Have you ever noticed whether your equipment has an existing leakage problem? Most people in the early stage do not regard the leakage seriously, until the equipment appears a severe problem and then discover their equipment has a serious leakage. So, is the leakage a normal phenomenon, or is it a sign of a serious problem? Understanding which is a normal phenomenon and which is a warning signal is the key to avoiding costly downtime. This guide will instruct you on how to identify different types of leakage, how to diagnose leakage according to the color of the liquid, how to understand the common causes of heavy-duty equipment air conditioning leakage, and how to take proactive measures, making your system remain running cool during the whole season.

If you find that the engine power of your equipment is not like before, or it needs to consume more fuel, then the problem may lie in the intercooler. Especially for heavy-duty equipment, most of them are equipped with an intercooler on the turbocharged diesel engine, in order to help discharge the heat generated by the air compression. If your engine shows too many abnormal phenomena, maybe the intercooler needs cleaning or repair. Therefore, this guide will explain the signs that a turbocharged diesel intercooler requires maintenance and provide a detailed step-by-step cleaning process, so that the power and efficiency of the machine can be correctly restored.

Quickly look up common Kubota error codes for DPF, fuel pressure, and hydraulic systems. Our guide provides a lookup table and explains frequent faults on SVL, KX, and L-Series models. Learn the step-by-step process to properly reset Kubota error codes and get your machine back to work.

The air conditioning is of vital importance to the comfort of operating the heavy-duty equipment, especially in the seasons when the temperature is elevated. However, the working environment of the air conditioning system of the heavy-duty equipment is of an extremely harsh character—unceasing vibration, suffocating dust, and endless utilization—such conditions are making the system more easily to become damaged. Therefore, the question of how long the air conditioning can be used in the daily operation of the equipment is one worthy of concern. For this reason, this article will be making a realistic evaluation of the average service life of the heavy equipment air conditioning system, exploring the factors which are influencing its longevity, identifying the warning signals of the failure, and providing the practical techniques to extend its lifespan, thereby assisting you to maintain the operator in the cool condition and to ensure the smooth proceeding of the project.

You’re driving along when suddenly your temperature gauge spikes, or maybe you notice white smoke billowing from your exhaust. These could be signs of cylinder head failure – one of the most expensive engine problems you can face. At FridayParts, we’ve seen countless cases of cracked cylinder heads, and we know how frustrating this can be for equipment owners.

If the air conditioning system is failing under hot weather, it maybe will cause operator fatigue and costly downtime. Although many people perhaps will suspect the major components, such as the compressor, the problem often originates from a smaller and frequently misunderstood part: the AC dryer. Neglecting the health condition of this part is a mistake, which may lead to a series of failures in the entire air conditioning system. This guide aims to provide you with the professional knowledge you need. We will accurately explain the concept and working principle of the air conditioning dryer, elaborate on the six key warning signals of its failure, show you how to identify these symptoms, and clearly indicate when the dryer must be replaced.
