I did not have engine at 15* atdc on #1 when removed. When i pulled pump out i made sure not to disrupt the sprocket or shaft on the pump in case i had to reinstall for reasons like this. I have seen locking tool and plan on improvising with a wooden dowel that I'll put a slit in. What is the procedure i should do now knowing i have removed pump in a random spot but did not disrupt sprocket or pump shaft?
