Re: Instrument gauge removal and light bullb replacement 42 Clipper

Everything is accessed from under the dash. Bulb sockets just pull out of the cluster and bulbs are changed then sockets pushed back in the holes. The instruments are mounted on plates screwed to the cluster case, two gauges per plate. The entire cluster is held by screws and can be removed as an assy after the wires are disconnected and temp gauge sensing bulb is disconnected and pulled thru the firewall. The speedometer mounting shares a screw with the cluster so take that into consideration. All of the screws thread thru holes in the dash directly into the pot metal chrome front . Depending on whether the speedo leg is on top or bottom the speedo may need to loosen to remove the cluster and if all the screws for speedo and cluster are removed the pot metal piece may fall and scratch the woodgrain. The woodgrained panel can also be removed in its entirety but a couple of screws holding it are a bit fussy and hard to reach. There are spacers and cushion material which can be hard to replace properly so the panel fits well again. Take note of any fabric anti squeak material on the cluster or speedo too. If you just need to get to gauges IMO it is just as easy to remove only the cluster part.
Oil, gas and ammeter gauges are electric and easy to remove from the plates. Just remove the nuts on the terminal and pull them out of the mounting plate. Watch out for and take note of positions of any insulating washers. Temp gauge will need the sensor bulb removed from the head and if it has been in place and not touched for a long time there is a good chance it has all but glued itself in. That removal is not a job you are going to enjoy. If you manage to get it out without damage celebrate the occasion because you are more fortunate than several others on the forum. Once the sensor is out and pulled into the interior there is a single large nut holding the gauge to the plate. Remove the nut and pull the entire gauge including cable and sensing bulb thru the hole and out of the plate.
Here is a photo of the rear of a 47 dash showing the cluster and speedo. I believe the construction and layout is identical to the 42 except for the ashtray area. There is a service letter article specific to 42 Clippers and how to alleviate some dash noise issues.https://www.packardinfo.com/xoops/html/downloads/SC/SL-VOL15NO23.pdf
