DH, yes you are correct. i was not in full agreement about using the timing window since most people on here doing this need the simplest version and may not fully understand the position relations in the pump. however, while i will say yes i have seen many with no red paint left on the tooth, i...

yes, i get that. but since the designer was thoughtful enough to put a mark on the HH gear, why even take the pointer cover off?? by the way, the reason that the red tooth is used is so that the cam for the HH piston will be at the lowest point, making it easiest to reinstall the head. this is...

the timing pointer in the window does not even come close to lining up when the HH is propper position to be removed. it is only for crankshaft timing. so at best you would just be guessing. if the red scribed gear is used there is no error at all. granted some trucks may have been put togeather...

you are right on chris. maxspeed250, however smart he thinks he is, is completely wrong. the tooth with the line is to ensure the arc is in the propper position. any other spot will damage the pump. tom

well yes that is right but that's the point! not everything lines up at the same time! checking the injection timing is one thing, and may be done to confirm the settings, but servicing the HH is another matter entirely and is not really related to the overall timing as nothing changes when...

chris, no this is where some people get confused. the mark under the small cover with 4 bolts is a timing mark to time the entire pump with the engine. the red tooth with line scribed on it is only for servicing the HH. when the red tooth is lined up the HH should lift out easily. now if someone...

maxspeed250, your info is very wrong and may cause someone to damage their pump. you MUST line up the scribed (red) gear tooth with the pointer for internal components to clear when lifting the head. any other position will do damage. perhaps you or someone else before you damaged your pump and...

do not line up the timing marks. line up the red tooth and pointer. they are different. tom
