[Healeys] Speedo angle drives

[Rich C]

Robert,

The angle drive will unscrew from the brass drive sleeve without losing oil 
from the gearbox. However, the reason the oil is sitting there in the 
vicinity is because the little oil seal within the brass drive housing is 
probably shot. This will require removal to get the sleeved drive housing 
unscrewed to replace the inner seal, and removal of that from the o/d 
housing will allow gearbox / overdrive oil to come out. Therefore to fix the 
problem properly, the gearbox and overdrive will need to be drained to be 
able to remove the speedo drive brass sleeved housing so it in turn can be 
to be dismantled and the oil seal to be replaced.
