![]() Work alternator into place and slide all-thread rod threw front bracket. Start this into rear bracket and install pipe you have cut as shim. Use your all-thread rod, put washer, lock washer and nut on one end. Remove tension bracket (mine had two bends in it) get bracket on solid surface and straighten bends with hammer (it needs to be straight) after you have done this reinstall. Cut your all-thread rod to that dimension. Next measure from front bracket to back bracket and add enough to that dimension to except two lock washers, two washers and two nuts. (Mine was minus two inches) this will give you the dimension you need to cut the 6" piece of pipe. Now measure from the front bracket to the rear bracket and deduct the Alternator mounting position. With the pieces of pipe you cut, shim out the front part of the bracket (stud and bolt) Attach front bracket to water pump. Take the 4" x 3/8" bolt and cut off threads and cut it long enough to accept the top part of front bracket plus shim, drive it into place where stud was and install galvanized pipe shim. Next is for the replacement for the stud you removed from the water pump. With the extra dimension you need to get front bracket out to be in line with outer pulleys, cut you two pieces off the 4" x 1/2" galvanized pipe (this is best done in vise) I needed 12" 7/16" all-thread rod, two lock washers, two nuts, 2" x 3/8" bolt, 3" x 3/8" bolt, 6" x 1/2" ID galvanized pipe, 4" x 1/2" ID galvanize pipe, 3' number 8 wire, wire-end terminals and metric bolt and lock washer to fit Alternator hole for adjustment mounting bracket. Now you need to make a list of things you need. Remove upper stud, it will come out with vise grips and twist. With pulley on new alternator hold rule, center line of pulley, on dimension you got on fan pulley and crank pulley center line (should be same) see how much you need to get to the front of mounting position on new alternator. Measure from the radiator back to front part of bracket, write that dimension down. Take a reciprocating saw and cut cross piece out, close to the back part and close to the front part. If your bracket is like mine it was all one piece, You got the front part that mounts to the water pump, a cross piece that ties to the rear part that bolts to the block. ![]() ![]() The alternator pulley needs to be the same dimension. Measure from the radiator (the radiator is a stationary point of reference) to get you a dimension to the center line of the crank pulley and the fan pulley, (this dimension should be the same) write this dimension down. And best of all it works!!!įirst you want to purchase one wire GM Del-co alternator with internal regulator and pulley. So I used what I had and it don't look bad at all. Special thanks to Ray Clark for all his information and his input. I'm going to try to explain what I done to complete this project. Here is my old post about conversion!īoy it was a booger. Most do, and you will not need eternal voltage regulator! Keep us posted! First of all does your alternator have internal voltage regulator?
