The Maestro's Quiz- June 10, 1996

 One day last week, The Maestro bought a "core" 1966 912 engine
for a not unreasonable price, gambling on the chance that the crank
might be OK.
 The engine had two or three holes in the top of the Case from
#3 Connecting Rod that, although still attached to the crank,
had been bent NINETY DEGREES at the small end, pulling
the wrist pin out of the piston and smashing said piston into bite-size
pieces, making the Case Holy as a result. 
 But that's not the Question right now. What really caught the Maestro's 
eye was that the generator pulley was "offset" to the REAR
by half an inch, and when the Maestro looked down the plane of the
pulley he saw it was indeed badly misaligned with the Crank drive pulley!
He inspected the rebuilt generator that was on the 912 and found it to
be a Stock, small diameter, 12-Volt 912 Unit.

Questions:
1. How come the Generator Pulley was half an inch to the REAR of the
of the Crank Drive Unit?
2. Did anything happen to the generator pulley (pulleys)?




 One cylinder head- the damaged one- was off the engine, but
other head was still attached and couldn't be inspected in detail. 
All that could be checked was to look for obvious screw-ups- like 
broken valve guide bosses. The Maestro looked down  the Intake Port and
found-  you guessed it-  TWO broken Valve Guide Bosses!
 The Maestro popped the valve cover the still-attached
head to evaluate the Rockers. 
 Which is where he first noticed something funny. The 912 Rockers
were held down by 13 mm nuts with self-locking inserts, obviously
not stock, but the intake rockers DIDN'T HAVE THE SADDLE WASHERS ON THEM!
The 13mm nuts were pressing directly on the rocker shafts! Geez.
 The Maestro eyeballed the rockers and pushrods to see what they 
were like. Which is when he noticed that one pushrod was MISSING!
 How can you have a MISSING push rod in an engine that
supposedly was RUNNING before!

That's Question #3.
