I started this journey this morning. Here is where I stand as I am not sure what pin I remove.

Removed a few parts. The very bottom pic had a pin but I am not sure if it's the one smooth is talking about.

I think he's referring to the starter shaft pin (part # 2 on the fiche) in the case. Here's photos from my 500 but it should be the same.

The first is with the case split looking at the top half. The second is a closeup of the bolt with the retainer washer and the third is your photo marking where you should be able to reach it from.

Thanks Bagger. I got it all out. Took a few minutes of wiggling but she is out. I think she is in good shape. How do I inspect? First pic is of the pin and where it was. Second pic is how the starter clutch looks. Now this is out of the 77 550 I'm parting out. There shouldn't be an issue swapping it into the 75 correct?

Also the entire process took roughly 2 hrs. I had to drill out several bolts though. I think I will order new gaskets and start the break down process on the 75 550 this afternoon or tomorrow.

Thanks Dave for showing me this thread and XSmooth for doing the process and documentation!

Ill triple check that's still good in mine I suspect the screws just came loose they didn't seem to have any threadlock on them so that's probably why it happened we will see come tuesday or wednesday when I reassemble damn I need a garage haha on a side note I may have located a second gas tank in my pops junk filled garage

I'll answer this question myself it needs to be removed for more clearance to put the clutch all back in if u don't you'll sit there trying forever hahaha like I did til I took the pin out n moved the starter gear up that little half inch is a gift of the gods

I know its been a few years since this was posted but I'm about to try this out.. After going through the comments I have one question, if I use a threaded bolt to remove the primary shadt from the clutch side, do I even need to remove the oil pump?

Thank you,

Its a good idea as you can damage the oil pump gear putting the primary shaft in as its not a free fit whilst you can rotate the pump body to mesh the gear on other side
