Front Primary Engine Sprocket fastening?
Howdy,
So I recently sent out my lower unit to be repaired, due to the rear intake bearing shredding, and it came back and now putting it back together.
So when putting on the front engine sprocket, I find it odd that the grooves for placing the slotted lock-washer on are too far in that I cannot place them on.
I noticed the 70's and on use this nut: https://www.lowbrowcustoms.com/2917-...r-1970-88.html without a lock-washer. mine is a 69 933 ironhead.
The lock-washer came off (Meaning I have the part for the rebuild from disassembly), but not sure if it was engaged in slots or the same as it is now, just free. I'm enclosing some pictures to help better understand.
it cant be possible that the shaft is in further than it should be can it? As mentioned, I had the lower end rebuilt by another shop, acid washed, blasted, work parts replaced, new bearings, etc. I can't think it's possible to put it together wrong with the transmission being behind this motor shaft. It also doesn't look that the sprocket could go in any further, and I already tightened it once and then backed off. It looks even all the way across to the clutch, and rides nicely on the primary chain adjuster (Couldn't go any further back before hitting the case or end of adjuster).
Any thoughts? Should i be concerned there's no way to lock the front motor sprocket, etc.? The nut is just a standard hardened flat nut.

You can check the parts that you should have on-line here. There is a similar looking nut shown for your bike.

FWIW...I am no expert on this...
Thinking outside the box.....
Is the sprocket on the correct way?
Does the washer go on the inside of the sprocket?
Any wear marks on the inside vertical surface of the wash where the shaft may spin validating your theory that the washer tangs were never engaged?
Anyway, here's a bump and good luck.
