[Healeys] Timing gear removal, again

[Dave Russell]

"If" you did have the chain off somehow, a clam shell type puller placed 
between the two sprocket rows would be the way to get the crank sprocket 
off.

When going back together, thoroughly deburr/smooth the crank, cam, & 
inside the sprockets. I would trial fit new keys also & finish them as 
necessary to get a perfect jam free fit in both the shafts & hubs. Check 
all parts for easy but precise fits before final assembly. In some 
cases, there may be shims behind the sprockets to set perfect chain 
alignment.

I agree, the chain is sacrificial. Damaging the crank or cam is not  an 
option. Any wedging is likely to damage the crank or cam shoulders.
