything with the Hall tivoli on that circuit?

Hey speaking of the rally (we were ,werent we ?) Us folks from Titusville are going to be leaving the Ihop restaurant at rt 50 and rt95 at 9am in case anyone wants to caravan over to tampa with us . I have found that if you show up at the same time with a large group the folks at the campground are absolutely ecstatic to see you

Brian,
I replaced mine about 2 years ago. Dig out all the silcone from around the large pipe where it goes thru the floor and that will give you some wiggle room to work with. It is a pain to get everything lined up and reconnected but it can be done.

Rob,
Welcome to PC Rob, you found the right place for information and assistance.
I
had a 2000 CC and it was a good bus and had the CC glass dash and
famous DOS 3.1. I was fortunate and didn’t have any dash issues, but
did have to replace boards in the overhead for the bitch in the box
or called the synthesizer..As
others have pointed out, you can still get parts from Miles and if
you can hook up with Nick he could likely help you. The problem is
not parts, but where do you find someone to work on it. I doubt there
is anyone out there other than those two that can troubleshoot and
then repair your dash. The bus will still run if it goes blank, but
you’ll be without any information. The solution other than those
above is Silverleaf and that conversion is in the 12K range I
believe.The
CC guys will jump in here and correct me if there are places to have
the glass dash worked on. What you wouldn’t want to do is have
someone try to learn the repair on your wallet. -
Marathon uses Lifeline because——–they just like Tom!!! Trying to get a little laughter starting this morning,

Michael,
You haven’t identified your year or converter, that would help with questions. Sounds to me as though the relay is bad.
