Kubota U45 Parts – New and Aftermarket

The U45 is a Kubota U series mini excavator, first produced in 2003, and in production for roughly 2/3 years. It is powered by a V2203-M-EBH2 , 4 cylinder diesel engine, with a rated ouput of approx 40pk / 2250 rpm. Its body width is 1700 mm, its width over tracks 1960 mm, a track width of 400 mm, exerting a ground pressure of 0.26 kg / cm2.

Performance and safety is key to any excavator, and obtaining and fitting the correct parts is a crucial element in maintaining its longevity as a machine, and its safe usage whenever it is in operation.

When looking for parts, it is often a good idea to try and obtain a copy of a pdf manual as well.

When buying parts for the Kubota U45, it is a good idea if possible to have the chassis number of the excavator, as well as being able to be as specific as possible as to which part is actually required.

This will help to track the part, and also help in locating a manual if needed which will contain diagrams for the specific part, and greatly help in being able to fit it properly.

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 U45 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 excavator.

Below is a breakdown of the main systems used, and their component parts, in most Kubota excavators. It is really important to check the specific item needed prior to purchase, especially if bought online. Please be aware that measurements of all parts and all product details are approximate only and should be verified with the manufacturer before any purchase.
