IH 474 tractor, timing issue

Donkeyguy203 · Jul 3, 2017

Hi everyone. We have a 474 international which as I understand should be the same as 584. The problem is, we took off the injection pump to have it rebuilt as it was leaking. The tractor ran perfect other than the leak. When removing the pump I was not sure to losen the middle big nut or the three other smaller nuts (inside the engine). I losened the the three smaller bolts and in doing so I believe i moved it from the original position within the slots. I tightened those nuts, removed the old pump, installed the new pump. It ran however not right. So i played with the adjustment on the two bolts that hold it on to the tractor as there is play there. Got it running ok but it smokes and lack of power. So, I have spent many hours online looking for the specs on how to time the engine. I do see lines on the front pulley and a pointer. Also as i looked up service manuals, im not sure if they would even have the info i need to get this tractor back timed properly. Hopefully someone on here could give me a bit of help. I am new on here, thanks

There's a scribe mark inside the pump side cover that is used for correct timing, when aligned just above even with the timing tab inside then front pulley pointer should be at either 14 or 16 degrees BTDC, need to check the service manual to be sure. Most cases the pump hub three bolts should be left alone, and the shaft nut and washer only are removed leaving the hub to gear setting alone. Hub will now need reset to get the timing back to 14-16 degrees
