Need a new tow bar and a trip to Xtreme too

Well, I took the coach to Cummins and they were putting it on the Dyno.  OOPs we backed it up too far and punched a hole in the brick wall with your tow bar.  The sad thing is that tow bar was purchased Aug 5th brand new.  Oh well, I will get another brand new one on Cummins and a trip to Xtreme to touch up the paint.

I heard that dyno's are hard on driving tires as they heat them up too much.
Crazy how others can mess up our coaches.

I agree with Barry.
I don't think I'd want to even  put my little 8.3 on a dyno, way too much stress. Bulkhead comes to mind...Chained up full throttle! quick edit add a little wheel hop to that too...

been on dyno's with over-the-road tractors not the same as pulling 50 tons up a grade.

Dyno gradually increases resistance until max power is produced, probably easier on coach than foot to the
floor on a hill and losing speed. Short time on rollers, will not heat up tires any more than ordinary driving.

When Cummins rebuilt my ISM 450 in July they put it on the dyno for a break in program for that engine.  Took about 1/2 hour at a wide range of power and rpm settings evemtually to full power for a short time.  All the while they were monitoring everything on computers.

Seems to have worked OK.  I just passed 50 hrs on the engine, purrs like a kitten, runs great.

Did ok on the Dyno but we changed out the thermostat and intake sensor. 

It is just scratches on the coach but need a new tow bar.

Dyno "driving" does not have outside air moving over tires and radiator, so often fans are positioned trying to keep tires cool, but as I understand it the roller and a tires get way too hot on a dyno.  It basically stresses systems to max and should only be done for a good reason if ever.

Another thing we see at Cummins is they want to steam clean the engine before working on it, even though engine may not be dirty.  Hot steam may do some damage by forcing water into places that have never seen high water pressure.
