Guys,
I don't hear the clutch fan roaring. Even with the other clutch fan I heard no roar. I did insulate the cock pit area well. I tested the engine today using the Flow Kooler thermostat and here is what I found.
The engine ran great (as it has been)
WUD engine temp ---------- 196°
Harbor freight IR ------------ 201° (Thermostat housing)
Dash Gauge -------------------1st 1/4 (OEM Sender)
Stewart Warner Gauge ------235°
( Digi -----------------------------Above 200° )
* The Digi can be adjusted and has no relevance at this time.
I am thinking the engine is running fine and the Stewart Warner Gauge is not accurate.
ALSO: I am running 3 temp sensors on one Stewart Warner gauge via a switch to each sensor. Engine temp/Trans temp/Final Drive temp. It may be causing an electrical problem by how I have it wired.
The radiator is recording temp at the 180° to 195° range at the top coming out of the engine and 176° at the bottom going back to the engine.
I hope this is enough info for an expert (someone who is more experienced then I with this machine) to look at and confirm that the engine appears to be fine and it is a guage problem?
Thanks guys, take care,
Tom K.
