Question about bearing inserts on Kohler K301

I found a place that supplies automotive like bearing inserts for K series engines. Anyone ever use these? My "freshly overhauled" K301 had the crank journal .015 to .024 undersized and is not usable in its current condition.

About 2/3s down.
 
If you would read some more on that web page, you would find that the rod has to be machined to accept the insert bearings.
 
I know that. Since you don't have to buy a new rod (they machine quite a bit off your old worn rod for the inserts) its comparable to what a new Kohler rod runs ($40).

I called them a few minutes ago - they want $25 to machine the rod and $25 for the inserts (to go .030 under).
 
Are they going to Magnaflux your well-used rod to make sure there are no stress cracks in it......or do you just feel lucky? LOL
 
I use one in my 126 pulling tractor for higher rpm but I dont see a need for one in regular applications. Like Steve in MO said you have to send the rod to a machine shop to have it altered to accept the insert bearing. DAve in MO
 
The cost of the replacement crank is the only reason I am considering this. When you can find one they are usually around $100 - $150+ on ebay and you are hoping they are standard or can be ground to .010 under and not as bad as the one you have. Coupled with the cost of a new rod I'm ahead spending $55 on the current rod (almost new .010 undersized put on the engine by the last owner without fixing the crank) and having the high quality inserts.

I take it you've had good experiences with their shop? They can't be putting out crap if their set ups are holding togather at 5000-6000 RPM.
 
Was a thread couple yaers back about using Allis G insert bearings on Kohler rods with under size ground juornals. Continental and AC part numbers were given
