The CAT (Caterpillar) 420D and 430D backhoe loaders are the high performance machines in the D series lineup. The 420D boasts 85 HP and a backhoe digging depth of 14 feet when equipped with a standard stick.  

The 430D offers 94 HP and a backhoe digging depth of 15 feet when it is equipped with a standard stick. By using an extendible stick, you can push the digging depth of the 420D to 18 feet and the depth of the 430D to 19 feet, which is very impressive to say the least.

Both D series machines are available in IT (Integrated Toolcarrier) configurations for applications that benefit from a parallel lift loader linkage and the versatility of quick work tool changes through the use of a versatile hydraulic quick coupler. Applications include the use of pallet forks, material handling arms, brooms, and even buckets.

The new and improved pilot operated hydraulic backhoe and IT loader controls will help to ensure smooth, precise operation with reduced effort on behalf of the operator. These backhoes use excavator type joystick controls, and an optional pattern change valve which allows you to select the patern of control.

The 205 degree rotation that is offered by the backhoe bucket linkage will make it easier to dig vertical walls and clamp material when loading trucks. The rotation with the D series is 40 degrees more than with the C series. Now, the backhoe buckets feature a single pin position, with the bucket link featuring an integrated lifting eye as well.

The optional quick coupler you can get for the backhoe will allow fast changes of working tools for increased versatility and flexibility in almost all applications.

Both of the D series backhoe loaders use the turbocharged, direct injection, four cylinder diesel engine, with a displacement of 4.0 liters. This engine offers superior lug performance which is mostly due to the responsive fuel injection system.

The standard power shuttle transmission provides four forward speeds and four speeds in reverse as well. Fully synchromesh in all gears will permit on the go shifting, while the forward and reverse electric power shuttle will provide instant direction changes through powered clutches.

The auto shifting feature will automatically shift between second gear and the highest gear selected for ease of operation. The auto shift feature has five forward and three reverse gears, with a transmission kick switch on the lever of the loader control.

With D series loaders, you’ll also have the choice of standard two wheel drive or all wheel drive, which you can engage easily on the go, under heavy load, by pressing a switch that is located on the front console.  

The D series loaders from CAT are very fast and versatile as well, as they will move faster than most types of backhoes on the market. The diesel engines are very fast, while the machine has enough traction and control to keep you moving even in wet or muddy conditions.

The variable load sensing hydraulic system will adjust the flow and pressure of the machine to meet the demands of work with an increased pressure of 3,300 PSI. The hydraulic system is tuned to work efficiently with the engine, and it provides full hydraulic force to the working tool on hand at any engine speed you desire.

Unlike other backhoe loaders, the D series will reduce demands on the operator, cut fuel consumption in half, reduce wear on the engine, and allow for quieter operation. To make a long story short – the D series from CAT are among the best backhoe loaders that money can buy – bar none.

We are working on a project up North (Nunavut, Cit anada) and there is 45,000 Gallon of JP-4 left there by the USAF in the mid-80′s (probably when they turned to JP-8). That’s a large volume we would preferably reused than shipped and disposed at high cost in the south. If possible, we are looking forward to mix the JP-4 with additives and use it in the heavy equipment (excavators, trucks, loaders, etc). Some info gathered on the internet mentionned to mix JP-4 with 10W30 motor oil, but we need a precise answer as we cannot afford to damage the diesel engine of the equipment. Thanks a lot for your help !

One of the most important regular services, when working with commercial machinery, is the engine overhaul.  Most commercial machines (tractors, bulldozers, trains, motorised cranes) are diesel engine, as diesel produces longer lasting power at decent cost efficiency than standard petrol.  A critical part of any commercial concern that uses large machinery, then, is a proper stock of diesel engine parts.

Having the correct store of diesel engine parts can significantly increase the engine life of a heavy duty machine.  A company’s inventory of diesel engine parts ensures its ability for quick response to mechanical problems and allows for proper overhaul – which prevents serious problems from occurring in the first place.

The most widely-used commercial machinery (heavy hitters like Caterpillar, Komatsu, Detroit Diesel and Cummins) doesn’t necessarily need overhauling using diesel engine parts manufactured by the brand in question.  Spare diesel engine parts are manufactured and supplied by companies like KM Products Ltd, who have been shipping gaskets, bushing, bearings and cylinders to fit all major industrial machines for over 40 years.  Buying diesel engine parts direct from companies like KMP allows customers to build a working supply relationship with a single trusted concern, rather than having to wait for unwieldy after-sales assistance from bulldozer and tractor manufacturers.  Diesel engine parts made by independent companies are machined with precision to fit the engines of all the leading heavy equipment brand machinery and are fully endorsed by the equipment manufacturers.

Building a relationship with an independent supplier of spare diesel engine parts ensures that a rolling stock of the right bits is available at all times.  The normal benefits of regular supplier relations (bulk discounting; automatic restocking) allow companies that use fleets of heavy diesel vehicles to make significant savings on their maintenance bills.  And because independent companies only build spare diesel engine parts (rather than whole machines), it can often be the case that their turbos, pistons, V-belts and camshafts are actually slightly better than the original component.

Someone who builds spare diesel engine parts for heavy machinery like a Cat can design in a way that Caterpillar themselves can’t.  Not that there’s anything wrong with Cat brand diesel engine parts – but while Caterpillar are busy designing treads and shovels and piston arms and cab controls, an  expert company like KMP can be concentrating solely on the moving bits of the engine.  In effect, the independent diesel engine parts company becomes a dedicated machine shop with the time and resources to develop and test more effective pieces of the same engines.

As such, the independent supplier of diesel engine parts can prolong the life of even the most hardworking engine.  Engines, after all, are what they do.  For expert advice and top-quality kit, they can’t be beaten.
