Kohler k241 out of a 1045

Recommended Posts

Question for you guys. The rod on the k241 in my 1045 is shot and the crankshaft is broken at the nut. The flywheel just kind of fell off. Now I know I have to get a new crankshaft, but my question is about the rod. It appears to me that the oil sling on the bottom of the rod is shorter than most due to the shallow oil pan on the engine. I looked at partstree.com and it appears that rod is NLA so my questions is can I buy a standard rod for a k241 and grind down the oil sling or what is best to do in this situation? I'm sure someone else here has rebuilt and engine on a 1045. If this helps the engine is a k241AS Spec 46219A 

 

Thanks!

In case you have not noticed I think the pto end of the crankshaft is 1" diameter. Later models went to 1-1/8" diameter.

Last one I did I just matched it up to the old one and cut it off, ground it smooth just like original

WHX??

:text-yeahthat:I would guess that's what the guys do Mike as the length of the oil dipper is the only difference. I would like to know how did the crank break? I might have an extra crank Mike, will have to check if its inch or 1 1/8" tho.

It appears to be that the PO was on the flywheel nut with an impact wrench assuming they were left hand thread like an old Briggs engine and snapped the end of the crankshaft off.

Get someone to drill and tap it for a bolt.
