|  Comment on this model.
The Caterpillar 660 was a large three-axle scraper that was introduced in the early 1960s. It had a 54 cubic yard heaped capacity (41.3m³), and weighed over 52 tonnes empty.
The review model was a pre-production sample.
Packaging
The model comes in an outer shipping carton containing a high quality box. Inside, the model is contained within trays.
There were no defects or missing parts on the review model.
Included with the model is a reprint of the original Caterpillar 660 sales brochure and this also has a unique serial number for the model.
Detail
The chassis detail on the tractor is reasonable with screw heads painted so they do not stand out.
The tyres are a touch shiny and they are plain with no tyre branding. The wheels are detailed and seem to be plastic but the colour match is excellent.
The tractor radiator grille is finely perforated with the Caterpillar name embossed on top. Headlights are painted silver.
The engine block is plastic and bears the Caterpillar name, and it is nicely detailed with an excellent colour match to the metal parts. The exhaust pipe is also good with a well defined hole.
The driver's area has a finely textured non-slip surface, and grab rails are thin and metal. Among the highlights are the detailed controls and nicely modelled windshield.
The ROPS and large rear wheel arches are metal with good detail.
The scraper has excellent detail on the pivot with a combination of rubber hoses and metal pipes for the hydraulics.
The bowl has nice casting detail in the sides and there are cutting edges on each side but not the bottom. The applied graphics are sharp and clear, and are in a more modern style than those shown on the reprinted brochure.
The ejector has a perforated spill guard and the hydraulic rams have plastic jackets with a very good colour match.
At the back the rear wheels are impressive and there is nice detail running to the pushing point with bolt heads replicated.
Features
The model rolls smoothly.
There is limited steering on the front axle with minor transverse oscillation. The steering wheel turns slightly when the wheels are steered.
The movement across the gooseneck pivot point is very good for steering and there is also side-to-side and fore and aft movement.
The bowl can be lowered and raised and the hydraulics are stiff enough to maintain any pose.
The apron opens and closes smoothly.
The ejector moves forward and backwards easily.
Quality
This is a very good quality model with a high metal content.
The paint is very good and the graphics are sharp.
Price
The model is fully priced.
Overall
Classic Construction Models has produced a nicely finished and impressive model of the 660. The review model was a pre-production sample so there may be some changes on the released version.
Footnotes
This model was appeared at the end of 2015 in a run of 660 models.
