Tiger Pulleys
A friend of mine bought a TIGER that did not have an engine. He decided to install a 302 but needed a set of TIGER Pulleys. He checked the usual sources and came up with mile high prices for something that is not very high tech. I took on the task of building a set of pulleys for him by first measuring the pulleys on my car and then going out to Pick-Your-Part. I compared the measurements with everything that I could find and came up with the following solution.
Bottom (Motor) Pulley
I discovered that the engine pulley from a '71 V-8 Ford Van was of the correct construction and it's dimensions were close to that of the Tiger.
The Diameter of the pulley was almost exactly the same with only the depth of the body too much. The van also had a double pulley on the bottom.
I machined off the extra pulley and then took a 1/2 inch piece out of the hub body.
The area removed by the lathe should take out the old spot welds but should leave the inner part of the pulley. The two halves then can be knocked apart and cleaned up. When the two halves are pressed back together they can be re-spot welded as shown. The finished depth should be 1 1/4 inches from the vibration damper to the center of the pulley. If care is taken the end product will pass inspection of even the most critical concurs judge.
Water Pump Pulley
The water pump pulley was made up of pieces from two pulleys. The part that bolts to the Tiger water pump is from a Volvo 164 the pulley part is from a 71 Chevy truck.
Chuck the Volvo pulley in a lath and remove the pulley part leaving only a cup that bolts to the water pump.
Do the same to the Chevy pulley leaving the pulley and part of the cup.
The two pieces will fit together with the Volvo part inside of the Chevy. The finished height should be 4 inches face to center.
Next spot-weld the two halves together by welding in one place first and then trying it on a lath and making sure that it is square. Then spot weld in several places.
Then you have to make a centering spacer to ensure that the whole thing is centered on the pump when finished. I used a Volvo aluminum fan spacer for this.
The end product will not be a visually perfect TIGER pulley perfect so you may not want something like this for your pristine restoration but in this case it got another TIGER back on the road.
