1911 Cadillac

For
Krown Restoration

This 1911 Model 30 Cadillac was purchased in boxes. The previous owner disassembled the car and restoration never proceeded.

This was the state of most of the components upon arrival at the shop. This is a cylinder with cylinder head and valves attached.

The cylinder walls had corroded significantly. Fortunately there was enough material that the walls could be spray welded and the machined down to original dimensions. This is the end result.

After spray welding, the cylinders were set up on a lathe and the O.D. of the walls were machined down to original dimensions.

Most of the original components were not suitable for use. This is a new water pump shaft machined out of low-carbon steel.

The original camshaft bearings and shaft had worn considerably. A new camshaft had to be made. Using a 1060 precision ground steel rod, a new shaft was cut and drilled for the tapered pins that hold the camshaft lobes.

The new camshaft being drilled. It was mounted on a mill with a horizontal turntable.

The original camshaft bearings were sleeved with silicon-bronze. The bearings were installed into the crank case and bored.

Test fitting the crank with plastic gauge to the main bearings to test tolerance afer boring.

New rollers were installed into the lifters. Modern roller bearings were used to reduce strain.

Test fitting the new lifters in the crankcase.

The camshaft timing gear had worn out of round. The center was machined out and a steel sleeve was pressed in. The gear was then drilled and reamed for a tapered pin.

The timing gears were repaired and re-installed into the crankcase. A new accessory drive gear was installed.

The water pump, oil pump and magneto restored and mounted to check drive shaft alignment.

New couplers and coupler keys were machined for the accessory drive.

Coupler keys were machined out of Delron plastic.

Despite the condition of the car, the transmission was in surprisingly good shape. It was disassembled and inspected for wear and cracks. New bearings were installed and an epoxy coating was applied to the inside of the case.

Transmission repainted and ready for install.

A new cork float was machined using the lathe and a tool-post grinder.

The water pump mounting face had broken in half. A new section was welded on. The pump was then mounted into the surface grinder and the mounting face was ground flush.

Oil pump restored.

New butterfly shaft machined for carburetor.

The original timing gears located on the bottom of the steering column were made out of pot metal. Over time these had crumbled to pieces. New cast bronze gears were purchased but the castings were in rough condition and had no holes for the control rods. New holes were drilled and splines were cut into the holes. The gears were then hand fitted for a proper mesh.

New timing control gear marked and ready to be drilled.
