Problem reassembling gearbox

[Terrytuned]

When assembling a gearbox the layshaft assy should be fitted first to check end float, 2thou between bush and casing check when cold if the casing has been heated  to fit layshaft spindle allow to cool before checking clearance as it makes a difference and tighten the layshaft fixing bolts fully when checking clearance. If its slack you need to shim the front bush if you don't have enough clearance use a thicker l/shaft gasket or remove some metal from the face of the bush.
