Dropped piston clip in crank shaft

Recommended Posts

While installing my piston in my 2007 rmz250 I dropped the piston clip into my crank shaft how can I get it out without spitting the cases?

Can you see it?  Magnetize a thin metal rod (coat hanger)

If not, you could try a blast of compressed air, might work but, might also wedge it...

Had a paper towel but it slipped through

I thought about taking the engine out of the bike flipping it upside down and try to shake it out thoughts? I can’t see it.

Yes that might work but try the magnet first.

I did the upside down thing once, added fuel first, it came out. CR80 rd. Never forgot to use a rag around the crank after that either :D

Where did you add the fuel? Because it’s in the bottom of my crankshaft.

Big difference with a 2-stroke as the fuel won't leak out of the engine side sump as you pour it in.

In this case, the crank is within it's smaller separate 'sump' from the gearbox but it isn't tightly sealed

so the fuel will leak into the rest of the engine and contaminate the oil.

 

It could help 'loosen' the circlip though if it's clinging onto an oily surface, I guess anything is worth a try before committing yourself to split the cases.

 

Do you perhaps have any other reasons to consider splitting the engine?

High hours on the crank/rod, gearbox/shifting issues etc.

That could make the venture feel like less of a 'punishment' for you!

Sorry, I think the world revolves around 2T's, forgot the OP has a 4T.

I have no other issues how hard would it be to get residual gasoline out of the engine all the oil has been drained already? Second account btw.

I'd magnetize some wire first. Didn't even think of that when I was 12 :D

I didn't have help. My transmission locked up at one point, the CR80 83 model. Couldn't work it out, so split the engine to have a look. My new sump plug was too long 😂

I always learnt the hard way.

The problem is I have no clue where in the crank shaft it is. Also my whole crank in magnetic so I won’t even know if I found it.

Gas will evaporate.......

The gas will te but the small amount of oil left in the engine that is contaminated won’t.

If the crank is magnetic, I'm thinking It'll be on the crank :excuseme:
