Uh-oh.

Bob, what is *THAT* thing?

Edit: And, why are there scrape marks on the *inboard* part of the crank flywheel starter teeth?

That's an odd looking oil filter. I never saw one with the magnet at the end like that. I don't think it's new and could be an original early magnet style.

Well that’s interesting you say that. I hadn’t noticed that. You know, maybe that was original. It would explain something that had me scratching my head. That gasket sealer that had been brushed on , had spots where it had ran and the direction of the runs was UP.
That is to say, it looks like the gasket sealer had been applied to the case when the engine was out of the frame and inverted upside down.
 
Yes, you could be the first guy in there since it left the factory, lol. Although you think someone would have checked/cleaned the filter during the break-in period, but I guess you never know. The factory did seal the gasket with sealer but on the later models I've been into, it was only applied to one side. Maybe in the early days, they did both?
 
Ok 2M, you had me going this morning. I almost choked on my bagel when you pointed out damage to that ring gear.

Here are a couple more clear images. I have since flipped the motor and you can see the mysterious object was just an obstructed view of the oil passageway that leads into the sump plate. And that apparent damage ( it really did look that way ) is really just a beveled edge on that gear that had oil clinging to it so that it reflected light at odd angles. It is perfect, with no damage. Yay!

Also I just noticed this. Sometimes we find mysterious flakes of metal , sometimes pretty large and worry something is falling apart.
Look at this spot on the case, there are a lot of imperfections in the casting. Here you can see where thin spots have delaminated and flaked off.

I suspect there are many such spots inside the case.
 
That's one of the things that leads me to believe these are high mile break-in motors. I think it could take as much as near 20K miles before they're done shedding various bits, lol. My filters are finally coming out relatively clean at around 30K miles. I realize much of what I initially was finding was old accumulation that I was just now getting flushed out, but some could still have been new stuff.

This is one of the reasons I like to drop the filters at every oil change. More work, sure, but I want/need to see what's in the filters, or not in them. One of the steps I've taken to ease/expedite the job a little is to acquire some spare filters and sump plates. That way, I have clean, ready-to-install replacements on hand when I do the oil changes. Then I can clean the ones I took out "at my leisure" and have them ready for next time. Sump plates, many times with an old torn filter still attached, can usually be found on eBay for around $20 or less.
 
Well no, 2 magnets isn't odd or rare, but they're usually opposite one another on the sides of the filter. What is odd is your one magnet on that angled end area. But, that might be a good thing. That's a spot that's prone to tearing. Maybe yours won't so readily do that with a magnet blocking flow there.

Man! I have no luck with Phillips head screws! I knew those real long skinny screws that hold the starter motor together we’re going to be tough to break loose. So for two days I’ve been soaking the end of the screws and the screw heads in penetrating oil. Today I decided to try and break them loose. I’ve had pretty good luck with using my cordless drill as a sort of ratchet gun. That hammering motion is pretty good at breaking things loose. So I start at a real low power setting and just kept stepping it up. Finally I reached the highest setting and one popped loose, then I tried the other and the screw head immediately stripped.

So now I have to see if I can find that odd ball screw somewhere. 5mm x 10.5 CM

If not, I’ll just put the good screw back in and call it a day. :shrug:
 
Now it's time for the easy-outs. I have an old, old set that's square-shaped (as opposed to a kind of backward drill bit-looking thing). I bought them ages ago, and never used them until recently. Hammer the right size into the stripped fastener, and turn it out with an adjustable wrench. Easy. Out. You needed new screws anyways.... :banghead:
 
I do have a set of JIS screwdrivers. But these screws wouldn’t budge, that’s why I was trying the power tool approach. I’m having a hard time finding a suitable replacement. It looks like I can get 5mm stainless threaded rod in a length that would work. A little wonky. One things for sure. I’m not doing anything more until I have a suitable replacement in hand. I know the starter works, I was just going in for a look see.

Bob, I really like your how-to thread.

I’m happy to hear you’re enjoying reading my mis adventures. Haha! I’ve got a lot of time now to work on this old thing so I get to post pretty frequently. It’s been fun ( so far ).

Now it's time for the easy-outs.

Actually I think if I decide to go ahead and finish taking the starter apart, I’ll just drill the screw head off. That would allow me to pull everything apart and then put a vise grip on the screw stem.
 
Bob, we all have mis adventures working on these old bikes, some of us just don't post them. (me :notworthy:)
Didn't Jim54 have a solution for these starter screws?
