Komatsu 6140-60-1110 Water pump

Product representation

Detailed product information

Structural composition: mainly consists of a pump, the working wheel, shaft, bearings, seals, pulleys and other components. The pump body is usually made of high -strength cast iron or aluminum alloy, which has good wear resistance and corrosion resistance. The working wheel is usually made of bronze or plastic and has special shapes and angles of the blade location to ensure the effective supply of coolant.

The principle of operation: the pulley of the water pump is driven by the engine with a pulley, which in turn drives the water pump shaft, forcing the working wheel in the pump housing, creating a centrifugal force that sucks the coolant from the intake hole for water, and then squeezing it out of the final Water openings, thereby circulating Cooling liquid in the engine cooling system for the removal of heat produced by the engine.

Applicable models: There are various models suitable for different models of Komatsu excavators, such as PC110, PC130, PC200, etc.

Stages of installation

Preparation: Put an excavator on a flat, solid surface, drown out the engine and disconnect the negative wire of the battery. Prepare the necessary tools such as wrenches, screwdrivers, heads, etc., as well as a new water pump and corresponding seals, lubricants, etc.

Drain the coolant: find the drainage valve tap and drain the coolant into a suitable container.

Disassemble the accompanying details: remove water pipes, belts and other parts connected to the water pump, weaken the bolts fixing the water pump, and remove the old water pump from the engine. Be careful and save the removed bolts, gaskets and other details.

Clean the installation surface: use a clean fabric or brush to clean dirt, rust, etc. from the surface of the water pump and engine unit so that the surface of the installation is flat and clean.

Install a new water pump: apply the required amount of lubrication or sealant to the sealing surface of the new water pump, correctly install the water pump on the engine and tighten the fasteners, paying attention to tightening them in accordance with the indicated puffing moment.

Connect the water hose and belt: connect the water hose to the water pump, making sure of the reliability of the connection and the absence of leaks. Set the belt and adjust the belt tension to the desired level.

Add the coolant: slowly add a coolant that meets the requirements through the intake hole of the radiator, and at the same time open the exhaust valve in the cooling system to release air from the system until the coolant level reaches the specified value.

Checking and testing: Launch the engine and check if the water pump works normally, whether there are water leaks, extraneous noise, etc. Check if the coolant temperature corresponds to the norm and whether the cooling system works well.

Common malfunctions

A water pump leak: this can be caused by aging or damage to seals, such as sealing rings, gaskets, etc.; Also in the pump housing can be cracks or sand sinks; Or compounds of water pipes can be weakened.

An unusual noise of the water pump: the wear of the bearings, the weakened working wheel or friction on the pump housing, the incorrect belt tension, foreign objects inside the water pump, etc. - all this can be the cause of abnormal noise.

The water pump does not rotate: the power problem, for example, burning the fuse, breaks of the line, etc.; engine malfunction, for example, a short circuit of the winding, engine burning; The protection device from overload worked; The working wheel of the water pump was stuck due to foreign objects.

Poor circulation of the coolant: damage to the impeller, clogging of the pump, a malfunction of the thermostat, leading to its incorrect opening, etc., affect the circulation of the coolant and lead to an overheating of the engine.

After -sales service

Warranty Policy: As a rule, Komatsu water pumps have a certain warranty period after purchase, usually 1 year or in accordance with a specific product and contract of sale. If during the warranty period there is a failure due to inhuman factors, you can use free repairs or replacement.

The service network: Komatsu has an extensive network of after -sales service around the world. Users can check the nearest authorized service centers through the Komatsu official website or a hot service line of customer service to facilitate repair and maintenance.

Technical support: Komatsu provides users with professional technical support. If users are faced with problems during use, they can call the customer support service or consult with technical specialists at the local service station.

The supply of accessories: Komatsu can guarantee timely supply of original water pumps and relevant accessories, guaranteeing the quality and compatibility of accessories to ensure normal maintenance and use of water pumps.

To determine whether the replacement of the water pump of the excavator Komatsu is required, you can start with the following aspects:

Cooling fluid leak: check the area around the water pump, water pipes and the lower part of the engine. If the obvious leakage of the coolant and the coolant level continues to fall, after excluding the possibility of leakage from other components, if the leakage place is in the seal of the water pump (for example, the seal of the water pump shaft, the connection of the pump body) or cracks or sandy pumps appeared in the water pump housing sinks that cause coolant leakage, this indicates that The sealing elements of the water pump are damaged and the water pump may need to be replaced.

Unusual noise of the water pump: when the engine works, carefully listen to if there are no unusual noises near the water pump. If the water pump bearing is worn out, it will make a sound similar to “buzzing” or “creak”; If the working wheel is weakened or rubs against the pump housing, a sharp sound of friction can be heard. If these obvious abnormal noises arise and they cannot be eliminated by adjusting the belt tension, etc., this means that there is a problem with the internal components of the water pump, and you should consider the possibility of replacing the water pump.

Poor coolant circulation: monitor the engine coolant temperature. If the engine often overheating under normal working conditions, the temperature of the radiator is uneven or you touch the upper and lower water pipes of the radiator and find that the temperature difference is too large (under normal circumstances of the temperature of the upper and lower water pipes should be close), then the impeller of the water pump may be damaged, the blades can be strongly worn out or the pump body may be clogged that leads to poor coolant circulation. After the exclusion of other factors, such as a malfunction of the thermostat, it can be determined that the problem is in the water pump, and it must be replaced to restore normal coolant circulation.

The abnormal rotation of the water pump: check the rotation of the pulley of the water pump. If you find that the pulley is swinging or clearly getting stuck during rotation, or the water pump shaft rotates non -bending or cannot rotate at all, it can be caused by such reasons as jamming the water pump bearing, damage to the shaft or stucking the impeller by extraneous objects. If such an abnormal rotation occurs, the water pump can no longer work normally and it should be replaced in time.

The water pump vibrates too much when working: a water pump, which works normally, vibrates less. If the vibration of the water pump increases significantly during operation, this can be caused by an imbalance of the internal components of the water pump, damage to the bearings or weakening of the fasteners. If the vibration is too strong and it is impossible to eliminate it with simple methods, such as the tightening of the bolts, this means that the working condition of the water pump is unstable and, possibly, it is necessary to replace the water pump to ensure its normal operation.

The service life and wear: even if the pump does not have obvious signs of a malfunction, with its long -term operation (usually for more than 5 years or with a large number of hours developed), bearings, work wheels and other parts inside the pump inevitably wear out and age. In this case, in order to avoid sudden breakdowns affecting the normal operation of the excavator, one can also consider the possibility of preventive replacement of the water pump.
