New Oil Filter Kit P/N 02976069:

Detailed investigation of recent valve failures revealed that in the vast majority of the incidences, the failures are attributable to contamination within the tractor hydraulic systems which supply pressure to the control valve. Failure normally take the form of one or more inoperative or poorly operating functions. Repair may involve the replacement of the electronic controller for the section or, in severe cases, the replacement of the entire valve. Particulate contamination in the form of small gear metal or brass particles created during break-in and operation and are not removed during required maintenance of the tractor can enter the valve, this creates leakage due to wear or clogging of passageways.

In response, an in-line pressure filter and fitting kit (Kit P/N 02976069) has been developed for installation in the pressure line which delivers oil to the valve. The kit provides all the necessary fittings, hardware and instructions to facilitate the correct installation.

Installation of the Filter Kit will greatly reduce the possibility of the occurrence of failures within the Machete control valve due to particulate contamination. This con- tamination may result from poor maintenance of the tractor hydraulic system or other hydraulic system performance characteristics or problems.

An indicator located on the top of the filter housing will indicate when the filter is bypassing thus requiring the replacement of the filter element. The element is a canister insert which is easily replaced by unscrewing the cannister.

In accordance with the published Warranty Policy, failures proven to be the result of contamination of the system oil due to poor maintenance, performance or repair of the supply (Tractor) system will not be compensated under Alamo Industrial Warranty.
