Detroit Diesel 71 - 92 series fans

Thanks for your input.
Because I'm a mechanical perfectionist, new upgraded hi output compressor will be going on with a AD2 air dryer filter & purge kit, also service the Luberfiner 750, but I'll take the cheaper initial route redo the blower seals, I'm sure you are 95% right on this.
I also found I have a disconnected air control idle valve on the governor, I need to replace with normal idle speed screw assembly.
Zero coolant in oil, truck had sat for 4 + years, filters were dated 2004, so one can only assume that it had run minimally in that time, the oil drained was uniform in consistency, so figures crossed here no coolant/oil issues.

 

So how much do you want for this

 

I could use governor assembly if yours has normal manual hi-speed idle adjustment, let me know. Thanks

 

I could use a spare governor assembly if yours has mech' hi speed idle adjustment

 

I have heard the same.
