Mainshaft Assembly
Refer to picture above:
if the profile of the 1st/2nd gear synchroniser
sleeve is as shown above then the following proce-
dure should be followed(new design).
Where the old design mainshaft is fitted refer to the
procedure from page 4/31 onwards.
Eaton have recently introduced a new design of
mainshaft assembly. As both designs are currently
in use strip and rebuid procedures for both are
included in this manual
Mainshaft Disassembly
1. End float may be checked with the mainshaft
assembled by using a dial gauge, as shown, or
feeler gauges. Mount the mainshaft assembly on a
suitable stand. Locate the dial gauge on the gear
and zero the gauge. Raise the gear and record the
reading.
Note:
All snap rings and circlips on the mainshaft
are graded for selective fit. Take care not to score
the bearing surfaces of the mainshaft when remov-
ing or fitting the snap rings or circlips.
Note:
The end float of the gears on the mainshaft
is established in manufacture by machining the
components to fine tolerances. Before disassembly
of the mainshaft the end floats should be checked
to ascertain whether they are within
the recommended limits.
Where end float is found to be excessive it is nec-
essary to check the gears, mainshaft, synchroniser
hubs and bearing sleeve for wear.
