Hi Jerry,

It's normal for the synchro cups to stick to the cone ends of the gears,
after all they are really little clutches.  I use a screw driver to pry the
cups away the mating surfaces on the gears and then check to make sure the
shafts turn freely.  I also engage each gear and verify smooth operation.
Sometimes the cups have to be pried loose after a gear disengaged.

| I have just overhauled my gearbox and added new bearings, seals and
synchro
| cups (3).  The gearbox is still on the workbench without the cover
(shifter)
| on.  When it is set in neutral there is almost slippage between the input
| shaft and the output flange when I turn the input by hand, but when I hold
| the output flange it is hard to twist but there is some slip.  It looks to
| me like the synchros for 3rd and 4th are too snug to the their gears.  Is
| there a way of freeing these up without total dissassembly?  Any hints
would
| be helpful.
