I had some problems with mine. If your talking about the seals on the governor cover or that little side plate, then yes, you can place those. If you are going any deeper than that, then I wouldn't recommend it. From what I understand, the internals of those pumps are so sensitive that if the oils from your fingers get in there, the parts "swell" and if you get it back together, the tolerances won't be right. From what I understand though, there are timing marks on everything, making re-installation really simple. The pump goes one way into the timing gear, one bolt holding it on there, then if I remember without looking, two bolts holding the pump on the motor. There is a timing mark around the top bolt, I think 19 degrees btc.
