Case Drain Filter

The PT machines are also equipped with a filter in the

auxiliary circuit case drain line. It protects the main

hydraulic system in the event of catastrophic failure in

an attachment. This filter is designed to last the life of

the vehicle. The only instance where this filter should

be replaced is if an attachment equipped with a case

drain has a drive motor failure during use. (fig. 4-62)

Fuse Panel

The electrical systems in the PT machines are

equipped with fuses that protect the electrical compo-

nents from damage. They are located on the fuse

panel behind the access cover on the lower right side

of the cab interior. (fig. 4-63)

In the event of an electrical malfunction, the most logi-

cal place to start is at the fuse panel. Check the fuse

related to the problem you are having and inspect it. If

the fuse appears black and burned, it needs to be

replaced. Replace fuses with the correct amperage

replacement fuse only. Replacing a fuse with one of a

lower amperage rating may lead to premature fuse fail-

ure. Replacing a fuse with one of a higher amperage

rating may burn out the electrical component the fuse

was meant to protect. See the troubleshooting section

in this manual for an additional resource to aid in track-

ing suspected electrical problems.
