Kohler Courage 20hp SV600 crankcase cracked

6308 Views 14 Replies 7 Participants Last post by  Whirly
I have a SV600-0222 kohler courage 20hp engine with a cracked crankcase. I am finding that the part to fix this is getting a new short block replacement. My question is, on my current top cover of the short block this is stamped "20 499 05 REV D", I found a short block online that is pretty inexpensive with these numbers "20 499 06 REV C". Are these 2 parts interchangeable? I was hoping to be able to repair it with that part but I don't know what the numbers mean and cannot find a cross reference. Thank you for any help that can be provided.

Wow. That other guy is no help. Wtf would sanding it and filling it do? Lol. Anyways, I wouldn't think the block numbers should matter since the first 5 or 6 are the same. If the one online has enough pictures, examine it carefully and compare it to the one you have now to see if anything is noticeably different, besides the crack. I say just buy it if it's cheap enough. But Idk. Maybe try to keep researching it? Honestly for the cost of most small blocks, you might be better off just getting a new engine or find a used engine to fit it. Those Kohler Courage engines are pretty worthless anyways. They have too many problems to count. You're better off with a good Briggs & Stratton Intek single-cylinder or a Briggs & Stratton V-Twin. Or if you want to get another Kohler, get a Kohler Command V-twin, BUT stay away from Kohler Courage engines! Otherwise you may end up with another cracked block. Kawasaki engines are also good too, they are just harder to for an affordable price. Good luck! BTW what machine is this engine off of?

It is out of an Ariens 46" cut lawn tractor. It is over 10 years old but still in good condition body wise.

Actually the courage is a pretty good and the inverted sump (soup bowl) is a better design than what other engines have used for decades. The problem was only due to the front 4-5 bolts not being tightened enough.
Everyone I see from around 200-2003 are loose or already blown up.
Only seen 2 2006s loose and none 07 and up.
If you catch them before the flywheel smacks one and break it off and cracks the block you can get many years out of them.

You can clean with brake cleaner, scuff with course sand paper, use jb weld liquid on it and go over that with rtv and probably seal it to fairly leak free. Clean the top bolt hole threads with brake cleaner and blow dry several times and use lock washers and or loctite on them.

first off I will say ''''''it takes courage to own a Courage''''.. it is no-brainer to repair a busted engine.. ur gonna pay thro ur nose to repair one.. u can find good engines on Craigs list..in the farm & garden section..

the best engines r the Kohler Commands.. they have HYD lifters in them.. u want to run them with 5w or 10w30 oil in them..

WHAT'S UP WhIrLy????
How's them windmills doing in your parts?
I went to Chicago last last fall and saw the whole slew of them in Indiana. Then I went to Greenville Oh which is about an hour from me and they have three of them.
They're coming, they're coming, they're coming for me....Nooooo!!

that may not b true.. they do not put the mills where they migrate.. they also do not put mills any closer than 2 miles from our towns.. lets get back on the subject of this tread..

just to finish this, you are lucky. here in ontario canada they can be as close as 1500 ft from a residence.
I was just looking up the ones in Greenville to see if they were two or three because I couldn't remember and it seems Ohio passed a house Bill in Congress just two or three years ago to require them to be I think a little over fifteen hundred feet from Street front or something like that. They say this greatly discourages future wind farms in the state. I guess people didn't want to look at them and were afraid they would take over and be very visual.
I am so anti government and so anti people complaining about Aesthetics and what they think they get to see when they look out their windows and are out in public, and So Pro property ownership rights that I'm certain I wouldn't agree with this. Even though I'm not super big on windmills. If I owned a piece of property and someone wantedto pay me thousands of dollars a month to put one on my land though I would certainly be very Pro windmill.
Don't really need to get back on topic on this thread as we've already covered the whole spectrum of a cracked Kohler courage block.
