2005 Cub Cadet LT1042 Slight Knocking Noise
 

Hopefully this is not a rinse and repeat thread. I have a 2005 Cub Cadet LT1042 with only 225 engine hours on it. I noticed recently that there is a slight knocking noise when running but it seems to be intermittent while running. I checked all the issues know to this situation and cannot find anything related. Things I have gone over such as Engine Frame and Head Bolts, Deck Spindles, PTO assembly etc...and cannot find anything loose.

No engine case cracks or oil leaks as well. I take excellent care of the mower and due its routine maintenance. It sounds like a rod bearing but I could be wrong. No flywheel key issues all seems tight under the hood.

:bigthink:

The only thing that I can offer is that the infamous Kohler Courage engines are known for the bolts (#13) holding the top and bottom crankcase halves together come loose and eventually the case cracks,
but I do not know if any sounds precede the upcoming disaster. Something you could check.

Hey Ironman, Thanks for the tip but all of those were verified and were tight and have no signs of being loose.:bigthink:

One thing you could do is remove your deck entirely and drive around and see if you hear it. If it goes away you have likely eliminated an engine issue. A bit of a work but also a good time to do some deck maintenance.

Hey evhevh.

Yep, good thought I will give that simple trick a try.:biggrin2: I did the deck maintenance in the spring BTW
