Heat and Oil: Sifting the "data"
Trying to undertand what happens to air cooled tractors looks like building a case of circumstantial evidence. Here's a self dialog. Chime in people, In no particular order. It is said...
A. Oil breakdown is around 225F.AA. What is oil breakdown? B. At around 300F sludge forms.BB.Not found here ,2 teardowns 300F. C. At viscosity breakdown oil pressure drops dramatically CC. Not found here,always 35-40PSI hawkeye. D.Beede oil gauge goes to 320F Others too.DD.Gauge engineers know something. E.Kohler not worried below 300F . EE why? F.Engineering table (SAE related 1999) category "flash,"defined oil bcomes vapor and ignites. Table 10W-30 lowest flash by mfg 390F. FF.Doomsday. G.Fuel dragster crew "worried" at 340F. GG. Armageddon. H.Pan temp
230F is tops HH. Then oil is at about 210F? I.Recommended oil temp by mfgrs Kawasaki 210F BMW bike 225F Harley 240F Suzuki 248F Vespa 195F Intek silence II Hmmmmm.
Reread "Hot rides" above. Don't die with a secret, people. Let' hear it. Motoman
