Saulsbury Rescue Truck Problems
We have a Saulsbury Rescue Truck that is approx 3 years old. The PTO that runs the generator shelled a week ago and blew parts down in the transmission that is warrantied for 5 years. The whole thing could run as much as $10,000 dollars to repair. The PTO was a Muncie. Has anyone else had this kind of problem with Saulsbury Trucks.

Why do you think it is a Saulsbury problem? Was it installed improperly or was the driveline angle too severe. It just might be a Muncie problem. What is the required horespower of the generator and what was the PTO rated for? If memory serves me correctly if you go above 25 KW you should use an 8-bolt PTO opening. It will be tough to pin-point an exact cause but do not forget to look at all the possiblities.

How often do you use your PTO. Most PTO's need to be inspected for bearing wear and blacklash every 40 - 60 hours of operation. If it blew apart several things could have happened. What was the engine rpm when the PTO was engage. Is it a Hot shift style. The condition you describe indicates that the PTO was Shock loaded. Higher RPM engagement with a full load on the Genset. Even at a lower RPM a heavily loaded gen set requires huge amounts of torque to start turning. You may have done this many times before with out a problem. Still doesn't mean its the right way.
There are many questions outstanding. Is the PTO externally or internally lubricated. Pressure lubed or spray lubed. If the unit ran for 3 years with out a issue something else happened. Cover the bases prior to slamming the manufacturer. You will also probably note that the unit is a 10 bolt mount on an Allison Transmission.

I'd agree with the previous two posts. We have a saulsbury box on it's second chassis! Could be something loosened up in the transfer case where nobody would catch it.These kind of things can be kind of hard to pin down depending on the extent of the damage.I'd say if it's gone two years with no problems, it's not a manufacturing problem.
