I took the gauges and oil cooler off the old JD F510 and transferred over to the new JD Z320m mower. It has a v twin Kawasaki 21.5 hp FR651V. Last summer I was consistently getting oil temps around 250F after a hour and a half mow in 80-90F temps. This was measured via the fill tube immediately after shutting off.
The old cooler which is a Hayden transmission cooler with 3/8" hose inlets. Has a self restricting orifice for cold oil bypass. I put in a bypass ball valve too. It's mounted on top of the air cooling intake screen on top the flywheel. I used some 1.25" foam backer rod and mounted that over the screen. Then cable tied the cooler to that. We will see how it holds up.
The gauges were pretty straight forward . Just needed a good mounting place visible when using. And rerouting, securing the wire.
Probably too big now as it has air forcibly draw trough it. The old mower it was just mounted in front and the F510 doesn't move very fast. But it did the job on it for 20+ years.
It all added 450 mL oil capacity. I used a bigger filter too. The two adapters, one for cooler and one for the gauge ports and the extra length of the new filter added about three inches total. But still plenty of room.
