Crank Nut
Is the crank nut on the front of the crankshaft difficult to remove with the engine and radiator in? Are they available from the part houses?

Re: Crank Nut
They are available and you can remove them with engine and radiator in place. Suppliers make a special offset wrench for the job. A socket and breaker bar won't work with the radiator installed, but the special tool will.

Re: Crank Nut
I've done it with a socket and a breaker bar, but you have to slip the socket in place first from behind the radiator, and then slide an extension through the crank hole. Break it good and loose, then remove the tools and turn it out the rest of the way by hand.
It is a big socket, 1 3/8", larger than NAPA or anywhere else had on the shelf. Oh, and it's a bolt, not a nut: http://www.brattons.com/product.asp?...rKeywords=8910

Re: Crank Nut
It is not a nut, it's a bolt, and if you do it like KGBnut suggests , you can use an impact to loosen it.

Re: Crank Nut
I go through the spokes on the backside of the pulley with a sharp air hammer chisel to loosen mine. After a little of my famous Blue Loctite, I tighten it with a round ended chisel, in the same manner. That's called an Okie Impact Wrench! (OIW) BRRRP! BRRRP! Bill W.

Re: Crank Nut
I used a 1 3/8" box wrench to make my own tool and I also lay the wrench handle on the frame and hit the starter with the key off.

Re: Crank Nut
My rig fits and works on a Model B...I'm pretty sure clearance is about the same on an A and that it would work. If it fits it is a very convenient tool...
Recipe: Sears 36 MM socket, 1/2" drive. This fits, and is chosen because I could only find the inch equivalent in 6 point 3/4 drive sockets that were too bulky to go in there. Slip socket in fitted with the little plug Sears sells that allows it to be turned with a flat wrench. I cannot remember what this thing is called...it is simply a 1/2" square that snaps into socket with 3/4" hex on top. Add in a ratcheting 3/4 box wrench and you are done. These come both flat handled and with an offset handle. To break the thing loose or tighten it, you just apply "Okie Impact Wrench"... with wrench sticking out in an appropriate direction, give the end a good smack with a rubber mallet. |

Re: Crank Nut
This wrench, that mimics the original service tool, takes the ratchet bolt off and it makes timing the ignition easier. The wrench is available from "A" parts dealers or you can make one yourself from a 1-3/8 box wrench.
