Caterpillar DW10 (1V) '1947–54

Now the 1V series DW10 was quite a different beast to its predecessors and for the first time featured a scraper of Caterpillar’s own design, the No 10.

It also had a new engine, the 115 horsepower Caterpillar D318 which had a larger bore and more torque than the D468 used previously.

Design-wise the machine was very different from earlier models as well.

Gone were all the clean curves replaced by a chunky, matter of fact looking machine with an exhaust pipe projecting through the hood.

A change was made to the transmission early in production to strengthen it against the increased loads imposed by the new engine.

The No 10 scraper, which was basically a Caterpillar No 70 towed scraper fitted with rear brakes, had a rating of 7 cubic yards struck and 9 cubic yards heaped and was all cable controlled by Caterpillar’s own No 21 double drum Power Control Unit (PCU).

Features of the No 10 scraper included its eccentric cantilever rear stub axles, not supported on their outside, which could be adjusted for odd sized tyres, and the curved cutting edge, similar in design to the LaPlant-Choate CW10, which the No 10 replaced.

A major revision to the scraper in 1952 saw the capacity increase to 8.7 yards struck and 11 yards heaped and the replacement of the adjustable rear axle with a straddle mounted type and a switch to a straight three-piece cutting edge.

The apron sheave tower was also opened up which allowed easier access to the apron cable for reeving.

These modifications were also applied across the entire range of Caterpillar’s towed scrapers as well.

Design of the No 10 Wagon remained unchanged.

The DW10 remained in production until 1954 when it was replaced by the slightly larger and more powerful DW15.
