I have a 59 4104 former Greyhound with VCH heating and McGRAW air conditioning. It has 5000 hrs on unit. Is it worth using? If so I need any information available on this unit. My bus manual only gives me a wiring diagram. Engine is a 4cyl diesel...does anyone know who manufactured it? Thank you very much. |

If it is the orgional factory air I believe it was probably manufactured by Continential. Some of the older forklifts used this motor and I believe parts are still available. I also have a "59" 4104. I felt the space would best be used by a generator. I will use the generator to power my roof top A/Cs going down the road. With the factory over the road A/C you will not have air when in a camp ground unless you run the pony motor. Space is at a premium in a 4104.

If it is a diesel I don't believe its original. The unit has been installed as a replacement |

The Greyhound PD4104's had a 4 cylinder diesel engine.And I am not quite sure who made the 4 cylinder diesel engines for the Greyhound A/C systems.
But this system was used by Greyhound and other bus companies that might have wanted to use the A/C system that Greyhound had.
I know that some of the other bus compaines that used the PD-4104,s used a Continental and others had a Waukesha engine.
If the A/C is working on your bus it will cool the bus very nice.
But if it needs repair and or a overhaul go to roof A/C units with a nice generator in it's place.
I know where there is a complete unit in a Greyhound PD-4104 that can be had for parts.
As for the AC maintenance manual it's a special supplement manual.
Check with Luke at US coach repair for a reprint.

My 1951 4104 had a gasoline engine. Continental, as I recall. There was a separate fuel tank for the genset. The filler was about 1/3 of the way back on the passsenger side. 25 gallons IIRC. I never heard of a diesel engine powered unit.

I have been using an original Greyhound 4104 A/C compressor for a shop air compressor for years. I have never bothered to find out who made it, but it looks like a Perkins. The only maintenance it gets is oil and filter changes. If I need something unique, I will have to investigate further. |

I have seen some of the old gas powered Continentals converted over to diesel. The plugs and distributor were exchanged with injectors and a Bosch distributor type pump.
They were really hard to start, particularly when it got cold out. But once started they used next to nothing in fuel and were still able to make enough HP to make the A/C cold.
