Does the end of 1100 crank need to be plugged when removing pulser shaft?

Like the title says: Does the end of the 1100 crankshaft need to be plugged when removing the pulser shaft?

JBz mentioned it here (sorry about quoting you).

I examined the recess in the end of the crankshaft and can't see anything that looks like an oil passage so I think it will be OK but I want to make sure before I start making the plate to cover where the timing chest used to be.

I think Wingrider covers it but for an 84 1200. Nit sure the question you ask is answered, but---viewtopic.php?f=30&t=43506&start=210

As Eric pointed out, I did the cover on an early 1200 engine. Not absolutely sure I needed to, but felt it looked better finished. This is the link Eric posted. viewtopic.php?f=30&t=43506&start=210

Easter ended up using a bolt and washers in place of the cover...I'll see if I can find a shot of his.

This link is the only picture I could find of what he did. https://www.ngwclub.com/forum/viewtopic ... 10#p696210

Perhaps a message to him might yield more info.

I hadn't thought of using a bolt & washers. That would work but I still think I'll make the cover. My cover will be similar to yours except less elaborately shaped since I will be cutting it by hand (actually cutoff disc in grinder).

But what about the end of the shaft? Why did you cut the pulser shaft instead of just removing it? Is there an oil passage in the crank that I am not seeing?
BTW: I sent a PM to Easter to ask whet he did.

[wingrider]

That is a good question, and to be honest, I don't recall why I didn't just pull the shaft out. Something tells me that I thought perhaps it was in relation to the thought that there might be some type of oiling trouble if I didn't leave it. Been to long ago that I did it, and can't remember what it all looked like in there.

Easter tells me he didn't plug the end of the crankshaft. My buddy who has had more engines apart than me had a look and he can't see anything that looks like an oil passage either so I'm just going to leave the end of the crankshaft and put a plate over the hole in the cover.

I have been thinking a bit about this, and think it may be unique to the 84 1200 engine. The 1200 crank has an O ring on the pulse generator shaft that most likely was restricting the amount of oil coming out of the crank.

[Sidecar Bob]

The 1100 has an o-ring on the pulser shaft too. My buddy & I figure its there to help keep it centered in the hole and maybe act as a sort of cush drive. We both looked in the hole with a good light and neither of us saw anything that looked like an oil passage.

Like I say, it might just be unique to the 84 1200...
