Question and Answers

Q:

what motor was used when this motor was discontued 27 hp v twin Kohler CV740s

A:

Thank you for your question on the replacement engine for the tractor.

You are correct in that the original Kohler engine is no longer available and neither is the short block.

It may be possible to use a different Kohler engine but you will have to remove a whole bunch of parts off the basic engine and add as many to make it compatible.

I do not know what is possible with using a Briggs and Stratton engine. You would have to change the muffler mounts and many unknown things. The throttle linkage may also be a problem.

In doing the research on trying to figure it out it may not be cost effective to go through all this.

I am sorry that I could not help you with this project.

Q:

head gasket replacement 917.276120

A:

 

 

Thank you for your question.

 

I looked up the mode number you submitted. The correct part number for the head gasket kit is 24-841-04-S. I am not sure why the kit no longer includes the bolts. I double checked the service manual and it does state to use new bolts when installing the head. The part number for the new head bolts is 12-086-16-S. I also looked in the service manual for a model that uses studs. I did not see any in class of engine. They may use stud in another style engine with the same gasket. While I was on the Kohler site I looked for bulletins that say why the bolts do not come in the kit. I did not see any bulletins on this issue. The parts for your engine can be ordered from the following link. Replacement parts for a Kohler engine model CV740-0024.

 

I hope this is helpful. Please let me know if you need further assistance.

I double checked on the Kohler website for any information on the head gasket kit. I could not find anything that says you no longer need to replace the bolts when installing the new gasket. To ensure you do not have a problem with the new gasket I recommend replacing the bolts. I replaced enough of these gaskets to know if you try to cut any corners, they will fail. I accidently reused the bolts one side.(not really by accident I just was not thinking) I figured it would be fine because I torqued the bolts. I was back out for the same problem within a month.

Q:

Need part number for this item. 917.276120

A:

Thank you for your question.

 

 

I am sorry you are having a problem with the engine on your tractor. The part you are looking for is the rubber grommet. The part number for the rubber grommet is 25-313-03-S and can be ordered from the following link. Crankcase breather grommet.

 

If the engine is putting out light colored smoke, it is burning oil. I do not think this would be caused by the bad grommet. Usually on this style engine it is caused by a blown head gasket. The gasket blows between the push rod galley and the piston. This causes the engine to smoke but not loose a lot of power. Without the special tools to test for this the only way to check the gasket is to remove the head. If you remove the head, it is recommended to replace the gasket anyway. The part number for the head gasket is 24-841-04-S and can be ordered from the following link. Replacement head gasket for engine model CV740-0024.  The side that has the blackened plug is the side I would check.

 

I hope this is helpful. Please let me know if you need further assistance.
