Static Strip

To dissipate static electricity that builds on the bus to ground. Rubber, like tires are an isolator, where as the “strip” helps to discharge and prevent a shock upon entering or leaving the bus. Yes, they have steel threads in them the static electricity travels thru to the ground. Scrubbing you feet across carpet during winter, you touch something, boom a shock. Carry a steel threaded strap and touch something after scrubbing feet- no shock since the strap with thread in it touch item before your skin does. The static gets grounded out before skin touch item surface

Good Morning Chuck – sorry to read your post and can only imagine your frustration.

I actually have been following this post closely, reading and re-reading hoping you have found the cause. By no means am I an expert, yet here are a few thoughts….

One thing that might help, that I don’t believe has been covered, is a detailed description of the vibration you feel.

Is it in the steering wheel, which I understand would indicate front tires, or seat which I understand would indicate rear tires, or do you feel it in both your steering wheel and seat? Can a passenger feel it while seated in the passenger seat?

Also, is the vibration ALWAYS present at a certain speed / RPM?

Perhaps try to duplicate the engine RPMs at a slower ground speed and see what happens. In other words, if when traveling at the “highway” speed when you feel the vibration and the RPM is say, 1450 RPMs, manually engage your transmission and drive at that same RPM, but at say 35mph and see if the vibration exists.

Definitely go back to Jo Sam and have them mechanically check each tire for run out. Yes….a tire can, after mounting and balancing change position on its wheel, creating imbalance.

I cannot find it now, but know for a fact a Technical Service Bulletin (perhaps incorrect name of document) addressing engine vibration that can be felt by placing shims under the motor mounts.

I have also read where bad wheel bearings can cause a vibration.

Perhaps get up to the highway vibration speed when it is occurring, then put the transmission in neutral and coast thereafter to a complete stop. If when placed in Neutral, the vibration disappears, that would indicate a driveline issue.

Perhaps have someone follow you and visually inspect EACH tire when you feel the vibration to see if a particular wheel / tie is hopping / bouncing or can be observed rolling in a non-vertical, wavy orientation.

The person observing could also ensure your bus is not dog-legging down the road.

Does the engine harmonic balancer appear ok?

Might Jo Sam or Prevost have any used & mounted 365s that you could swap out for a test drive?

Jon or Tom, If there are any Prevost Community plates left I would like to have one.

Thanks!

Jim

John, I’ll be wandering around Florida by car for most of December. I’ll give you a call when I head down and we can meet up!

Oh!

I think you may be referring to the Detroit Series 60 “Unitized Valve Adjusting Screw assembly”. The early Series 60 engines had a valve adjusting screw assembly that used a wire type clip to hold on the cap. This wire clip would sometimes fail, separate from the cap, and fall into the area under the valve cover. This was later replaced with the ‘new” style “Unitized Valve Adjusting Screw assembly” with a more positive retention method.

12 for the intake valves. 12 for the exhaust valves. 6 for the injectors.

Just my best guess. Sorry if I got it wrong. You may need to do some more internet searching.

I am using the FMCA Sprint/T-Mobile plan and pleased so far. Unlimited data, no throttling. The only issue I had was getting it activated, but FMCA tech support solved the problem. I no longer use my satellite system. Currently streaming with Amazon Firesticks and a Fire Cube. FWIW, I don’t recommend the FMCA Verizon plan if you use more than 25 GB per month.

Dan,

Doesn’t that coach have bus air and roof airs?

Does Petoskey RV Resort have a 10-year coach age limit?
If not, what is the best time of year to be up there (other than now…”new to us” coach is being Prepped over next month+)?

[Tim]

Have had a problem and never really used my Wrico 15 KW gen set and a couple months ago after changing Transfer switch and new Magnum Inverter ( What Texas Custom Coach, Pipecreek Tx. says was wrong) unit still ran for a bit,, 30 minutes to an hour and shut down with overheat. I finally figured out and what 2 other companies (The other Griffin Industries) didn’t it’s the gen set dropping power and no AC for cooling fans. . Wrico says probably bad regulator. I’ve got to pull it myself as I’m not spending more of these greenbacks for crappy work. Can’t get to back of gen set as slide doesn’t come out far enough.

[Tim]

Looks like the OTR ac will be removed in favor of roof top units shortly, also available will be four cruise air units that are in working order as I am starting my rehab of the old girl.

[Tim]

You can argue until the cows come home what side to put it on.

My experience from the old truck days was we never got a new truck with it on the inlet side.

Over 850 3406B motors in Pete’s and they were always on the down side.

Like they say, do what you want.

These work well.
