oil pump gear orientation
oil pump gear orientation I am installing my melling oil pump and I was wondering if they slot in the driven gear needs to be oriented with the keyway? I was thinking 180 from the key or maybe it doesn't matter. Why is this slot there anyway? Also this isn't my pic, just borrowed it, I have the newer 10296 w/ countersunk cover.
There was a thread in gen3 internal eng a week or 2 ago about oil pump driven gear orientation and they said the driv gear does matter as far as which side faces front and back ,,,,,,,,,,,,,I guess 1 side is beveled a little . I believe it was the side with the dot faces the cover . I'm gonna see if it's still there so I can be sure of what I'm saying .
The larger gear inside the pump has a beveled edge on both side. One has slightly more of angle then the other and that one goes towards the front cover. The smaller gear looks to be installed either way. Either gears have any DOTS on them. The groove in the smaller gear I have not figured that one out yet. George @Melling has yet to inform me on that.

Yes this this helps alot. Thanks. I went ahead and oriented the slot with the key.
I was also told elsewhere that the slot was used during the machining/manufacturing process. If George at melling told you it was the OIL RELIEF/FLOW drain then I believe you.
