RE: Oil Temp???
ORIGINAL: mikehess43
On my 2007 Ultra I had the dealer install a Premium Oil Cooler Kit (P/N 26155-07). It has a thermostat that opened at185°F. He also installed two oil temperature gauges. One in the Bat Wing (P/Ns 75265-04 & 26133-07) and one in the oil dipstick that reads out both oil temp and level (P/N 63046-07).The bat wing gauge has never gone over 115F even though I did 300 miles at 80 mph with temps running 105F--the dipstick managed to read 231F. The dealer checked it all out and everything is working according to spec--the dealer checked with Harley Australia who then checked with Milwaukee who said that is the way it is....because the batwing gauge sensor is on the return cool side of oil cooler. A stupid design.
So the dealer switched the hoses around and now the sensor is on the engine hot side of the cooler...but its just turned winter here and on my first 150 mile ride the engine never got hot enough to open the thermostat. The dipstick only got up to 190F.
Bottom line, buy the harley extended warranty rather than the gauge....the cooler works but only when you are moving....

Also, the 26155-07 oil cooler sender should be tied into the intake, not the return hose. I have my sender in the pan, using the Allen plug next to the standard drain plug. You can adapt the HD sender using a 3/8"M-1/8"F brass adapter, available at most auto-parts stores.
