sound crazy, but the crankshaft pulley (the round thing) sheared off, so the belt is not secure anymore. What is the part i need to replace, and is that an easy fix, or major overhaul?? thanks, R

Replacing the crankshaft pulley is done by removing the crank nut and pulling the old pulley off and putting the new pulley on. You may have to remove the radiator and jack up the front of the engine. For part number information, we will need the engine type. Does each head have 21 or 24 studs? Is the distributor mounted on the front of the engine or the side? Does the pulley have one groove for the belt or 2? Tom

Thank you Tom, it is a 24 bolt, and distributor mounted on the front of the engine. Here is a pix taken from bottom of car looking up. As you can see the pulley is missing half (looks like it was taked welded) thanks again, R

ramin looks like a mounting bolt for the distributer is missing, you might want to install one,before the distributer gets too loose and causes another problem, the PULLEY should go on with no problems, you could try JOBLOT in NY for a new one, also check your belt to make sure it is ok,and adjust the belt with correct tension, KEEP ON TRUCKIN 37 RAGTOPMAN

Replacing the pulley is a straightforward job. You remove the "ratchet nut" that screws into the front of the crankshaft and work the hub of the pulley off the crank. This may require some "persuasion", as most are somewhat stuck. Finding a replacement will take some doing, as there are few repros. C&G has some used pulleys. You will need to sort out which you need, as the car and truck pulleys are often different. I'd guess a 18-6312 will fit if the engine is actually a '38. If it is a later engine, a 91A or 21A may be requited. You can see the choices in the C&G online catalog, page 87. Their site is www.cgfordparts.com

The 18-6312 pulley should work fine in your engine. The 91A pulley is identical except it has the provision for mounting the fan. The 21A pulley has two grooves to take care of the change in mounting the fan. Try Little Dearborn in MN http://littledearborn.com/ or Joblot in NY http://www.joblotauto.com/ Mike Dennis in NE http://www.fordoldpart.com/index.htm or Lowell Kimble 402-649-1116 call them, instead of looking at their listings. These vendors all have some NOS parts that are limited in quantity and not listed on the web sites. You could also advertise for a used one on this site and on the Ford Barn. If you go for the used one, I would replace the front seal with the full circle one. This entails removing the timing gear cover and the oil pan and it is better to pull the engine to do this. Tom
