Anyone do this engine holder mod?
Not exactly a factory finish but practical. and provides access to the crank bolt without having to lower the motor and remove the engine holder. crank bolt torqued to 173 lb ft...

Yikes.

Why would you ever??? There are 6 easy bolts to remove to pull the whole carrier. I wouldn't think that the huge crank holding tool would fit with the carrier in place. I'm hoping that an impact wrench wasn't also involved. The carrier is not known to be strong to begin with. Nothing good about this idea.

thanks for the comments. perhaps a little impulsive. i dont have that pulley holder tool and torqued the bolt by holding the other end of the crank.
i found it very difficult to spin the crank while trying to index the distributor so chopped the hole. i may not keep this engine holder long term and may be looking to purchase the rennline or other. also need new pillows...
what about when checking valve clearances? do you lower the motor to get access to spin crank or is there a special tool also?

No need to lower the engine for to check the valve clearances.
You use the alternator shaft to turn the engine. Should have the tool in your tool kit. It's a 12 point (3 - square) allen wrench.
Good info here:

I'd really think about reinforcing that carrier since you put a hole in it, if you haven't already done so. It's a known weak part.

Interesting, here are my observations.
Yes the carrier is a weak spot, but not where you have cut the hole. The weak spot is at either end of the carrier where the sheet metal is welded to the round tabs that bolt to the engine mounts. If you had drilled a hole rather than cutting in the manner you did it would have been better. You have introduced stress points where you have cut the hole, (extended the cut past the hole) if you are keeping the bar then i would address them, if replacing don't worry.
You should never torque the pulley bolt by holding the flywheel end of the crank, always use the pulley holder. You run the risk of tweaking the crank shaft, which can cause a myriad of issues including catastrophic failure....

To the OP- That maybe isn't ideal but I don't see it ever being an issue. I've seen a lot of failed engine carriers but never in the center. I think the loss of strength is negligable, but maybe gusset/reinforce it next time you have it out just to be safe.

When removing the crankshaft pulley or loosening the crankshaft pulley bolt it is possible that the hole for the locating pin in the pulley may get damaged. Reinstallation of the damaged part with an elongated hole could cause the valve/ignition timing to be maladjusted. To avoid this, inspect pulley for elongated hole. If damaged, replace.
A new pulley, part number 930.102.024.03, has been introduced with two bores. A pulley holder, tool number 9236 is now available to aid in easier removal and preventing the possibility of damage.

thanks for the comments and proves there are rednecks in Canada also!! and going to be more with President Trump (Doh!!) Okay. Off Topic.
i'll look into the pulley tool and i cannot spin the motor with the 12 point (triple square). engine is too tight to spin it from the belts... perhaps where my timing issues originate..... which i am going to address this weekend.
