Dropped wrist pin into crankcase……..

[Redman]

Good idea to remove the pan and clean it anyway. Check the oil strainer while there, it's possibly needing a rinse.

Was a bit of thick sludge. Some chunks of gasket scrapping (cam cover maybe). And a oring a bit smaller than intake boot oring (??? dont know what that would be).

Get a new oil pan gasket on hand. Mine was a real chore to remove, about 50/50 stayed on the pan/bottom of engine. Scraping gasket residue on your back for hours is not a fun time. Sorry Dave. Bummer.

Mine stayed 95% on the pan.

Try turning the engine slowly, it might fall through.

There's not that much that would have it hang up, trying to visualize what might be there to have it get stuck.

Try using a mirror and flashlight from underneath, if you have one of those adjustable mirrors on an extendable arm, they are awesome for tasks like this and they save your back.

Good luck,

David.

Failing that a camera.

snagged up under a lobe on the crank probably. May take a little crank movement accompanied with a pencil magnet

I know it not hung up on crank or sometime, I know is on bottom of crankcase, I saw it on bottom under #4, and then saw it roll over to #3 area, and not roll back when tilted bike.

Have turned crank a few times to get different view past the throw/conrods.

Yep, such a mirror is my next plann.

Interesting about the scope for $35

[oldGSfan]

Just spit-balling but could you try to 'flush' it out with some kerosene or something? maybe a squirt bottle (like a bicycle water bottle) to aim at suspect places? Some liquid that would break its bond with any sludge it may have stuck to, but not be detrimental to the innards?

Edit: Oops I was thinking it was a circlip not the whole pin, for some reason not including bourbon.

[roeme]

Pan gasket can be reused in a pinch, no?

But...looking at the exploded view drawing of the engine; it looks a bit complicated (if possible at all?) to shake/roll/fumble the pin from #4's bottom over and into the pan? It looks it could be stuck (sludge, as previous poster commented) to or around a crankshaft bearing wall (not sure how to call it).

I have yet to go into an engine that deep and have no idea about the size of the wrist pin or how it all looks in reality, so I could be completely off.

[Buffalo Bill]

I should look into that more.

Is it related to that obvious bolt head?


(See better in other pic)

That seems to be fairly accessable. Yah, since ordering a pan gasket, I could look into that shift spring.

I think that big bolt cap is the access to the detente pin and spring.
Parts 19 thru 22 on the gif I posted.

PS: Probably the wrist pin is sitting on a ledge near the last place you saw it.
Best 'O luck tweaking it out, kinda like an arcade game.

Quick update: found it. Retrieved it.

so, that was a days delay, of the two days I had to work on this.
and now have more to do (reinstall pan, reassemble exhaust).

more later.

now, let’s see , where was I…….

So that's it? Not going to tell us how and where you found it or how you removed it?

Ahh, Larr, you should know me better than that.

Yah, I am gonna yack at y'all with a long story and pictures.
(just wanted to make some reassembly progress first....)

[Redman]

. . . . . . . tell us how . . . . .

Went to home depot and found a magnet on a probe. But no mirrors.

Went to adavanced auto and got an arsenal of mechanics inspection mirrors and grabber-reachers.
Didnt get the 1 1/2 x 3 inch mirror, that seemed too big.
But got the 2" round one,
and I had a 1" round one (that I thought would be too small).

. . . . . . . tell us how and where you found it . . . . .

Using this third eye



Actaully that mirror (2") was too big to maneuver around, down in there, in some places, so also used a smaller one (1", not shown).
Took a lot of fussing around to get mirror and light and eyeball in a position to see in a particular direction, then to look in next direction took some more fussing around.....

Looked around in the bottom of #4 (where was last seen) and #3 (where I thought it rolled to, and didnt roll back when tipped bike/engine). Took quick look in #2 and #1. Tryed looking up and around from underneath with pan removed with out much success.

THen turned crank 180 so that throw/con-rod moved from front to back (or back to front), and then I looked around in those other areas with mirror & light.

ANd saw it down in #4 up against the outside wall. WHich surprized me cuz, originally I saw it roll from 4 to 3, and didnt get it to roll back that I could see.
I dont know why I didnt see it first time I looked in that direction in #4. Is kinda hard to tell what are looking at.
And, I had been convinced I last saw it roll from 4 to 3 and not come back to 4, so thought it would be down in the deeper part under #3.

With a little manipulation with a reacher-grabber (not shown) I got it to move a little bit (see pic) to where could get with magnetic probe and pull it up and out.

[Redman]

So, now back to the project thread.

Great job!

$hit happens, it's how we deal with it that matters.
