Took the oil pan off my second bike that I havn't gotten running yet and found these little gems. Im assuming its not a good thing......but im just curious what they might be and the implications.... I will probably be tearing this one down anyway so it will be good to know whats in store.

Whoever can name both these shards will recieve a 750 motor in the mail to rebuild and return upon completion postage paid! Good luck. $:-\$

I think you are the proud owner of a money box, I will skip the prize thank you. (unless there is a lot more in there)

My bike only dumps pennies and the occasional nickle... I never get whole quarters!

I think you've found the goose that lays the golden pieces of change and random bits of metal!

Ratfink · « **Reply #3 on:** September 13, 2006, 10:43:16 PM »

I guess I should have been more clear.......

The quarter came frome my pocket. Is that enough to fix the damage?

scunny · « **Reply #4 on:** September 13, 2006, 11:17:06 PM »

bugger, I thought that was too easy.
OK, could the one on the left be a bearing shell, and the other looks like a piece of aluminium tab thingy

I hate to be the one giving any wrong advice, but the bit on the left looks a bit like the top edge of a piston???

If it is I'm amazed it got to the oil pan.. the other piece looks like a tab from the rear of the head - and if it got to the oil pan somebody must have put it in there.....

Really interested to see the inside of your motor now??

I think they are both bits of piston and the cam chain has been trying to eat the one part

Jay B · « **Reply #7 on:** September 14, 2006, 05:07:24 AM »

The peice on the right might be a chunk of piston webbing or something, but the peice on the left looks like the end of some threads, maybe the end of an oil galley plug? Also the diameter looks too small compared to the quarter to be a piston peice. My .02.

KB02 · « **Reply #8 on:** September 14, 2006, 05:15:07 AM »

I'll agree with Jay with the one on the left. Clearly it was part of some threaded thing at one point in time.

As for the one on the right, it could well be a piston part, but as it was mentioned, it looks like it might have been chewed on by a chain at one point. Part of the housing around the primary chain? Or the Cam chain? Chain getting really loose and popping something off?

The two peices that you found in the oil pan are called indicators. In this case they indicate that you will be tearing down an engine, and spending LOTS of quarters.

[/quote I agree about the left piece having threads and being a piece of the main galley plug. The other looks like a piece of internal webbing.

On the good side, I don't see any part numbers...

I'm not too sure about what size is a quarter coin, but could the left piece be part of the thread off a tappet cap? It's certainly not unknown for them to break when (over) tightening them and they've a short large diameter thread. I'm blank on the other bit.

nickjtc · « **Reply #13 on:** September 14, 2006, 01:04:06 PM »

If these were the only bits you found then the plot thickens. Chunks this big would suggest the possibility of a catastrophic part failure somewhere, which would mean that there should, pehaps, be more bits inside some where.

Was the bike parked as a runner, or did it 'stop working' at the hands of a PO and then get parked? Does the motor turn over? Having asked that I would suggest that maybe you shouldn't try and turn it over in case there are broken bits enmeshed with other internal vitals.

I concur!!

Oh! it was you that bought that engine off me.

Ratfink · « **Reply #16 on:** September 14, 2006, 05:01:38 PM »

It was parked as a runner twelve years ago. When I brought it home I turned it over...and over....and over. The only way I couuld get fire was with starter fluid. Sounds like its mostly intact....

Tapped cover thread might be a good guess..Ill check.

Ernie · « **Reply #17 on:** September 14, 2006, 05:14:33 PM »

trouble in your tranny

the first part looks like the bottom of the threaded oil filler hole the second i dont even have a guess for

upperlake04 · « **Reply #18 on:** September 14, 2006, 05:26:56 PM »

see anything similar here?

bryanj · « **Reply #19 on:** September 17, 2006, 01:59:04 AM »

Look at the bottom case picture and at the top of the centre main, there is a "tab" that cold be the flat bit and its about where the camchain runs which would account for the grooves. No idea what could have knocked it off or what the result would be, probably only there to stop the camchain dropping down or "walking" round the crank if loose. Still no idea on the other bit though

Sure looks like that's it to me.

Everyone has had good ideas, but I say no matter what, finding #$%* that big in the pan means there's more #$%* inside. And that means opening that sucker up to find out how bad it really is.

I agree 100%

gtyler5 · « **Reply #23 on:** September 17, 2006, 08:12:11 AM »

Yes I agree, take that thing apart!!!!!

Ratfink · « **Reply #24 on:** September 17, 2006, 08:30:12 AM »

Nooooooooooooo o o o o o o o o o o o o o o o o !!!!!

Im about to move so it will be some time till I can. Be sure I will keep you updated.

I think you are right about that tab. I did notice when I took the pan off that the plastic guide for the chain was chewed around the edge.
