General - MASSEY FERGUSON 5400 Service Manual

A . General
The lift cover is fitted on the upper face of the rear axle
housing. Via two bushes (8), it supports the shaft (4),
which has the two lift arms (5) (11) splined to it.
A cam (9), screwed on the shaft, inside the cover,
shows the different positions taken by the lift arms.
This information is recorded and sent by a sensor (26)
to the Electronic Linkage Control (ELC) system.
To ensure correct clearance between the lift arms and
the cover, shims (12) are fitted on the left-hand end of
the shaft.
Two friction washers (30) are fitted between the lift
arms and the linkage cover to avoid their direct
contact.
The rear face of the linkage cover supports the auxiliary
spool valves. The ground speed sensor (15) is screwed
in the front of the cover, which also supports the
4-speed PTO control linkage (21), if fitted.
