[alfa] crank locking tool

["Watry, Andrew (LNG-SFR)" <Andrew.Watry@xxxxxxxxxxxxxx>]

Re the crank locking tool, I personally would not depend on the strength of
the spark-plug threads to keep the piston from moving, per the apparent
design of the Hurlock tool. I've ripped those threads out before with the
factory head-removal tool, and I bet you'd put more force there than that
trying to break the crank pulley nut loose.  They are not strong, especially
on well-used heads.  What's normal spark-plug torque, something like 18
ft/lbs?  That's not much.

You can use a generic VW tool if you have the engine separated from the
trans, but with the engine trans installed, it's a little tougher.  Here's
what I said to the guy asking about it yesterday:  "There is a factory tool
that you can use to lock the flywheel, with the engine and trans in place,
on a 115 car with a hydraulic clutch and bellhousing.  You take off the tin
cover and it slots into the flywheel teeth, bolting to a couple of the 6mm
bolt holes from the tin cover bolts to hold the flywheel from turning.  I
don't think it would work on a 105 mechanical clutch bellhousing.  There's a
similar, probably almost identical looking, tool to fit 116 cars to lock the
ring gear."

I can look up the part number for the 115 tool over the weekend if anyone's
interested.
