Kubota AV6500 Generator Parts

The main parts of the Kubota AV6500 generator that may need replacing at some time are listed below. They may need replacing either through some type of mechanical breakdown or damage, or simply as part of routine maintenance over a period of time.

With all Kubota AV6500 Generators and engines it is important to check what emission regulation thet comply with, normally either Tier 4 or Tier 2. It is also important to check its intake system – many are naturally aspirated.

Parts can normally be obtained either from Kubota itself, or from a third party supplier.

Kubota AV6500 generators can be used a saccessories in many different types of machinery and vehicles, ranging from tractors to air compressors, saw mills, water pumps, zero turn mowers, sea weed harvesters, trenchers, wheel loaders etc.

Many of them are also compatable with tractors and machinery made by other manufacturers.

Replacement parts made by another manufacturer are normally referred to as aftermarket parts. Aftermarket parts should perform the same function as a standard manufacturer part, but will normally be cheaper.

If the Kubota AV6500 generator is still under warranty, then it is likely to be part of the warranty conditions that manufacturer parts are used. A number of people also prefer manufacturer parts because there are specifically designed to be used with the appropriate tractor.

Below is a breakdown of the main areas and categories of parts used in most Kubota generator, engines, tractors and agricultural machinery. It is really important to check the specific item needed prior to purchase, especially if bought online

All measurements listed below are approximate and should be checked with the manufacturer /dealer or manual before any purchase is made or any repairs undertaken.

Kubota AV6500 Generator and Engine Manual PDF

The operator and service manual for the Kubota AV6500 generator, sometimes referred to as a workshop manual is most easily accessed as a PDF document, and can be downloaded either from the main Kubota website, or from a number of other websites online, either as a free download or normally at a minimal cost

The manual is a crucial document in terms of advising both how to disassemble and service the engine in a safe and efficient way, and at the same time keeping all its operating parts running smoothly and effectively as possible

The Kubota AV6500 parts diagrams that are part of the manual are important in helping anyone to fit or repair a replacement part, either as part of a routine service, or because the part has become defective.

The Kubota AV6500 generator PDF manual has a number of sections, which would normally cover the mechanism and servicing and disassembling areas of operation.

It is always a good idea to do a pre-operation check, to see if there are any signs of problems that could indicate parts needing to be replaced. Some inspections include checking to see if there are any parts which have had problems in previous operations.

Walk around the engine to see if there are any oil or water leaks, checking the engine oil level and the amount of fuel. Check the amount of coolant in the engine and seeing if there is any dust in the air cleaner dust cup. It is also a good idea to check if there are any damaged parts or any loosened bolts or nuts.

When starting the engine, it is a good idea to check the colour of the exhaust fumes, and listen to see if there is any unusual engine noise which could give an indication of some malfunction inside it.

Kubota also give a detailed breakdown how often various parts should be checked to see if they need replacing or cleaning. This is indicated by how many hours the engine has been running for. As an example, for most engines it is recommended that every 200 hours the engine oil is changed, and the intake airline is checked.

Every 3000 hours, it is recommended to check the turbocharger, check the injection pump and check the fuel injection timer.Every two years it is recommended to change the radiator coolant, to change or replace radiator hoses and clamp bands, to replace fuel pipes and replace the intake air line.

For full details please refer to the service owners manual.

Kubota AV6500 Generator – Injection Pump

This engine has a unique injection system pioneered by Kubota. What it does in effect is to provide a high level of power output, that is combined with a torque backup.

In addition, the way the pistons are designed and coated means that the valves vibrate less than in a lot of comparable diesel engines, meaning that there is generally much less noise from the engine that would otherwise be.

The issue of noise can be a significant factor in any engine that is running for a long period of time continuously, especially if it is in a confined area.

The Kubota generator uses a unique casting technology made by Kubota that gives the engine a high level of protection against the heat generated by the power of the engine.

This gives the engine an increased level of reliability, as well as high level of endurance.

Its design also gives it a way of starting quickly in cold weather, which is not only convenient, but in many ways can also be hugely beneficial in terms of productivity and work performance..
