I have a Gravely zero turn mower given to me and the 18hp courage motor has a crack, did research and found this is a common problem with kohler engines, is there a replacement for the SV540 series ? i am hoping the crack can be welded.

There's been quite a bit of discussion of those engines here. I know one of the regulars discussed repairing them in detail but I couldn't find the post.

There is a Briggs replacement ......... I did a repower not long ago for a guy with a Cub Cadet zero turn..... His Dis Courage engine cracked also.....

The cause of that is the bolts that hold the crankcover / sump get loose and the torque of the engine cracks the block..... I have a few friends that have that engine and they bring them to me 2 times a year to check the bolts and retorque.....

Last time I did it I put BLUE loctite on the bolts......

I'll look in my books if you are interested in the the model of the Briggs engine......

Let us know Mon Ami ~!~!

Thank you, let me know what briggs replacement there is, i am going to see if the block can be welded, if it can be welded i will be using blue loctite on the bolts, would use red, but might need to take apart one day.

I'll find it for you, keep in mind this was for a CC mower... Everything was a match as for as the wiring goes......

A few people on You Tube tried to weld with no success...... I even spoke to a welding specialist here in town on that and he said no go ........

Ok.......... The one I repowered was the Briggs 33S877-0019-G1

I seen in my briggs power portal repower projects that a Ariens / Gravely 915087 was repowered with a Briggs 331877

I would need to know all info on your mower to confirm the engine you need.....
