Oil Temp Guage
The catalog states that for 07 and later models P/N 26133-07 needs to be purchased along with the Guage.
Do I need that if I intend to put the sensor in the oil pan?
When putting the sensor in the pan, what fittings do I need to purchase down at the HW store?

RE: Oil Temp Guage
No, you don't need the filter-adapter kit (26133-07). Just go buy a brass 3/8M-1/8F NPT adapter. I couldn't find it at Home Depot, Lowe's, or Auto Zone, but located one at Napa.
To anyone with an HD Premium oil oooler who prefers to use the HD method for mounting the sender, you also don't need the adapter kit. As the sender will be mounted on the tee included in the gauge kit, and that fitted on one of the cooler hoses. I can't imagine why anyone would want to mount it in that location, though.

RE: Oil Temp Guage
good question Bob. On the old 88" motor the Harley Gauge sensor mounts in the oil line, leaving the crankcase headed back into the motor. It measures the oil temp ENTERING the system after cooling in the pan. IF the new directions have it entering the motor after the cooler (I am NOT familiar with the setup and don't have a cooler) it would be measuring the same value I guess but that doesn't seem likely due to the very different points in the circulation pattern.
Like to hear why from someone who really knows.

Sender in front with filter adapter 26133-07:
Pros: None
Cons: Much harder to install requiring filter removal, tee and hoses add to clutter around oil filter, costs $56 (MSRP).
Sender in front using existing oil cooler lines from adapter/thermostat housing:
Pros: Fairly easy to install by cutting existing hose
Cons: Adds to clutter around oil filter, will not read oil temperature accurately if at all until cooler thermostat opens.
Sender in pan:
Pros: Very easy to install, inexpensive.
Cons: Adapter costs $2 from Napa
I have a cooler and there's enough clutter around the filter area, so I wouldn't want more. If I didn't have a cooler I certainly wouldn't want to add hoses and a tee in that area if it wasn't necessary. The sender in the pan doesn't get in the way of anything.

RE: Oil Temp Guage
I see. It's not a functional issue, but a clutter /asthetic issue. But then don't you have to remove the sender every time you drain the oil? Does the sender go in the drain plug hole?
BTW, an oilthermostat is never completly closed. When cold/closed, it passes about 10-15% of the oil through the cooler. That way, all of the oil warms up to the same temp at the same rate. Otherwise, whenever the thermostat opens you'de get a cold slug of thick oil into a warm motor. In the winter, I cover the cooler on my car with clear duct tape.

RE: Oil Temp Guage
Bob, there are actually two places you can mount. Usingthe T adapter you can mount in the return line between the transmission and engine. This is the conventional installation of HD original equipment type gauge. It is a bear to do and getting the brass T into the space provided , splicing the existing line and re clamping it without causing a leak is tedious and frustrating. My dealer said never again after re installing my attempt which lasted three months and about 5K miles then started sucking air, causing a false zero pressure reading.
The easier installation is in the casting plug in the oil pan, the one with the big allen head that is sometimes mistaken for a drain. It requires using a step down bushing readily available at most hardware stores. It is in thepan and takes the temp there, making it at least similar to the return line installation called for in the instructions for 06 and earlier installations. Hope that helps. The casting plug installation mimics the Wally's gauge installation which is nearly identical to the HD gauge except for the install point.
