I'm stuck, I need help

So I just rebuilt my motor on my 2001 gti, and I cannot get the rotary cover to fit flush against the block. I thought it was the rotary shaft, but I had a dealer replace the rotary shaft and it still won't sit flush. I don't think it's warped because it sticks out about a whole inch, and I can't just run it like this as it would cause a huge air leak. Any help is appreciated
 
Sounds like your oil pump gear isn’t meshed with the rotary shaft. Please post a picture of the shaft without the cover.

Why didn’t they install the cover?
Did they just pull the shaft and put it back in? What did it look like?

Why didn’t they install the cover? How did they replace the shaft without splitting the cases and complete tear down of the engine?
I'm assuming they just pulled it with the cases together. And they wanted to charge an extra 150$ just to put the cover on so I told them not to. It's 4 bolts, they don't need to charge that much. Maybe they didn't even replace the shaft, I am not a fan of this seadoo dealer near me but I'm in a pinch and they are the only ones near me. Maybe I should try moving the oil pump gear around and sliding it on? Not sure what else to try.
 
So did they just pull it out and put it back in? Was it damaged?

And yes their price is ridiculous to put the cover on.

I think a picture would really help at this point.

You found a BRP dealer to work on a 2001 Sea-Doo? I thought they refused this kind of work for several years already.

The dealer was a Sea-Doo dealer?

They replaced the shaft with one that I gave to them. And I will return with pictures later today when I get home.

Yes it was a small shop, has a showroom with about 6 skis and then a building behind it where I believe one guy does all the work on whatever is brought to him. They had all the new models and I believe they are a certified Rotax dealer, but I still doubt their quality

IMG_2440.JPGIMG_2441.JPGHere's the pictures now that I just got home. I'm thinking my issue is that the crank halves aren't lined up perfectly which isn't allowing the cover to fit on. Is there an easy way to fix this misalignment? I tried sanding the lips at the halves and it seemed to get a little closer to sliding in but I'm not sure what to do
 
I just did a swap on the rotary shaft bearings (97' GTX), on the 787 it's different, shorter gear, than the one in your pics. Looks like you may have the incorrect rotary shaft installed.

Well the problem is I'm pretty sure they put the same shaft in that was on the original motor, so I'm confused on how it would stick out farther

Did you rebuild it? or they did? is it the same original motor? possibly, though we don't really know, the original rotary shaft? Verify in a pic the cover you're trying to install. A 787 cover on a 717 would explain the issue.

Ok here's what happened, bit of a long story I'll keep it short. My crank siezed so I rebuilt the motor myself, I tried replacing the rotary shaft during the rebuild but I couldn't get it pulled out. When I had the motor reassembled the rotary valve cover would not go back on, all I changed was the crankshaft and all gaskets in a rebuild kit. It's the original rotary valve cover, and original block. Since I couldn't get the cover on I thought the shaft was slightly pulled and it was sticking out so I sent it to a shop to remove the rotary shaft and replace it with one I gave them. I think they scammed me and didn't replace it, because I also bought a new rotary VALVE which only fit on the teeth of the new shaft, and not the old one. And I'm now trying to put the new valve on the shaft and it will not fit. I also think the problem of the rotary cover not fitting is because the block is misaligned, I can feel a bit of a lip where the block goes together.

Is it just me or does it look like something was bouncing around in the crank case.

yes a bolt got stuck in the rotary valve that's why there is a gouge in the opening of one of those valves, that's not my concern though, I just want this rotary cover put back on
 
What I'd do, break it apart again and double check the rotary valve shaft is seated all the way, engaged with the crank etc. Second, double check the shaft is the correct one for the 717. You stated you gave it to them to swap, where did it come from? you're having issues with the rotary valve engaging the teeth, etc, somethings not right. Third, though I can't see it would be an issue, double check the fitting of the cases.
 
THat is how the shaft looks on the 717 engine because it drives the oil pump too. IF the shaft wasn't in all the way you shouldn't be able to get the snap ring in all the way and your is.

Don't use a rotary valve that is not OEm as some of the aftermarket ones like WSM have the drive teeth cut wrong.

THe only thing I can see is you are not engaging the oil pump gear correctly. Try removing the nylon oil pump gear and see if the cover goes on. Your cases are not mis-aligned as the crank is what centers them so do nto sand them down.

Finally what oil are you using? API-TC oil is not typically blue or green.

Well I do feel a gap between the two cases but I'm not sure if that is normal? Is there an easy way to remove the gear? Yes the PO used the crap blue oil so my next step is flushing that out.

That's exactly what your problem is. There is no way the RV cover will go on with the cases out of line. You have the right shaft and it's installed properly.

I would listen to Chester as he has seen about it all. I use the front timing cover bolted hand tight to align the cases front to back before torquing them down.

Great, so now I gotta pull the motor again ?

The weird thing is, I've never seen this unless it was using case halves from 2 different engines.
