Greetings everyone, Has anyone had the crankshaft pulley off from a 54 Olds? I have two questions. Is the 3/4 nut holding on the pulley right or left hand threads? And does one need a wheel puller to get the pulley off. I have to replace the front motor mount and that crank pulley has to come off.

Thanks, Gawain

 

I ran into something like this before. Here's the thread with a reply from one of the 1954 experts!

OK, I found some pictures. The balancer and pulleys come off together. There's a keyway in the crankshaft, and once the bolt is removed you can pull or gently pry maybe tap with a mallet to remove the assembly. I'm 99% sure they were normal thread, just on there really really tight. But one of the guys who knows this vintage better than I can speak to the thread direction.

 

I have had the one on my 54 off a couple times. If you have an impact wrench it is your friend in getting the bolt loose. It is just a big right handed thread. The pulley and balancer are all made together. It comes off pretty easy. It may take a little soaking and some tapping because it has been on there so long.

If you don't have a impact wrench and it doesn't come off easily you can lock up the flex plate through the starter hole with a crow bar or heavy screwdriver and attack it with a breaker bar...... Tedd

 

You have good advice. I held the engine from turning with a turning tool on the flywheel and loosened the bolt with a 3/4" drive socket and a big breaker bar. If you can't tap the pulley off with a soft hammer you can use a gear puller; just don't pull on the ring. Upon re-installation the Olds shop manual recommends using POB number 3 sealer on the crankshaft and key/keyway to discourage oil leaking. It also recommends using a new lock washer. I don't remember doing either, and nothing leaked or came loose.
Torque to 45-50 ft-pounds.

 

All good advice, and correct. I've had mine off a couple of times. Used an impact wrench. I Also had to replace the front engine mount. Be very careful on the front oil seal. Mine leaks, and I've replaced it several times, and still leaks like crazy.

 

I have the front motor mount -- and the rear bell housing mounts for both stick and automatic, if you need them....
