B&S starter bolt puzzle

[Sean2202]

Greetings,

I have a B&S 18hp V-twin model 350447 type 1116-E1 code 00021111. This is stuffed into a Toro Sandpro 5020. There is very little room to remove the starter bolts. Along the way someone used the wrong bolts stripping the starter mounting threads on the engine. I am going to try to use a helicoil to fix these threads and have ordered new factory bolts and a new factory starter.

Here is my issue:

In the parts manual that I have for this engine it states that both the starter bolts have the same part number 805247. Which I ordered 2. The factory starter that I ordered has a new number 691564. I do not understand how this engine can take the same bolts here as the depth of one of the mounting holes is deeper than the other. It is hard to tell if someone has broken a bolt off inside one of the holes? The last thing I want to do is drill because I assume there is a broken bolt then drill into the engine itself. It does not appear to be broken inside. So I wanted to check with the pros here. Possibly the new bolts are both just really short? There is also a mounting hole that is below the one that the current starter was attached to. This hole is also not as deep as the top one. Did someone use the wrong starter and does the right starter mount to this hole?

The second picture is the depth of the top starter hole. The third picture is the depth of the bottom starter hole. (where this starter was mounted)

Well here is another thing added to the puzzle. Talking to the owner apparently along the way it was discovered that the wrong engine cover was used on this machine. IT is apparently possibly a 16hp v-twin B&S engine? Unknown type-code. This had been discovered during a previous tear down. The serial numbers that were used for parts was 303447-1233-E1. Not sure if this is correct or not? Is there a place on the block that the right numbers can be found? There is not any numbers on the valve covers.

The starter bolts and the starter seems to have the same part numbers for both engines that I listed. I have threaded a helicoil approximately 90% into the bottom hole so hopefully it will hold.

Here is the starter 691564, is this what you got?

Yes that is the one that I ordered from my B&S dealer. Not sure if that is the exact one that came off of here? If you have one could you measure between the bolt holes to see where it mounts to my block.

What exactly is the problem that you are having? The holes don't line up? Or just that you noticed that one of the holes is deeper? Have you just tried mounting the starter?

The screws can should be able to snug up by hand, and you will see that all is well, and then snug up the bolts with a wrench.

Here is the problem,

1. I just found out someone used the wrong cover on this engine so the numbers are unknown. Is there a number on the block for identification to retrieve the correct parts? There is no number on the valve cover.
2. Being that it is the wrong cover I believe that the wrong bolts and starter may have been used originally stripping the holes. I ordered new bolts and starter from B&S but unsure if I purchased the right ones because I used the numbers on the engine that says 18hp but owner says it is 16hp. I have another engine (303447-1233-e1) that is similar B&S that take the same starter bolts and starter which I ordered.
3. The lower starter bolt hole does not have much thread on this engine I was able to get a helicoil about 90% in so I guess that's OK?

These must be really short bolts from B&S to mount this starter.

Thanks for your reply

The original engine used in that sandpro was 350447-0116-E1
Per Small engine wharehouse.

Yes, Thank you for your reply. I believe from what I was told is that somewhere along the way someone took the shroud from that engine and put it on this one. I guess this was found out when the engine went for a rebuild the pistons measured 2.679" which is 16hp apparently and 18hp measures 2.836". This I was told and there is a note on it in the book.

Also It has a steel ring gear. Once again the starter I ordered (691564) along with the bolts (805247) was for 350447-0116-E1 the engine that was supposed to be in this machine that I thought was until this morning. Not sure if those will work on this block ring gear or not?

There is also the possibility that someone put the wrong ring gear on this engine as well. The engine had been out a few times in the notes that I have and this starter has been an ongoing issue for a while now (years according to what I'm told)). I want it all to be right before reinstalling it.

So if anyone knows where there may be numbers on the block so I can get the proper starter, starter bolts and possibly ring gear for this engine that would be great.

is this not the original engine on the piece of equipment?

I am told it is not because when it went out for a rebuild the pistons measured a different size than an 18hp. They measured 2.679 In the notes to 2.836 for 18hp. So what I was told was the shrouds from the original engine were put on this block. Is there a number on the block somewhere to confirm this?
