No you dont need to touch allen bolts. There are 4 12mm bolts. You need to follow manual from quickserve.

When you put back tappets to the pump make sure you put in same orientation. Each tappet has grove, it has to go to the guide pin in the pump body. The guide pins can be easy turned with finger and have to be in vertical position. Otherwise you can damage the pump.
