Kubota B5100 Parts – New and Aftermarket

Kubota B5100 parts

The Kubota B5100 is a B series sub-compact utility tractor, first produced in about 1978, and in production for roughly 6/7 years.

It has a 0.5 litre, 2 cylinder diesel engine, with a power output of about 12 hp, and a PTO of approx 10 hp. It has a fuel capacity of just over 2 gallons.

It has hydrostatic transmission, power steering and a wet disc braking sysytem.

Replacement parts for the Kubota B5100 may be needed at any point in its lifetime, either as replacement parts in a routine service, because a part has become defective or simply because of old age!

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

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 B5100 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 tractors and agricultural machinery. It is really important to check the specific item needed prior to purchase, especially if bought online

Kubota B5100 Parts category

Batteries

Kubota batteries use the most current technology to make sure there are sufficient and powerful as possible. These normally include a negative plate paste expander, and a sodium sulphate additive.

Belts

Kubota mower belts are claimed to last up to 3 times longer than comparable aftermarket products.

In addition, they are made in what is called an alignment line, allowing the courts to equalise the energy distribution flow. This results in a more stable tension. In addition, they contain fiber enforced rubber that helps support the integrity of the belt

Kubota B5100 Filters

Engine oil filters

An oil filter is meant to help reduce or eliminate any potentially damaging element may be produced by the engine oil to date the activity

Hydraulic filters

A Kubota hydraulic filter is designed to do a similar job to an engine oil filter, but the hydraulic system, thereby protecting valves and hydrostatic transmission parts, which are an integral part of keeping the tractor operating safely and efficiently

Other types of filters include a suction filter, an HST filter, a fuel filter and an outer air filter.
