416H K-341 broken rod

Recommended Posts

Hi All, Just fishing around for opinions.... I picked up a 416H yesterday that has a few issues... but the most pressing of which is that it threw a rod. I do have the head off and have removed the piston and rod.... I have not yet pulled the side off the motor yet. I can see that some of the sleeve skirt has been broken off... it may have damaged the block but I cant tell yet. It appears that the crank is still good the surface there is smooth. I dont know about any other parts yet... another given here is... I have a MF16 that still had compression but I have not run it so I dont know it condition. Does anyone have experience on resleevability for these..?? or should I just be looking to rebuild the MF block and use the allis crank and parts etc? I dont necessarily mind the expense of a rebuild but am leary of using a potentially damaged block... Obviously I have all the engine parts from the allis so I think i could just use the crank and all other parts from allis and the MF block... any thoughts... Ill have to post pics... but its 4 degrees now and this week looks like big snow on wednesday... thanks

I agree that Wednesday is supposed to be a big snow day. My wife has been complaining for two days now, ever since she saw the weather report. Sorry I cant add more. I purchased a 7117 with a blown rod and instead of rebuilding the Kohler engine, I repowered it with a 21 HP Kawasaki engine from smallenginewarehouse, seem the fastest route for me. MR

I doubt the block has any severe damage but I can not say without seeing it. Rebuilding these engines is not difficult just tedious to get everything back into spec. I would completely disassemble and measure everything or take it to your local Kohler dealer. The K341 is a great engine as I have two running strong. Brandon

IMO, the stock 341's were good engines and realstrong. But, the weak points were some much stress on the rods that they broke for any number of reasons. If properly edged and not too big of a chunk missing then you could likely run it fine. Till something gets bound up and the new rod lets go.....
