Everyone with NJT Eagles. There are two of us Eagle 20 owners here in Michigan that I know of, and our radiator fans operate differently from each other, and wondered how everyone elses operated. Here's the deal. My buddy's fan has a switching assy. attatched to his fan motor that controls the hydralic fluid to the fan when the coolant temps. are below 180deg? and his fan speed is variable. So when idling, the fan runs really slow, and quiet. Mine on the other hand, appears to have NO switching assy. attached to the fan motor, and runs full speed all the time. I talked to Norris at Jefferson Truck, and he thought NJT was in the process of changing to a different fan motor about the same time they were phasing out the eagle 20s. Does anyone else have a one speed fan motor with no switching assy, or maybe mine has been removed for some reason. Anyone have any information reguarding this matter? Thanks.

The switch is actually a hydraulic porting device that fluctuates with temperature changes based on a set point bias. I would be very surprised if your unit does not have this device and maybe it is just sticking closed. Take that time to trace that hydraulic hoses and see if you find hoses going to a device that is attached to a coolant pipe on the engine.
Regarding the pumps, I heard also that they were changing to another better pump but I did not hear anything about changing the control system.
Lastly, When I bought my bus I noticed that NJ Transit shops had installed the wrong hydraulic filter on on this system and the pump was actually suffering excessive load trying to press the fluid through a filter that was 3 micron nominal. The book calls for 10 micron and it is just a matter of buying the different filter and spinning it on. Theory is that the wrong filter was what was really failing the pumps sooner than expected. |

You may want to post this or just join the NJT busnuts group
http://autos.groups.yahoo.com/group/NJTbusnuts/
It's a small cozy little group, the vast majority are MCI owners, but we'd love to welcome more Eagle owners. We even have a GMC owner (the bus was in the precursor to the NJT and we voted him in!).
best,
