Powershifts

NTF rear axle and transmission filter

Modern tractors often have the same oil sump for the rear axle and the transmission. In this same oil also the wet brakes are mounted. It is well known that this oil sump gets contaminated during operating hours, but due to ever more sensitive systems, this contamination can result in inconvenient defects.

These powershifts are filtered by so-called full flow filters, which have a limited filter retention value. This value can not be to low because the main oil flow has to run through this filter unrestrained. Laboratory research and analyses at the scene have shown that the full flow filters

are only effective at 20 micron and higher. The amount of particles bigger than 20 micron however is considerably lower (approximate 1000%) as the amount of particles smaller than 20 micron.

Proportional valves have such sensitive tolerances to these contaminations and can cause, in case of poor quality or non-functioning valves, defects of several functions. Over 80% of all failures are related to contaminating particles under 20 micron.

By applying a NTF bypass micro filter, this contamination can be reduced by 90%, as result of which the number of defects will decrease significant.
