Scenicruisin'..?
i am 900 miles away from the action and relying on descriptions. its cool as I have built trust with these guys.
the thermal guy was asking for RPM specs on the fan ... i dont know it (a weakness in my factory data on this bus AFTER the repower). belt/gear driven, i presume it would vary speed with engine RPM.. i do not think fan has a "clutch" (like we use on car fans) and he was just eyeballin' it over a short time/low engine RPM run (since radiator is out getting assessed). Nobody says its making "funny" noises/rickety tho.
those gear boxes were originally manfactured by Ohio Gear. Bus forum guys (specifically the folks with running/actually doing work on 4501's) advise the rebuild kit Ohio Gear sells is $1,500. I'll call next week and get the skinny from Ohio Gear.
new thermostat (170 degree setting) checks out fine. i'm speculating "radiator" (not rejecting enough heat from the engine coolant) system ... but oil temp is important (i am told) as some cylinder/piston cooling is done by the oil (we are looking at that).
post-rebuild compression check/injector performsnce is checking out ok but i gotta get there with my own eyes/ears. BUT .. if we gotta go back deep into the rebuild?
kevin as always brother . .. appreciate your insights.
