Mainshaft Disassembly
Old Design
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.
1. Mount the mainshaft assembly, plain end upper-
most, in a soft jawed vice. Remove the synchronis-
er ring. Carefully slide the 5th/6th synchroniser
sleeve upwards until the three rollers are clear of
the groove in the synchroniser sleeve. Remove the
three rollers, the synchroniser sleeve, the three
plungers and three springs from the synchroniser
hub.
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 recom-
mended 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. See ’Inspection
of Expendable Parts’ and renew where necessary.
End Float Check
End float may be checked with the shaft assem-
bled by using a dial gauge as shown.
2. Remove the 5th/6th-gear synchroniser hub
retaining Circlip.
