Rebuilding is reasonably straightforward but there are some important points to note.
First make sure that all the components are clean, then examine them for signs of
scoring or wear. This includes seals, thrust washers, thrust bearings, clutch plates etc.
Lubricate all the gears and clutch plates with Dextron fluid before installation,
and you may find it useful to locate thrust washers and bearings in position
with petroleum jelly.
To rebuild second and third clutch assemblies you will need the same special tools
that were used for dismantling. Use them to compress the clutch springs so that you
can fit the retaining circlip.
To fit the clutch discs, start with the cushion ring, then fit a plain steel disc
followed by a clutch lining disc. Continue fitting alternate discs, the last to be
fitted is a plain steel disc.
Before fitting the one-way clutch into the third gear clutch, check its operation
like this. Hold the assembly and check that the sun gear will turn freely in an
anticlockwise direction. As soon as you try to turn it clockwise it should lock.
Continue rebuilding the gear train in the reverse sequence to dismantling.
