CAT 257B3: Problems, Durability, and Specs

The CAT 257B3 or Caterpillar 257B series 3 multi-terrain loader is a compact track loader manufactured by Caterpillar between 2009 and 2015. It was the third generation in the 257b series that Caterpillar started making in 1997. The CAT 257B3 has a more powerful engine, improved hydraulics, and power train than its predecessors.

This article details the key specifications of the CAT 257B3, including its dimensions, engine, hydraulics, power train, and more. In addition, this article explores the problems and durability of the CAT 257B3 compact track loader.

CAT 257B3 Specifications

1) Engine

The CAT 257B3 stands out as a powerful track loader, in part due to its CAT C3.4 DIT engine. It is a reasonably powerful engine that can deliver a gross power output of 74 horsepower (hp) and a net hp of 71. In addition, CAT 257B3 has a displacement of 3.3 liters. Its displacement, 4.7-inch-stroke, and 3.7-inch bore should balance power and durability.

The C3.4 engine in the CAT 257B3 is a significant upgrade on the C2.2t in the second generation 257b, which has a gross power of 61 hp and a net power of 56 hp.

The engine here should be capable of tackling a wide range of demanding tasks on construction sites, including grading, leveling, and loading materials. Yet, some consider the CAT 257B3 engine a bit underpowered, considering its 8000-pound operating weight.

Further, the engine is Tier 4 compliant, making it compatible with the latest US Environmental Protection Agency’s (EPA) emission standards. It also complies with the EU stage IV standards for nonroad engines.

2) Operating Specifications

The CAT 257B3 has an operating weight of 8060.1 pounds and good specifications with regard to its rated operating capacity. At a 35% tipping load, the CAT 257B3 can support up to 1870 pounds. At 50% tipping load, the CAT 257B3 supports 2675 pounds. If the optional counterweight is fitted, the CAT 257B3 operating capacity gets to a more impressive 2725 pounds. This variation provides operators with the flexibility to lift different load weights for various applications or tasks.

Tipping load refers to the weight that would lift the rear tracks of the machine to a dangerous point where it could tip over. The CAT 257B3s tipping load is 5350 pounds. This should give enough leeway for carrying heavy loads without risking performance and safety. The CAT 257B3 breakout force is 4508 pounds.

The CAT 257B3s ground contact area covers 1.13 square meters or 1770 square inches. It should help the 257B3 maintain good traction and stability. With such a vast ground contact area, the weight of the machine can be better distributed. As such, its ground pressure is just 31 Kilopascals (kPa). Also, the CAT 257B3 has a reasonably low ground pressure which should reduce the risk of surface damage, especially on delicate terrains.

Note that the operating specifications described here are based on an operator weighing 75 kilograms (kg), all fluids, a 66-inch dirt bucket, open rollover protection, zero optional buckets, and a manual quick coupler.

3) Power Train

A major talking point for Caterpillar regarding the CAT 257B3 is its high-performance power train. The 257B3 has two power train options, one speed, and two speed.

In both forward and reverse, a one-speed option CAT 257B3 will reach up to 6.9 miles per hour. While not especially quick, it does allow for controlled movement to navigate various terrains with precision.

However, if speed is a significant requirement for you, especially between locations, the two-speed option will have you covered. It can reach a significantly higher speed than the one-speed option at 10 miles per hour going forward or in reverse. This option will enable you or your operators to cover large distances more swiftly. Large projects will also benefit from the two-speed option for quickly executing tasks.

4) Hydraulic System

CAT emphasized the advanced capabilities of the CAT 257B3 on its release. They claim its design will provide maximum power and reliability.

The CAT 257B3 has a loader hydraulic pressure of 23,000 kPa or 3,335 psi to deliver robust force. This level of hydraulic pressure will help the track loader handle large loads efficiently. The loader hydraulic flow is set at 83 liters or 22 gallons per minute. This flow rate will allow for quick cycle times. Also, it will reduce operational delays and help to maximize productivity.

The last highlighted spec of the hydraulic system is the hydraulic power which is calculated at 31.9 kilowatts (42.8 hp). It will allow work with a range of tools and implements for various applications.

5) Service Refill Capacities

The 257B3s cooling system capacity of 2.6 gallons is more than enough to keep the cooling system functioning optimally for a long time, even under demanding operations. This is important for preserving the performance and lifespan of the engine.

The engine crankcase can fill up to 2.4 gallons of oil for lubricating engine parts. The 257B3s fuel tank capacity is 22.2 gallons. The tank size is good for a compact track loader, especially if used for light work like landscaping. In such situations, you will not need to refill your CAT 257B3 with fuel frequently. The 257B3s hydraulics requires 14.5 gallons of fluid. The tank can store 9.2 gallons.

Generally, the CAT 257B3 fluid capacities are respectable and would not need you to refill frequently so long as the machine is in good working condition.

6) Dimensions

The CAT 257B3 is a compact machine that can handle significant weights. This is more impressive because it retains similar dimensions to its predecessor while offering significantly improved transmission, engine power, and hydraulics. It has excellent clearance and ample reach. The compactness of the 257B3 will aid movement through tight areas. The CAT 257B3 cab height is lengthy enough to give tall operators a comfortable space to operate in.

CAT 257B3 Problems

The CAT 257B3 does not have significant problems associated with it. Nevertheless, below are some problems related to CAT 257B3.

1) Rear Visibility Problems

Some users of the CAT 257B3 have complained about the rear visibility of the track loader. This can be problematic for operations that require frequent driving in reverse and in less-than-ideal conditions.

2) Difficulty Starting Engine

This is a situation where starting the engine might take longer than usual or require multiple attempts before it starts. In some cases, the CAT 257B3 engine may not start at all. Causes may include

·       Clogged fuel filters

·       Air or water in the fuel system

·       Dirty injection nozzles

·       Defective fuel pumps

Also, the 257B3 may struggle to start in very low temperatures.

3) Noisy Cab

Operators of the 257B3 may find the cab especially noisy. The noise can be troublesome after many hours of work.

4) Lift Arm Not Dropping or Lifting

In some cases, operators of the 257B3 have had issues with the lift arms when trying to lift or drop them. There are several reasons why this may happen, including defective controls, damaged hydraulic pumps, control valves, or cylinders.

5) Hydraulic Leaks

Without proper and regular maintenance, CAT 275B3 may be prone to fluid leaks in the hydraulic system.

CAT 257B3 Durability

Caterpillar builds durable machines that withstand heavy use. The CAT 257B3 is created in that tradition. Caterpillar made the CAT 257B3 with sturdy and robust materials, and its engine is quite reliable.

Due to the fact that Caterpillar no longer manufactures the CAT 257B3, you will not find a brand new one for purchase, ruling out an official warranty. Be mindful of this when purchasing a used CAT 257B3. So, do due diligence and buy a CAT 257B3 in good working condition to avoid sad stories. A good and working CAT 257B3 will last long if properly maintained and correctly operated.

Conclusion

The CAT 257B3 is an excellent multi-terrain track loader from Caterpillar. This article ran through its specifications, problems, and durability. The CAT 257B3 has solid specs for a compact track loader. Its powerful engine, reliable transmission options, manageable dimensions, and decent hydraulics stand it out.

Like many Caterpillar machinery, the CAT 257B3 is a solid and durable machine that will serve you adequately with proper maintenance. Further, the CAT 257B3 does not have too many negative quirks associated with it. However, keep in mind the cab noise, wonky rear visibility, and other issues we highlighted before making a purchase.
