A friend of mine who doesnt use computers is working on a 235 for a family member. The dampner pulley is off of the engine right now. He installed the proper motor mount pieces, and is ready to put it back together. Getting the pulley off was easy with a puller. But with the truck grille in tact, he's not going to be able to get a decent swing at the pulley with a hammer of any kind. He asked me if the front of the crankshaft is threaded, because that would make it easy to draw the pulley on. I don't know, but I figure some of you guys will. So my question is: is the crank center threaded, and if so, what is the diameter and pitch of the thread. THANKS

Mike, only if somebody threaded it after it was manufactured (which happened sometimes but not as often as you would hope). Generally speaking if this had been done, the bolt would have still been there...but you never know. If you bend a paper clip in a 90 degree angle with about 1/4" on the short leg and drag it from inside out you will feel threads if any are there. As for diameter and pitch...that depends entirely on whoever threaded it. Good luck!

Remove the radiator- - - - -there will be plenty of room to use a BFH and tap the balancer on. Be sure to drive a hardwood wedge between the back of the bell housing and the clutch pressure plate to prevent damage to the thrust bearing while installing the balancer. Jerry

There is a tool called the crankshaft snout that allows you to drill and tap the snout for the 235. I ordered one a few days ago and it was supposed to be here yesterday, but USPS has it traveling around the country right now. You may want to check it out. Certainly, easier than hammering.
Here is the snout tool. Got it in today and drilled and tapped the snout on the 283. It has a fixture for alignment, the proper size drill bit and the right tap. It took about 10 minutes to do the job. I believe the 235 is the same size as the 283.
