Thank you for your question on the Tecumseh engine on your Sears lawn mower.

It sounds like you hit something with the blade and sheered the flywheel key. Unless you bent the crankshaft above where the blade adapter is located then I would suggest replacing the fly wheel key and the blade adapter and blade and it would have been okay.

Since you have taken the whole engine apart the cam gear will have a mark on the gear like a dot and the crankshaft gear that mates with the cam gear will has a mark and all you have to do is align the two marks when you put the engine together.

The flyweights on the oil slinger sound normal to me.

From all the details you have given me my only concern is if the crankshaft is bent. If it is then the engine is not worth repairing since Tecumseh is no long in business and it may be hard to find a replacement part.

Please let me know what you find out.

I replied earlier to Sam A. that my cam gear has eight dots on it and there is a short line on the crankshaft counterweight. Are these the marks one lines up, if so there are 8 different points to mate the cam gear to the crankshaft? Also, there is a 1/8" hole in the cam gear, is this the hobbing hole? There are three steel dowel pins, 2 steel dowel pins are part #26727 that are attached to the cylinder and the other dowel pin, which is smaller in diameter at 1/8" diameter x 3/4" long, where does this dowel pin go? Thank you.

I am sorry but I did not get that thread. I would turn the engine over until both valves are closed and then piston is a 10 degrees past top dead center. Then set the timing dot on the cam shaft with the mark on the gear of the crankshaft with both intake and exhaust valves closed. There is a piston and sleeve type oil pump that mounts underneath the cam gear and the ball end of the oil pump sits in a boss on block. I really think it would be beneficial if you had a manual for these old L Head engines so I am going to give you a link to one. Sam A.

Thank you Sam A. for your help, I got my mower running. But when I turned it off, it did not start back. I checked my solid state ignition (part no. 34443A) and I did not get a spark off the engine block, while rotating the fywheel. Is there any other way to check this part or do you have any possible suggestions what can be wrong? Thank you.

I would like to add that I have a book, " Troubleshoot & Repair Any Small Gas Engine", by Paul Dempsey. Are you familiar with this book? The link you directed me to appear to be a good book also. Thank you.

Thank you for update on the mower. If you use a spark tester will give you more accurate reading then if you are just grounding the spark plug to the block. It is a little difficult to check the electronic module. If you are not getting spark then I would consider changing it. Make sure the grounding wire is not shorted. I would suggest removing the grounding wire on the module to make sure. I am not familiar with Paul Dempsey�s work but there are a lot of good troubleshooting manuals for repairing small gasoline engines. I am sure that his is fine. Sam A.

Sam A. my grounding wire was disconnected, the male blade (not the female blade to the solid state ignition), where does this wire connect to, does it connect to the terminal (part no. 610973)? I assume this is what you mean by the ground wire being shorted because it was disconnected. Please advise, thank you. Julius

Look on the engine itself to see if you can locate a model number. Without the model number, I have no way to determine exactly which engine you have. I'll need to know which engine you have to see how the carburetor connects up and if it's something I can get a manual or photograph of.

Thank you for using Manage My Life!

Thank you for your question.

I am sorry you are having a problem replacing the belt. To remove the debris shield you have to remove the blade adapter first. To remove the blade adapter the gas should be drained or ran out of the tank so the lawnmower can be placed on the side. Lay the mower so the carburetor and air cleaner are up.

Block the blade with a piece of wood and remove the blade bolt and blade. The blade adapter should pull off the engine shaft unless it is rusted to the engine shaft.

Try spraying rust buster between the engine shaft and the blade adapter and tapping the blade adapter with a hammer to help the rust buster penetrate. Tap on the backside of the blade adapter to tap it off the engine shaft.

If this procedure doesn�t work, put the blade bolt back into the engine shaft and tighten it until the head is about � inch from the blade adapter. Use a gear puller to pull the blade adapter off the shaft.

With the blade adapter off the debris shield will slide off the engine shaft.

I hope this is helpful. Please let me know if you need further assistance, on the repair of the mower.
