I would appreciate some advice here in timing the cam and fuel injector pump. The technical manual does not describe the timing marks on either the cam or pump gear. I have attached pictures of the gears. The idler is not bolted in, just placed on the block Placing the #1 piston to TDC is not a problem. What marks on the other gears are appropriate? For the cam I can always use the redneck timing method of finding the "sweet" spot where when you rock the cam backand forth the exhaust and intake valves will alternately open and then turn the cam 180 degrees. However for the pump, the only significance that I see is the bolt pattern. Help is appreciated.
Make yourself a V iron with a longer extenion to the bottom.
Like a Y
Turn the crank to no 1 tdc.
Then put that open end on the crank and turn the cam till its mark alighn under that Y. Keep it there. Move over to the inj pump gear and do the same. If its a 4 sil...use the no 4 to alighn it. Now slide the idler in and recheck if its still on ite marks. Then you will be fine with the timing of the gears !
