I pulled the head on my d15 and am about to reinstall it. Like the good ricer that I am, I read the manual's install procedure.

It stated to align the dowels and oil jet and to replace the oil jet o-ring.

This is probably a stupid question but I would rather not have to take the head off later if I did it wrong:

Replacing the oil jet o-ring is only necessary if I pulled out the jet and reinstalling it right? The o-ring is underneath the jet right? So I should just reinstall the head and not worry about it since I didn't touch the jet correct?

And in case any of you are wondering no it is not a mini me, I did not pull the oil jet out, the stock d15 head is going back on.

 

you are fine, the oring is under the oil jet

 

Thanks
