Crankshaft Pulley Install - UPDATE!

[sconnors]

I'm planning on installing a new crankshaft pulley on the Model A tomorrow. I've searched the threads here and have talked to some folks, and I understand I may have to jack the engine up. I have a new one piece pulley. Any hints, tips, tricks or advice from anyone who has done this would be greatly appreciated!
Thanks
Scott

Was able to get it done today. I had to loosen the rear motor mount bolts, remove the two front motor mount bolts, and remove the throttle assembly and then I was able to jack the engine high enough to get the pulley out.

I have to say I borrowed a Snap On cordless high impact wrench from a friend and what a job! After using a bar and a ratchet, the impact wrench did the trick in no time.

Thanks to everyone who weighed in here, you guys are all great! What a great resource to have when you need some help!!!

Thanks again
Scott

Re: Crankshaft Pulley Install

pull the rear motor mount bolts and the U bolt that hold the front spring in then jack the engine up and it will just clear. you can do with the U bolts inplace BUT you have to jack the engine up above them and it will push in your firewall.

The 2 piece pulley that is screwed together with a left handed thread is much easier.

I went with the one piece pulley after reading a lot of posts here and other places...hope it works out.

I've never had a problem with the new two piece pulley from Bratton. I did have a problem with the one piece piece pulley, I had to ream the pulley before it would slip over the crankshsft. The easy fix would be break the large part of the old pulley off with a hammer like Bud Winfield use to do. The two piece pulley could then be installed easily .

Be careful when jacking up, keep an eye on the throttle assy attached to bellhousing at the top (gas pedal assy).

Re: Crankshaft Pulley Install

Glad to see you went with the one piece. We reviewed the available two piece ones a few years ago and non were correct in size. Snyder's is now making one but the one piece is still the way to go. The one item that you need to watch for is the slinger that is on the crankshaft. Sometimes that is missing, if it is not there the pulley will not stick out past the end of the crankshaft and the nut will bottom against the crankshaft leaving the pulley loose. This will eventually cause a failure.

John,
What was not the correct size the hub OD at the rope seal? or something else
