Looking for inspiration.  The clutch job I helped with would have been easier with a flywheel lock.

Inspire me please.

On Volvo 240s when doing a timing belt I used to put soft rope down number one cylinder at TDC to lock the engine up. Of course you want to leave plenty of rope outside the spark plug hole so you can pull it out.

Take one of the top two transmission housing bolts. Put the box end of a 15mm wrench over the bolt, then screw it into the block. Use the open end to lock the flywheel in place as you break the bolts free.

I take a piece of sheet metal, Bend it into a U, drill a hole, bolt it to the block with the open end stuck into the ring gear.

I know an ‘86 is an 8 valve, but on my 16v the flywheel would be closer to the transmission than the engine. Is it the same on those?

Not sure if the above is confusing, but iirc it was:

engine -> pressure plate -> disc -> flywheel -> transmission.

In reply to Slippery :

All 020s are like that - the pressure plate bolts to the crank, the flywheel is a ring that bolts to the outside of the pressure plate, and the clutch is disengaged by a little rod that goes through the input shaft.

 

Kind of a neat setup since it's so light, and easy to make even lighter.  Downside of couse is when the pushrod seals go and it starts drooling gear oil on the clutch, but this didn't happen as often as Murphy would have you think.

86 means it should be an 8v o2o combo. Yes the pressure plate bolts to the motor then the disc-> center plate-> flywheel.

Not sure if it was mentioned but the 16v pressure plate is a nice upgrade on the cheap.  For another 40-50 most shops will balance / lighten you stock flywheel by a few lbs.  just a few nice cheap upgrades.  Diesel motor mounts are the cheapy poly substitute.

Indeed..

engine -> pressure plate -> disc -> flywheel -> transmission

So I guess I would need one holder/ for two functions.  One to hold the pressure plate in place while torquing the crank to pressure plate bolts and another to hold the flywheel to pressure plate bolts.   Unless I snug the flywheel in place, torque the pressure plate/crank bolts and then remove the flywheel, install clutch disc and reinstall flywheel.  *whew*  I am tired just typing that.

Not exactly how I do it but close enough. Thanks google!
