Hornsby Mammoth being removed from its storage shed at Seven Hills Golf Course Pt. McNeil B.C. Machine was on display here for 20 years. August 4th, 2005, Cat 980 pulling.


Machine ready for loading. Required two 980 loaders to lift onto lowbed.


On route to Historical Construction Equipment Association Show August 4, 2005 in Wetaskiwin, A.B.


George's granddaughter admiring the old iron.


Crankshaft loaded length ways inside.


Hornsby upon arrival at Reynolds Alberta Museum at Wetaskiwin Alberta, where the HCEA show was part of the Alberta centennial celebration.


Machine being set on its display pad at the show August 4 2005.


Pat and Phil Scarborough from Grantham Lincolnshire England. They came over to the show and were amazed to see the Hornsby Mammoth on display there. They presently live only a few miles from where the machine was built and were planning a trip to Vancouver Island to see it. Boiler was cut out of the machine when it was in the bush at Apple Bay on Vancouver Island sometime after 1955.


A distant relative from Stockton California is Bill Grahams 1914 Holt, newly restored for the show.


The Hornsby's crank, clutch, and flywheel with 4 valve eccentrics. This assembly weighs 3500 lbs.


Main drive gear. Drives on one side only through a huge rear end with differential lock system. Condition of gears is like new. Rear end housing to the right.


Sprocket with steering clevis. Note winch drum top center with small spool on stearing shaft to allow cable to be run out through the front fair leads to pull the tractor forward. Track rollers mounted on 8 inch diameter hollow axel. Axel has 4 inch hole through the center. We couldn't imagine the existence of an 8x4 inch hollow tube with a 2 inch wall thickness in 1909.


Track rollers or wheels with upper track roller mounts. Lower tracks were buried in mud for over 50 years. Fortunately the dirt had rusted to the tracks preserving the metal. The lower castings are actually in better condition than many exposed to the weather.


Inside of track. Pins are 2 inch diameter by 17 inches long. On top of these were 5 inch oak pads. Note the holes where the lubrication galleries for the pins start. Far right is one remaining brass plug. A track lube consisted of removing, oiling, and replacing 160 plugs. The machine would also have to be moved to access the plugs. This was the worlds first fully sealed and lubricated track pin system.
