Gauge Cluster Repair/Assembly
This is the speedometer. The only difference between the speedometer and the tachometer is that the speedometer has the odometer and trip meter. The odometer and trip meter are housed in the gray assembly shown in the lower right of this picture. They are powered by the worm gear, center left.
Everything was disassembled and cleaned. Hoppies lubricant was used during reassembly.
The pointer is pushed onto a pin while turning counter clockwise. When it hits 0 you stop turning. It is press fit only. No threads, no glue. I chose not to zero out the odometer.
The small gauges are mounted to stamped brackets, two gauges on each. This one holds the temperature gauge on the top and the oil pressure gauge on the bottom. Unfortunately, this bracket had been modified and the temperature gauge won't fit. I need to fix the large hole on the top.
I traced out the outline of the hole onto sheet metal then trimmed it to fit.
Here it is clamped into position.
I positioned a copper bar on the back side then welded the plug using a series of tack welds. The copper bar dissipates heat so fast that it doesn't melt. It holds the molten puddle until it solidifies.
The tack welds were ground smooth.
Then I cut the correct hole using a Dremmel.
Here is the bracket with both gauges installed.
This is the mechanism for the oil pressure gauge. It's mechanical only, not electric.
The gauges have been cleaned, lubricated and mounted to their bracket.
The brackets and gauges are mounted to the backside of the dash cluster.
Here's the dash cluster before we started the rebuild. I media blasted and painted the housing, buffed and polished all the original plastic lenses, repaired the tachometer, replaced all the small gauges with 1963 gauges, welded a mounting bracket for the temperature gauge, cleaned and lubricated all the mechanical components, purchased new switches then I reassembled everything. So, how did it turn out?
I think it turned out pretty darn good. Click on the photo for a closeup.
Earlier today I posted information about the tachometer. If you didn't see it be sure to check it out.
Thanks for watching.
