I will be shortly starting a r and r of my water pump (84 non turbo).
I dont have a flywheel lock and i am a little concerned that the
engine will rotate when i get the belts off.
Can anyone who has done this job recommend a safe method (besides
flywheel lock) of ensuring that nothing moves when it shouldnt, or at
least if it does......how to get it back to where it should be.

thanks

Really????  is that because it is very easy to accidently have things
rotate when they shouldnt or does it contribute to reducing time by
making things easier to remove etc...........or both.
Now i`m a bit worried....a lot of posts i have read in researching
this have indicated its not beyond those with average mechanical
knowledge with or without the lock

I've done belts and water pumps on both of my cars, and I didn't use a fly
wheel lock.

Basically just set the engine to TDC, do the job, and then insta

I've done belts, water pumps, and head gaskets on both of my cars, and I've
never used a fly wheel lock.

Just make sure the engine is at TDC before you start.  From there on it's
just a matter of pulling stuff off, replacing the pump, putting stuff back
on, and then tensioning the timing and balance shaft belts.

Doing the belts is the most critical part of this job, so make sure you have
all of your ducks in a row, make sure you have some form of belt tension
tool, either KriKit, OptiBelt, or the Porsche 9201, and that you have read
and under stand the procedures at Clark's Garage:

There is no need for a fly wheel lock unless you intend to replace the front
main seals, or the oil pump drive and seals.

I agree with the other posters, but BEWARE - don't do what I did and forget
what you are doing and remove the timing belt and THEN discover that you
can't get the bolt on the front of the crankshaft loose - I turned the
engine a little (it was in gear with the brake set) and bent a valve.  So,
Loosen the crank bolt FIRST, then dismantle everything.  When you put it
back together, make sure its TIGHT - it holds the oil pump drive and if it's
not tight, you'll loose oil pressure (again, don't ask me why I know this).
