1968 Case 580CK
Senior Member
As a part of the restoration of my 1968 580CK, I decided to attempt removal of the instrument cluster casing. There were alot of loose wires and exposed wires, and non-working gauges, plus it makes painting MUCH easier to have all this removed first.
Removal was pretty straight forward....two bolts on the side, and one up top. Then, all the wiring to the gauges had to be loosened, the diesel kill cable, and oil pressure line had to come off.

Here is the cluster removed:

I noticed that on the backside, you can see the stamped circle where another gauge can be mounted (between the existing oil pressure and water temp gauges, a spot right above the steering wheel). In this pic you can see the indent where the gauge could be placed:

To remove this "knock-out" hole, is it best to first drill a one inch hole which you can then use to pry the knock-out plug out?

For some reason, my 580 CK does not have a fuel gauge. It has an oil pressure and water temp., but no fuel gauge. So, I could knock out this plug and put the fuel gauge in its place.
The two small outer holes are for lights for the oil pressure and generator. There are also two small light holes about an inch higher up which are not shown in my CK manual. Are these lights for an optional set of flashing highway lights? There is also a hole beside the light switch on the bottom right which may be where a flasher switch was located.....anyone know if this was an option back in 1968?
