Tecumseh ohm155 204502a rod ?

[cfish]

My lawn mower threw a rob the problem is the rod part number had three different sizes
On the original rod it has 25-0-44 does this number have to do with chiseling the correct size rod

The numbers molded into the rod just mean something to maybe the factory. Just order a replacement rod by using the model and code off the engine, and ignore the numbers on the rod.

I would but it has diifferent rod sizes for the same model .10 &.20

The 10 and the 20 are for undersized crankshafts, which unless you have had the crank turned, then just get the standard size rod.

Thank you all for the help I will order the original parts

:smile: My question is, why did it throw a rod? If it were me, I would mic the rod journal before ordering a rod . ILENGINE< I meant to quote cfish and not your post. Sorry about that. Don B.

I have no idea why it threw a rod the guy i bought it from said it was fine when it was put away last year by his kids
I pulled the oil it was dirty so it had oil

Is there any way you can post pictures of the crankshaft and the rod pieces. It will go a long ways in figuring out what happened.

I can get some pictures

Aluminum transfer onto the crankshaft and smearing of the aluminum in the rod journal show lack of lubrication failure.
