The Caterpillar 235C hydraulic excavator/front shovel was introduced in 1988 in the USA and Belgium. It replaced the Caterpillar 235B.

[edit] Features

The 235C has a 3306 engine producing 250 flywheel horsepower (FWHP). It comes standard with stronger track shoes, increased implement pressure, and a larger fuel tank.

The 235C was manufactured in the USA, with a 3WG or 5AF serial number prefix; and in Belgium, with a 2PG or 4DG prefix.

The 2PG has a larger boom to stick pin.

The 4DG and 3WG units have a heavy-duty carbody strong enough to be used as a front shovel, mass excavator, or material handler. It comes standard with larger boom cylinders and larger buckets. The 3WG has a counterweight of 17,000 pounds (7,650 kg) for trencher configuration.

[edit] Modifications

In 1988 Caterpillar modified swing performance, increased swing circuit pressure, and added a variable displacement swing pump, swing monitor, and a gear-type pilot pump, beginning with 5AF00267.

In 1989 Cat added larger bearings and a 245-type coupling in the pump drive, beginning with 2PG00535, 4DG00405, 3WG00149, and 5AF00687.

In 1990 a fuel level gauge was added to the Belgium units, beginning with 2PG00583. A Euro-cab was introduced, the heater and defroster were modified, sound level was reduced, the disconnect switch was relocated, and Cat added a polycarbonate skylight, a Bostrom Viking seat, parallel action windshield wipers, sliding rear and cab door windows, and radio and speaker mounts, beginning with 2PG00679 and 4DG00561.

Production of 235C ended in 1992; it was replaced by the Caterpillar 235D.

Based on data from the sales database of Ritchie Bros. Auctioneers, it is estimated that more than 3,700 Caterpillar 235C hydraulic excavators/front shovels have been produced.
