Question and Answers

Q:

Why does my starter armature shaft keep breaking?

A:

Thank you for your question on the starter shaft breaking on the Kohler engine SV735.

It sounds like you may have the wrong starter for this model engine. It may be in a bind when you go to start the engine.

Please send me the complete model and serial number off the engine and I will check to see what part number starter it should take.

Looking up the standard starter for the SV735 it shows to be part number: 3209803s which is a sub for 3209801 and 04 starters.

Please let me know which starter you are getting.

Sam A.

Thank you for the update on the starter shaft breakage. Thank you for the model and serial number of the engine. I all my years of servicing I have never seen a starter shaft break so this is quite unusual. Is the Bendix drive breaking or is it actually the armature shaft of the starter motor. If there is any kick back when it starts then perhaps the valve gap needs to be checked. If you have the ability to check them it may not hurt. In the mean time will check with the vendor to see if there have been any issues and to see if they have any idea why starter shafts would be breaking. Both the intake and exhaust are .004 to .006.

Thank you big uggy for the comments on the starter shaft. I agree that pictures if possible may help to narrow down the problem. I have e-mail out contact at Kohler and am waiting to see if he has any insight on this problem. Sam A.

Thank you for the details in the update. If the fuel was flooding the carburetor it may have, at least in that instance, dump raw fuel into the cylinder and when you when to start the tractor the piston were trying to compress the liquid fuel. How that would of caused damage to the point of bending the crankshaft and causing a bind when the engine is running, I am not sure I can believe that scenario. But I guess it could be possible. Has the engine ever backfired hard? And did you have any gas in the crankcase at that time? What do you other guys think? Sam A.

Thank you big uggy for the comments and I agree that the hydraulic lock is not very likely on this size engine. However I have some good news. I have been working with the vendor the last couple of days about your problem with this engine and he has agreed to send you a new starter and ring gear to see if that will solve the problem. What do you think big uggy. Does it sound like this may solve his problem? If you will send me you mailing address to my e-mail address I will be happy to have these parts sent to you. Please send me your address directly to: sande38@searshc.com I am also working on having a Sears’s technician install the parts but that will take me a little longer to get done and I am not sure I can swing that. But at least you will have the new parts from Kohler. Please do not put your personal information on this site. I hope this will help. Sam A.

Thank you for your comments big uggy and one of my concerns is if Gregory has the puller needed to remove the fly wheel to install the ring gear. That is why I was trying to see if I could get a technician to do the replacement of the ring gear and then check the tolerance between the ring gear and the starter gear. I am not sure he could check the run out on the crankshaft in the field. Thank you again big uggy for you comments and now I am waiting for Gregory to send me his address so we can start the process.

Thank you for the update and I will wait for the pictures before I respond to the engine vendor. He will likely want to see them. Can you also tell me how old this tractor is? Sam A.

Thank you Gregory for the pictures of the fly wheel and starter parts. And also thank you big uggy for the information on the possible cause a solution for the problem. I have forwarded the pictures onto Kohler for the rep to examine. I am also waiting to see if he has anymore recommendations for a successful repair. I have already started the process or getting Mr. Blount the parts from Kohler, and sent in the request for the Sears technician to do the repair no charge. I have also requested that the technician check the engine for any possible reasons for the cause of this problem and to check the flywheel for any binding side pressure against the starter gear as it rotates when turning over the engine before reassembly. Thank you big uggy for the suggestion that the technician may have to put some spacers on the mounting area to achieve the correct spacing between the ring gear and starter. This process may take a few days to set up and implement and we first want to make sure that the parts are at the house before the technician arrives. Please let me know how the repair goes and if the technician discovered the reason for the problem. Sam A.

Good Morning Bruce. I can understand wanting to replace a broken starter shaft on the Kohler engine and it cost a lot of money on a fixed income. If you send me the model and serial number of the engine I will see if they will help you. I cannot promise the results but I will be happy to try. Sam A.

Thank you for the pictures Bruce. I have not had a return call from the Kohler contact and because of that, this morning I e-mail the vendor contact and I should receive contact from him later today. The summer timer is very busy for the lawn and garden industry and it is possible that he was not yet received my message. So the e-mail may get sooner response. I will let you know as soon as he contacts me back. Sam A.

Bill: The engine revving up and slowing down could be caused by the governor mechanism itself. It could be internal or external. The governor springs may not be connected properly or it could even have a carburetor issue causing the engine to slow and speed up. I strongly suggest taking the mower in for repair. If the engine revs to high, it could cause damage.

Ignition module 917276906 Craftsman Tractor

A:

Sorry for the confusion. Look at the serial number on the engine instead of the tractor frame. The engine should have a separate serial number that fits the format described above.
